Compound Interest Calculator

Albert Einstein once called compound interest the “eighth wonder of the world”. He who understands it, earns it; he who doesn’t, pays it.

This calculator helps you visualize how small, regular contributions can grow into a significant fortune over time due to the power of accumulated interest.

🧮 Investment Growth Calculator

How to use this tool?

  • Initial Investment: The amount of money you are starting with today.
  • Monthly Contribution: How much you can add to your account every month.
  • Interest Rate: The expected annual return (e.g., the S&P 500 averages ~10%).
  • Years to Grow: How long you plan to keep the money invested.

Why start early?

Time is your biggest asset. Due to exponential growth, investing $500/month for 30 years yields significantly more than investing $1,000/month for 15 years. Use the calculator above to verify this math!
