Add or Remove VAT From Any Price in One Step

Value Added Tax is one of the most widely used consumption taxes in the world, applied in the European Union, the United Kingdom, Canada, Australia, and more than 170 other countries in various forms. For businesses that register for VAT, for consumers comparing prices across VAT-inclusive and VAT-exclusive quotes, and for accountants working with invoices in both formats, calculating VAT accurately and quickly is a routine operational necessity. Our free VAT calculator handles both directions of this calculation instantly: enter a net price and a VAT rate to find the VAT amount and the gross price, or enter a VAT-inclusive gross price to extract the original net amount and the VAT component separately.

Understanding both directions—adding VAT to a net price and removing VAT from a gross price—is important because businesses and consumers encounter both formats regularly. Supplier invoices may quote prices excluding VAT with the tax listed separately. Retail prices may display the VAT-inclusive total. Getting the arithmetic exactly right matters for compliance, accurate bookkeeping, and simply understanding what you're paying or charging.

The Two VAT Calculations: Adding and Removing

Adding VAT to a net (ex-VAT) price is the more intuitive direction: you have a price before tax and you want to know the gross total the customer will pay. The formula is: Gross Price = Net Price × (1 + VAT Rate ÷ 100). At 20% VAT, a £500 net price becomes £500 × 1.20 = £600 gross. The VAT amount is the £100 difference.

Removing VAT from a gross (VAT-inclusive) price is less intuitive and the source of a common calculation error. Many people simply subtract the VAT percentage from the gross price—calculating 20% of £600 and subtracting £120 to get £480. This is wrong. The correct formula is: Net Price = Gross Price ÷ (1 + VAT Rate ÷ 100). At 20%, the correct calculation is £600 ÷ 1.20 = £500 net, and the VAT is £600 − £500 = £100. Subtracting 20% of the gross would give £480 instead of £500—a £20 understatement of the net price that compounds into significant bookkeeping errors at any meaningful transaction volume.

Our calculator handles both directions accurately. Enter your amount as a net price to add VAT, or as a gross price to strip it out—the tool returns all three figures (net amount, VAT amount, and gross amount) so you have the complete picture regardless of which direction you're working.

VAT Rates Around the World

VAT rates vary significantly by country and, in many countries, by product or service category. Understanding the applicable rate for your transaction is the essential first step before any VAT calculation.

European Union

EU member states are required to apply a minimum standard VAT rate of 15%, though in practice most countries set their standard rate considerably higher. The standard rates range from 17% in Luxembourg to 27% in Hungary, with most EU countries applying rates between 19% and 25%. Reduced rates—typically 5% to 10%—apply to specific categories including food, books, pharmaceuticals, and some services, with zero-rating applicable to certain exports and cross-border supplies.

United Kingdom

The UK applies a standard VAT rate of 20% on most goods and services, a reduced rate of 5% on certain categories (including home energy, children's car seats, and certain renovation services), and zero-rating on essentials including most food, children's clothing, and books. UK VAT registration is required for businesses whose taxable turnover exceeds the annual registration threshold, and registered businesses must file regular VAT returns accounting for VAT collected and input VAT claimed on business purchases.

Australia (GST)

Australia applies a Goods and Services Tax (GST) at a flat 10% rate. GST is effectively a value-added tax applied at each stage of the supply chain with input credits available to registered businesses. Fresh food, certain medical services, and some educational services are GST-free. The calculation mechanics are identical to VAT at a 10% rate—add 10% to a net price to find the GST-inclusive amount, or divide a GST-inclusive price by 1.10 to extract the net amount.

Canada (GST/HST)

Canada applies a 5% federal Goods and Services Tax (GST). Several provinces have harmonized their provincial sales tax with the federal GST to create a single Harmonized Sales Tax (HST) at combined rates of 13% to 15%, while other provinces apply the GST plus a separate provincial sales tax (PST) with rates varying by province.

VAT for Businesses: Input Tax, Output Tax, and Net Position

For VAT-registered businesses, the tax operates as a pass-through mechanism—you collect VAT on your sales (output tax) and reclaim VAT you've paid on your business purchases (input tax). The difference between output tax and input tax is remitted to the tax authority in your periodic VAT return. In periods where your input tax exceeds your output tax (common for businesses with significant capital investment or in certain export-heavy industries), you may be in a VAT refund position rather than a payment position.

This input/output structure is why VAT is considered administratively superior to a simple retail sales tax by most economists: each business in the supply chain only bears the VAT on its own value added, rather than cascading taxes on the full value of materials passed through multiple stages of production. For the end consumer, who cannot reclaim input VAT, the full rate applies to the final purchase price.

Accurate VAT calculation on every transaction is therefore not just a convenience for businesses—it's a compliance requirement. Overcharging VAT on invoices creates a liability to the tax authority regardless of whether you've collected it. Undercharging creates a revenue shortfall and potential penalties. Our calculator ensures the arithmetic is exact on every transaction.

Reverse VAT Calculation: Finding the Net Price in a VAT-Inclusive Quote

One of the most practically useful applications of our VAT calculator is for buyers and accountants who receive gross prices and need to extract the pre-VAT net amount for their own accounting records. Suppliers sometimes quote VAT-inclusive prices rather than itemizing net and VAT separately, particularly in consumer-facing retail contexts. To record the transaction correctly in your accounts, you need to split the gross amount into its net and VAT components.

Rather than attempting the division manually—especially on non-round amounts like €347.50 at 19% VAT—our tool delivers the net amount (€347.50 ÷ 1.19 = €292.02) and the VAT amount (€55.48) immediately and accurately. This reverse VAT extraction is a daily function for bookkeepers working with expense receipts, and having a reliable tool for it reduces error rates significantly compared to manual calculation on high volumes of transactions.

Always Free, Always Private

The VAT calculator runs entirely within your browser. No amounts, rates, or financial data you enter are transmitted to any server or stored anywhere. The tool is completely free with no account required and no usage limits. Use it for a single transaction check or work through a full day's invoices—the calculation is always instant and always accurate.
