Enter the total price ($) and the interest rate (%) into the Interest Cost Calculator. The calculator will evaluate and display the Interest Cost. 

Interest Cost Formula

The following formula is used to calculate the Interest Cost. 

IC = TP * IR/100
  • Where IC is the Interest Cost ($)
  • TP is the total price ($) 
  • IR is the interest rate (%) 

To calculate the interest cost, multiply the total price by the interest rate.

How to Calculate Interest Cost?

Example Problem #1:

  1. First, determine the total price ($). The total price ($) is given as 500.
  2. Next, determine the interest rate (%). The interest rate (%) is provided as 20.
  3. Finally, calculate the Interest Cost using the equation above: 

IC = TP * IR/100

The values given above are inserted into the equation below:

Can the Interest Cost Calculator be used for both simple and compound interest calculations?

The Interest Cost Calculator, as described, is designed for simple interest calculations, where interest is calculated only on the principal amount. For compound interest, where interest is calculated on the principal and also on accumulated interest, a different formula and calculator would be needed.
