The two most common discount types are percentage-based (e.g. 20% off) and fixed-amount (e.g. $15 off). Percentage discounts scale with the price, so higher-priced items save more in dollar terms. Fixed-amount discounts take a set dollar value off regardless of the original price. See also our Percent Composition.
To find the discount percentage, subtract the sale price from the original price, divide the result by the original price, and multiply by 100. For example, if an item costs $120 and sells for $90, the discount is ((120 − 90) / 120) × 100 = 25%.
Multiply the original price by 0.20 to find the discount amount, then subtract it from the original price. For example, 20% off $90 = 0.20 × $90 = $18 savings, giving a final price of $72. Alternatively, multiply the original price by 0.80 to get the sale price directly.
Simply move the decimal point one place to the left to get 10% of the price. For example, 10% of $45 is $4.50, so the final price would be $45 − $4.50 = $40.50. You can also multiply the original price by 0.90. You might also find our use the Average Percentage Calculator useful.
The discount is the amount or percentage subtracted from the original (list) price. The sale price is what you actually pay after the discount is applied. Together: Sale Price = Original Price − Discount Amount.
Fake discounts occur when a seller artificially inflates the 'original' price before applying a discount, making the deal look better than it actually is. Always compare the final sale price to prices at other retailers to verify you're getting a genuine deal.
Stacked discounts apply multiple percentage discounts in sequence, each applied to the already-reduced price. For example, 20% off followed by 10% off is not the same as 30% off — it equals 28% off total, because the second discount applies to the lower price after the first discount.
In Excel, if the original price is in cell A1 and the sale price is in B1, use the formula =((A1-B1)/A1)*100 to get the discount percentage. To calculate the sale price from a percentage discount, use =A1*(1-C1/100) where C1 contains the discount percentage.
