📊 Understanding the GST Invoice Summary

  • Subtotal – Total of all items before discount

  • Discount – Applied to subtotal

  • Taxable Value – Amount on which GST is calculated

  • CGST & SGST – Split GST for intra-state invoices

  • IGST – Full GST for inter-state invoices

  • Grand Total – Final amount payable by the customer


🧮 GST Calculation Logic Used

Item Total = Quantity × Unit Price
Subtotal = Sum of all item totals
Discount = Subtotal × Discount %
Taxable Value = SubtotalDiscount

For Intra-state:
CGST = Taxable Value × (GST % ÷ 2)
SGST = Taxable Value × (GST % ÷ 2)

For Inter-state:
IGST = Taxable Value × GST %

Grand Total = Taxable Value + GST
