- GST rates differ by goods and services and are revised by the GST Council. Enter the rate that applies to your item.
Pricing before tax
Business quotes and B2B prices are often stated before GST. The GST is added as a separate line on the invoice, so the customer pays the base price plus GST.
Checking an invoice
Use the calculator to verify the GST line on a supplier's invoice, or to price your own goods so that the total after GST comes out at the figure you want.
Formula
GST = Price before GST × GST rate ÷ 100
Price including GST = Price before GST + GST
Price before GST = Price including GST ÷ (1 + GST rate ÷ 100)
Where:
- GST rate
- = The tax rate that applies to the goods or service
- CGST / SGST
- = Central and state halves of GST for supplies within a state
- IGST
- = GST for supplies between states
