Discount Calculator

Use this discount calculator to work out savings, final sale price, and the original price before a discount.

Use the discount calculator

These three discount calculations cover the most common shopping and pricing questions.

1) Discount amount and final price

Enter an original price and discount percentage.

2) Original price before discount

Enter the sale price and the discount percentage.

3) What percentage off is this?

Enter the original price and the sale price.

Worked examples

Example 1: 15% off 120 gives a discount of 18 and a final price of 102.
Example 2: If 85 is the price after a 15% discount, the original price was 100.
Example 3: From 200 down to 150 means a discount of 25%.

Frequently asked questions

How do I calculate the discount amount?

Multiply the original price by the discount percentage divided by 100.

How do I calculate the final sale price?

Subtract the discount amount from the original price.

Can the discount be more than 100%?

No. A discount of 100% would make the price zero, so normal sale calculations require less than 100%.

Who uses a discount calculator?

Shoppers, retail stores, resellers, and anyone comparing savings or sale prices.
