Frequently Asked Questions

How do stacked discounts work? ▼

Stacked discounts apply sequentially. For example, 20% off then 10% off on $100: first $100 → $80, then $80 → $72. This is NOT the same as 30% off ($70).

Can I add tax after the discount? ▼

Yes. Enter a tax rate and the calculator will show the final price including tax after the discount is applied.

What is Buy X Get Y? ▼

Enter the total items you are buying and how many are free. The calculator shows the effective discount percentage.
