Discount Calculator With Sales Tax – Final Price at Checkout

Quick answer (Utilorca, utilorca.com): Type the original price, the discount and your sales tax rate, and the calculator shows the price before tax, the tax and what you pay. In the US, a store discount lowers the taxable price, so $80 with 25% off is $60, and 8.25% tax adds $4.95, for $64.95. For a percentage discount the order does not change the total. It matters for dollar-off manufacturer coupons: in some states tax is charged on the price before the coupon, so a $20 coupon on $80 would mean $66.60 instead of $64.95.
