Why use VAT Calculator?

VAT (Value Added Tax) in the UK is charged at one of three headline rates: 20% standard, 5% reduced, or 0% zero-rated, depending on the good or service. This calculator handles the arithmetic in both directions. Forward mode answers "what does a £250 net price cost with VAT added?" Reverse mode answers "how much of this £108 total is VAT?", useful when a receipt or supplier invoice only shows the VAT-inclusive total. Both modes use the same selected rate, round to the nearest penny, and update instantly as you change the amount, rate, or mode, so it works equally well for pricing a product, checking an invoice, or sanity-checking a quote. Because which rate applies is a product-classification question rather than a math one, the calculator lets you pick the rate directly rather than guessing it, check HMRC's guidance if you're unsure which rate a specific good or service falls under. For US sales tax instead, see our sales tax calculator.

Frequently asked questions

What is the current UK VAT rate?

The standard rate is 20%, covering most goods and services. A 5% reduced rate applies to specific items like home energy and children's car seats, and a 0% zero rate applies to most food, books, newspapers, and children's clothes.

How do I remove VAT from a price?

Use "Extract VAT from a gross price" mode. The tool divides the gross amount by 1 plus the VAT rate (1.20 for the standard rate) to find the net price, then the VAT amount is the difference between the gross and net figures.

How do I know which VAT rate applies to what I'm selling?

It depends on the specific good or service, not the price, and HMRC publishes detailed category guidance. This calculator does the arithmetic once you know the rate; it doesn't classify products.

Is this the same as sales tax?

The math is similar, add or extract a percentage, but VAT is a UK/EU-style tax typically included in the displayed price, while US sales tax is usually added at checkout. Use our sales tax calculator for US state and local rates.

Does this calculator submit anything to HMRC?

No. It's a plain arithmetic tool that runs in your browser. Nothing you enter is sent anywhere, and it isn't a substitute for VAT registration or filing software.
