Calculate a percent-off discount, dollar savings and final sale price from an original price.
Percentage change, discounts, tax, tips and everyday percent-of-number questions.
Choose whether the discount is a percentage or a fixed dollar amount, then enter the original price and discount value. Add an optional sales-tax rate to estimate the final checkout price.
For a fixed-dollar discount, the entered dollar amount is subtracted directly from the original price.
| Original price | Discount | Sale price |
|---|---|---|
| $100 | 10% off | $90 |
| $100 | 15% off | $85 |
| $100 | 20% off | $80 |
| $100 | 25% off | $75 |
| $100 | 30% off | $70 |
This calculator applies sales tax after the discount. For more detail, see how to calculate sales tax and total, 20 percent off $100, or 15 percent off examples.
A $240 item discounted by 15% is reduced by $36 to $204. At a 6% tax applied to that discounted amount, tax is $12.24 and the final price is $216.24.
What to check: Coupon stacking, sales tax rules, and exclusions can differ by store and location. A 15% discount followed by a 15% price increase does not restore the original price.
Compare with the Sales Tax calculator when that better matches the question you are trying to answer.
Yes. Choose Dollar amount and enter the amount to subtract.
No. A fixed discount larger than the original price is capped at the original price.
For tax after the discount, use the Sales Tax Calculator.
