What is a Percent Off Calculator?
A Percent Off Calculator instantly tells you the sale price and your savings when a percentage is taken off an item's original price. It's perfect for shopping, budgeting, and comparing deals.
How to calculate percent off manually (the formula)
The formula is: Sale Price = Original Price × (1 - Percent Off/100). First convert the percent off to a decimal, subtract it from 1, then multiply by the original price.
Example calculation
A $60 item is 30% off. Sale price = $60 × (1 - 30/100) = $60 × 0.70 = $42. You save $60 - $42 = $18.
Common mistakes
- Confusing percent off with fraction off — 30% off means you pay 70%, not 30% of the original price.
- Forgetting to convert the percentage — Always divide the percent by 100 first (30% = 0.30).
- Not checking if tax is included — Percent off usually applies to the pre-tax price. Tax is added afterward.
