How the vat calculator works
For net prices, VAT = amount × rate. For gross prices, net = total ÷ (1 + rate), and VAT is the difference.
Check your measurements and assumptions
VAT rates, exemptions, invoice rules and rounding vary by country and product. Enter the applicable rate and confirm local requirements.
Review the estimate before you act
Compare this result with an independent measurement, supplier quote or institution guidance when the decision matters. Confirm that the units and assumptions match the labels above, and update the inputs when the conditions change. Keep a note of the values used so you can reproduce the estimate later. This calculator is a planning aid and does not replace professional, product-specific or local guidance.
How do I remove VAT from a price?
Divide the VAT-inclusive total by one plus the VAT rate as a decimal; subtract the net amount to find VAT.
