📊 What is the Compound Interest Calculator and How Does It Work?
Compound interest earns returns on both principal and accumulated interest from previous periods. Unlike simple interest, this creates exponential growth — the longer you invest, the more powerful the effect becomes.
Formula
A = P × (1 + r/n)^(n×t) | P = principal, r = annual rate, n = compounds per year, t = years🪓 Step-by-Step: How to Use This Calculator

❓ Frequently Asked Questions

More frequent means more returns. Daily greater than monthly greater than quarterly. Most Indian instruments compound quarterly.

FDs, RDs, PPF, NPS, mutual funds, and bonds all effectively compound returns.
