Discount Calculator

Find the sale price and how much you save. Nothing leaves your browser.

Sale price

Percent off from two prices

How it works

Sale price = price × (1 − discount ÷ 100). A second discount is applied to the already-reduced price. Sales tax, if entered, is added to the discounted price. Results are rounded to the cent.

FAQ

How do I calculate a percentage discount?

Multiply the price by the discount percentage and subtract it. For example, 20% off $80 saves $16, so you pay $64.

What happens when two discounts are stacked?

They apply one after the other, not added together. 20% off then another 10% off is 28% off in total, not 30%.

Is sales tax added before or after the discount?

This calculator adds tax to the discounted price, which is how most US, Canadian and UK retailers charge it. Rules vary by store and place, so check your receipt.

How do I find the percent off from two prices?

Use the second tab: subtract the sale price from the original and divide by the original price.
