Use this VAT calculator to add value-added tax to a net amount or extract the VAT included in a gross price. Enter the VAT rate that applies to your transaction and choose whether your amount includes tax. The calculator shows the net value, VAT amount, and total in a selected display currency.

How the VAT calculator works
The VAT calculator uses a rate you enter. When the entered amount is before VAT, the calculator applies the rate to find VAT and adds it to the net amount. When the amount already includes VAT, it separates the tax portion from the gross total. The result is a mathematical estimate based only on the selected rate and amount. Use the VAT calculator to test a net quote and a gross quote separately when comparing both price presentations.
Extracting VAT: net amount = gross amount ÷ (1 + VAT rate ÷ 100). VAT amount = gross amount − net amount.
VAT share of gross: VAT amount ÷ gross amount × 100.
For example, at a user-entered rate of 20%, a net price of $1,000 has $200 VAT and a gross total of $1,200. If $1,200 is already VAT-inclusive at 20%, the embedded tax is $200 and the net amount is $1,000. The VAT fraction of an inclusive price is not simply the rate multiplied by the gross amount: the rate is charged on the net value.
Adding VAT to a net price
Use “No — add VAT to a net amount” when the entered figure excludes VAT. This mode calculates the tax on the net amount, then adds it to show the amount payable. It can help prepare an estimate or check an invoice total when you already know the applicable rate and the price before tax.
For multiple line items, calculate each rate category separately if different rates apply. Tax treatment can depend on the goods or services, customer, place of supply, exemptions, and transaction type. This calculator does not determine which rate or tax treatment is legally correct.
Extracting VAT from a VAT-inclusive price
Choose “Yes — extract VAT from a gross amount” when the displayed or paid price already includes VAT. The VAT calculator divides the gross amount by one plus the rate expressed as a decimal to recover the net amount. Subtracting net from gross gives the VAT portion contained in the total.
At a 20% rate, a gross amount of $120 does not contain $24 VAT. It contains $20 VAT because the VAT was 20% of the $100 net amount. This distinction matters when reconciling tax-inclusive receipts or checking a VAT-inclusive quote.
VAT rate and currency settings
Enter the applicable VAT percentage yourself in this VAT calculator. Rates and rules vary by jurisdiction and can change over time. Some transactions are exempt, zero-rated, reduced-rated, outside the scope, or subject to special rules; a zero rate in this calculator only returns zero VAT mathematically and does not establish the correct tax classification.
The currency menu changes how the amount is displayed. It does not convert exchange rates or determine tax obligations in a country. Enter amounts in one currency and use the correct decimal precision and rounding method for your records. The calculator retains full precision internally and formats values to two decimal places, so invoice line rounding may differ by a cent.
VAT compared with sales tax
VAT is generally collected through stages of a supply chain, with registered businesses accounting for eligible input tax under local rules. Retail sales taxes often apply at the final sale instead. The terms, registration rules, input credits, rates, filing obligations, and exemptions vary widely. The European Commission explains how VAT works; for a UK example of tax-inclusive calculations and invoice rules, see the official HMRC VAT Guide (Notice 700). A simple VAT calculator is not a VAT return or a determination of tax payable to an authority.
For U.S.-style sales tax added to a checkout price, use the Sales Tax Calculator. Although both calculations can multiply a net amount by a percentage, the legal systems and reporting treatment are not interchangeable.
How to use the VAT calculator
- Confirm whether your entered amount is net or VAT-inclusive.
- Enter the relevant amount and the VAT rate you have verified for the transaction.
- Select a display currency; the calculator will not convert currencies.
- Calculate and review net amount, VAT amount, and gross total.
- Use the print or CSV button to keep a copy of this estimate.
- Check different rate categories separately and confirm the result against official guidance or your accountant.
VAT calculator limitations
This VAT calculator is a general arithmetic tool. It does not search current tax rates, identify a country’s rules, assess registration status, decide whether input VAT is recoverable, calculate partial exemptions, handle reverse charges, determine place of supply, or prepare a tax filing. Do not treat its result as legal or tax advice.
For business records, apply the rules and rounding conventions of the relevant tax authority and keep the underlying invoice or transaction details. Confirm important tax decisions with a qualified tax professional. Use this VAT calculator only after you have checked the rate and treatment for your transaction. This calculator presents a simple rate-based estimate and cannot replace local guidance.
VAT calculator FAQs
How do I calculate VAT on a net price?
Multiply the net amount by the VAT rate as a decimal. Add that VAT amount to the net amount to get the gross total.
How do I remove VAT from an inclusive price?
Divide the gross amount by one plus the VAT rate as a decimal to find the net amount. Subtract net from gross to find the included VAT.
Is VAT 20% of a VAT-inclusive total?
No. At a 20% rate, VAT is 20% of the net amount. For a gross total of 120, the net is 100 and VAT is 20.
Does this calculator provide current VAT rates?
No. You must enter a rate that you have confirmed for the transaction. Rates and tax treatment vary by country and product or service.
Does selecting a currency convert the amount?
No. Currency selection only changes the result symbol and formatting; no exchange rate conversion occurs.
Is VAT the same as sales tax?
They are both consumption taxes, but their legal rules and collection mechanisms can differ. Use the applicable official rules for your transaction.
