About this calculator
A percent-off sign is easy to read but harder to compute in your head when the numbers aren't round. This calculator gives you the exact saving and the final price the moment you type them in, so you know what you'll really pay before you get to the register.
The math is simple once you see it: multiply the original price by the discount as a decimal to get the saving, then subtract. A $120 jacket at 25% off saves $30, leaving $90. The percentage is always taken from the original price, which is why a bigger sticker price means a bigger dollar saving at the same percentage.
Two useful habits: stack the discount before sales tax (stores apply the markdown first, then tax the reduced price), and watch for '30% off then an extra 20%' offers — those don't add to 50%, they compound to 44% off, because the second cut is taken from the already-reduced price. To add tax to your final figure, jump to the sales-tax calculator.
Frequently asked questions
How do I calculate a percentage discount?
Multiply the original price by the discount percentage as a decimal to get the saving, then subtract it. A $120 item at 25% off is $120 × 0.25 = $30 off, so $90.
Do two stacked discounts add together?
No. '30% off then an extra 20%' is not 50% off. The second discount applies to the already-reduced price, so the combined discount is 44%.
Is the discount applied before or after tax?
Before. Stores mark the price down first, then charge sales tax on the reduced amount. Apply the discount here, then add tax with the sales-tax calculator.
