About Discount Calculator
Whether you're shopping a sale, negotiating a deal, or working out pricing, this discount calculator handles both directions of the math. In Forward Mode, enter the original price and discount percentage — the calculator instantly shows how much you save and what you'll actually pay.
Reverse Mode solves the inverse problem: if you see a sale tag showing the discounted price and the percentage off, it back-calculates what the original price was and how much the discount amounts to in dollars.
All calculations happen entirely in your browser with no data sent to any server. Results update live as you type, making it easy to compare different scenarios.
