GST formulas
| To find | Formula |
|---|---|
| GST on a price | Price × rate ÷ 100 |
| Price including GST | Price × (100 + rate) ÷ 100 |
| GST inside an inclusive amount | Amount × rate ÷ (100 + rate) |
| Price before GST | Amount × 100 ÷ (100 + rate) |
CGST, SGST and IGST
For a sale within one state, GST is split equally into central GST (CGST) and state GST (SGST, or UTGST in a union territory): 18% becomes 9% + 9%. For a sale between states, the whole amount is integrated GST (IGST).
Veelgestelde vragen

Are the amounts rounded?
Yes, to two decimal places (paise), as on invoices.
Is anything sent anywhere?
No. The calculation happens in your browser, and the amounts you enter never leave your device.
