Calculate a discounted price with tax
A discount reduces the original price first. When you enter a sales tax percentage, this form applies it to the discounted price. It shows the saving and final amount separately.
For an original price of 100, a 20% discount and 10% tax, the discounted price is 80 and the final price is 88. Check whether your actual purchase follows this tax treatment.
