How sales tax and VAT are added

Sales tax (in the US) and VAT (across much of the world) are added on top of the net price as a percentage. This tool takes a net amount and a rate and shows the tax and the gross total. Enter your local rate — rates differ widely by country, state and sometimes city.

Working backwards from a gross price

If you already have a tax-inclusive price and need the net amount and the tax portion — common for invoices and expenses — you cannot just subtract the percentage. Use the Reverse VAT Calculator, which divides the gross by one plus the rate to recover the original net figure.

Where it's used

  • Adding local sales tax to a purchase to see the real checkout total
  • A small business computing the tax to collect on an invoice
  • Budgeting the true cost of a big purchase like electronics or furniture
  • Comparing out-the-door prices across cities or states with different rates
  • Backing the tax portion out of a tax-inclusive total

Real-world examples

  • Adding 8.25% sales tax to a $1,200 laptop for a $1,299 total
  • A shopper in a 6% state finding $50 of goods costs $53.00
  • A seller separating $7 of tax out of a $107 receipt at a 7% rate
  • Comparing a $500 purchase in a no-tax state versus a 9% city, where it costs $545

A bit of history

The first general, state-level retail sales tax in the United States was introduced by Mississippi in 1930, as states scrambled for revenue during the Great Depression when property-tax collections collapsed; within a decade about two dozen more states had followed.

Did you know?

Five US states, remembered by the acronym NOMAD, have no statewide sales tax: New Hampshire, Oregon, Montana, Alaska, and Delaware, though Alaska and Montana still allow some local sales taxes.

FAQ

What is the difference between sales tax and VAT?

Both add a percentage to a price. Sales tax is typically added once at the point of sale; VAT is collected in stages along the supply chain. For a simple "add tax to price" calculation, the math is the same.
