Discount calculator
Calculate the final price after one or more percentage discounts — including stacked promotions like “30% off, then extra 10% at checkout.” See original price, each discount step, amount saved, and equivalent total discount percent. Stacked discounts apply sequentially to the reduced price, not the original — so two 20% offs yield 36% total, not 40%.

How to calculate discounts
1. Enter the original price before any reduction.
2. Add one discount percent or several stacked discounts in order applied.
3. Read final price, total savings, and effective combined discount.
4. Reverse-check: final price + savings should equal original.
Discount examples
Single 25% off €80 item
Discount €20; final price €60. Effective discount 25%.
Stacked 20% + 20%
€100 → 20% off = €80 → another 20% off €80 = €64. Total saved €36 (36% effective), not €40.
Black Friday triple stack
€240 jacket: 30% off → €168; extra 15% coupon → €142.80; 10% loyalty → €128.52. Nominal “55%” marketing ≠ 55% off €240 (which would be €108).
When to use this tool
• When retail ads stack coupons and you want the true checkout price.
• When you price products with wholesale markdowns plus seasonal promos.
• When you compare “€50 off” vs “25% off” on different base prices.
When to choose something else
• When VAT must be added after discount — use the VAT calculator next.
• When bulk tier pricing uses absolute thresholds, not percentages.
• When currency rounding per line item matters for legal invoices.
Marketing vs math
Stores advertise “up to 70% off” plus “extra 15% with code” knowing customers sum percents mentally. Always multiply retention factors: three steps of 10%, 15%, and 20% off mean multiply by 0.9 × 0.85 × 0.8 = 0.612, i.e. 38.8% total off — not 45%. This calculator applies that order so you can compare basket totals before checkout.
Discount vs margin for sellers
If you wholesale at €40 and MSRP €100, a 30% sale still leaves €70 — healthy retail margin. Stack too many promos and you erode margin below cost. Retailers use effective discount to plan campaigns; use the same math when running a small shop on Etsy or Shopify.
Frequently asked questions
Why is 20% + 20% not 40% off?
The second 20% applies to the already-reduced price. €100 × 0.8 × 0.8 = €64, equivalent to 36% off the original.
How do I find the original price from a sale tag?
If final is €75 after 25% off, original = 75 ÷ 0.75 = €100. This tool forward-calculates; divide by (1 − discount) to reverse.
Fixed amount vs percent stack?
Apply percent discounts first in the order stated, then subtract fixed-amount coupons unless terms say otherwise.
Does order of stacked percents matter?
Pure percentages commute: 10% then 20% equals 20% then 10%. Mixed with fixed amounts depends on store policy.
Can I enter more than two discounts?
Yes — add each sequential percent as applied at the register.
