Calculate sale price, savings and discount percentage for any price.
A discount calculator is a free online tool that instantly calculates the final price of any item after a percentage discount is applied. It also shows you exactly how much money you are saving, making it perfect for comparing sale prices while shopping online or in store.
Quickly calculate the final price of sale items without doing maths in your head.
Calculate trade discounts, bulk pricing and promotional offers for business clients.
Work out how much a percentage-off coupon saves you on any purchase.
Compare prices across stores by calculating each discount to find the best deal.
Multiply the original price by 0.20 to get the discount amount, then subtract from the original. Example: £80 × 0.20 = £16 off, so final price = £64.
Final Price = Original Price × (1 − Discount% / 100). Or: Discount Amount = Original Price × (Discount% / 100).
Yes — use: Original Price = Discounted Price ÷ (1 − Discount%/100). If you paid £60 after a 25% discount: 60 ÷ 0.75 = £80 original.
