Sales Tax Calculator
Add sales tax to a price, or find the pre-tax price from a total.
Sales tax turns a shelf price into a checkout total, and the rate varies widely by state, county and city — so a quick, accurate calculation matters whether you're budgeting a purchase, pricing a product, or reconciling a receipt. Sometimes you need the reverse: given a tax-inclusive total, what was the pre-tax price and how much was tax?
Enter a price and a tax rate to get the tax amount and the total. It's the fast companion for shopping, invoicing and expense tracking in any region with sales tax or VAT.
