“25% off, then an extra 10% off” is not 35% off, and the real number is smaller than the two discounts added together.

25% off, then 10% off, isn't 35% off
The second discount applies to the already-reduced price, not the original one, so it takes a smaller bite. €120 at 25% off is €90, then 10% off €90 is €81, a combined discount of 32.5%, not 35%. It's a small gap on paper and a real one on a big purchase, and it's exactly why "stack the coupons" always saves a little less than simple addition suggests.
Discount calculator FAQ
Why don't two stacked discounts just add together?
Because the second discount applies to the already-reduced price, not the original one. 25% off followed by an extra 10% off is not 35% off, it's 32.5% off: the 10% takes a smaller bite because it's 10% of a smaller number. This calculator applies stacked discounts in the correct order and shows the real combined percentage, which is always a little less than simply adding them.
How do I find the original price from a sale price?
Use "Find original price" mode: enter the sale price and the discount percentage that was applied, and it divides back out to the pre-discount price. Useful when a receipt only shows the price you paid and the percentage off, not the original tag price.
What's the difference between "percent off" and "percentage points"?
Percent off is relative to the price: 20% off a €50 item saves €10. A percentage point is a difference between two percentages themselves, going from a 20% discount to a 25% discount is a 5-percentage-point increase, but it is not the same as "5% more off." Retail discounts almost always mean the first kind, which is what this calculator computes.
Can I use this for a fixed amount off instead of a percentage?
This calculator is built around percentage discounts, which is how most sales and coupons are actually advertised. For a flat amount off (say, "€10 off"), just subtract it directly, or enter it as a percentage of the price if you want to see the equivalent rate.

Why stacked discounts don’t just add up
The second discount applies to the already-reduced price, not the original one, so it takes a smaller bite in absolute terms. €120 at 25% off is €90, then 10% off €90 is €81, a combined discount of 32.5%, not 35%. It’s a small gap on a cheap item and a real one on an expensive purchase, and it’s the exact reason “stack the coupons” always saves a little less than simple addition suggests.
Working backward from what you actually paid
A receipt often shows the price you paid and the discount percentage, but not the original tag price, and dividing that out by hand is easy to get wrong in the wrong direction. This calculator’s reverse mode does the division correctly: enter the sale price and the discount that was applied, and it returns the price before the discount.
A percentage point is not the same as a percent
Going from a 20% discount to a 25% discount is a 5-percentage-point increase, but it is not “5% more off,” those are different measurements of the same change. Retail discounts almost always mean the first kind, the straightforward percent off the price, which is exactly what this calculator computes.
