Discount Calculator
Enter an original price and a discount percentage, and instantly see the sale price you'd pay and the dollar amount you'd save. The math is simple — (price x discount%) = savings, price - savings = sale price — but having it one click away saves mental arithmetic when comparing deals.
This is useful for quick price checks while shopping, verifying sale tags in stores, calculating bulk discount tiers, or sanity-checking promotional pricing before publishing it. Results update live as you type.

Frequently asked questions
How is the sale price calculated?▼
Sale price = original price - (original price x discount % / 100). For example, a $80 item at 25% off: savings = $80 x 0.25 = $20, sale price = $80 - $20 = $60.
Can I calculate the discount percentage from two prices?▼
This tool takes price and percentage as inputs. To find the percentage discount between two prices, use: ((original - sale) / original) x 100. For example, $100 to $75 = (25/100) x 100 = 25% off.
Does this include sales tax?▼
No — this calculates the pre-tax discounted price only. Sales tax varies by location and is applied after the discount. Your final checkout price will be the sale price plus applicable tax.
