How to Calculate VAT — Add and Remove Tax

VAT (Value Added Tax) is a consumption tax used in over 160 countries. Business owners need to charge the correct VAT on invoices, consumers want to know how much tax they're paying, and accountants need to separate gross prices into net and VAT components for bookkeeping. This calculator handles all three scenarios instantly.

Whether you're invoicing a client in the UK (20%), calculating price comparisons in Europe (17–27%), or working with US sales tax in specific states, the rate input accepts any percentage. The preset buttons cover the most common EU and international rates.

VAT Formulas

Adding VAT: Gross = Net × (1 + rate/100)
Example: £100 net + 20% VAT = £100 × 1.20 = £120 gross (VAT = £20)

Removing VAT (de-vatting): Net = Gross / (1 + rate/100)
Example: £120 gross ÷ 1.20 = £100 net (VAT embedded = £20)

Common VAT Rates

UK: 20% standard, 5% reduced | EU range: 17–27% | US: 0–10.25% (sales tax) | Australia GST: 10% | Canada GST: 5%

When to Use This Calculator

Use the VAT calculator any time you need to convert between net (ex-VAT) and gross (inc-VAT) prices, verify the tax on an invoice, or set customer-facing prices that include VAT. It's essential for business owners, freelancers, and accountants working across VAT-registered transactions.

  • Invoicing clients: Your service fee is £800 net. At 20% UK VAT: £800 × 1.20 = £960 gross. Your invoice shows £960 total with £160 VAT line item. You collect £960, remit £160 to HMRC, keep £800.
  • Shopping price comparison: A £299 item in one shop includes VAT at 20%. A £265 item in another is "ex-VAT." True comparison: £299 / 1.20 = £249.17 net vs. £265 net — the VAT-inclusive shop is cheaper.
  • Bookkeeping reconciliation: A supplier invoice shows a gross total of €4,320 with 20% VAT. Net = €4,320 / 1.20 = €3,600. VAT = €720. You can reclaim that €720 on your VAT return if your business is VAT-registered.
  • International pricing: When selling to B2B customers in other EU countries (intra-community supply), the transaction may be zero-rated. Use the calculator to verify net figures for your invoices.

Step-by-Step Example: Checking a Restaurant Receipt

A business lunch receipt shows a total of £87.60 including VAT. The restaurant applies 20% VAT on food and drink. To verify: Net = £87.60 / 1.20 = £73.00. VAT = £87.60 − £73.00 = £14.60. Cross-check: £73 × 0.20 = £14.60 ✓. Your company can reclaim £14.60 VAT on this expense. If some items (like children's food) are zero-rated, the receipt should break them out separately at 0% VAT.

VAT Calculator UK — Practical Examples for British Businesses

The UK standard VAT rate is 20%, with a reduced rate of 5% on domestic energy and some health products, and 0% on food, children's clothing, and books. Here are the most common scenarios where UK businesses and freelancers need to calculate VAT.

Example 1: UK Freelancer Invoicing a Client

You're a VAT-registered graphic designer charging £1,500 for a brand project. Your invoice must show: Net price £1,500 + VAT (20%) £300 = Gross total £1,800. You collect £1,800 from the client, remit £300 to HMRC at the end of the quarter, and keep £1,500. If your client is also VAT-registered, they can reclaim the £300 as input VAT on their next return.

Example 2: Removing VAT from a Gross Price (Reverse VAT)

You receive a supplier invoice for £4,800 including VAT. To find the net amount for your books: £4,800 / 1.20 = £4,000 net. VAT embedded = £800. Common mistake: some people subtract 20% from £4,800 (= £3,840), which is wrong. Always divide by 1.20 — not multiply by 0.80.

Example 3: Checking If You Need to Register for VAT

The UK VAT registration threshold is £90,000 taxable turnover in any 12-month rolling period (2024/25). If your annual revenue crosses this, you must register within 30 days. Once registered: you charge 20% VAT on your services, submit quarterly VAT returns to HMRC, and can reclaim VAT on business purchases. Use the calculator to project your gross invoicing at 20% VAT to see what your clients will actually pay.

Example 4: Reclaiming VAT on Business Expenses

As a VAT-registered business, you can reclaim input VAT on qualifying business purchases. Monthly expenses: laptop £1,200 gross, office supplies £240 gross, software £96 gross. VAT reclaimable: (£1,200 + £240 + £96) / 1.20 × 0.20 = £1,536 / 1.20 × 0.20 = £256 input VAT you can offset against what you owe HMRC. If you collected £2,000 VAT from clients that quarter, you remit only £2,000 − £256 = £1,744 net VAT.

Frequently Asked Questions

How do I add VAT to a price? ▼
Multiply the net (pre-tax) price by (1 + rate/100). At 20% VAT: Net × 1.20 = Gross. Example: £250 net → £250 × 1.20 = £300 gross. The £50 difference is the VAT amount. This is the amount you charge customers and later remit to the tax authority.
How do I remove VAT from a price? ▼
Divide the gross (tax-included) price by (1 + rate/100). At 20% VAT: Gross / 1.20 = Net. Example: £300 gross → £300 / 1.20 = £250 net. The VAT embedded in that price is £50. A common mistake is subtracting 20% from the gross — that gives the wrong answer (£300 × 0.80 = £240, not £250).
What is the difference between VAT and sales tax? ▼
VAT is collected at every stage of the supply chain — manufacturer, wholesaler, retailer — with each stage reclaiming the VAT they paid upstream. Sales tax is only collected at the final point of sale to the consumer. The end consumer pays the same total in both systems, but VAT creates a paper trail that helps combat tax evasion.
How do I calculate VAT backwards from a gross price? ▼
VAT amount = Gross price × rate / (100 + rate). At 20%: VAT = Gross × 20/120 = Gross × 1/6. Example: £180 gross at 20% → VAT = £180 × 20/120 = £30. Net = £150. This fraction method is quicker to calculate mentally than division for common rates.
What are common VAT rates in Europe? ▼
Standard EU VAT rates: Hungary 27%, Sweden/Denmark/Norway 25%, Croatia 25%, Finland 24%, Ireland/Poland 23%, Italy 22%, Spain 21%, Netherlands/Belgium 21%, France/UK 20%, Germany 19%, Luxembourg 17%. Most countries have reduced rates (5–15%) for food, medicine, books, and children's products.
Do I need to register for VAT? ▼
VAT registration thresholds vary by country. In the UK, you must register when taxable turnover exceeds £90,000 in a 12-month period (2024 threshold). In the EU, thresholds vary by country (typically €10,000–€85,000). Once registered, you charge VAT on sales, reclaim VAT on business purchases, and submit periodic VAT returns.
Can I reclaim VAT on business purchases? ▼
Yes — if your business is VAT-registered, you can reclaim input VAT (VAT you paid on business purchases) against output VAT (VAT you collected from customers). The net VAT is what you remit to the tax authority. Example: you collected £4,000 VAT from customers, paid £1,200 VAT on business expenses → you remit £2,800 net to HMRC. You cannot reclaim VAT on non-business purchases, entertainment expenses (in most countries), or purchases used for exempt activities. Keep valid VAT receipts for all reclaimed items.
How does VAT work for digital services sold internationally? ▼
Since 2015 (EU) and progressively worldwide, digital services are taxed at the buyer's location, not the seller's. If you sell digital products (SaaS, e-books, online courses) to EU consumers, you must charge VAT at the buyer's country rate — even if your business is outside the EU. The EU's OSS (One-Stop-Shop) scheme simplifies compliance: register once and report all EU sales in one return. For B2B sales, the reverse charge mechanism typically applies — the buyer accounts for VAT. Always verify current rules with a tax advisor as digital VAT rules continue to evolve globally.
