How it works
A discount is a percentage of the original price removed from the total. The calculator works out the saving first, then subtracts it to give the price you pay.
Use the quick buttons for the discounts you see most often, or type any percentage including decimals such as 12.5%.
Sale signs are often written as "up to" a percentage, and some stack a second discount on the already-reduced price rather than the original. If two discounts are applied one after another, run the calculator twice - putting the result of the first into the price field of the second. Two 20% discounts are not a 40% discount; they come to 36%.
Formula
Amount saved
price × (discount ÷ 100)
Price you pay
price − amount saved
Equivalent single discount for two stacked discounts
100 − (100 − d₁) × (100 − d₂) ÷ 100
Worked examples
200 at 25% off → save 50, pay 150
200 × 0.25 = 50 saved, so the final price is 200 − 50 = 150.
89.99 at 30% off → save 27.00, pay 62.99
89.99 × 0.30 = 26.997, which rounds to 27.00 saved and 62.99 to pay.
Two 20% discounts → 36% off in total, not 40%
100 becomes 80 after the first, then 80 becomes 64 after the second. The total saving is 36.
Frequently asked questions
Does this include sales tax or VAT?
No. It works purely on the price you enter. If your price already includes tax, the result also includes tax. If tax is added at the till, apply it to the final price this calculator gives you.
Can I enter a discount over 100%?
No. A discount above 100% would mean the shop paying you, so the calculator caps the input at 100% and tells you why.
How do I work out the percentage off if I only know the two prices?
Use the percentage calculator in "percentage decrease" mode. Enter the original price and the sale price and it will tell you the discount percentage.
Are decimal prices supported?
Yes. Prices such as 19.99 work exactly as expected, and results are shown to two decimal places.
