GST Calculation Formulas
Our calculator uses these standard formulas:
- Add GST: Total Amount = Original Amount + (Original Amount × GST Rate / 100)
- Remove GST: Original Amount = Total Amount / (1 + GST Rate / 100)
- GST Amount: GST Amount = Total Amount - Original Amount
For intra-state transactions, CGST and SGST are each half of the total GST rate. For inter-state transactions, the full rate applies as IGST.
