VAT calculator

Add VAT when the figure you have is the net price, the amount before tax, and you need the total to put on a quote or invoice. Remove VAT when the figure you have already includes tax, for example a supplier price or a till receipt, and you need to know the net portion and the tax portion separately.

It is the most common VAT mistake. If a gross price is 120 and the rate is 20%, you cannot just take 20% of 120, that gives 24, which is wrong. The 20% was added to the net amount, not the gross amount. The correct method is to divide the gross by 1.20, which gives a net of 100 and VAT of 20. Subtracting the rate from the gross always understates the net and overstates the tax.

Use the standard rate that applies where you trade. The country presets above cover some common standard rates, but rates and rules vary by country, and many countries also have reduced or zero rates for certain goods and services. Pick Custom and type the exact rate that applies to your work, and check your local tax rules if you are unsure.

They work the same way for this calculation. VAT (value added tax) and GST (goods and services tax) are both taxes added as a percentage of the price. The Add and Remove maths in this calculator is identical for both, so the calculator works whether your country calls it VAT or GST.

That depends on whether you are registered for VAT or GST, which is a country-specific question this calculator cannot answer. If you are registered, you generally show tax as a separate line. If you are not, you do not add it. Check your local rules or speak to an accountant to be certain.
