Compound Interest in Maths

Last Updated : 21 Aug, 2025

Compound interest is the money you earn on your original amount, plus the interest that has already been added to it. This means you earn interest on your interest, and over time, your money grows faster.

How It Works:

  1. Starting Point (Principal): You start with an amount of money, called the principal.
  2. Interest is Added: After some time, interest is added to that principal.
  3. Next Round: In the next time period, you earn interest not only on your original money but also on the interest that was added before.
