What is a discount calculator?

A discount calculator shows the sale price after a percentage is taken off, and how much you save. It is handy for shopping, sales and working out "percent off" deals.

How it works

It multiplies the original price by the discount percentage to find the amount saved, then subtracts that from the price for the final cost. Example: 25% off an 80 item saves 20.00, for a final price of 60.00.

How to use

Enter the original price and the discount percentage. The calculator shows the amount saved and the final price instantly. Add a sales tax percentage if you want tax applied after the discount.

All money values are rounded to two decimal places. The tool is currency-neutral.
