For sales like "20% off, then an extra 10% off", this tool calculates the final price and the true effective discount rate when discounts are applied in stages. Since discounts don't simply add up, this shows you exactly what stacking them really means.
How to use
- Enter the original price.
- Enter each discount rate in the order it's applied (use "Add discount step" to add more).
- The effective discount rate, total discount amount, and final price are calculated automatically.
FAQ
Does 20% off plus 10% off equal 30% off?
No. Each discount is applied to the price remaining after the previous discount, not to the original price, so 20% + 10% stacked works out to an effective 28% off.
Does the order of the discounts change the result?
No โ multiplication is commutative, so the final price is the same regardless of the order the discounts are applied in.
How many discount steps can I stack?
You can add up to 5 discount steps.
