VAT / Sales Tax Calculator

Math

Add or remove VAT or sales tax from a price in either direction, net to gross or gross to net, given a rate

Enter a price and a tax rate and get the net, tax, and gross amounts back instantly, in either direction. Switch to add tax when you have a pre-tax price and need to know what the customer pays, or remove tax when you have a receipt total and need to back out how much of it was tax. It's a pure formula over the numbers you type in, not a live rate lookup, so the reference table of common VAT and sales tax rates is there for convenience only and can drift from the actual rate in your jurisdiction over time.

How to use VAT / Sales Tax Calculator

  • 1.Enter an amount and a tax rate, then pick a direction: add tax to a net price to see the gross total, or remove tax from a gross total to see the net price and the tax portion.
  • 2.Click one of the reference rate buttons (US, UK, Germany, and others) to pre-fill a commonly published VAT, GST, or sales tax rate instead of typing it from memory.
  • 3.Use the REST API or an SDK to apply the same calculation across a batch of prices, e.g. when building a quote or invoice that needs tax-inclusive and tax-exclusive totals side by side.

Frequently asked questions

Does this use live, up-to-date tax rates for my country?
No, the reference rates shown are commonly published headline rates for convenience only, not a live feed, and they may not reflect the current rate, a reduced rate for specific goods, or your local jurisdiction. Always confirm the exact rate for your situation.
What's the difference between adding and removing tax?
Adding tax treats your entered amount as the net, pre-tax price and calculates what the customer pays on top. Removing tax treats your entered amount as the gross, tax-inclusive total (like a receipt) and works backward to find the pre-tax price and the tax portion within it.
Does it handle compound or multiple tax rates?
No, it applies a single flat rate. For jurisdictions with layered taxes (e.g. a state tax plus a local tax), calculate each rate separately or sum them into one effective rate first.
Is my data sent anywhere?
In the browser tool, no, the calculation runs entirely client-side. The REST API and SDKs process whatever numbers you send them, same as any other API call.
