Discount Calculator
A discount takes a percentage off a price: the saving is the original price multiplied by the discount and divided by one hundred, and the final price is what is left. Enter the price and the discount to see both figures. Two successive discounts are not the sum of the two percentages.
Calculator
Formula
Discount = Price × Discount% / 100. Final = Price − Discount.
About This Calculator
What It Does
Calculate the final price of an item after a percentage discount. Enter the original price and the discount percentage to see both how much you save and the final sale price. Also supports reverse calculation — if you know the sale price, find the original price or the discount percentage.
Worked Example
Example 1 — Simple discount: A $100 item with 20% off. Discount = $100 × 20 ÷ 100 = $20 saved. Final price = $100 − $20 = $80. Example 2 — Large discount: A $250 coat at 50% off. Discount = $250 × 50 ÷ 100 = $125 saved. Final price = $250 − $125 = $125. You pay half. Example 3 — Multiple discounts: A $200 item discounted 30% then an extra 10% off the sale price. First discount: $200 − $60 = $140. Second discount: $140 − $14 = $126. Total savings: $74 (37% off original). Stacked discounts do not add to 40% — the second applies to the reduced price.
Real-World Usage
Use during sales events, Black Friday, Cyber Monday, clearance sales, and seasonal promotions. Compare discounts across stores to find the best deal. Calculate the true cost of a bulk or wholesale discount. Verify that an advertised discount matches the actual savings at checkout. Useful for pricing strategies in retail businesses.
Local Context
Most countries display prices including VAT/tax, so the discount applies to the tax-inclusive price. In the US and Canada, sales tax is added at checkout and the discount applies to the pre-tax subtotal. Percentage discounts are a universal retail concept and work the same way worldwide.

Frequently Asked Questions
How do I calculate a discount?
Multiply the original price by the discount percentage, then divide by 100. Example: 20% off $50: 50 × 20 ÷ 100 = $10 discount. Sale price = $50 − $10 = $40.
What is the difference between a discount and a coupon?
A discount is a percentage or fixed amount off the regular price, applied automatically at checkout. A coupon is a code or voucher that must be presented to receive the discount.
What is a typical discount percentage in retail?
Retail discounts range from 10-50%. End-of-season sales offer 30-50% off. Clearance items reach 70% off. Luxury brands rarely discount more than 20%.
