Understanding GST calculations on your invoice
Indian businesses must show accurate tax amounts. Our free invoice generator with GST does the math for you. Here is a quick example:
- Subtotal of items after discount: ₹10,000
- GST rate: 18% → total tax = ₹1,800
- If intra-state (CGST + SGST): CGST = ₹900, SGST = ₹900
- If inter-state (IGST): IGST = ₹1,800
- Add shipping ₹200 → grand total = ₹12,000
- Advance paid ₹2,000 → balance due = ₹10,000
The generated invoice displays all these components clearly, helping your customer understand exactly what they pay. It also simplifies your tax filing (GSTR-1, GSTR-3B).
