Conversion Formula

routput = noutput × [(1 + rinput/ninput)ninput/noutput - 1]

where r = rate, n = periods per year

Note: This calculator converts between different compound interest frequencies. APY (Annual Percentage Yield) represents the actual yearly return including compounding.

APR vs APY: APR (Annual Percentage Rate) is the simple interest rate, while APY includes the effect of compounding.

Continuous Compounding: Represents the mathematical limit of compound interest using Euler's constant (e ≈ 2.71828).
