Frequently Asked Questions
How is the final price calculated with both discount and sales tax?
The discount is applied first to find the discounted subtotal: Price × (1 – Discount/100). Sales tax is then added to that discounted amount.
Can I compute stacked or sequential discounts?
You can input multiple sequential percentages to see the compounded effect on the final receipt.
