VAT Calculator

Quickly add VAT to any net price for invoicing and quoting. Enter your price excluding VAT, select your rate (UK 20%, EU rates, or custom), and instantly see the VAT amount and final price including VAT. Perfect for business invoicing and retail pricing.

Calculate the net price from a VAT-inclusive amount. Enter the gross price and VAT rate to find the original price before VAT and the VAT portion. Essential for expense tracking, VAT reclaims, and analyzing competitor pricing.

Calculate VAT at UK rates: standard 20%, reduced 5%, and zero 0%. Our UK VAT calculator helps businesses with invoicing, expense tracking, and VAT returns. Includes guidance on which rate applies to different goods and services.

Simplify your business VAT calculations. Whether you're invoicing customers, reclaiming VAT on purchases, or preparing VAT returns, our business VAT calculator provides accurate results with step-by-step explanations for your records.

VAT (Value Added Tax) is a consumption tax charged on the value added at each stage of a product's supply chain, ultimately paid by the final consumer. Businesses collect it on sales (output VAT) and reclaim it on purchases (input VAT), remitting only the difference to the tax authority.

The mechanism is what makes VAT different from a simple markup. A manufacturer, wholesaler, and retailer each charge VAT but deduct the VAT they already paid, so tax is not compounded at every stage.

Key terms to understand:

• Net price — the amount before VAT, also called the VAT-exclusive price
• Gross price — the amount including VAT, what the consumer pays
• Output VAT — the tax a business charges its customers
• Input VAT — the tax a business pays on its own purchases, usually reclaimable

According to HMRC and the European Commission, this credit-invoice system is the standard model used across the UK and all EU member states.

To calculate VAT, first decide whether your figure is net or gross, enter it, choose the applicable rate, and read the net, VAT, and gross amounts instantly. The tool handles the arithmetic so you avoid manual rounding errors.

Worked example — adding VAT to a net invoice of 250 at a 20% rate:

• Step 1 — Select "Add VAT to price" as the calculation type
• Step 2 — Enter 250 as the amount (this is your net, VAT-exclusive figure)
• Step 3 — Choose the 20% rate, or type a custom rate for your country
• Step 4 — Read the result: VAT = 250 × 0.20 = 50, gross = 250 + 50 = 300

To reverse this, switch to "Remove VAT" and enter 300; the calculator divides by 1.20 to return the 250 net figure.

Always confirm the correct rate for your goods using current HMRC or your national tax authority guidance before issuing an invoice, since reduced and zero rates apply to specific categories.

To remove VAT from a gross price, divide by (1 + rate/100) — never subtract the percentage directly. For a 20% rate you divide by 1.20, so a 120 gross price yields a 100 net price and 20 of VAT.

The reason is mathematical: the 20% VAT was calculated on the smaller net figure, not the larger gross figure. Subtracting 20% of the gross (120 − 24 = 96) removes too much and understates your net price.

The correct reverse formula:

• Net = Gross ÷ (1 + Rate/100) — divide the total to strip VAT
• VAT = Gross × Rate ÷ (100 + Rate) — a shortcut for the VAT portion alone
• For 20%, the VAT fraction of any gross price is exactly 1/6

This matters for expense claims and VAT returns, where HMRC requires the correct VAT figure. Getting the reverse calculation wrong is one of the most common errors in bookkeeping.

The most common VAT mistake is subtracting the rate from a gross price instead of dividing, which produces a net figure that is too low. Because VAT compounds on the net base, only division reverses it correctly.

Watch for these frequent errors:

• Subtracting instead of dividing — 120 − 20% = 96 is wrong; 120 ÷ 1.20 = 100 is correct
• Applying the wrong rate — reduced and zero-rated goods differ from the standard rate; check current HMRC guidance
• Confusing net and gross — always confirm whether a quoted price already includes VAT
• Assuming VAT equals US sales tax — VAT is multi-stage and reclaimable, unlike single-point sales tax
• Rounding too early — round only the final figure, not intermediate steps

Another pitfall is treating exempt and zero-rated supplies as identical. They are not: zero-rated sales let a business reclaim input VAT, while exempt sales generally do not. When in doubt, verify with your national tax authority rather than guessing.

VAT, GST, and US sales tax are all consumption taxes, but VAT and GST are collected in stages and reclaimable by businesses, while US sales tax is charged only once at the final retail sale. The arithmetic in this calculator works for all three.

GST (Goods and Services Tax) is functionally the same as VAT and is used in countries such as Australia, Canada, India, and New Zealand. Only the name and rate differ; the credit-invoice mechanism is identical.

Key distinctions:

• VAT/GST — levied at each supply stage, with input tax reclaimable by registered businesses
• US sales tax — levied once at the point of final sale, set by individual states and localities, not the federal government
• Reclaim — VAT-registered firms recover input VAT; sales tax is generally a final cost to the buyer

Because US states set their own rates and rules, there is no single national sales tax rate in the United States. For cross-border digital sales, both the European Commission VAT rules and destination-based US state rules can apply, so verify the correct jurisdiction before charging.

The correct VAT rate depends on the country and the category of goods or services, not a single universal figure. The UK applies a standard rate, a reduced rate, and a zero rate, and each covers specific product classes defined by HMRC.

Broad categories to check:

• Standard rate — most goods and services (the UK standard rate is 20% for the current tax year; confirm on GOV.UK)
• Reduced rate — items such as domestic energy and children's car seats
• Zero rate — most food, books, and children's clothing in the UK
• Exempt — insurance, finance, and certain education and health services

Across the EU, standard rates vary by member state and are set nationally, so a sale into Germany, France, or Ireland may carry a different rate than a UK sale. Because governments can change these percentages, treat the dropdown values here as convenient presets and verify the live figure with HMRC or the European Commission before invoicing. This calculator accepts any custom rate so it stays accurate whenever rates are updated.

A small business must register for VAT once its taxable turnover exceeds the threshold set by its tax authority, after which it charges VAT on sales and reclaims VAT on eligible purchases. In the UK, the registration threshold is published by HMRC and reviewed periodically, so check the current figure rather than relying on a fixed number.

Once registered, the core obligations are straightforward:

• Charge output VAT on your sales at the correct rate for each product
• Record input VAT on business purchases so it can be reclaimed
• File VAT returns to your tax authority on the required schedule, paying the net difference
• Keep VAT invoices for the retention period HMRC specifies (several years)

Use this calculator to produce accurate line-item VAT figures for invoices and to check the net value of expenses when reclaiming input VAT, then feed those net amounts into our profit calculator to see the true margin on each sale. For scheme choices such as the Flat Rate or Cash Accounting schemes, and for the current threshold and filing frequency, consult GOV.UK or a qualified accountant, since the rules affect how much tax you actually owe.
