Discount Calculator

Work out the final price of a reduced item and how much you save: enter the original price and the discount percentage. It also works in reverse, to check what discount you are actually being given.

Pick what you want to work out and fill in the two fields. The same calculator does percentages, discounts and increases. For example, 20% of 100 is 20.

1

Final price and saving

A 30% discount on €80 leaves a final price of €56 and a €24 saving. The calculator shows both figures, because in a sale you usually want both: one decides whether you buy, the other whether waiting was worth it.

2

Successive discounts do not add up

A 30% sign in the window plus a further 10% at the till is not 40%. The second discount applies to the already-reduced price: €80 less 30% is €56, less another 10% is €50.40, which against the original is 37%. That is the difference between what looks like an offer and what it is.

3

Checking the advertised discount

If you know the original and reduced prices, you can check the real percentage: divide the saving by the original price and multiply by a hundred. Useful for verifying an "up to 50%" sign that turns out to be considerably less in your size.

4

The starting price matters

A percentage only means something against a genuine reference price. If the original was raised before the sale, the advertised discount is calculated on an inflated base. Spanish pricing rules require the advertised previous price to be the lowest applied in the preceding thirty days, precisely for that reason.

Worked example

Example: a €120 jacket at 25% off comes to €90, saving €30. If a further 10% is applied at the till, the final price is €81: a total saving of €39, which against the original €120 is 32.5%, not the 35% you would get by adding the two percentages.

Frequently asked questions

How do you calculate a discount?
Multiply the price by the percentage and divide by a hundred to get the saving, then subtract it from the price for the final amount. 25% of €120 is a €30 saving and €90 to pay.
Do two consecutive discounts add up?
No. The second applies to the already-reduced price, so the total is always less than the sum. 30% then 10% is equivalent to 37% off the original, not 40%.
How do I know what discount I actually got?
Subtract the price paid from the original, divide by the original and multiply by a hundred. If a €60 item cost you €45, the discount was 15 ÷ 60 × 100 = 25%.
Is the discount applied before or after VAT?
In Spanish retail, prices are advertised with VAT included, so the discount applies to the final price on the label. In business-to-business invoicing, where prices are usually quoted without VAT, the discount applies to the taxable base and VAT is calculated afterwards.
