Contributions matter

Compound Interest Formula

FV = P × (1 + r/n)^(nt) + PMT × ((1 + r/n)^(nt) – 1) / (r/n) × (1 + r/n)^(t if beginning)

Where: P = principal, r = annual rate, n = compounds per year, t = years, PMT = regular contribution per period. Our calculator handles daily compounding and flexible contribution schedules.
