Frequently Asked Questions

How do I calculate GST?

To calculate GST, simply multiply the base amount by the GST rate percentage. For example, to calculate 18% GST on ₹1,000, the GST amount is ₹1,000 × 18% = ₹180. The total amount is ₹1,180.

What is reverse GST calculation?

Reverse GST calculation (or removing GST) helps you find the original base price when you only have the final price that already includes GST. It's calculated as: Final Price / (1 + (GST Rate / 100)).

What are CGST, SGST, and IGST?

CGST (Central GST) and SGST (State GST) are levied on intra-state supplies (within the same state), typically splitting the total GST rate equally. IGST (Integrated GST) is levied on inter-state supplies (between two states) and is equal to the total GST rate.

What are the common GST slabs?

In India, the most common standard GST tax slabs are 0%, 5%, 12%, 18%, and 28%. Different products and services fall under different slabs as determined by the GST Council.
