What the result means
The sale price is what you actually pay; the savings is how much comes off the original price. Stacked or coupon discounts apply one after another, so two percentages do not simply add up. Always compare the final price across stores rather than the headline percent off, since a bigger percentage off a higher starting price can still cost more.
Use the result this way
- Start with Discount amount, then use supporting outputs for context.
- Verify Original price and Discount before copying the result.
- Check the formula, example, and assumptions before reusing the answer.

Formula
For a percentage discount, sale price = original price x (1 - discount percent / 100), and you save original price x discount percent / 100. A 20% discount on a $50 item is $50 x 0.80 = $40, saving $10. For a fixed amount off, sale price = original price - amount off. Enter the discount percent as a whole number, so type 20 for 20%, not 0.20.
- Percentage off: multiply the price by (100 - percent) / 100. A quick check is that 25% off leaves you paying 75%, and 40% off leaves 60%.
- Fixed amount off: subtract the coupon or rebate value directly from the price. This is common for dollar-off coupons and mail-in rebates.
- Stacked discounts apply in sequence, not added together. 20% off then 10% off is 0.80 x 0.90 = 0.72, a 28% total discount, not 30%.
- Sales tax is normally calculated on the discounted price, not the original, so apply the discount first and add tax afterward.
- To find the percent off from two prices, divide the savings by the original price and multiply by 100. Saving $15 on a $60 item is 15 / 60 = 25% off.
Inputs
Enter the original (list) price, then choose the discount type. For a percentage discount, enter the percent off, such as 25 for 25%. For a fixed discount, enter the dollar amount taken off. The calculator returns the final sale price and the amount you save, so you can compare deals at a glance.
Example
A $120 jacket marked 30% off costs $120 x 0.70 = $84, a saving of $36. A $45 book with a $10 coupon costs $45 - $10 = $35. For a stacked deal of 20% off then an extra 15% off, apply them in order: $100 becomes $80 after the first cut, then $80 x 0.85 = $68 after the second, for a 32% total discount, not 35%.
FAQ
How do you calculate a discount?
Multiply the original price by the discount percent, then subtract from the price. For 20% off a $50 item: $50 x 0.20 = $10 off, so the sale price is $40. Or multiply directly by 0.80 to get $40.
What is 20% off of $50?
20% off $50 is $10 off, making the sale price $40. You calculate it as $50 x 0.20 = $10 saved, or $50 x 0.80 = $40 final price.
How do you calculate the percentage discount between two prices?
Subtract the sale price from the original, divide by the original, and multiply by 100. If an item dropped from $80 to $60, that is $20 / $80 x 100 = 25% off.
How do stacked discounts work?
Stacked discounts apply one after another, not added together. 20% off then an extra 10% off is 0.80 x 0.90 = 0.72, so you pay 72% of the original, a 28% total discount, not 30%.
Is the discount applied before or after tax?
The discount is applied first, and sales tax is calculated on the lower, discounted price. So subtract the discount, then add tax to the sale price.
How do I calculate a 25% discount quickly?
25% off means you pay 75% of the price. Find a quarter of the price and subtract it, or multiply the price by 0.75. On a $60 item, 25% off is $15 off for a $45 final price.
