Compound interest calculator

Compound interest grows quietly, but over decades its effect can be dramatic. This calculator helps you visualize how consistent contributions, combined with time, can turn modest savings into substantial wealth.

Enter your starting amount, monthly contribution, expected return, and time horizon to see how small changes today can lead to very different outcomes tomorrow. Markets are unpredictable and past performance doesn't guarantee future results — but this tool can help build intuition for why long-term investors emphasize starting early and staying consistent.
