Work out the final price and how much you save on any discount.
The Discount Calculator tool works out the final price after a percentage discount, and how much you save. Calculation runs in your browser, so your figures stay private.
Quickly compare sale prices during shopping, verify a store discount, or plan a promotion without doing the percentage maths in your head.
Discount maths is easy to get wrong in your head, especially when a price tag shows a percentage off and you need to know the final amount at the till. A 35 percent discount on a 79.99 item is not a number most people can compute accurately on the spot, yet shops rely on exactly that mental fog to make a deal look better than it is. This tool gives you the exact saving and final price in an instant.
The tool is also useful for retailers and small business owners setting sale prices: enter the original price and the discount percentage you want to offer, and read both the discount amount and the final price immediately. You can stack discounts by applying one, then using the result as the original price for the next.
Discount calculation runs entirely in your browser using native JavaScript arithmetic. When you enter the original price and discount percentage, the tool multiplies the price by the percentage and divides by 100 to find the discount amount, then subtracts that from the original price to find the final price. Both figures update instantly as you type.
Your figures never leave your device — there is no upload, no server-side processing, and no copy retained after you close the tab. The calculation is instant because it operates on the values in memory. The calculation is currency-agnostic, so enter the price in any currency and the result uses the same unit.
For tax-inclusive prices, the tool calculates the discount on the price you enter, so add or remove tax separately if your prices are tax-inclusive. For related calculations, use the Percentage Calculator for general percentage maths, the Tip Calculator for bill splitting, and the Currency Converter if you are comparing prices across currencies.
