Final price includes sales tax applied to the discounted sale price, not the original price.
How the Discount Calculator Works
This calculator finds how much you save on a purchase, whether the discount is given as a percentage off or a fixed dollar amount, and optionally applies sales tax to the discounted price.
Formula
Sale Price = Original Price − Discount Amount
Final Price = Sale Price × (1 + Tax % / 100)
Frequently Asked Questions
How do I calculate a percentage discount?
Multiply the original price by the discount percentage divided by 100 to get the discount amount, then subtract that from the original price to get the sale price.
Is sales tax applied before or after the discount?
In most jurisdictions, sales tax is applied to the discounted sale price, not the original price. This calculator follows that convention.
Can I enter a fixed dollar discount instead of a percentage?
Yes, switch the discount type toggle to "Fixed Amount Off" and enter the dollar amount being taken off the original price.
