Inclusive vs Exclusive Confusion: Be clear whether your input amount includes GST or not. This affects the calculation significantly.

Multiple GST Rates: If a transaction involves multiple items with different GST rates, calculate each separately.

Rounding Errors: GST calculations may involve rounding. The tool provides accurate calculations, but final invoices may have slight rounding differences.

CGST/SGST Split: For intra-state transactions, GST is split into CGST and SGST (each half of total GST). This tool shows total GST.

IGST for Inter-State: For inter-state transactions, IGST applies instead of CGST+SGST. The calculation method remains the same.

Reverse Charge: Some transactions use reverse charge mechanism where the recipient pays GST. This calculator assumes normal charge.
