The discount amount is the original price multiplied by the discount percent. The final price is the original price minus that discount.

Discount formula explained

A percentage discount removes a share of the original price.

Discount = Price x rate / 100; Sale price = Price - Discount

Original listed price
Rate
Percentage taken off

Worked example

20% off $50 removes $10 and leaves a $40 sale price.

Practical tips

  • Apply discounts in order

    Two successive discounts do not simply add because the second applies to the reduced price.

  • Add tax afterward when required

    Local rules determine whether tax uses the original or discounted price.

About the Discount Calculator

The Discount Calculator finds how much you save and what you pay after a percentage discount on a price.

The discount amount is the original price multiplied by the discount percent, and the final price is the original price minus that amount.

For example, a 20 percent discount on 1,000 gives a final price of 800 and a saving of 200. You can choose your currency, and all maths runs in your browser.

Frequently asked questions

How is a discount calculated?
Multiply the original price by the discount percent to get the discount amount, then subtract it from the price to get the final price.
Can the discount be more than 100 percent?
No. A percentage discount is limited to 100 percent, which would make the item free.
Is this the same as percentage off?
The maths is the same. The Percentage Off Calculator is a quicker, simpler version for everyday shopping.
