See how your money grows with compound interest. Enter your initial investment, monthly contributions, interest rate, and time period to see your projected balance.
Compound interest is interest calculated on both your initial principal and the accumulated interest from previous periods. This "interest on interest" effect helps your money grow exponentially over time. Our calculator uses the formula: A = P(1 + r/n)^(nt) + PMT × (((1 + r/n)^(nt) - 1) / (r/n)), where P is principal, r is annual rate, n is compounding frequency, t is years, and PMT is monthly contribution.
