Interest
Enter principal, annual rate, years, and an optional recurring contribution (per month or per year). The future value uses A = P(1 + r/n)^(nt) for the lump sum, plus the annuity-future-value formula for recurring contributions at the matching period rate; n is the compounding frequency per year. Interest = future value − total invested. The table shows year-by-year contributed amount, ending balance and interest earned. All math runs in your browser.
