GST Profit Calculator
Separate GST from profit and see exactly what you owe the department.
Enter your purchase and sale prices with their GST rates. You will see your input tax credit, your output GST liability, the net amount payable to the government, and the profit that is genuinely yours.
GST is never your profit
The GST you collect on a sale belongs to the government. You are holding it. Businesses that treat collected GST as revenue feel flush all quarter and then find themselves short at filing time. This calculator strips GST out on both sides so the profit figure is money you can actually keep.
How input tax credit works
The GST you paid your supplier is a credit against the GST you collected from your customer. You remit only the difference. If your input credit exceeds your output liability, the balance carries forward to the next period rather than being refunded in most cases.
Inclusive or exclusive?
If a price already contains GST, the taxable value is price × 100 ÷ (100 + rate) — not price minus the rate percentage, which is a common and expensive error. At 18%, a ₹118 inclusive price has a taxable value of ₹100, not ₹96.76. The calculator handles both conventions; just tell it which you entered.
CGST, SGST and IGST
A supply within your state splits equally into central and state GST. A supply to another state is a single integrated GST at the full rate. The total is identical — only the split and the reporting differ.
Before you rely on the credit
Input tax credit is only available once your supplier has filed their return and the invoice appears in your GSTR-2B. An invoice in your hand is not the same as a credit in your ledger.
