Enter the current sale price and the percent off of the original price to calculate the original price of a good.

Original Price Formula

The following equation is used to calculate the original price of a good on discount.

OP = SP / (1-%/100)

  • Where OP is the original price ($)
  • SP is the current sale price ($)
  • % is the total percent off

Original Price Definition

An original price is defined as the original price an object is sold at before a discount is applied.

Original Price Example

The following is an example of how to calculate the original price of a discounted item.

  1. First, determine the sale price. This is usually the price found on the sticker. For this example, we will say 50$ is the sale price.
  2. Next, determine the percent off. For this example, we will assume a discounted rate of 25%.
  3. Finally, enter these values into the formula above. This yields an original price of 66.67$.


What is a percent off?

A percent off, also known as a discount, is a reduction in the price of an item that makes the good “on-sale”.

What is a normal percent off?

Anything above 25% off is considered a great deal. Be wary of businesses increasing their price, then claiming a large discount that only gets it back to the original price before it was increased.
