About Discount Calculator

The Discount Calculator works out the final price after a markdown. Enter the original price and a discount — either a percentage off or a flat amount off — and it shows the final price and exactly how much you save. You can stack a second discount and add sales tax on top.

Stacked discounts apply sequentially: the second percentage is taken from the already-reduced price, not the original. That is why “30% off plus an extra 20% off” saves 44%, not 50%. Tax, when entered, is applied to the discounted price, matching how stores charge at the register.

Use it at sale time to check whether a “deal” is real, compare a percent-off coupon against a dollar-off one, or predict the register total before you queue. Free and instant, straight in your browser.

Frequently asked questions

Multiply the price by the percentage and subtract: 25% off $80 is 80 × 0.25 = $20 off, leaving $60. The calculator does this instantly and also shows the saving as a currency amount.

No — they multiply. A 30% discount followed by an extra 20% leaves 70% × 80% = 56% of the original price, a total saving of 44%. The second discount always applies to the already-reduced price.

On the discounted price, which is how retailers normally charge. The calculator applies both discounts first, then adds tax to the result and shows the tax amount separately.

It depends on the price. On a $40 item, $15 off beats 25% off ($10); on a $100 item, 25% off ($25) wins. Enter each as a separate calculation and compare the final prices.

Yes — leave either field at 0 and it is ignored. The tool then computes a simple single-discount price, with or without tax.
