About this compound interest calculator
This free compound interest calculator shows how your money can grow over time. Enter a starting amount, an annual interest rate, the number of years, and how often interest compounds. You can also add an optional monthly contribution to see how regular saving accelerates growth. The result shows your projected future value, how much you contributed, and how much is interest earned.
Compound interest means you earn interest on your interest, which is why long-term saving and investing can grow faster than many people expect. Switch the currency to match your country, and experiment with different rates and timeframes to plan your goals.
How to use it
Fill in the starting amount, rate, and years, choose a compounding frequency, and optionally add a monthly contribution. The projection updates instantly.
