Calculateur de APY

Calculate annual percentage yield from nominal rate and compounding periods.

Formula and method

This calculator computes APY directly in your browser without sending data to an external server.

Mathematical formula

  • APY: (1+rate ÷ 100 ÷ periods^(periods)-1) × 100

Variables and parameters

  • Nominal rate (rate): default value 5 %.
  • Compounds per year (periods): default value 12.

Some formulas are undefined for certain input combinations (such as division by zero or logarithms of non-positive numbers). In those cases the live tool displays an alert instead of NaN.
