How It Works
Final balance = principal grown by compound interest + future value of all monthly contributions.
Compound interest formula: A = P × (1 + r/n)n×t, where P = principal, r = annual rate, n = compounding periods per year, t = years.
Monthly contributions use the future value of an annuity: PMT × [((1 + i)m − 1) ÷ i], where i = periodic rate, m = number of periods.
Interest earned = Final balance − Total contributions.
