Frequently Asked Questions

How do stacked discounts (e.g., 30% off plus extra 10% off) work?
Stacked discounts apply sequentially rather than additively. A 30% discount is applied first to the original price, and the additional 10% is calculated on the remaining reduced amount, yielding a 37% total discount.
How do I calculate the percentage off from the original and final price?
Formula: Percentage Off = [(Original Price - Final Price) / Original Price] * 100. Our calculator can reverse-calculate the discount percentage if you know both prices.
Can this tool calculate fixed dollar discounts as well as percentages?
Yes. You can toggle between percentage off (e.g. 25% off) and fixed dollar deductions (e.g. $15 off voucher) to determine your final cost.
Does this calculator include sales tax?
You can optionally enter your local sales tax percentage to calculate the exact total price you will pay at checkout after the discount is applied.
Is this Discount Calculator free to use on smartphones?
Yes, 100% free with a mobile-optimized layout that loads instantly on any iPhone or Android web browser without app downloads.
