# Compound interest calculator

Show the final amount and interest earned for a principal at weekly, monthly, quarterly, half-yearly, or yearly compounding frequencies.

Enter a principal, rate, and term to compound it.

This is the standard A = P × (1 + r/n)^(n·t) with nothing else priced in: no deposits along the way, no tax, no fees, no inflation adjustment, and no year-by-year schedule. The rate is treated as nominal, so the effective annual rate shown is what the chosen frequency actually delivers. Figures are bare numbers; pick your own currency.
