What will you actually pay?
Enter the original price and the discount — as a percentage or a dollar amount — to see the sale price and how much you save. Retailers often stack offers like 30% off plus an extra 10% off; the calculator applies the extra discount to the already-reduced price, the way registers do, and shows the true combined discount (37%, not 40%).
Add your sales tax rate to see the final amount at checkout, since tax is charged on the discounted price. It's perfect for Black Friday, back-to-school and clearance sales.

Frequently asked questions
How do I calculate a discount?
Multiply the price by the discount percentage and divide by 100 to get the savings, then subtract it. 25% off $80 saves $20, so you pay $60.
Is 30% off plus 10% off the same as 40% off?
No. The extra 10% applies to the reduced price, so the total discount is 37%.
Is sales tax charged before or after a discount?
After, in most states: tax is calculated on the discounted price, which is how this calculator works. Manufacturer coupons can be treated differently in some states.
