Calculate Discounts & Savings

Use the formula: Discount Percentage = ((Original Price - Sale Price) / Original Price) × 100. For example, if an item costs $80 instead of $100: ((100 - 80) / 100) × 100 = 20% discount.

Use the formula: Sale Price = Original Price - (Discount Percentage / 100 × Original Price). For example, a 25% discount on a $100 item: $100 - (25/100 × $100) = $100 - $25 = $75.

Use the formula: Original Price = Sale Price / (1 - Discount Percentage / 100). For example, if an item costs $60 with a 40% discount: $60 / (1 - 40/100) = $60 / 0.6 = $100.

Original price is the regular price of an item before any discounts are applied. Sale price is the final price after the discount has been subtracted from the original price.

Amount Saved = Original Price - Sale Price. For example, if an item is discounted from $100 to $75, you saved $25. This is the same as the discount amount.

Yes! Our calculator can determine the missing value when you provide any two of the three: original price, discount percentage, or sale price. Just leave the field you want to calculate empty.

Good discount percentages vary by industry and product. Retail typically offers 10-30% off, clearance sales may offer 50-70% off, and seasonal sales often provide 20-40% discounts. Consider the product's value and your budget.

For multiple percentage discounts, apply them sequentially. For example, 20% off then 10% off: First discount = Original Price × 0.80, Second discount = First Result × 0.90. Note that 20% + 10% ≠ 30% - the total discount is actually 28%.

Sales tax is typically calculated on the final sale price, not the original price. For example, if a $100 item has a 20% discount and 8% tax: Sale Price = $80, Tax = $80 × 0.08 = $6.40, Total = $86.40.

Common strategies include percentage off (10%, 20%, 50% off), buy-one-get-one (BOGO), clearance sales, seasonal discounts, loyalty member discounts, coupon codes, and flash sales. Each targets different customer behaviors and purchase timing.
