Enter the original price and discount percentage to instantly see the final price and how much you save.
Whether you're checking a single sale discount or figuring out how much you'll really pay after two stacked discounts (like a storewide sale plus a coupon code), doing the math by hand is easy to get wrong — especially with stacked percentages. This tool calculates both instantly.
All calculations run locally in your browser — nothing is sent to a server.
The tool multiplies the original price by the discount percentage to find the amount saved, then subtracts that from the original price to get the final price.
It calculates successive (stacked) discounts, like a 20% off sale plus an extra 10% off at checkout — the second discount is applied to the already-discounted price, not the original.
Because the second discount applies to the reduced price, not the original. Stacked discounts of 20% and 10% equal a combined 28% off, not 30%.
