Discount = Price × (Discount % ÷ 100). Final Price = (Price − Discount) × (1 + Sales Tax %).
Example
Example: an $80 item with a 20% discount drops to $64, then 7% sales tax adds $4.48 — for a final price of $68.48.
Frequently Asked Questions
Is sales tax applied before or after the discount?
In almost all US states, sales tax is calculated on the discounted price, not the original price — this calculator follows that standard order.
Does this work for stacked discounts?
For a second discount, apply it to the "Price After Discount" figure as a new starting price rather than adding the percentages together.
