When you create a quotation or an invoice, prices will get rounded. In this article, you'll find the rules we use in Teamleader.
Every price is rounded to 2 digits after the comma per line. This goes for the price incl. VAT as well as the price excl. VAT.
VAT is calculated per line and based on the total amount before it is rounded.
2222 articles of €0,001 each, 12% VAT
Amount excl VAT: 2222 * 0,001 = €2,222 -> rounded to €2,22
VAT amount: €2,222 (amount excl VAT before rounding is used) * 0,12 = €0,26664 -> rounded up to €0,27
Amount incl VAT: €2,22 + €0,27 = €2,49
The VAT 21% will be calculated in the following way per line:
225*0.21 = 47.25
37.59*0.21 = 7.8939 -> rounded to 7.89
895.15*0.21 = 187.9815 -> rounded to 187.98
282*0.21 = 59.22
To obtain the total VAT amount, we will add all these rounded numbers=
47.25+7.89+187.98+59.22 = 302.34
This amount is different from when you would calculate it directly on the total amount of the invoice or quotation: 1439,74*0.21=302.35
Both ways of calculating the VAT are correct.
