Sale price and savings after a discount, an extra discount on top, and tax
Estimates only, not financial advice. What you type stays on your device. Updated on 24 Oct 2026.A discounted price is the original price times one minus the discount, so 40% off 2,499 leaves 1,499.40. A second discount applies to that reduced price, so an extra 10% off brings it to 1,349.46, a combined 46% saving rather than 50%.
Type the Original price.
Choose whether the discount is a Percentage or a fixed Amount, and enter it.
Add an Extra discount if the shop takes more off at checkout, and a Tax rate if tax is added after the discount.

Sale tags rarely tell the whole story. A shop advertises 40% off, then takes an extra 10% at the till, and then adds tax; the price you actually pay needs three steps, and the second discount is smaller than it looks because it comes off an already reduced price. This calculator does the steps in the order shops use and shows what each one is worth.
How it is worked out. The first discount comes off the original price, either as a percentage or as a fixed amount such as 200 off. The extra discount is a percentage of the price after the first one. Tax, if you add a rate, is charged on the price after both discounts, which is how GST in India, VAT in Europe and US sales tax are normally applied. The page then shows the sale price, the tax, what you pay, the total saved, and both discounts as a single percentage of the original price.
Why two discounts do not add up. Ten percent off and then another ten percent off is 19% in total, not 20%, because the second ten percent is taken from 90, not 100. In the same way 40% then 10% is 46%, and 50% then 50% is 75%, never free. The combined figure on the page makes it easy to compare a "40% + 10%" offer with a flat 45% off elsewhere.
What it does not do. It does not know any shop's rules: whether a coupon applies before or after tax, whether a fixed discount needs a minimum basket, or how a store rounds. Tax is a rate you enter; the calculator does not look up GST slabs or a US state rate. For a business setting a price from cost and margin, the profit margin calculator is the better tool.

Multiply the original price by one minus the discount as a decimal. For 30% off 1,500, multiply 1,500 by 0.7 to get 1,050, a saving of 450. Type the price and 30 into the calculator and both figures appear, with any tax added after.
No. The extra 10% is taken from the price that is already 40% lower, so the two together are 46% off. On a 2,499 item that is 1,349.46 rather than 1,249.50. The calculator shows the combined percentage so offers can be compared fairly.
Usually after. GST in India, VAT in the UK and Europe, and US sales tax are normally charged on the price you actually pay once discounts are taken off. Enter the tax rate and the page adds it to the discounted price, as most till receipts show.
Subtract the sale price from the original, divide by the original and multiply by 100. A shirt cut from 1,200 to 900 is 300 off, and 300 divided by 1,200 is 25%. The percentage change mode of the Percentage Calculator does this in one step.
Yes. Switch the discount type to Amount and type the money off, such as 200 off a 1,500 order. The page then shows that saving as a percentage of the price too, and an extra percentage discount can still be added on top.
No. The tax rate is a number you enter, because it depends on the product and the place: GST slabs in India, VAT bands in Europe and each US state's sales tax. Leave it at 0 when the advertised price already includes tax.
