GST Formulas
Adding GST: GST Amount = Original Price × GST% ÷ 100
Total = Original Price + GST Amount
Removing GST: Original Price = Total ÷ (1 + GST%/100)
GST Amount = Total − Original Price
CGST = SGST = GST Rate ÷ 2 (for intra-state)
IGST = Full GST Rate (for inter-state)
Total = Original Price + GST Amount
Removing GST: Original Price = Total ÷ (1 + GST%/100)
GST Amount = Total − Original Price
CGST = SGST = GST Rate ÷ 2 (for intra-state)
IGST = Full GST Rate (for inter-state)
