The Power of CD Compounding Frequency
Compounding frequency determines how often the interest you earn is added back to your principal balance. The more frequently interest compounds, the faster your savings grow, because you earn 'interest on interest'.
Most modern high-yield CDs compound interest daily and credit it to your account monthly. However, some traditional banks still compound monthly, quarterly, or annually. Our CD Compound Interest Calculator allows you to see the exact financial difference between these compounding frequencies so you can choose the best CD product.
Compounding Frequency Yield Comparison
Here is how a $10,000 deposit at a 5.00% APR nominal interest rate grows over a 5-year term under different compounding frequencies:
- Daily Compounding (365/year): Yields $12,840.03 ($2,840.03 interest earned, effective APY: 5.13%).
- Monthly Compounding (12/year): Yields $12,833.59 ($2,833.59 interest earned, effective APY: 5.12%).
- Quarterly Compounding (4/year): Yields $12,820.37 ($2,820.37 interest earned, effective APY: 5.09%).
- Annual Compounding (1/year): Yields $12,762.82 ($2,762.82 interest earned, effective APY: 5.00%).
Daily compounding earns you $77.21 more than annual compounding for the same interest rate. The difference grows even larger with higher deposit amounts and longer terms.
