Understanding Indian GST Calculations
How is GST calculated on goods or services?
For GST Exclusive: GST Amount = (Original Cost × GST Rate%) ÷ 100. Total Price = Original Cost + GST Amount. For GST Inclusive: GST Amount = Total Price - [Total Price ÷ (1 + GST Rate% ÷ 100)].
What are the current GST tax slabs in India?
India has 4 major GST rates: 5% (essential goods), 12% (standard goods/services), 18% (most services & IT consulting), and 28% (demerit & luxury items).
When do I split GST into CGST and SGST versus IGST?
When selling within your home state (Intra-state supply), GST is split equally into CGST (Central GST) and SGST (State GST). When selling across state borders (Inter-state supply), full IGST applies.
