GST calculator
Enter an amount and a GST rate. Choose Add GST if the amount is before tax (exclusive), or Remove GST if tax is already inside it (inclusive). The calculator shows the taxable value, the tax, and the split: CGST + SGST for a sale within your state, IGST for a sale to another state.
GST-exclusive: the amount is the value before tax, and GST is added on top.
Indicative. In Finocket, this split is applied to every invoice line automatically from the place of supply.
How to use it
- 1Enter the amount. Type the price in rupees.
- 2Pick the GST rate. Tap a slab such as 5%, 18% or 28%, or type any rate.
- 3Choose inclusive or exclusive. Add GST to a pre-tax price, or remove GST from a price that already includes it.

Questions
Multiply the pre-tax amount by the rate. At 18%, ₹10,000 carries ₹1,800 of GST, so the total is ₹11,800.
Divide the inclusive amount by (1 + rate). At 18%, ₹11,800 ÷ 1.18 = ₹10,000 taxable value, and the remaining ₹1,800 is the GST.
When the supplier and the place of supply are in the same state, the GST is split equally into CGST and SGST (18% becomes 9% + 9%). When they are in different states, the whole amount is IGST.
