Calculate your discount
Percentage discounts are applied sequentially. The fixed coupon is applied after percentage discounts, and tax is calculated last.

Discount calculator FAQ
What is a discount calculator?
A discount calculator turns an original price and one or more discounts into the final sale price, total savings, and effective percentage off.
How do I calculate a percentage discount?
Multiply the original price by the discount percentage, then subtract that savings amount from the original price. A 20% discount on $100 saves $20 and leaves a $80 sale price.
Do two 20% discounts equal 40% off?
No. Sequential discounts apply one after the other. Two 20% discounts reduce $100 to $80 and then $64, which is 36% off overall.
How can I find the percent off from a sale price?
Subtract the sale price from the original price, divide the savings by the original price, and multiply by 100. The sale-price mode performs that calculation instantly.
Is sales tax calculated before or after a discount?
Sales tax is usually applied to the discounted subtotal, but rules vary by location and coupon type. This calculator applies tax after entered discounts and coupons.
