Discount Calculator
Find the sale price and how much you save on any discount.
How Discounts Are Calculated
A discount removes a percentage of the original price. Retailers advertise the percent off, but what shoppers actually want to know is the final price they'll pay and how much they're saving in real dollars.
sale price = original price × (1 − discount ÷ 100)
Example: a $150 jacket at 30% off saves you 150 × 0.30 = $45, bringing the sale price to $105. If you're instead trying to raise a price rather than lower it, see the Percentage Increase Calculator.
Watch out for stacked discounts — "30% off, then an extra 20% off" is not 50% off. The second discount applies to the already-reduced price, so the combined savings is actually 44%.
Frequently Asked Questions
How do you calculate a discount?
Multiply the original price by the discount percentage divided by 100 to find the amount saved, then subtract that from the original price to get the sale price.
How do you calculate the original price from a sale price?
Divide the sale price by (1 minus the discount as a decimal). For example, if an $80 item was discounted 20%, the original price was 80 ÷ 0.80 = $100.
How do I stack two discounts?
Apply the first discount to the original price, then apply the second discount to that already-discounted price. Discounts are not simply added together, since each one applies to a smaller amount.
