Value Added Tax (VAT) Calculator
Calculate Value Added Tax (VAT) instantly. Enter the net price of an item and the VAT rate to get the VAT amount and the gross price including VAT.
Calculate VAT Amount and Total Price Including VAT
Value Added Tax (VAT) Formula
Where:
- \(VAT\) — the amount of Value Added Tax to add to the price
- \(Price\) — the net price of the product or service, before VAT
- \(VAT\ Rate\) — the applicable VAT rate in percent (e.g., 20 for 20%)
The first formula gives the tax amount, and the second adds it to the net price to produce the gross price the customer actually pays.
Value Added Tax (VAT) – Calculation Example
Example: an item costs \(\$100\) before tax and the applicable VAT rate is \(15\%\).
\[ VAT = \frac{100 \times 15}{100} = \$15 \]
\[ Total\ Price = 100 + 15 = \$115 \]
Result: the VAT amount is \(\$15\) and the total price including VAT is \(\$115\).
How to Use the VAT Calculator
- Enter the net price of the item or service in the Price of Item (without VAT) field. This is the price before any tax is applied.
- Enter the applicable rate in the VAT Rate (%) field. You can use decimal values, for example 17.5 for a rate of 17.5%.
- Read the results: VAT shows the tax amount, and Total Price (including VAT) shows the gross price the customer pays.
What Is VAT and How Does It Work?
Value Added Tax (VAT) is a consumption tax charged on goods and services at each stage of production and distribution, wherever value is added. Businesses collect the tax on their sales (output VAT) and deduct the tax they paid on their purchases (input VAT), remitting only the difference to the tax authority. In practice, this means the tax is ultimately paid by the end consumer, while businesses act as collectors.
VAT is the standard consumption tax in more than 170 countries, including the United Kingdom, Germany, France, and most of Europe. Countries such as the United States use sales tax instead, which is applied only once, at the final sale to the consumer. Standard VAT rates vary widely — from 5% in some jurisdictions to 27% in Hungary — and many countries also apply reduced rates to essentials such as food, medicine, or books.
This calculator works in the most common direction: from a net (excluding VAT) price to a gross (including VAT) price. The result tells you two things at once — how much tax is added on top of your net price, and what the customer will actually see on the invoice or receipt. This is useful for pricing products, checking invoices, and reclaiming or reporting VAT correctly.
Extracting VAT from a Gross Price
Sometimes you know the gross (VAT-inclusive) price and need to work backwards. To find the net price, divide the gross price by \(1 + \frac{VAT\ Rate}{100}\):
\[ Net\ Price = \frac{Gross\ Price}{1 + \frac{VAT\ Rate}{100}} \]
The VAT amount is then the difference between the gross and net prices. For example, with a 20% rate, a gross price of \(\$120\) gives a net price of \(120 / 1.2 = \$100\) and VAT of \(\$20\). Note that VAT of 20% on a net price is not the same as 20% of a gross price — the two are frequently confused.
Common VAT Rates
Rates change over time and reduced rates apply to specific categories, so always confirm the current rate with your tax authority. The table below lists examples of standard rates.
| Country / Region | Standard VAT Rate |
|---|---|
| United Kingdom | 20% |
| Germany | 19% |
| France | 20% |
| Spain | 21% |
| Italy | 22% |
| Ireland | 23% |
| Hungary | 27% |
| Sweden | 25% |
| Australia (GST) | 10% |
| New Zealand (GST) | 15% |
Assumptions and Limitations
- The calculator applies a single VAT rate to the full price. It does not handle mixed-rate invoices where different items are taxed at different rates.
- It assumes the price you enter is net (excluding VAT). If your price already includes VAT, extract the net amount first using the reverse formula above.
- VAT registration thresholds, exemptions, and zero-rating rules vary by country and are not taken into account — the calculator simply applies the rate you enter.
- Rounding follows standard commercial practice: results are rounded to two decimal places. In some jurisdictions, legal rounding rules for VAT on invoices may differ slightly.
Practical Tips
- When pricing products, calculate the VAT on the net price, never add the percentage to the gross price.
- Keep net and gross amounts clearly separated on invoices — tax authorities usually require both, along with the rate and the tax amount.
- If you are assessing a business's overall financial health beyond tax, tools like the Earnings Before Interest and Taxes (EBIT) calculator or the Debtors Days calculator can help you analyze profitability and how quickly customers pay their invoices.
- For long-term planning, the Term Deposit calculator can show how your after-tax savings can grow at a fixed rate.
Frequently Asked Questions
How do I calculate VAT by hand without a calculator?
Multiply the net price by the rate as a decimal. For a 20% rate, that's simply multiplying by 0.2 — so £80 net gives £16 VAT and £96 gross. For awkward rates like 17.5%, break it down: 10% is 8, 5% is 4, 2.5% is 2, totaling £14 on an £80 item. Always apply the percentage to the net amount, then add it on top.
Is VAT the same as sales tax or GST?
They are all consumption taxes, but they work differently. VAT is collected at every stage of production, with businesses reclaiming tax paid on inputs; sales tax (used in the US) is charged only at the final sale. GST (Goods and Services Tax) in Australia, New Zealand, Canada, and India is structurally very similar to VAT — you can use this calculator for GST amounts by entering the GST rate.
What is a normal or good VAT rate?
There is no single "good" rate — standard rates are set by law and vary from around 5% to 27% across jurisdictions. Most European countries fall between 19% and 25%. Many nations also apply reduced rates (often 0–10%) to essentials like food, medicine, children's clothing, or books, and zero-rate certain goods entirely. Always check the current rate with your local tax authority.
Why does 20% VAT on a net price differ from taking 20% of a gross price?
This is a very common mistake. VAT is calculated on the net price, so 20% VAT on 100 is 120. If you instead take 20% of the gross 120, you get 24 — which is wrong. To extract VAT from a gross price, the tax fraction is rate ÷ (100 + rate): at 20% that's 20/120 = 16.67% of the gross amount, not 20%.
How do I handle invoices with items at different VAT rates?
Calculate each line separately at its own rate, then sum the results — a single percentage applied to the whole invoice will give the wrong answer. For example, a £100 item at 20% plus a £100 item at 5% has £25 total VAT, not £23.75 or £30. This calculator applies one rate per calculation, so run it once per rate group and add the amounts.
How should I round VAT amounts on invoices?
The standard commercial practice is rounding to two decimal places. However, some countries specify whether VAT is rounded per line item or on the invoice total, and whether rounding goes up, down, or to nearest. Small discrepancies (a cent or two) between your calculation and a supplier's invoice are usually just rounding differences, but check your local invoicing rules if you need compliance for tax filings.
Can VAT be 0%, and does that mean the item is exempt?
No — zero-rated and exempt are legally distinct. A zero-rated good (e.g., basic groceries or children's clothes in the UK) still counts as a taxable supply, so businesses can reclaim input VAT on related costs. An exempt supply (like certain financial services) means no VAT is charged and no input VAT can be reclaimed. For your calculations, a 0% rate simply means the gross price equals the net price.
