GST is calculated on the taxable amount. For an intra-state transaction, the selected GST rate is split between CGST and SGST.
Understand the Calculation
GST made simple.
Goods and Services Tax is an indirect tax applied to many goods and services in India. The calculation depends on the applicable rate and whether the entered amount already includes GST.
GST Inclusive
Use this when the entered price already includes GST. The calculator separates the taxable value and tax component from the total.
CGST, SGST & IGST
For an eligible intra-state supply, GST is generally split into CGST and SGST. For an eligible inter-state supply, IGST generally applies.
GST calculation formulas
GST Exclusive:
GST = Taxable Amount × GST Rate ÷ 100
Final Amount (Exclusive):
Taxable Amount + GST
GST Inclusive:
Taxable Amount = Inclusive Amount ÷ (1 + GST Rate ÷ 100)
Intra-state:
CGST = GST ÷ 2
SGST = GST ÷ 2
Inter-state:
IGST = Total GST
