Discount Calculator
A discount of X% doesn't always mean what it seems at first glance, especially when several discounts are stacked or when the starting price has already been inflated before the offer is applied. This calculator gives you the exact final price and the amount saved from the original price and the discount percentage, so you can compare offers objectively before buying.
The formula is simple: final price = original price × (1 − discount/100). For example, an €80 item with a 25% discount ends up at 80 × 0.75 = €60, saving €20. The most common mistake is assuming two successive discounts add up: a 20% discount followed by another 10% doesn't equal a 30% total discount, but 28% (0.8 × 0.9 = 0.72), because the second discount applies to the already-reduced price, not the original.
Another thing to watch for is discounts on an inflated reference price: if a store raises the price 20% before announcing a 20% discount, the final price ends up practically the same as the original, even though the sign advertises a big sale. Comparing the final price calculated here with the product's real price history (for example, with price-tracking tools) is the only reliable way to know if a discount is genuine.
Also keep in mind that, depending on the country and type of product, the displayed price may or may not include taxes (VAT or other), and these are calculated on the already-discounted price, not the original one. If you're comparing prices across countries or stores with different tax policies, always compare final, tax-included prices.
Preguntas frecuentes
How is the final price with a discount calculated?
Multiply the original price by (1 − discount/100). A €50 item with a 30% discount costs 50 × 0.7 = €35.
Do two discounts, say 20% and 10%, add up to 30%?
No. Successive discounts apply one on top of the previous result, not added together: 20% + 10% successively equals a 28% total discount, not 30%.
How do I find the discount percentage if I know the original and final price?
It's calculated as (1 − final price/original price) × 100. For example, going from €100 to €75 is a 25% discount.
Does the final price include tax?
It depends on whether the original price you enter already includes it. The discount applies the same way either way; always check whether the store's listed price is with or without tax.
How do I spot a "fake" discount where the price was raised first?
Compare the final price calculated here with the product's real price history using price-tracking tools; if it matches pre-"sale" prices, the discount isn't real.
Does this work for fixed-amount coupons, like "€10 off"?
This calculator is designed for percentage discounts. For a fixed-amount coupon, simply subtract that amount from the original price.
How do I calculate total savings on a purchase with several items?
Apply the discount to each item separately and add up the amounts saved, especially if discounts vary by product category.
What's the difference between a "discount" and a "sale"?
In practice they're used as synonyms: both reduce the regular selling price by a percentage or fixed amount.
