Compound interest is calculated using A = P(1 + r/n)^(nt), where P is the principal, r is the annual rate, n is the number of times compounded per year, and t is the time in years. Example: $1,000 at 5% compounded monthly for 3 years: A = 1000(1 + 0.05/12)^(12×3) = 1000(1.00417)^36 ≈$ 1,161.62. The key difference from simple interest (I = Prt) is that compound interest earns interest ON interest.
