About Interest Calculations

Interest is a charge for the privilege of borrowing money, typically expressed as an annual percentage rate (APR). There are two main types of interest:

Simple Interest: Calculated only on the principal amount, or on that portion of the principal amount which remains unpaid.
Compound Interest: Calculated on the initial principal, which also includes all of the accumulated interest from previous periods.

Using this calculator, you can quickly determine how much interest will accrue over time, depending on the type of interest you choose. For more detailed information, you can check out Wikipedia – Interest.
