How the percent off calculator works
The percent off calculator helps you estimate results using the assumptions and values you provide. Review the formula and example before relying on the result.
Formula and assumptions
Discount amount = original price × discount percentage ÷ 100. Sale price = original price − discount amount.
Example
A 20% discount on 100 saves 20, making the sale price 80.
