GST calculation formula

Exclusive GST formula

GST Amount = (Taxable Value × GST Rate) / 100 Final Price = Taxable Value + GST Amount

Inclusive GST formula

Taxable Value = Total Price × 100 / (100 + GST Rate) GST Amount = Total Price - Taxable Value

Example

If the taxable value is ₹10,000 and the GST rate is 18%, then the GST amount is ₹1,800 and the final price becomes ₹11,800 in exclusive mode. In inclusive mode, if the final price is ₹11,800, the calculator can extract the taxable amount and GST automatically.

Difference between CGST, SGST, and IGST

CGST is collected by the central government for intra-state sales.
SGST is collected by the state government for intra-state sales.
IGST is applied to inter-state sales.
