Enter values to begin.

How to Use This Discount Calculator

Enter the original price and the discount percentage. The calculator multiplies the price by the discount rate to show your savings in currency, then subtracts that from the original price to give the final price you'll actually pay.

Common Discount Tasks

Useful for checking a sale price at the till, comparing two competing discounts (for example 20% off versus a 15% coupon plus a smaller markdown), or working backward from an advertised "save €X" figure to confirm the percentage really matches the claimed discount.

Stacked Discounts Multiply, They Don't Add

"20% off, plus an extra 15% off" sounds like 35% off, but that's not how sequential discounts work. Each discount applies to whatever price is left after the previous one, not to the original price. Start with €100: 20% off brings it to €80. Take another 15% off that €80, not the original €100, and you get €68 — a total discount of 32%, not 35%. The gap grows with bigger or more numerous discounts, which is exactly why store promotions that stack multiple percentages often save you less than the headline numbers suggest.

FAQ

Can I stack two discounts with this calculator?

Not in one step. Run the first discount, take the resulting final price, and enter that as the original price for a second calculation to apply a second discount on top.

Does this include sales tax or VAT?

No, it only applies the discount percentage to the price you enter. Apply VAT before or after, depending on whether your original price already includes tax.

What if the discount is more than 100%?

The calculator will still compute it, but a discount above 100% produces a negative final price, which isn't meaningful in practice — double-check the percentage you entered.

If a store offers 20% off plus another 15% off, is that 35% total?

No — stacked discounts multiply rather than add. €100 with 20% off becomes €80; take another 15% off that €80 and you get €68, a 32% total discount, not 35%. Run each discount through this calculator in sequence, using the previous result as the next original price, to get the real total.
