How it works
Multiply the pre-tax price by the tax rate to get the tax, then add it back to reach the total. To work backwards from a tax-included total, divide by one plus the rate to recover the pre-tax amount.
Frequently asked questions
Is US sales tax the same everywhere?⌄
No. There is no national sales tax; rates are set by states and localities and commonly range from 0% to over 10% combined. A few states have no statewide sales tax at all.
What's the difference between sales tax and VAT?⌄
Sales tax is charged once, at the final sale to the consumer. VAT is collected in stages across the supply chain and is used in most countries outside the US.
How do I find the tax portion of a total price?⌄
Divide the total by one plus the tax rate to get the pre-tax amount, then subtract that from the total to isolate the tax.
