How GST is calculated
Adding GST (exclusive)
GST Amount = Base × Rate ÷ 100
Total = Base + GST Amount
Use this when your price does not include GST and you need to charge the customer GST on top.
Removing GST (inclusive)
Base = Total ÷ (1 + Rate ÷ 100)
GST Amount = Total − Base
Use this when you have a GST-inclusive price and need to find out the base amount and tax component.
Intra-state (CGST + SGST)
CGST = SGST = GST Amount ÷ 2
When both buyer and seller are in the same state, GST is split equally between Central GST and State GST.
Inter-state (IGST)
IGST = Full GST Amount
When buyer and seller are in different states, the full tax applies as Integrated GST.
