Calculate Discounts and Final Prices Instantly
Shopping a sale? Our discount calculator helps you figure out exactly how much you'll save and pay. Calculate single discounts, stacked discounts (like an extra 20% off sale prices), and see the final price with sales tax. Know your true savings before you buy.
How Discount Calculations Work
A discount reduces the original price by a percentage. For a 25% discount on $100, you save $25 and pay $75. When stacking discounts, the second discount applies to the already-reduced price, not the original. Adding sales tax increases the final amount you pay.

Final Price = Original × (1 - Discount%) × (1 + Tax%)How to Calculate a Discount

Frequently Asked Questions
Stacked discounts apply sequentially, not together. A 30% discount plus 20% extra isn't 50% off. First 30% comes off ($100 becomes $70), then 20% off the new price ($70 becomes $56). Total savings: 44%, not 50%.
