How it works

GST formulas used

Adding GST (price excludes GST)

GST = Amount × Rate ÷ 100
Total = Amount + GST

Removing GST (price includes GST)

GST = Amount × Rate ÷ (100 + Rate)
Taxable value = Amount − GST

For a supply within the same state, the GST is split equally into CGST and SGST. For inter-state supplies, the full GST is charged as IGST.

Choose Add GST, enter the amount before tax and pick the rate. GST = amount × rate ÷ 100, and the total is the amount plus GST. For ₹10,000 at 18%, GST is ₹1,800 and the total is ₹11,800.

Choose Remove GST and enter the price that already includes GST. GST = price × rate ÷ (100 + rate). For ₹11,800 at 18%, GST is ₹1,800 and the taxable value is ₹10,000.

For a supply within the same state, GST is split equally into Central GST (CGST) and State GST (SGST). For a supply from one state to another, the whole amount is charged as Integrated GST (IGST).
