2026 CD Rate Trends and Best Rates (May 2026)
How Compounding Frequency Affects Your CD Earnings
More frequent compounding = higher earnings. For a $10,000 1-year CD at 5.00%: Annual compounding: $10,500.00 → $500 interest. Semi-Annual: $10,506.25 → $506.25 interest. Quarterly: $10,509.45 → $509.45 interest. Monthly: $10,511.62 → $511.62 interest. Daily: $10,512.67 → $512.67 interest. The difference between daily and annual compounding on $10,000 over 1 year at 5% is $12.67. Over longer terms, the difference grows substantially. Our calculator lets you compare all compounding options.

How to Build a CD Ladder (2026 Strategy)
A CD ladder spreads your investment across multiple CDs with different maturity dates, providing regular access to funds while earning higher long-term rates. Example for $10,000: $2,000 in 1-Year CD at 5.00%, $2,000 in 2-Year CD at 4.85%, $2,000 in 3-Year CD at 4.70%, $2,000 in 4-Year CD at 4.60%, $2,000 in 5-Year CD at 4.50%. Every year one CD matures. Reinvest at the longest term (5 years) to maintain the ladder and capture the highest rates. This strategy yields an average rate of approximately 4.73% while maintaining annual liquidity on 20% of your funds.
Understanding APY vs. Interest Rate
The interest rate is the base rate paid on your deposit. APY (Annual Percentage Yield) includes the effects of compounding and represents the true annual return. For example, a 5.00% interest rate compounded monthly = 5.12% APY. Always compare CDs using APY, not the interest rate, because APY accounts for how often the bank compounds interest. Banks may advertise higher interest rates that compound less frequently, resulting in lower actual returns. Our calculator automatically shows both the interest rate you entered and the calculated APY.
