How is GST calculated on an amount?
To add GST, GST = amount × rate ÷ 100 and total = amount + GST. To remove GST from an inclusive price, base = amount × 100 ÷ (100 + rate).
What is the CGST and SGST split?
For intra-state sales the GST is shared equally: CGST = SGST = half the total GST. For inter-state sales the full amount is charged as IGST.
What are the GST slabs in India?
