How do I calculate a discount percentage?

To calculate a discount percentage, use this formula: (Original Price – Sale Price) ÷ Original Price × 100 = Discount Percentage. For example, if a $80 jacket is on sale for $60, the discount is ($80 – $60) = $20, then $20 ÷ $80 = 0.25, and 0.25 × 100 = 25% off. Our discount calculator performs this percentage discount calculator calculation instantly. You can also use the reverse calculation mode: enter the original price and sale price, and the tool will tell you exactly what percent off you're getting. This is perfect for comparing deals at different stores or verifying that a sale is actually as good as it seems.
