Free discount calculator. Find the sale price and how much you save from a percentage off.
Savings = price × discount ÷ 100. Final price = price − savings. Example: 120 with 20% off saves 24 and costs 96.
Multiply the price by the discount percentage and divide by 100. Subtract that from the price to get the sale price.
Divide the sale price by (1 minus the discount as a decimal). A 20% off price of 80 started at 100.
