10 Percent Off Calculator

Calculate the sale price after a discount, see how much you save, and stack a second discount on top.

Processing... 0%

Result

This page opens the discount calculator with 10% already filled in — type the original price and the sale price appears immediately, together with the exact amount you keep in your pocket. 10% off means you pay 90% of the price: 90 instead of 100, 45 instead of 50.

Ten percent is the easiest discount to check mentally: move the decimal point one place to the left and that is your saving. On a 249.99 item that is 25.00 off, leaving 224.99. It is also the typical size of a first-order coupon, a newsletter sign-up reward or a loyalty-card perk, so it is worth recognizing at a glance.

Use the optional extra-discount field to model stacked promotions — for instance 10% off on top of an existing sale — and the calculator will show the price after each step and the true combined discount. Everything runs locally in your browser as you type.
