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.
