How to calculate VAGST in Samoa
Adding VAGST to a net price
VAGST = net × 15 / 100
gross = net × 1.15
Removing VAGST from a gross price
net = gross / 1.15
VAGST = gross − net
A common mistake is to take 15% off the gross price. That gives the wrong figure: the VAGST inside a gross price is only 13.04% of it.
