Frequently Asked Questions
How do I calculate a percentage discount?
Multiply the original price by the discount percentage divided by 100 to get the saving, then subtract that from the original price. This tool does both steps for you instantly.
Can I enter a discount over 100%?
No. A discount above 100% would make the price negative, so the calculator only accepts a percentage between 0 and 100.
Does this include tax?
No. The discount is applied to the price you enter. If you need to add sales tax or GST afterwards, use a dedicated tax calculator.
Can I work out the discount percentage from two prices?
This tool starts from a percentage, but you can use the Percentage Change Calculator to find what percent one price is below another.
