Online discount calculator

Subtract the discounted price from the original price, divide by the original price and multiply by 100: Discount = (original − sale price) ÷ original × 100. If something costs €140 instead of €200, that's (200 − 140) ÷ 200 × 100 = a 30% discount. Use the “Discount percentage” calculation for this.

Multiply the price by 1 minus the discount percentage divided by 100: final price = price × (1 − discount ÷ 100). For a 30% discount on €200, calculate 200 × 0.7 = €140. For a fixed discount, simply subtract it from the price.

Divide the price paid by 1 minus the discount percentage divided by 100: Original = sale price ÷ (1 − discount ÷ 100). If the price is 140 € after a 30 % discount, the calculation is 140 ÷ 0.7 = 200 €. A common mistake is adding 30 % to 140 €, which gives 182 €, not the original price. In the calculator, use “Original price.” A percentage discount there must be below 100 %; a fixed amount is simply added back.

Discounts do not add up. The second discount applies to the already reduced price: 100 € minus 20 % is 80 €, and a further 10 % off brings it to 72 €. The total discount is 28 %, not 30 %. Under “Price after discount,” use “Add another discount” to add up to two more percentage discounts. The calculator shows each step and the total discount.

With a 3-for-2 offer, you buy three items and pay for only two. The discount on the entire purchase is 1 − 2 ÷ 3, or about 33.3 %. A 2-for-1 offer gives 50 %, and a 4-for-3 offer gives 25 %. The calculator has a “3 for 2” tab with matching presets.

An early-payment discount is a price reduction for paying promptly. It is calculated like any other discount, on the already reduced amount. Under “Price after discount,” enter the first discount, then add the early-payment discount as another percentage discount. Example: 1,000 € minus a 10 % discount is 900 €; minus a 2 % early-payment discount is 882 €.

That depends on the seller or contract. Under “Price after discount,” you can optionally enter a tax rate between 0 and 100 %. It is added to the price after discount, and you see the final price including tax. If your discount applies to the price including tax, simply leave the field blank.

Yes. The calculator accepts both 19,99 and 19.99 and recognizes thousands separators such as 1.250,50. You can choose euros, US dollars, pounds, francs, zlotys, krona, or reais; the formatting of amounts follows your language.

No. The calculation runs in your browser; no prices are sent to a server to produce the result. Whenever you change something, your numbers appear in the address bar so you can share the result. “Share link” copies that exact address.
