About this tool
How do you calculate a discount?
Multiply the original price by the discount percentage to find the saving, then subtract it. A 20% discount on 2,500 saves 500, so you pay 2,000.
Stacked discounts are where shoppers and sellers often get confused. "20% off plus an extra 10%" is not 30% off. The second discount applies to the already reduced price, so the total discount is 28%. This calculator shows the true combined discount every time.

Compare the final price
A bigger percentage off a higher starting price is not always the better deal.
Sellers: protect your margin
Before running a sale, check the discount against your profit margin.
Watch for tax
In many places tax is applied after the discount, so include it to see the real price.
