Discount Calculator

Calculate percent-off discounts, sale price, savings, and optional sales tax after a discount.

Formula

A discount is the original price multiplied by the discount percentage. The sale price is the original price minus the discount.

discount amount = original price × discount% ÷ 100 sale price = original price - discount amount

20% off $150: discount = $150 × 0.20 = $30. Sale price = $120.
35% off $80: discount = $28. Sale price = $52.
Two discounts usually apply one after another, not by simply adding percentages.

Short, practical answers for this calculation.

Multiply the original price by 0.20 to find the savings, then subtract the savings from the original price.

No. Two 50% discounts reduce the price to 25% of the original, not zero.

Many stores calculate sales tax after the discount, but rules vary by location and product.
