How Compound Interest Calculator works

Calculate compound growth, total contributions and earned interest with annual, quarterly, monthly or daily compounding.

The formula

A = P(1 + r/n)^(nt). Optional monthly contributions are added at the end of each month using the equivalent monthly rate.

A practical example

₹1,00,000 at 10% compounded annually for 5 years grows to about ₹1,61,051 before additional contributions.
