Calculate discounts, find original prices, and stack sale savings.
See the real total discount when two sales are stacked
Extra 10% off already 20% off = 28.0% total (not 30%)
Whether you are shopping on Black Friday, browsing an end-of-season clearance, or comparing deals at different stores, this discount calculator shows you exactly what you will pay and how much you save. Choose from three modes depending on what you already know. If you have the original price and the discount percentage, use the default mode to see the final price. If you know the sale price and the discount but want to find the original tag price, switch to Find Original Price. And if you see both the original and sale price but want to know the exact percentage off, use Find Discount Percent. Quick-select pills for common discount amounts let you compare savings in a single click.
Many retailers offer stacked discounts: an extra 20 percent off already reduced items, for example. A common mistake is to simply add the two percentages together, but that overstates the real savings. When you take 20 percent off and then another 10 percent off, the true total discount is 28 percent, not 30 percent. The Stack Discounts section below the main calculator shows you the real combined discount so you know the actual deal you are getting. Use it to compare coupon combinations, loyalty discounts on top of sales, or any scenario where multiple discounts apply.
The visual price tag at the top shows the original price with a strikethrough next to the final price so you can see the impact of the discount at a glance. This is useful when comparing items side by side or sharing a deal with friends. All calculations happen instantly in your browser with no server calls and no data stored.
