Calculate the GST component for any transaction — works both ways: given the base price to find the GST-inclusive total, or given the total to extract the base price and tax.
—
Adding GST: Total = Base × (1 + rate/100)
Removing GST: Base = Total / (1 + rate/100)
Intra-state: CGST + SGST = full rate. Inter-state: IGST = full rate.
