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.
Is this calculator free?
Yes, completely free. No account, no subscription, no hidden fees.
Is my data stored?
No. All calculations happen in your browser. Nothing is sent to any server.
Can I compare two deals?
Yes. Use comparison mode to enter two different price+discount combinations and see which gives you a better deal.
What is the discount table?
It shows the discounted price for your item at every 10% increment from 10% to 90% off, making it easy to evaluate different discount levels.
