How this calculator works
Stacked discounts are applied sequentially, not added together.
A 20% discount followed by another 10% discount is an effective 28% reduction, not 30%, because the second discount is applied to the already-reduced price.
Example: 20% off, then another 10%
$100 becomes $80 after the first discount and $72 after the second, for $28 total savings.
Frequently asked questions
Can I add two discount percentages together?
Not for sequential discounts. Apply each discount to the price remaining after the previous discount.
What does the deal comparison do?
It calculates two shopping scenarios independently and highlights which one produces the lower final total.
