Frequently Asked Questions
How does a double discount work?
A double discount applies two percentage discounts sequentially. The second discount is applied to the already-reduced price, not the original price.
For example, 20% off then 10% off a 100 dollar item gives 80 dollars after the first discount, then 72 dollars after the second. The total effective discount is 28%, not 30%.
This is how most retail stacking promotions work in practice.
Why is a double discount not the same as adding the percentages?
Because the second discount is calculated on the already-reduced price. Each subsequent discount operates on a smaller base amount.
The total effective discount of two stacked discounts is always less than their arithmetic sum.
Our calculator shows you the true effective discount percentage so there are no surprises.
Can I use this for bulk pricing calculations?
Yes. Enter the per-unit price and the discount percentage. Multiply the final price by the quantity to get your bulk total.
For quantity-based tiered pricing, run the calculator multiple times with different discount levels.
The tool is flexible enough for any scenario involving percentage-based price reductions.
Does the order of discounts matter?
Mathematically, the order of two percentage discounts does not change the final price. 20% then 10% gives the same result as 10% then 20%.
This is because multiplication is commutative. However, some retailers may apply discounts differently in practice.
Always check the specific terms of promotional offers to confirm how discounts are stacked.
