Discount Calculator
🏠 Free ToolCalculate the final price after one or two stacked discounts. See your total savings, effective discount percentage, and a clear breakdown of how each discount contributes to the final price.
How it Works
The discount calculator instantly shows you the final price after applying one or two percentage discounts. Enter the original price and discount percentage to see how much you save and what you actually pay.
For single discounts, the calculator is straightforward: it shows the savings amount and the final price. The visual bar illustrates the proportion of the price you pay versus the portion you save.
The stacked discount feature is where this tool really shines. When stores offer “extra 10% off sale prices,” many shoppers assume a 20% sale plus 10% extra equals 30% off. In reality, it equals 28%. This calculator makes the math transparent.
The per-discount breakdown shows exactly how much each discount contributes when they are stacked, helping you evaluate whether a second discount offer is as generous as it appears.
Frequently Asked Questions
How do stacked discounts work?
Stacked discounts are applied sequentially, not added together. A 20% discount followed by a 10% discount means the second 10% applies to the already-reduced price, not the original. So 20% + 10% stacked = 28% total, not 30%.
Why is the effective discount less than the sum of both discounts?
Because the second discount applies to a smaller amount (the price after the first discount). Each successive discount has a diminishing absolute effect since it is calculated on a progressively lower base.
How do I calculate the final price after a percentage discount?
Final price = Original price × (1 - discount/100). For a 25% discount on 80 EUR: 80 × 0.75 = 60 EUR.
Can I use this for coupon stacking?
Yes. Enter your first coupon or sale discount, then the second coupon in the stacked field. The calculator shows the true effective discount and final price when both are applied.
How do I calculate the original price from a discounted price?
Original price = Discounted price / (1 - discount/100). If you paid 60 EUR after a 25% discount, the original was 60 / 0.75 = 80 EUR.
