What Is VAT and How Is It Calculated?

VAT (Value Added Tax) is a consumption tax charged on most goods and services in over 160 countries. To calculate VAT, you multiply the net price by the VAT rate. A product priced at £100 net with a 20% VAT rate has £20 in VAT, making the gross price £120. To remove VAT from a gross price, you divide by 1 plus the rate as a decimal: £120 / 1.20 gives £100 net.

The calculator above adds VAT to a net price or extracts VAT from a gross price for any country. It comes with preset rates for the UK, Ireland, France, Germany, Italy, Spain, and most EU member states, plus a custom rate option for any other jurisdiction. Switch the mode to flip between adding and removing VAT, and check the country rates tab for a quick reference table.

How to Calculate VAT in the UK

The UK standard VAT rate is 20%, in place since 4 January 2011. There is also a reduced rate of 5% (applied to domestic energy, children's car seats, and some renovation work) and a zero rate that covers most food, books, newspapers, and children's clothing.

To calculate UK VAT on a net amount, multiply by 0.20 to get the VAT and by 1.20 to get the gross. For a £500 net invoice the VAT is £100 and the gross is £600. Working backwards from a gross figure, divide by 1.20 to find the net (£600 / 1.20 = £500), then subtract to find the VAT (£600 − £500 = £100). The same UK VAT calculator above handles both directions in one click.

HMRC requires VAT-registered businesses to charge VAT on all standard-rated sales, file quarterly VAT returns through Making Tax Digital, and keep digital records for at least six years. Businesses with turnover below £90,000 (the 2024 threshold) are not required to register, although they may register voluntarily to reclaim input VAT on their own purchases.

How Do You Calculate VAT to Add to a Net Price?

Adding VAT to a net price uses one multiplication: Gross = Net × (1 + Rate/100). For 20% VAT the multiplier is 1.20. For 23% (Ireland) the multiplier is 1.23. For 19% (Germany) it is 1.19.

Worked example: a freelancer in the UK invoices a client £2,400 plus VAT. The VAT is £2,400 × 0.20 = £480. The total invoice is £2,400 + £480 = £2,880. The freelancer collects this £480 from the client and pays it to HMRC at the end of the VAT quarter, after subtracting any input VAT they paid on business expenses.

To calculate the VAT amount on its own (without the gross), use VAT = Net × (Rate / 100). The output cards in the calculator show all three values together: net, VAT amount, and gross.

How to Remove VAT from a Gross Price

Removing VAT from a gross figure (also called extracting or backing out VAT) uses division: Net = Gross / (1 + Rate/100). The VAT amount is then Gross minus Net.

The most common mistake is to subtract the VAT percentage from the gross price. With a 20% rate, the gross is 120% of the net, so the net is 100/120 = 83.33% of the gross, not 80%. If you simply subtract 20% from £120 you get £96, which is wrong. The correct net is £100.

Quick UK shortcut: divide the gross by 6 to find the VAT, then subtract from the gross to find the net. £120 / 6 = £20 VAT, leaving £100 net. This shortcut works only at the 20% rate.

VAT Rates in the UK, Ireland, and Across Europe

VAT rates differ widely by country. The standard rate ranges from 17% (Luxembourg) to 27% (Hungary) across the EU. Here is a comparison of the most-searched countries:

The country selector in the calculator switches between these rates instantly. Reduced rates apply to specific categories such as food, books, hotel accommodation, transport, and certain energy products. The applicable rate depends on the goods or service, not the country alone.

How Does the VAT Refund Work for Tourists?

Non-EU residents can claim back the VAT paid on goods purchased in EU countries and taken home in personal luggage. The refund process applies to physical goods only, not services, hotel stays, or restaurant bills.

Each country sets a minimum spend per receipt. France requires €100.01 in a single store on the same day. Italy has a €70.01 minimum, Germany asks for €25, and Spain has no minimum at all. The shop issues a tax-free form, which must be stamped by customs at the point of departure from the EU. Refund operators such as Global Blue and Planet Tax Free then process the claim, typically returning 60% to 80% of the VAT paid after their commission.

The United Kingdom abolished its tourist VAT refund scheme on 1 January 2021. Visitors can no longer reclaim VAT on items bought in UK shops and taken home, although goods shipped abroad directly by the retailer may still qualify for zero-rating.

Italy VAT refund and France VAT refund calculations are the most-searched of these schemes because both countries have major luxury retail markets. The refund estimator tab in the calculator above shows the expected return after operator fees, based on the country and purchase amount you enter. Actual refunds vary by retailer, operator agreement, and how you choose to receive the money (cash usually pays less than card or bank transfer).

What Is the UK Flat Rate VAT Scheme?

The Flat Rate Scheme is an alternative VAT accounting method available to UK businesses with annual VAT-taxable turnover below £150,000. Instead of tracking input and output VAT separately, the business pays a fixed percentage of its gross (VAT-inclusive) turnover to HMRC.

The flat percentage depends on the trade. A computer consultant pays 14.5%. A hairdresser pays 13%. A writer or publisher pays 12.5%. Businesses classified as a "limited cost trader" (those spending less than 2% of turnover on goods) pay 16.5% regardless of trade. The scheme reduces paperwork and bookkeeping, but usually means the business cannot reclaim VAT on most purchases.

Worked example: a consultant invoices £100,000 plus 20% VAT (so £120,000 gross) over a year, on the 14.5% flat rate. The business pays £120,000 × 0.145 = £17,400 to HMRC, instead of working out actual input and output VAT every quarter. Whether this saves money depends on how much VAT the business would otherwise reclaim on expenses. A separate flat rate VAT calculator can compare the two methods side by side.

Common VAT Calculation Mistakes

The single most common VAT error is treating the rate as a flat percentage of the gross price. As shown in the "remove VAT" section, subtracting 20% from a 20%-VAT gross gives the wrong net by about 4%. Always divide by 1.20 (or whatever the rate plus 1 is) instead.

Another frequent slip is mixing up gross and net when issuing an invoice. Software defaults vary, so check whether the price you typed is the net (before VAT) or the total (after VAT) before sending. Most accounting tools display both columns to remove ambiguity.

Rounding errors also accumulate when invoices have many line items. HMRC and most EU tax authorities allow line-item rounding to the nearest penny or cent, but a long invoice with dozens of small lines can produce a total that differs from the simple "net total × 1.20" by a few cents. The tax authorities accept either method as long as it is applied consistently.

VAT, Sales Tax, and GST

VAT, sales tax (used in the United States), and GST (used in Australia, New Zealand, India, Singapore, Canada, and others) all add a percentage to the price of goods and services, but they collect the tax differently. VAT and GST are charged at every stage of the supply chain, with each business in the chain reclaiming the tax it paid on its own inputs. Sales tax is typically charged only at the final sale to the consumer.

The end-customer pays a similar amount under either system, but VAT spreads the collection across multiple businesses while sales tax concentrates it at the retail point. For practical calculation, the calculator works the same way for VAT, GST, and sales tax: pick "Custom rate" in the country dropdown and enter the percentage that applies in your jurisdiction. The math is identical: gross equals net multiplied by (1 plus the rate divided by 100).
