How to use this GST calculator
Choose Exclusive GST when you know the taxable value and want to add GST. Choose Inclusive GST when you only know the final invoice amount and want to extract the taxable value and GST.
For intra-state supplies, GST is split equally into CGST and SGST. For inter-state supplies, the full GST amount is shown as IGST. The place of supply rules decide which one applies.
If you are registered, enter eligible input tax credit to estimate cash payable. This is a planning number only; actual ITC use depends on GST return data, blocked credits, and compliance conditions.
GST calculator FAQs
How do I remove GST from an inclusive invoice?
Choose Inclusive GST, enter the invoice amount, and select the GST rate. The calculator divides the total by 1 plus the GST and cess rate to estimate taxable value.
When should I use CGST and SGST?
Use CGST and SGST for intra-state supplies where supplier and place of supply are in the same state. Each component is half of the GST amount.
When is IGST used?
IGST generally applies on inter-state supplies, imports, and exports where the place of supply is in a different state or territory.
Can I use ITC against GST payable?
Registered businesses can use eligible input tax credit subject to GST law conditions. This calculator only offsets the GST component for a quick cash-payable estimate.
