❓ Frequently Asked Questions
What is CGST and SGST?
For sales within the same state, GST is split equally into CGST (Central GST) collected by the Central Government, and SGST (State GST) collected by the State Government.
How do I calculate price excluding GST?
To extract base price: Base Price = Total Price / (1 + (GST% / 100)). For example, ₹1,180 / 1.18 = ₹1,000 base amount.
