About Compound Interest
Compound interest is interest calculated on the initial principal and the accumulated interest from previous periods. Unlike simple interest, compound interest allows your investment to grow exponentially over time, making it a powerful tool for long-term wealth building.
Formula
A = P(1 + r/n)^(nt)
Where: A = Final amount, P = Principal, r = Annual interest rate, n = Compounding frequency, t = Time in years
