About the Interest Calculator

This calculator helps you compute interest on a principal amount using two different methods: simple interest and compound interest.

How it Works

  • Simple Interest: Calculated only on the initial principal amount.
  • Compound Interest: Calculated on the initial principal and also on the accumulated interest from previous periods. You can choose how frequently the interest is compounded (e.g., annually, monthly).

Key Inputs

  • Principal Amount: The initial amount of money.
  • Annual Interest Rate: The rate at which the money grows per year.
  • Time Period: The duration for which the interest is calculated.

Use the tabs to switch between simple and compound interest to see how they affect your returns over time.
