The difference between daily and annual compounding on $10,000 over 1 year is $12.67. Over longer terms, the difference grows substantially.
CD Ladder 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: Split $10,000 into 5 CDs: 1-Year, 2-Year, 3-Year, 4-Year, 5-Year. Every year one CD matures. Reinvest at the longest term (5 years) to maintain the ladder. This strategy yields an average rate of approximately 4.73% while maintaining annual liquidity on 20% of your funds.
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. A 5.00% interest rate compounded monthly = 5.12% APY. Always compare CDs using APY.
