Comment calculer
GST Amount = Price × (GST% ÷ 100); Total = Price + GST
Add GST: GST Amount = Net Price × (GST % ÷ 100); Gross Price = Net Price + GST Amount. Remove GST: Net Price = Gross Price ÷ (1 + GST % ÷ 100); GST Amount = Gross Price − Net Price.
* Exemple: $100 item, 10% GST → $10 GST, $110 total
