Discount / Sale Price Calculator

Work out the sale price and how much you save from an original price and a percentage discount. It runs in your browser.

How to use it

1. Enter the original price.
2. Enter the discount percentage.
3. Read the final price and the saving.

Formula and example

Sale price = original price × (1 − discount ÷ 100). A $120 jacket at 35% off costs 120 × 0.65 = $78.00, and you save $42.00.

Good to know

• Stacked discounts are not added. 20% off then an extra 10% off is 28% off, not 30%: 100 × 0.80 × 0.90 = 72. Run the first discount, then enter the result as the new price for the second.
• Working backwards: a sale price of $78 after 35% off started at 78 ÷ 0.65 = $120, not 78 plus 35%.
• “30% off” and “$30 off” are only equal at $100.

Tax, shipping and fees are usually added after the discount and vary by place. This is price arithmetic, not financial advice. See the guide.
