Compounding and Your Return Calculator
This calculator demonstrates how compounding can affect your savings.
How the compounding and your return calculator works
It grows the same principal at the same nominal rate but with different compounding frequencies — annual through daily — and shows how each frequency raises your effective annual yield and final balance.
Worked example: with amount invested of $10,000, nominal annual rate of 6.00% and years of 10, the compounding and your return calculator shows extra from daily vs annual compounding of $312.
- Annual compounding
- $17,908
- Monthly compounding
- $18,194
- Daily compounding
- $18,220
- Daily effective APY
- 6.18%
The formula
Value = principal × (1 + rate ÷ n)^(n × years); effective APY = (1 + rate ÷ n)ⁿ − 1, where n is the compounding periods per year.

Questions about the compounding and your return calculator
Does more frequent compounding earn more?
Yes, but with diminishing returns. Moving from annual to monthly compounding makes a clear difference; from monthly to daily, much less.
What is the difference between rate and APY?
The nominal rate ignores compounding; the APY (annual percentage yield) folds it in. APY is the figure to compare when shopping for savings products.
Why do banks quote APY?
Because APY reflects what you actually earn after compounding, it is both more accurate and required for fair comparison between accounts.
