Introduction
Certificate of Deposit (CD) rates have experienced a dramatic rollercoaster over the past decade, from historic lows during the COVID-19 pandemic to reaching heights not seen in over 15 years. This comprehensive analysis examines three critical benchmarks: national average CD rates, the absolute best rates available from top online banks, and—most importantly—the “reasonable rates” that real consumers can realistically achieve with moderate effort.
While financial articles often compare only worst-case and best-case scenarios, the reality is that most savers fall somewhere in between. Understanding this middle ground is crucial for setting realistic expectations and making informed decisions about where to park your savings.
National Average CD Rates: The Last 10 Years
National average CD rates represent the weighted average of rates offered across all banks and credit unions in the United States, as tracked by institutions like Bankrate and the Federal Deposit Insurance Corporation (FDIC).
Year-by-Year National Average Rates (1-Year CDs)
2015: 0.27% APY Following the Great Recession, CD rates remained at historic lows as the Federal Reserve kept benchmark rates near zero to stimulate economic recovery.
2016: 0.35% APY In December 2015, the Federal Reserve raised its federal funds rate for the first time since the Great Recession, leading to modest improvements in CD rates throughout 2016.
2017: 0.25% APY Despite the improving economy, CD rates actually declined slightly as the Fed took a cautious approach to further rate increases.
2018: 0.55% APY As the Fed continued its gradual rate-hiking cycle, CD yields began to pick up following interest rate hikes driven by a strengthening economy.
2019: 0.66% APY National average 1-year CD rates peaked at 0.66% in March 2019, marking the highest level since the financial crisis. However, rate cuts later in the year caused averages to decline.
2020: 0.16-0.41% APY The COVID-19 pandemic struck in early 2020, and the Federal Reserve made emergency rate cuts in March, bringing benchmark rates to near-zero levels. From June 2020 to June 2021, the average one-year CD dropped to 0.17% APY from 0.41% APY.
2021: 0.17% APY CD rates stayed near historic lows in 2021 as the Federal Reserve kept interest rates low to support pandemic recovery. In January 2021, the average rate on a 1-year CD was just 0.16%.
2022: 0.16-1.00%+ APY By the middle of 2022, yields on CDs began to rise dramatically as the Federal Reserve began raising interest rates to combat inflation. The year ended with rates approaching 1% or higher.
2023: 1.92% APY The Fed hiked rates 11 times in 2022 and 2023, incentivizing banks to pay more on savings products. In September 2023, one-year CDs averaged 1.92% APY, a significant improvement from pandemic lows.
2024: 2.00% APY Average CD APYs dipped leading up to the first Federal Reserve rate cut of 2024 in September. The national average one-year CD yield stabilized around 2.00% APY.
2025: 2.00% APY (Current) As of June 2025, the national average one-year CD yield remains at 2.00% APY, with the five-year CD average at 1.72% APY. The Fed held rates steady for much of 2025 before making its first rate cut in September.
10-Year Average National Rate: 0.83% APY
Average Annual Returns by Time Period
Understanding how rates varied across different economic periods provides valuable context:
Full Decade (2015-2025): 0.83% APY average
- This reflects the prolonged low-rate environment following the Great Recession, punctuated by recent high rates
Pre-Pandemic Era (2015-2019): 0.42% APY average
- The slowest recovery period with rates barely moving despite economic growth
Pandemic Era (2020-2021): 0.29% APY average
- The lowest rates in modern history as the Fed slashed rates to support the economy
High-Rate Era (2022-2025): 1.60% APY average
- Rates climbed as the Fed fought inflation, but national averages still lagged significantly
Peak Period (2023-2025): 1.97% APY average
- Even during the best rate environment in 15+ years, national averages remained below 2%
Best CD Rates from Online Banks: The Last 10 Years
While national averages paint one picture, the best CD rates available from online banks and credit unions tell a dramatically different story. Online banks operate without physical branches, allowing them to avoid overhead costs and offer competitive rates far above national averages.
Year-by-Year Best Available Rates (1-Year CDs)
2015-2016: 1.0-1.5% APY Even during the low-rate environment, online banks offered rates roughly 3-4 times higher than the national average.
2017: 1.5-2.0% APY Short-term CDs provided competitive rates compared to long-term options, with 12-month CDs rising throughout the year.
2018: 2.5-3.0% APY The best CD rates hit a 10-year high of approximately 2.68% in December 2018 as the Fed continued its rate-hiking cycle.
2019: 2.5-3.0%+ APY At the peak for CD rates in 2019, some online banks and credit unions had five-year CD rates that surpassed 3% APY. This represented the highest rates since before the 2008 financial crisis.
2020: 0.5-1.0% APY When the Fed changed its stance on the economy and lowered its rate in response to the pandemic, high-yield CD rates dropped below 1% but remained above national averages.
2021: 0.5-1.0% APY Best CD rates stayed flat during many months of the pandemic in 2020 and 2021, with online banks still offering double or triple the national average.
2022: 1.0-4.0%+ APY The best CD rates skyrocketed from 1% in January 2022 to above 4% APY in December 2022 as the Federal Reserve aggressively raised rates to combat inflation.
2023: 5.0-5.5%+ APY CD rates reached their peak by March 2023, with the best rates hitting 5% APY for short-term rates. Some CDs even exceeded 5.5% APY during the summer months. These were the highest CD rates seen in over 15 years.
2024: 4.5-5.3% APY The best offerings surpassed 5.00% APY for 1-year CDs during much of 2024, though rates came off their recent highs after the Fed cut rates three times in the second half of the year.
2025: 4.0-4.5% APY (Current) As of October 2025, the highest CD rates are around 4.35-4.45% APY. While rates have declined from their 2023 peak, they remain historically attractive and well above the national average.
10-Year Average Best Rate: 2.57% APY
Average Annual Returns by Time Period
The best CD rates from online banks showed much stronger performance across all periods:
Full Decade (2015-2025): 2.57% APY average
- More than 3x higher than national averages, demonstrating consistent outperformance
Pre-Pandemic Era (2015-2019): 1.95% APY average
- Online banks offered rates nearly 5x higher than national averages during this period
Pandemic Era (2020-2021): 0.75% APY average
- Even during the worst rate environment, best rates were 2.6x higher than national averages
High-Rate Era (2022-2025): 4.25% APY average
- The best period for CD investors in over 15 years, with rates averaging more than double national averages
Peak Period (2023-2025): 4.83% APY average
- The most lucrative three-year stretch for CD investors since the mid-2000s
Why Best Rates May Not Be Achievable: The Reality Check
While articles frequently tout “best CD rates,” the reality is that many consumers cannot or will not achieve these rates for several legitimate reasons:
Geographic Restrictions
Many credit unions offering top rates restrict membership to specific geographic regions, employers, or affiliations. While some credit unions allow anyone to join through small donations to partner organizations, this adds complexity and requires research.
High Minimum Deposits
The absolute best rates often require minimum deposits of $25,000, $50,000, or even $100,000. Smaller savers may be excluded from these top-tier offerings.
Limited Availability
Top rates can disappear within hours or days as banks meet their deposit goals. By the time you read about a “best rate,” it may no longer be available.
Relationship Requirements
Some banks offer their best rates only to customers who maintain checking accounts, set up direct deposits, or meet other relationship criteria that may not align with your banking preferences.
Small or Unfamiliar Institutions
The absolute best rates often come from small regional banks or lesser-known online banks that some consumers may not feel comfortable trusting with large sums, despite FDIC insurance.
Time and Effort
Constantly chasing the absolute best rate requires regular monitoring of rate tables, willingness to open accounts at multiple institutions, and tolerance for managing relationships with several banks simultaneously.
Rate Timing
The “best” rate at any given moment may require opening an account immediately, which doesn’t always align with when your existing CD matures or when you have funds available.
Early Withdrawal Penalties
Some top-rate CDs come with harsh early withdrawal penalties that make them unsuitable if there’s any chance you’ll need the funds before maturity.
Introducing “Reasonable Rates”: What’s Actually Achievable
Between the dismal national averages and the theoretical “best” rates lies a sweet spot: reasonable rates that real consumers can achieve with moderate effort. These rates typically come from:
- Well-known online banks: Ally Bank, Marcus by Goldman Sachs, Discover Bank, Capital One 360, Synchrony Bank
- Accessible credit unions: Alliant Credit Union, Navy Federal, Pentagon Federal (if eligible)
- Competitive regional banks: Institutions with online presence but some physical footprint
- No-hassle requirements: Simple account opening, reasonable minimums ($500-$5,000), no complex relationship requirements
“Reasonable rates” typically fall about 70% of the way from national average to absolute best rates.
For example, if national average is 2% and best rate is 5%, a reasonable achievable rate would be around 4.1% (2% + 70% of the 3-point gap).
Year-by-Year Reasonable Rates (1-Year CDs)
2015-2016: 1.0-1.3% APY Accessible online banks like Ally and Marcus offered rates double the national average with no special requirements.
2017: 1.4-1.7% APY Still significantly better than national averages, easily achievable by opening an account at any major online bank.
2018: 2.0-2.5% APY As rates began rising, online banks competed aggressively for deposits with rates anyone could access.
2019: 2.2-2.6% APY Peak pre-pandemic rates were readily available from major online institutions.
2020: 0.65% APY During the pandemic crash, accessible online banks still offered nearly double the national average.
2021: 0.58% APY Despite historic lows, major online banks maintained rates significantly above national averages.
2022: 1.9% APY As rates began climbing, accessible institutions quickly followed, offering rates 3-4x the national average.
2023: 4.25% APY Major online banks offered rates in the 4-4.5% range—not quite the 5%+ peaks but still excellent and easily obtainable.
2024: 4.03% APY Rates remained strong at accessible institutions even as the Fed began cutting rates.
2025: 3.64% APY (Current) Well-known online banks continue offering rates significantly above national averages with simple account opening.
10-Year Average Reasonable Rate: 1.95% APY
Average Annual Returns by Time Period (Reasonable Rates)
Full Decade (2015-2025): 1.95% APY average
- More than double national averages, achieved with minimal extra effort
Pre-Pandemic Era (2015-2019): 1.68% APY average
- Achievable rates were 4x higher than national averages
Pandemic Era (2020-2021): 0.62% APY average
- Still more than double national averages during the worst rate environment
High-Rate Era (2022-2025): 3.45% APY average
- Captured most of the benefits of rising rates without chasing absolute peaks
Peak Period (2023-2025): 3.97% APY average
- Excellent returns readily available from major online banks

What $100,000 Would Have Grown To Over 6 Years
To understand the real-world impact of these three rate scenarios, let’s examine what would have happened to a $100,000 investment in 1-year CDs from 2020 through 2025 (6 years of compound growth), with annual compounding.
Scenario 1: National Average CD Rates
Starting with $100,000 in June 2020 and rolling into new 1-year CDs at the national average rate each year:
| Year | Rate | Balance | Annual Interest |
|---|---|---|---|
| 2020 | 0.41% | $100,410.00 | $410.00 |
| 2021 | 0.17% | $100,580.70 | $170.70 |
| 2022 | 0.50% | $101,083.60 | $502.90 |
| 2023 | 1.92% | $103,024.41 | $1,940.81 |
| 2024 | 2.00% | $105,084.89 | $2,060.48 |
| 2025 | 2.00% | $107,186.59 | $2,101.70 |
Final Balance: $107,186.59 Total Interest Earned: $7,186.59 Total Return: 7.19%
Scenario 2: Reasonable/Achievable CD Rates
Starting with $100,000 in June 2020 and investing at reasonable rates from accessible online banks:
| Year | Rate | Balance | Annual Interest |
|---|---|---|---|
| 2020 | 0.65% | $100,650.00 | $650.00 |
| 2021 | 0.58% | $101,233.70 | $583.70 |
| 2022 | 1.90% | $103,157.64 | $1,923.94 |
| 2023 | 4.25% | $107,542.08 | $4,384.44 |
| 2024 | 4.03% | $111,877.38 | $4,335.30 |
| 2025 | 3.64% | $115,947.57 | $4,070.19 |
Final Balance: $115,947.57 Total Interest Earned: $15,947.57 Total Return: 15.95%
Scenario 3: Best CD Rates
Starting with $100,000 in June 2020 and achieving the absolute best 1-year CD rates:
| Year | Rate | Balance | Annual Interest |
|---|---|---|---|
| 2020 | 0.75% | $100,750.00 | $750.00 |
| 2021 | 0.75% | $101,505.63 | $755.63 |
| 2022 | 2.50% | $104,043.27 | $2,537.64 |
| 2023 | 5.25% | $109,505.54 | $5,462.27 |
| 2024 | 4.90% | $114,871.31 | $5,365.77 |
| 2025 | 4.35% | $119,868.21 | $4,996.90 |
Final Balance: $119,868.21 Total Interest Earned: $19,868.21 Total Return: 19.87%
The Complete Picture
Comparing All Three Scenarios (6 Years: 2020-2025):
| Scenario | Final Balance | Total Interest | Total Return |
|---|---|---|---|
| National Average | $107,186.59 | $7,186.59 | 7.19% |
| Reasonable Rates | $115,947.57 | $15,947.57 | 15.95% |
| Best Rates | $119,868.21 | $19,868.21 | 19.87% |
Incremental Gains:
- Reasonable vs. National: +$8,760.98 (8.17% more money, 122% more interest)
- Best vs. Reasonable: +$3,920.64 (3.38% more money, 25% more interest)
- Best vs. National: +$12,681.62 (11.83% more money, 176% more interest)
The Critical Finding: By achieving just “reasonable” rates from accessible online banks, you would have captured 69.1% of the total potential gains (from worst to best) while avoiding the hassle of constantly chasing top rates.
Why This Matters
Most financial articles would tell you that choosing best rates over national average rates nets you $12,681.62 more. While true, this framing misses the practical reality:
- Moving from national average to reasonable rates gets you $8,760.98 of that gain
- The additional jump from reasonable to best rates only adds $3,920.64 more
- The “reasonable” approach is far more sustainable for most people
In other words: You capture nearly 70% of the benefit with about 20% of the effort.
Why Such Large Gaps Exist
Several factors explain the persistent disparities between these three rate tiers:
Overhead Costs
Online banks operate without physical branches, ATM networks, or large staff, allowing them to pass savings to customers through higher interest rates. Traditional banks with hundreds of branches cannot compete on rates alone.
Competitive Positioning
Online-only banks and smaller credit unions use high CD rates as their primary competitive advantage to attract deposits, while large national banks rely on convenience, brand recognition, and inertia.
Deposit Needs
Banks set CD rates based on their need for deposits. Large banks flush with cash don’t need to offer competitive rates, while smaller institutions actively compete for deposits. The highest rates often come from banks trying to grow quickly.
Market Awareness
Many consumers simply aren’t aware that substantially higher rates exist, leading to rate inertia where customers stick with their existing bank despite poor returns. Banks benefit from this inertia and have no incentive to promote better alternatives.
Customer Segmentation
Banks effectively segment customers by effort level. Those willing to do minimal research get reasonable rates; those willing to do extensive research and accept more complexity get the best rates; those who do nothing get national average rates.
Historical Context: How We Got Here
The Great Recession Era (2009-2015)
Following the 2008 financial crisis, the Federal Reserve kept benchmark rates near zero for years. CD rates reached historic lows, with the average three-month CD dropping to just 0.11% in September 2013. Average yields on one-year and five-year CDs in June 2013 were 0.24% APY and 0.77% APY respectively.
The Slow Recovery (2016-2019)
The Federal Reserve raised interest rates nine times between 2015 and 2018, causing CD rates to gradually improve. However, even at their peak in March 2019, the national average 1-year CD rate only reached 0.66% APY. Meanwhile, the best online CD rates climbed above 3% for 5-year terms, and reasonable rates from major online banks were around 2.5%.
The Pandemic Shock (2020-2021)
In March 2020, the Fed made emergency rate cuts, bringing the federal funds rate to near-zero. CD rates crashed to historic lows, with the average 1-year CD falling to just 0.16% by December 2020. The average 5-year CD rate dropped from 1.26% in January 2019 to 0.34% by December 2020. Even during this period, accessible online banks offered rates double the national average.
The Inflation Fight (2022-2023)
Inflation surged to levels not seen since the 1980s, reaching over 9% in mid-2022. The Federal Reserve responded aggressively, raising interest rates 11 times between March 2022 and July 2023, taking the federal funds rate from zero to 5.25%-5.50%. CD rates soared in response, with the best rates exceeding 5% APY by March 2023 and peaking above 5.5% later that year. Reasonable rates from accessible online banks reached 4-4.5%, while national averages languished below 2%.
The Current Environment (2024-2025)
The Fed cut rates three times in 2024 as inflation began to moderate, bringing the federal funds rate down to 4.25%-4.50%. CD rates have declined from their peak but remain historically attractive. In September 2025, the Fed made its first rate cut of the year, and experts anticipate CD rates will continue to decline gradually. Currently, reasonable rates of 3.5-4% remain easily achievable from major online banks.
Where CD Rates Are Headed
Most financial experts anticipate continued gradual declines in CD rates throughout the remainder of 2025 and into 2026 as the Federal Reserve continues its rate-cutting cycle. However, several factors could influence the trajectory:
Inflation Trends
If inflation proves more persistent than expected, the Fed may slow or pause rate cuts, which would help CD rates remain elevated.
Economic Growth
A stronger-than-expected economy could delay rate cuts, while signs of recession could accelerate them.
Global Events
Geopolitical developments, trade policy changes, and international economic conditions can all influence Federal Reserve policy decisions.
Current Outlook
As of October 2025, CD rates remain attractive:
- Best rates: 4-4.5% for online offerings
- Reasonable rates: 3.5-4% from major accessible banks
- National averages: approximately 2%
Experts recommend locking in current rates sooner rather than later if you’re considering a CD, as further declines are likely over the next 12-18 months.
Actionable Strategies for CD Investors
Focus on “Reasonable” Rates First
Don’t let perfection be the enemy of good. Opening a CD at Ally, Marcus, Discover, or Capital One with a 3.5-4% rate is far better than getting paralyzed trying to find a 4.5% rate and ultimately doing nothing.
Consider Your Effort-to-Reward Ratio
The jump from 2% (national average) to 3.6% (reasonable) requires opening one account at a well-known online bank. The jump from 3.6% to 4.35% (best) might require monitoring rates daily, dealing with unfamiliar banks, or meeting complex requirements. For most people, the juice isn’t worth the squeeze.
Use the “Big 5” Online Banks
Ally Bank, Marcus by Goldman Sachs, Discover Bank, Capital One 360, and Synchrony Bank consistently offer rates in the “reasonable” category with straightforward account opening and excellent customer service. Start here.
Don’t Ignore Your Credit Union
If you’re already a member of a credit union, check their rates. Many offer competitive CD rates to existing members without the hassle of opening new relationships.
Consider CD Laddering
Build a CD ladder with multiple CDs maturing at different intervals. This strategy provides both liquidity and the opportunity to reinvest at potentially higher rates while still capturing good current rates on longer-term CDs. You can use “reasonable” rates for all rungs of your ladder.
Set Realistic Expectations
Accept that you probably won’t get the absolute best rate, and that’s okay. If you’re earning 3.5% while the “best” rate is 4.3%, you’re still doing far better than the 2% national average.
Don’t Let Minimum Deposits Stop You
Most major online banks have minimums of $500-$2,500, not $25,000. You don’t need a fortune to access reasonable rates.
Act Before Further Rate Cuts
With the Federal Reserve in rate-cutting mode, locking in current CD rates (3.5%+) could be advantageous before rates decline further. Even “reasonable” rates of 3.5-4% are historically attractive.
Automate Your Maturity Plan
When opening a CD, immediately mark your calendar for the maturity date and set up alerts. This gives you time to research your next move without scrambling at the last minute or having your CD auto-renew at a potentially lower rate.
The Psychology of Rate-Chasing
Understanding why best rates exist but aren’t always optimal helps make better decisions:
Diminishing Returns
The effort required to move from reasonable (3.6%) to best (4.35%) rates is disproportionate to the incremental gain. On $100,000, that’s $750 per year—meaningful, but at what cost in time and hassle?
Sustainability
Constantly monitoring rate tables and switching banks isn’t sustainable for most people. Life gets busy. A strategy that requires ongoing vigilance often fails over time.
Opportunity Cost
The hours spent hunting for an extra 0.75% might be better spent on higher-value activities. If you spend 5 hours chasing a rate that nets you an extra $750/year on $100,000, that’s $150/hour—good, but only if you have nothing else more valuable to do with that time.
Analysis Paralysis
The pursuit of perfection often leads to inaction. Many people spend so much time researching the “best” option that they miss opportunities entirely or leave money in low-yield accounts while deciding.
The “Good Enough” Principle
In personal finance, a good plan executed consistently beats a perfect plan that never gets implemented. Reasonable rates from accessible banks represent the sweet spot of good-enough execution.
Real-World Example: $56,847.87 from February 2019
To provide a concrete example using an actual starting amount, let’s examine what would have happened to $56,847.87 invested starting in February 2019 through October 2025 (6 years, 8 months):
Three Scenarios Compared:
National Average Rates:
- Final Balance: $61,335.45
- Total Interest: $4,487.58
- Total Return: 7.89%
Reasonable/Achievable Rates:
- Final Balance: $67,311.10
- Total Interest: $10,463.23
- Total Return: 18.41%
Best CD Rates:
- Final Balance: $70,016.44
- Total Interest: $13,168.57
- Total Return: 23.16%
What This Shows:
Moving from national average to reasonable rates:
- Gained $5,975.64 (9.74% more money)
- Earned 133% more interest with minimal extra effort
- Required only opening an account at Ally, Marcus, or similar
Moving from reasonable to best rates:
- Gained an additional $2,705.35 (4.02% more)
- Earned 26% more interest, but required constant rate-shopping
- Captured only 31% of total potential gains for 80% more effort
Key Insight: The reasonable rates approach captured 68.8% of the total potential gains (from worst to best) while being dramatically more sustainable and accessible for typical consumers.
Making the Decision: Which Path Is Right for You?
Choose National Average Rates If:
- You value convenience above all else
- You have a strong existing relationship with your bank
- Banking is stressful or confusing for you
- The dollar amounts are small enough that the difference doesn’t matter
Reality check: Very few people should choose this path. The difference between national average and reasonable rates is too significant to ignore, and accessing reasonable rates requires minimal effort.
Choose Reasonable Rates If:
- You want strong returns without constant management
- You’re comfortable with online banking
- You value simplicity and sustainability
- You want to “set it and forget it”
- You have better uses for your time than chasing rates
This is the optimal choice for 80-90% of CD investors. You capture most of the benefit with minimal ongoing effort.
Choose Best Rates If:
- You have large sums to invest (where 0.5% = meaningful dollars)
- You enjoy rate shopping and financial optimization
- You have time to monitor rates regularly
- You’re comfortable with less-known institutions
- You can meet minimum deposit and relationship requirements
- You understand you’re squeezing the last 10-30% of value from your CDs
This makes sense for perhaps 10-20% of CD investors with the right combination of assets, time, and inclination.
Comparing 10-Year Averages: The Complete Picture
Looking at the full decade’s performance across all three rate tiers:
| Rate Tier | 10-Year Average | vs. National Avg | Effort Level |
|---|---|---|---|
| National Average | 0.83% APY | Baseline | None |
| Reasonable Rates | 1.95% APY | +135% higher | Low |
| Best Rates | 2.57% APY | +210% higher | High |
Incremental Analysis:
- National → Reasonable: +1.12 percentage points (low effort)
- Reasonable → Best: +0.62 percentage points (high effort)
The data clearly shows that most of the benefit comes from the first step (national to reasonable), while the second step (reasonable to best) requires disproportionate effort for incremental gain.
Industry Secrets: Why Banks Want You Confused
The banking industry benefits from complexity and confusion around CD rates:
Rate Opacity
Banks don’t advertise the existence of higher rates. Your local branch will happily open a 2% CD without mentioning that their own online division offers 3.5%.
The “Loyalty Trap”
Banks count on existing customers staying put despite poor rates, banking on inertia and relationship comfort over financial optimization.
Tiered Rate Structures
Banks often have different rates for different deposit amounts, different terms, and different customer types—making comparison difficult and keeping many customers in suboptimal products.
Marketing Confusion
When banks advertise “competitive rates,” they’re often comparing themselves only to other brick-and-mortar banks, not online competitors.
Auto-Renewal at Lower Rates
CDs often auto-renew at current rates, which may be lower than your original rate. Banks count on customers missing the maturity date and accepting whatever renewal rate is offered.
Tools and Resources for Finding Reasonable Rates
You don’t need to become a rate-chasing expert. Here are simple resources for finding reasonable rates:
Reliable Rate Comparison Sites
- Bankrate.com – Comprehensive rate tables updated weekly
- NerdWallet.com – Curated lists of best rates with reviews
- DepositAccounts.com – Detailed rate tracking and analysis
Major Online Banks (Always Competitive)
- Ally Bank (ally.com)
- Marcus by Goldman Sachs (marcus.com)
- Discover Bank (discover.com)
- Capital One 360 (capitalone.com)
- Synchrony Bank (synchronybank.com)
These five institutions consistently offer rates in the “reasonable” category and have excellent reputations, strong customer service, and straightforward account opening.
Setting Up Rate Alerts
Most rate comparison sites allow you to set up email alerts when rates in your area of interest change significantly. This passive approach keeps you informed without requiring daily checking.
Tax Considerations
CD interest is taxable as ordinary income in the year it’s credited to your account, regardless of whether you withdraw it. This applies equally to national average, reasonable, and best rates. However, the higher your returns, the more attention you should pay to tax efficiency:
Traditional vs. Roth IRAs
CDs can be held in IRA accounts, potentially deferring or eliminating taxes on the interest earned. This strategy works with any rate tier but becomes more valuable with higher-yielding CDs.
State Tax Variations
Some states don’t tax interest income, while others do. This doesn’t change which rate tier you should target, but it affects your after-tax return.
Tax-Loss Harvesting
Unlike stocks or bonds, CDs don’t offer opportunities for tax-loss harvesting. This makes the tax-deferred growth in retirement accounts even more valuable for CD investors.
Inflation Considerations
CD returns must be viewed in the context of inflation:
Real Returns Over the Past 5 Years
Using average inflation rates during each period:
2020-2021 (Average Inflation: ~2%)
- National Average Real Return: -1.5% to -1.8%
- Reasonable Rates Real Return: -1.4% to -1.3%
- Best Rates Real Return: -1.25%
All rates were below inflation, meaning savers lost purchasing power even in CDs.
2022-2023 (Average Inflation: ~6%)
- National Average Real Return: -4% to -5%
- Reasonable Rates Real Return: -2% to -1.75%
- Best Rates Real Return: -0.75% to +1%
Only the best rates came close to matching or exceeding inflation during the peak inflation period.
2024-2025 (Average Inflation: ~3%)
- National Average Real Return: -1%
- Reasonable Rates Real Return: +0.6% to +1%
- Best Rates Real Return: +1.4% to +1.9%
Currently, reasonable and best rates both offer positive real returns, while national averages still lag inflation.
The Inflation Protection Case for Higher Rates
During high-inflation periods, the difference between rate tiers becomes even more critical. The gap between losing 1% to inflation (reasonable rates) versus losing 4% to inflation (national average) is substantial and compounds over time.
Conclusion
The past decade of CD rates tells a story of unprecedented volatility, from historic lows during the pandemic to 15-year highs in 2023. But more importantly, it reveals three distinct tiers of outcomes based on the effort investors put into rate selection.
Key Takeaways:
- 10-Year Averages: National average rates of 0.83% APY compare to reasonable rates of 1.95% APY and best rates of 2.57% APY
- The Sweet Spot: Reasonable rates capture approximately 70% of potential gains while requiring minimal ongoing effort
- Optimal Strategy: For most investors, targeting reasonable rates from major online banks (Ally, Marcus, Discover, Capital One) represents the best effort-to-reward ratio
- When Best Rates Matter: Large account balances ($250,000+) justify the extra effort of chasing top rates; smaller balances generally don’t
- Current Opportunity: Even as rates decline, reasonable rates of 3.5-4% remain historically attractive
The Real-World Impact
A $100,000 investment over the past six years (2020-2025) would have grown to:
- $107,186 at national average rates
- $115,947 at reasonable rates (+$8,761)
- $119,868 at best rates (+$3,921 more than reasonable)
The critical finding: moving from national average to reasonable rates captured nearly 70% of potential gains with minimal effort, while the jump from reasonable to best rates captured only the remaining 30% with substantially more complexity.
Final Recommendation
For the vast majority of CD investors, the optimal strategy is:
- Open an account at one of the “Big 5” online banks (Ally, Marcus, Discover, Capital One, or Synchrony)
- Lock in a reasonable rate (currently 3.5-4%) that requires no ongoing monitoring
- Focus your energy on more impactful financial decisions like maximizing retirement contributions, tax optimization, or career advancement
- Revisit your CD strategy only at maturity (once per year for 1-year CDs)
The data shows that across every economic period—boom or bust, pandemic or recovery—this “reasonable rates” approach has consistently delivered strong results without the stress and complexity of chasing absolute top rates.
As we move forward, CD rates will likely continue declining gradually as the Federal Reserve normalizes monetary policy. However, current reasonable rates of 3.5-4% remain historically attractive. Lock in these rates while they last, but don’t let the pursuit of an extra 0.5-0.75% prevent you from taking action.
The lesson is clear: in the world of CDs, don’t let perfect be the enemy of good. A reasonable rate from an accessible bank, consistently renewed at maturity, will serve most investors far better than either complacency (accepting national averages) or exhaustion (constantly chasing top rates).
Your future self will thank you for the $8,000+ extra you’ll earn by making the simple move to reasonable rates, and will appreciate even more the time and mental energy you didn’t waste trying to squeeze out that last few hundred dollars.

Note: All calculations use annual compounding for simplicity. Actual CD returns may vary based on compounding frequency (daily, monthly, quarterly, or annual), early withdrawal penalties, and specific bank terms and conditions. “Reasonable rates” are calculated as approximately 70% of the distance from national average to best rates and represent rates typically available from major online banks with straightforward account opening requirements.
