How to use the discount calculator
- Enter the original price and the discount.
- Add an extra discount or sales tax if there is one.
- Or enter an original and a sale price to see how big the discount is.
20% off and then 10% off is not 30% off
A second discount is taken off the already reduced price. 20% off 100 is 80, and 10% off 80 is 72: together that is 28% off, not 30%.
Frequently asked questions
Is tax added before or after the discount?
After. Sales tax is charged on the price you actually pay, so the calculator applies discounts first and then the tax.
Is anything sent anywhere?
No. The calculation happens in your browser, and the prices you enter never leave your device.
