How to calculate annual percentage yield from monthly rate
This calculator converts a monthly interest rate into its equivalent Annual Percentage Yield (APY), accounting for the effect of monthly compounding over a full year.
How the calculation works
APY = ((1 + Monthly rate/100)^Months per year − 1) × 100.
Example
A 0.5% monthly rate compounded over 12 months: APY = ((1+0.005)^12 − 1) × 100 ≈ 6.17%.
