Discount Calculator
Find the final price after applying a percentage discount.
About the Discount Calculator
Figuring out a sale price by hand is easy to get wrong, especially with stacked discounts or odd percentages. This calculator finds the exact final price after a percentage discount, along with the total amount saved.
It's useful for shopping, comparing deals, or checking a store's advertised discount against the price shown at checkout.
How to Use This Tool
- 1Enter the original price of the item.
- 2Enter the discount percentage being offered.
- 3The calculator shows the discount amount and the final price instantly.
How the discount is calculated
Discount amount = Original price × (Discount % ÷ 100). Final price = Original price − Discount amount.
For stacked discounts (e.g., 20% off, then an extra 10%), apply each discount to the result of the previous one rather than adding the percentages together — 20% + 10% is not the same as 30% off.
Frequently Asked Questions
Is 20% off plus 10% off the same as 30% off?
No. Stacked discounts apply sequentially, so the combined discount is actually less than the sum — for example, 20% off followed by 10% off equals a 28% total discount, not 30%.
Does this include sales tax?
No — this calculates the discount only. If tax applies, calculate it separately on the discounted price, since tax is typically charged after the discount is applied.
