≈% APY Calculator
How It Works
Calculate annual percentage yield from a nominal interest rate and compounding frequency. Use APY Calculator to explore how the main financial inputs change the payment, cost, return, or cash-flow result before making a decision.
The result is most useful when the inputs match the definitions used by this calculator. For this tool, the underlying method is: APY = (1 + r/n)^n − 1. Compare the output with the worked example, then change one meaningful input at a time to see how the result responds.
Understanding APY
APY is a financial calculation that uses the inputs shown above to estimate a payment, amount, rate, return, cost, or planning value. Financial calculations depend on assumptions and may not include every fee, tax, market change, or contractual term. Review the apy inputs and units before relying on the result.
When to Use This Calculator
Use APY Calculator to explore how the main financial inputs change the payment, cost, return, or cash-flow result before making a decision.
Practical tip: For this APY Calculator, change one financial assumption at a time—such as the rate, amount, contribution, fee, or tenure shown in the inputs—so you can see which factor drives the result.
Formula
APY = (1 + r/n)^n − 1
Example
A 5% rate compounded monthly has an APY slightly above 5%.
