What Is a Compound Interest Calculator?
A compound interest calculator is a simple but powerful financial tool that computes how money grows when interest accumulates on both the initial amount and previously added interest. Unlike simple interest, compounding allows your money to accelerate over time, making it especially valuable for long-term savings, investing, and financial planning.
The calculator shown above includes fields for principal amount, annual interest rate, time in years, and compounding frequency. After inputs are entered, a single click reveals the estimated future value.
How to Use the Compound Interest Calculator Online
