VAT
Value-added tax (VAT) is a consumption tax charged on the value added to many goods and services. Businesses commonly show VAT separately on invoices and collect it for the relevant tax authority. The applicable treatment, rate, reporting obligations and invoice details depend on the transaction and the rules of the relevant jurisdiction.
Why this matters when you invoice
Separating net, VAT and gross amounts helps a customer understand the charge and helps the seller preserve the information needed for their records.
Where it appears on an invoice
Where VAT applies, an invoice commonly shows the taxable amount, VAT rate, VAT amount and total. Some transactions also require a VAT identifier or specific wording.
VAT arithmetic example
A seller has confirmed that a 20% rate applies to a net amount of €500. The VAT arithmetic is €100, producing a gross total of €600. The example illustrates the calculation; it does not establish that 20% is the correct rate for a real transaction.
Common mistakes
- Choosing a familiar rate without checking the actual transaction.
- Treating VAT arithmetic as a decision about tax treatment.
- Omitting required identifiers or transaction-specific wording.
Put it into practice
Enter the rate you have confirmed, then use the calculator to separate net, VAT and gross amounts.
InvoiceCraftly does not determine the correct VAT rate or tax treatment. Confirm the treatment and rate that apply to the transaction before using the result.

Does the VAT calculator choose a rate?
No. You enter the rate that applies; the calculator only performs the arithmetic.
