Discount Calculator
Enter the price and the discount percentage — instantly see how much you save and the final amount you pay.
What is the Discount Calculator?
The Discount Calculator turns a marked price and a discount percentage into the exact amount you will save and the final price you pay. Add an optional tax percentage and it also produces the tax component and the total you would see on the bill.
The tool is designed for both shoppers and small businesses: shoppers can double-check flashy "70% off!" signs, and shopkeepers can price-tag items faster without opening a spreadsheet.
All maths runs in your browser, so no shopping habits or invoice details are shared with any server.

Frequently asked questions
Does the tax apply before or after the discount?
After. The discount reduces the base price, then tax is added to that new base — matching most retail practices.
Can I calculate multiple discounts stacked?
Apply the first discount, copy the result into the price field, then apply the second discount for a stacked calculation.
Which currency does the tool use?
None specifically — the numbers work in any currency you want to type in.
Is my data stored?
No. Everything runs in your browser tab.
What if the discount is a flat amount instead of a percentage?
Enter the flat amount as a percentage of the price manually, or subtract it in your head before opening the tool.
