Discount Calculator
Enter the original price and the discount. See the final price and how much you save. Add a second discount to see how stacked offers really work — they multiply, not add.
Quick answerFinal price = original price × (1 − discount ÷ 100). A $80 item at 25% off costs $60 and saves you $20. Two stacked discounts don't add: 20% + 30% off = 44% total, not 50%.

How to calculate a discount
Multiply the original price by the discount percentage to get the dollar savings. Subtract from the original price for the final price. To work backwards from a sale price, divide by (1 − discount/100).
