Percent Off Calculator

Multiply the original price by the discount percentage (as a decimal) to get the amount saved, then subtract that from the original price. For example, 25% off a $80 item is 80 × 0.25 = $20 saved, so the sale price is $80 − $20 = $60.

Sale price = original price × (1 − discount%). A quick shortcut: for 30% off, you pay 70% of the price, so multiply by 0.70. This calculator also adds sales tax on the discounted price if you enter a tax rate, giving you the true out-the-door total.

Almost always after. Retailers apply the discount first, then calculate sales tax on the lower, discounted price — so a coupon reduces the tax you pay too. This calculator follows that standard order: discount first, then tax on the sale price.

Stacked discounts multiply, they do not add. Take 20% off first (pay 80%), then 10% off that (pay 90% of the new price): 0.80 × 0.90 = 0.72, so you pay 72% of the original — a 28% total discount, not 30%. Run this calculator twice, using the first sale price as the second original price.

Percent off is a specific discount applied to a price to find savings and a sale price. A general percentage calculation can find any part of a whole ("what is 15% of 200"). For discounts and sales, percent off is the right tool; for other percentage questions, use a percentage calculator.
