Formula

GST formulas with discount

The bill calculator applies discount first, then calculates GST on the taxable value.

Row discount

Gross = Amount x Quantity. Discount = Gross x Discount % / 100.

GST after discount

Taxable Value = Gross - Discount. GST Amount = Taxable Value x GST % / 100.

CGST and SGST

For same-state supply, GST is split equally into CGST and SGST.

IGST

For different-state supply, the full GST amount is shown as IGST.
