How to calculate a percentage off discount
Multiply the original price by the discount percentage to find the amount saved, then subtract that savings from the original price. For example, 25% off $100 saves $25 and leaves a sale price of $75.

How extra coupons are calculated
When a store offers an extra coupon, the second discount usually applies to the already-discounted price. A 20% discount followed by an extra 10% coupon is not the same as 30% off; it is an effective 28% discount.
How to find the percent off from a sale price
To reverse-calculate the discount, subtract the sale price from the original price, divide by the original price, and multiply by 100. This calculator does that in the compare sale price field.
