How to calculate VAT

•Excluding VAT from gross amount:
VAT calculation formula is the following: to calculate VAT having the gross amount you should divide the gross amount by 1 + VAT percentage (i.e. if it is 15%, then you should divide by 1.15), then subtract the gross amount, multiply by -1 and round to the closest value (including cents). Last two operations are not arbitrary since you see the value even before you do them.
•Adding VAT to net amount:
Easy deal. Simply multiply the net amount by 1 + VAT percentage (i.e. multiply by 1.15 if VAT is 15%) and you'll get the gross amount. Or multiply by VAT percentage to get the VAT amount. Rembember to round to cents.
