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