What a Percent Off Discount Means

A percent off discount reduces the original price by a given percentage. The result is the sale price, and the difference is the amount saved.

How to Calculate Percent Off

  1. Multiply the original price by the percent off divided by 100.
  2. Subtract that discount amount from the original price.
  3. Read the result as the sale price.
  4. The discount amount is the amount you save.
sale price = original price x (1 - percent off / 100)

Worked Example

Example: $80 with 30% off becomes $56.

80 - (80 x 30 / 100) = 56

Frequently Asked Questions

Can percent off be greater than 100?

In a normal retail setting, no. A full discount means the item is free.

Does this accept decimals?

Yes. Any finite real prices are accepted.

What if the original price is zero?

The sale price is zero and there is nothing to discount.

Is this the same as a markup?

No. A markup increases a price, while percent off decreases it.
