Guide

How this calculator works

Daily compounding means interest is calculated and added using 365 compounding periods per year. The difference versus monthly compounding is often small for normal savings rates, but it can matter over long periods or at higher rates.

You can still change every input: currency, interest rate, years and months, compounding frequency, contribution timing, inflation and tax or fees. Use the share URL button to save a pre-filled version of the result.
