Calculate sale prices, discounts, and savings percentage
Calculating discounts by hand can be surprisingly tricky, especially when stacking multiple offers or comparing deals across stores. Our free discount calculator instantly shows you the final sale price, the dollar amount you save, and the original price side by side -- so you always know exactly what you are paying.
To calculate a discount manually, multiply the original price by the discount percentage expressed as a decimal, then subtract that amount from the original price. For example, 25% off a $80 item means $80 x 0.25 = $20 off, giving you a final price of $60. When stacking discounts, apply each one sequentially to the reduced price rather than adding the percentages together.
Major retail discount periods such as Black Friday, Cyber Monday, end-of-season clearances, and holiday sales are prime opportunities to save. Smart shoppers compare the per-unit price, check whether a coupon applies before or after a sale discount, and set a budget in advance. Use this calculator at the store or at home to verify advertised savings and make confident purchasing decisions.
