VAT Calculator

Value Added Tax, or VAT, is a consumption tax applied at each stage of a product's sale in most countries outside the United States, and it shows up everywhere from restaurant receipts to business invoices to online checkout pages. The tricky part isn't the concept, it's the arithmetic: adding VAT to a price uses one formula, and pulling VAT back out of a price that already includes it uses a different one, and mixing the two up produces a wrong number every time.

This VAT calculator is built for small business owners pricing products or writing invoices, freelancers who need to quote clients a price with or without tax, shoppers trying to figure out the pre-tax cost of something, and anyone doing bookkeeping who needs to split a gross receipt total into its net and tax components. It handles both directions, adding VAT to a net price and removing VAT from a gross price, at any rate you enter.

VAT rates vary widely by country and even by product category within a country, so rather than hardcoding one rate, this tool lets you pick from common preset rates or enter any custom percentage, which means it works for VAT in the EU and UK, GST in Australia, and any other percentage-based sales tax or value-added tax system worldwide.

Adding VAT to a net (pre-tax) price uses this formula: Gross Price = Net Price × (1 + VAT rate). For a $100 net price with 20% VAT, that's $100 × 1.20 = $120 gross. The VAT amount itself is simply the gross price minus the net price, or $20 in this example. This is the calculation a business does when setting a shelf price or invoice total from a known net cost.

Removing VAT from a gross (tax-inclusive) price works differently, and this is where manual calculations most often go wrong: Net Price = Gross Price ÷ (1 + VAT rate). For a $120 gross price at 20% VAT, the net price is $120 ÷ 1.20 = $100, not $120 minus 20% of $120 (which would incorrectly give $96). The VAT amount is then the gross price minus that net price, or $20.

The reason simply subtracting a percentage doesn't work when removing VAT is that the 20% in a VAT-inclusive price is 20% of the original net amount, not 20% of the gross total you're starting from. Since the net amount is smaller than the gross amount, taking 20% of the larger gross figure overstates the tax and understates the true net price. This calculator applies the correct divide-based formula automatically in its "Remove VAT" mode.

• Add VAT: Gross = Net × (1 + rate) — e.g. $100 × 1.20 = $120 at 20% VAT
• Remove VAT: Net = Gross ÷ (1 + rate) — e.g. $120 ÷ 1.20 = $100 at 20% VAT
• VAT amount = Gross − Net either way
• Never subtract the VAT percentage directly from a gross price; it overstates the tax

Standard VAT rates vary significantly by country: the UK charges 20%, Germany charges 19%, France charges 20%, and the Netherlands charges 21%. Israel applies an 18% VAT on most goods and services. In the Gulf region, the UAE charges a 5% VAT, one of the lowest rates globally. Outside VAT systems specifically, Australia uses a 10% Goods and Services Tax (GST), which functions the same way mathematically even though it isn't called VAT.

Many countries also apply reduced VAT rates to specific categories, like food, books, or children's clothing, alongside their standard rate; the UK, for example, applies 0% to most food and 5% to domestic energy alongside its 20% standard rate. This calculator's preset buttons cover the most common standard rates (5%, 10%, 15%, 20%, 21%, 23%, 25%), and the custom rate field handles any other percentage, including Israel's 18% or a country-specific reduced rate.

Because rates and rules change and vary by product category and country, always confirm the exact applicable rate for your specific transaction with an official source or accountant rather than assuming a country's headline rate applies uniformly to everything sold there.

A compliant VAT invoice typically needs to show all three figures clearly: the net price (the amount before tax, which is the seller's actual revenue for goods/services), the VAT amount (the tax being collected on behalf of the government), and the gross price (the total the customer actually pays). This calculator displays all three simultaneously, whichever direction you're calculating from, making it straightforward to pull the numbers you need directly onto an invoice.

For a freelancer or small business, working in the "Add VAT" direction is typical when quoting a price, you know your net rate for the work and need to add the applicable VAT to invoice the client correctly. Working in the "Remove VAT" direction is more common when reconciling receipts or expenses, since a purchase receipt shows the gross amount paid and you need the net cost for expense reporting or reclaiming input VAT.

In a standard VAT system, VAT-registered businesses charge VAT on their sales (called output tax) and pay VAT on their own business purchases (called input tax). At the end of a filing period, the business pays the government the difference between output tax collected and input tax paid, or receives a refund if input tax exceeded output tax. This calculator helps with the arithmetic on each individual transaction, splitting a price into net and VAT components, but it doesn't track running totals or file returns.

For a purchase receipt showing only a gross total, use the "Remove VAT" mode to find the net cost and the VAT amount paid, which is the figure typically needed when claiming input VAT back or recording the correct pre-tax expense in bookkeeping software.

Scenario 1, pricing a product: a business wants to sell a product for a $50 net price in a country with 21% VAT. Using the Add VAT mode: $50 × 1.21 = $60.50 gross price, with $10.50 in VAT. Scenario 2, reading a receipt: a $60.50 receipt total at the same 21% rate breaks down (Remove VAT mode) to a $50 net cost and $10.50 in VAT, confirming the two directions are exact inverses of each other.

Scenario 3, comparing net prices across VAT rates: the same $100 net price results in a $118 gross total in Israel (18% VAT) versus a $121 gross total in the Netherlands (21% VAT), a $3 difference driven entirely by the different tax rate applied to an identical underlying price. This kind of comparison is useful when pricing the same product for customers in different countries.
