Sale Price

After discount.Usage Tip
To check a sale fast: 25% off means you pay three-quarters; 50% off is half; 75% off is a quarter. If the math is hard to do in your head, the deal may be dressed up to look bigger than it is.
THE MATH
Amount saved = price × discount%
Sale price = price − amount saved
With tax = sale price × (1 + tax%)
Sale price = price − amount saved
With tax = sale price × (1 + tax%)
The discount comes off the original price; sales tax (if any) is usually applied to the discounted price, not the original.
Stacked coupons apply one after another, not added together — 20% then 10% off is not 30% off.

Percent off is taken from the original price, so the dollar saved grows with the price.
When discounts stack, each applies to the running total, so the combined discount is less than the sum — 20% then 20% is 36% off, not 40%.
Sales tax is normally charged on the post-discount price, which is in your favor.
