Compound interest calculator

Compounding is what happens when your investment returns start earning their own returns. Instead of just your original money growing, the profits you've already made also grow — so your wealth builds faster over time. Use this calculator to see how regular contributions and compound interest could grow your investments, based on how much you plan to invest and the average return rate.

How does compound interest work?

Compound interest is often called the eighth wonder of the world. When you invest money, you earn returns. With compounding, those returns get reinvested and start earning returns of their own. Over time, this creates a snowball effect — your money grows faster and faster. The earlier you start and the more consistently you invest, the more powerful compounding becomes. Even small, regular contributions can grow into significant wealth over 20 or 30 years.
