FinBrooks GST Calculator helps you calculate GST on a transaction and understand the taxable value, GST amount and final invoice value.

What is GST?

GST, or Goods and Services Tax, is an indirect tax applicable to the supply of goods and services under India's GST framework.

How do I calculate GST?

When the amount is GST exclusive, GST can be estimated by multiplying the taxable amount by the applicable GST rate. The GST amount is then added to the taxable value to get the total invoice value.

How do I remove GST from an inclusive price?

When a quoted amount already includes GST, the taxable value can be estimated by dividing the inclusive amount by 1 plus the GST rate expressed as a decimal.

What is the difference between CGST, SGST and IGST?

For an eligible intra-state transaction, GST may be represented as CGST and SGST. For an eligible inter-state transaction, IGST may apply. The applicable treatment depends on the transaction and place of supply.

Is this GST calculator suitable for filing GST returns?

No. This calculator is designed for estimation and educational purposes. It should not be used as a substitute for GST accounting, return filing or professional tax advice.
