Discount Calculator

A discount calculator turns a "percent off" sticker into the two numbers you actually care about: the price you will pay and the amount you save. Enter the original price and the discount percentage, and the tool computes the final price as original x (1 minus rate), along with the savings, which is simply original minus final. A 20% discount on 80 gives a final price of 64 and a saving of 16. The genuinely useful feature, and the one most people get wrong, is stacked discounts. When a store offers "20% off, then an extra 10% off", those percentages do not add up to 30%. They apply one after another: 100 becomes 80 after the first cut, then 80 becomes 72 after the second, for a combined 28% off, not 30%. This calculator applies chained discounts sequentially so the result matches what the register will actually charge. The same logic explains why the order of two different percentage discounts does not change the final price, but adding a fixed-dollar coupon does depend on order. This is a pre-tax calculation: it works on the listed price and does not add sales tax or VAT, since tax rules and rates vary by region. If you need tax included, the VAT Calculator handles that step. Everything runs in your browser, so a store owner modeling an unreleased promotion or a buyer evaluating bulk pricing keeps that strategy entirely on their own device, away from analytics scripts and competitor scrapers. Use it to compare two sales quickly, to confirm a retailer's discount math, or to plan a promotion that hits a target final price.
