Calculating VAT amount
This tool calculates a tax amount from a pre-tax price and a VAT rate that you enter, and it can show the total after tax. The page does not assume one rate applies to every country, item, or period.
Inputs and field meanings
Review these values before running the tool. The labels below come from the actual form so the guidance matches what you will use on this page.
- Price before VAT: required, minimum 0.
- VAT rate: required, minimum 0, maximum 100.
Calculation method
VAT amount = pre-tax price × VAT rate ÷ 100.
Total after VAT = pre-tax price + VAT amount. If the price you have already includes VAT, extracting the tax from that total requires a different formula or an inclusive-price mode.
Teaching example
For a pre-tax price of 200 and an entered rate of 15%, VAT is 30 and the total is 230. The 15% rate is only an example input, not a statement that it applies to every transaction.
Checks before relying on the number
- Confirm whether the entered price is tax-exclusive or tax-inclusive.
- Verify the rate applicable to the item, place, and period from an official source when the result will be used formally.
- Invoice rounding can follow specific accounting or legal rules, so compare with the actual invoice when available.
VAT questions
Does the calculator assume a fixed VAT rate?
No. The rate is an input, and the user should verify the rate that applies to the specific case.
Can I extract VAT from a tax-inclusive price?
That requires a different formula from multiplying the total by the rate. Use an inclusive-price calculator or mode when available.
Why can an invoice differ slightly from the result?
Rounding, line-item treatment, or local invoicing rules can create small differences.
