Shopping math is trickier than it looks because a discount and sales tax apply in a specific order: the discount comes off first, then tax is charged on the reduced price. This calculator does both correctly in one step. Enter the original price, the discount percentage, and your sales tax rate, and it shows the discounted price, the amount you saved, the tax added, and the final total you actually pay at checkout. It is perfect for checking a sale in the store, comparing coupon offers, or figuring out whether a deal really beats the sticker price once tax is factored in. Set the tax rate to zero if your purchase is tax free. All numbers are computed instantly in your browser, so you can crunch a deal on your phone without any app.
The tool applies the percent discount to the price first, then adds sales tax to the discounted amount for the final checkout price.
It also shows the amount you saved from the discount and the sales tax charged on the reduced price.
Taxing after the discount is the standard checkout method, and it results in less tax than taxing the full pre discount price.
