Calculation breakdown

See the sale price first

Enter the original price and discount percentage to see what you pay and save immediately. Quick percentage buttons speed up common checks. Stacked discounts and tax are optional; reverse modes remain available for finding an original price or discount percentage.

Stacked discounts

Percentage discounts are applied sequentially rather than simply added. A second discount applies to the already reduced price.

Discount formula

savings = original price × discount ÷ 100
sale price = original price − savings

Stacked discounts are sequential

A 20% discount followed by another 10% discount is not a 30% total discount. A $100 item becomes $80 after the first discount and $72 after the second, for an effective 28% reduction.
