Compound Interest Calculator

Compound interest is what happens when your money earns returns...and then those returns start earning returns too. It's the single most powerful force in long-term wealth building, and the earlier you start, the more dramatic the effect. Use this calculator to see how consistent contributions and time can turn modest savings into serious money.

This calculator assumes interest compounds monthly. Real-world returns vary — use this as a directional tool, not a guarantee. Read the newsletter for deeper context on how to think about investing and compound growth.
