Frequently asked questions
How do I calculate a discount?
Multiply the original price by the percent off to get the saving, then take it off the original price. 20% off 49 saves 9.80, so the sale price is 39.20.
How do I find the percent off between two prices?
Take the sale price off the original price, divide by the original price and multiply by 100. From 50 down to 35 is 15 ÷ 50, so 30% off.
What if I fill in both the percent off and the sale price?
The calculator uses the percent off and says so under the result. Clear the percent off to work from the sale price instead.
How much of a discount can I afford?
A discount comes straight out of your profit. On a product you sell for 100 that costs you 60, 20% off cuts your profit per sale from 40 to 20. Check your margin with our markup calculator before you set the percent.
