What is Compound Interest?
Compound interest is interest calculated on both the initial principal and the accumulated interest from previous periods. Unlike simple interest, compound interest grows exponentially over time — this is why Albert Einstein reportedly called it the "eighth wonder of the world."
Compound Interest Formula
A = P(1 + r/n)^(nt)
Where: A = Final amount, P = Principal, r = Annual interest rate, n = Compounding frequency per year, t = Time in years
