How the sum works

Adding VAT

Got an amount excluding VAT? Multiply it by 1.21 and you have the amount including 21% VAT. The difference between the two is the VAT.

Working VAT back out

Got only the amount including VAT? Divide it by 1.21 and you have the amount excluding 21% VAT. What comes off is the VAT.

Careful: subtracting 21% from that amount gives an answer that is too low. The VAT was calculated over the amount excluding VAT, not over the amount including it.

The VAT rates

Per rate you see what to multiply by to add the VAT, and what to divide by to work it back out.

Round per rate, over the total

Does your invoice have several lines? Then you calculate the VAT per rate over the summed subtotal, and round to whole cents after that. Rounding per line first and adding those amounts up can differ by a cent. This calculator works the same way, and so does factuurmaken on your invoice.
