How to use the GST Profit Calculator (India)
- Enter what one unit costs you and the price you sell it for.
- Choose the GST rate for your product's HSN code. Most goods are now 5% or 18%.
- Say whether your selling price already includes GST (like an MRP) or whether GST is added on top.
- If you are GST registered and the cost price includes GST on your purchase, tick input tax credit. The GST on the purchase is then taken out of your cost.
How it is calculated
Price before GST (inclusive price) = selling price ÷ (1 + GST rate) GST you owe = price before GST × GST rate Cost after ITC = cost ÷ (1 + GST rate) (only if you claim input tax credit) Net profit = price before GST − cost (after ITC) Margin = net profit ÷ price before GST × 100
The calculator assumes your purchase was taxed at the same GST rate as your sale. If your supplier charged a different rate, enter your cost without GST and leave input tax credit unticked.

An item sold at ₹1,180 MRP (18% GST), costing ₹700
Of the ₹1,180, ₹180 is GST. Profit is ₹300, not ₹480.

| Net profit | ₹300.00 |
Net profit ₹300.00 · Margin 30%
A GST-registered seller with input tax credit
The ₹90 GST paid on the ₹590 purchase is claimed back, so the real cost is ₹500.
| Price before GST | ₹1,000.00 |
| GST collected (paid to the government) | ₹180.00 |
| Customer pays | ₹1,180.00 |
| Cost after input tax credit | −₹500.00 |

Should my online prices include GST?
For sales to consumers in India, the price you display (the MRP for packaged goods) must include GST. That is why the default is "Including GST": the GST is inside your price and comes out of what you receive. Marketplaces also charge 18% GST on their own fees; use the marketplace fee calculator to include those.
Frequently asked questions
How do I calculate profit after GST?
Remove GST from the selling price first: divide a GST-inclusive price by (1 + rate). Then subtract your cost. For ₹1,180 at 18%: 1,180 ÷ 1.18 = ₹1,000, minus a ₹700 cost = ₹300 profit.
Is GST included in MRP?
Yes. The maximum retail price printed on packaged goods in India includes all taxes, including GST.
What is input tax credit (ITC)?
If you are GST registered, the GST you paid on purchases for your business can be deducted from the GST you owe on sales. That lowers your real cost of goods.
What are the GST rates in India now?
Since 22 September 2025 the main rates are 5% and 18%, with 40% for luxury and sin goods and 0% for exempt items. Gold and jewellery stay at 3%.
I am not GST registered. Which option should I choose?
Choose "Including GST" only if you charge GST. If you are not registered you cannot charge GST, so set the rate to Nil and leave input tax credit unticked; your whole price is then revenue.
