Overview
About the Discount & Sale Price Calculator
Calculate the final price after a percentage discount, see exactly how much you save, and optionally add sales tax to get the amount you pay at the register.
A discount calculator turns "20% off" into the number that matters: what you actually pay and what you actually save. Enter the original price and the percentage off, optionally add sales tax, and the final figure appears instantly.
The maths
savings = price × discount% ÷ 100
after discount = price − savings
tax = after discount × tax% ÷ 100
final = after discount + taxTax is applied to the discounted price, so the order matters.
Stacking discounts
Apply each discount to the running price one at a time. Percentages do not add: 20% then 10% is a 28% saving, not 30%, because the second discount applies to an already-reduced price.
Private and precise
Every figure is worked out in your browser with standard financial formulas. Nothing you type is uploaded, stored or sent anywhere.

Why use it
Benefits and common use cases
What this tool is good for, and what it deliberately does not try to do.
Tax like a real register
Optional sales tax is applied to the discounted price, matching how point-of-sale systems compute the total.
Compare deals
A bigger percentage off a higher price is not always the better bargain — this makes the real numbers obvious.
Questions
Frequently asked questions
Short, honest answers about quality, limits and privacy.
How do I stack two discounts?
Apply them in sequence, not by adding. A 20% discount followed by 10% off is price × 0.8 × 0.9 = 72% of the original, a 28% total saving — not 30%.
Is tax on the original or discounted price?
Almost always the discounted price. This calculator applies the tax rate after the discount, matching how point-of-sale systems compute it.
