Frequently Asked Questions
What is the average US sales tax?
The average combined state and local sales tax in the US is about 6.6%, but ranges from 0% (Oregon, Montana) to over 10% in some cities.
How do I calculate tax backwards from the total?
Pre-tax price = Total ÷ (1 + Tax Rate/100). Example: $108 total at 8% tax → $108 ÷ 1.08 = $100.
What is VAT?
Value Added Tax (VAT) is a consumption tax used in most countries outside the US. It works similarly to sales tax but is typically included in the displayed price.
