Discount Calculator

How to calculate a discount

Multiply the original price by the discount percentage to find the savings, then subtract those savings from the original price.

Example

A 25% discount on $100 saves $25, so the sale price is $75 before tax.

Use the final price, not just the percent

Comparing final prices makes it easier to judge whether a sale is actually a better deal. Add sales tax separately when you need the checkout total.

Keep calculating

Need the checkout total? Use the Sales Tax Calculator. Comparing package sizes? Use the Unit Price Calculator. For markups and business pricing, use the Profit Margin Calculator.

Make the savings decision clearer: After you calculate the sale price, compare the final checkout amount with the Sales Tax Calculator and compare competing package sizes with the Unit Price Calculator. This keeps the decision focused on what you actually pay, not the headline discount alone.
