About Compound Interest

Compound vs Simple Interest

Simple interest calculates interest only on the principal. Compound interest calculates interest on both the principal AND previously earned interest — making it grow exponentially. This is why Einstein reportedly called compound interest the "eighth wonder of the world".

How compounding frequency affects returns

More frequent compounding = higher effective yield

Daily compounding slightly beats monthly compounding

Indian bank FDs usually compound quarterly

PPF compounds annually; EPF compounds monthly

Formula used

A = P × (1 + r/n)^(n×t) where P = Principal, r = Annual rate, n = Compounding frequency per year, t = Time in years. The interest earned = A - P.
