Profit margin is applied as a percentage of the cost price to get the taxable value; GST and cess are then charged on that taxable value. Cess applies only to certain goods — leave it at 0 if your product has none. Always confirm the correct GST and cess for your HSN/SAC from the official schedule or your accountant.

How selling price is calculated

  1. Enter your cost price (the price you paid, without GST).
  2. Add an optional profit margin % — this is added to the cost to form the taxable value.
  3. Pick the GST rate and add cess % if your goods attract it.
  4. Read the result: cost, profit, GST, cess and your final selling price, with a visual split.

The formula

  • Taxable value = Cost price + (Cost price × profit % ÷ 100)
  • GST = Taxable value × GST % ÷ 100
  • Cess = Taxable value × cess % ÷ 100
  • Selling price = Taxable value + GST + Cess

For example, a cost price of ₹1,00,000 at 18% GST with no profit margin gives a selling price of ₹1,18,000. Add a 20% profit margin and the taxable value becomes ₹1,20,000, with GST of ₹21,600 and a selling price of ₹1,41,600.

Why use a margin calculator?

It helps you set a price that protects your profit after tax, prepare quotes, and see clearly how much of the final price is your cost, your profit and the tax you collect on behalf of the government. To simply add or remove GST from a figure, use the GST Calculator or the Reverse GST Calculator.

Worked example: from purchase price to shelf price

You buy an item for ₹800, want 25% profit, and it attracts 18% GST with no cess. Profit = 800 × 25% = ₹200, so the taxable value is ₹1,000. GST = ₹180. Your GST-inclusive selling price is ₹1,180. Note what this shows: the ₹180 tax is collected from the buyer and paid onward — your earning is the ₹200 profit, not ₹380. Pricing "₹1,000 plus whatever" without doing this chain is how shops accidentally sell at 7–8% real margin while believing it's 25%.

Markup vs margin — don't mix them up

Markup is profit ÷ cost; margin is profit ÷ selling price. The same ₹200 profit on ₹800 cost is a 25% markup but only a 16.9% margin on the ₹1,180 inclusive price (20% on the ₹1,000 taxable value). Suppliers, marketplaces and accountants may quote either one — always ask which. This calculator works on markup-on-cost, the convention most Indian traders use when they say "25% margin".

Don't forget the GST you can claim back

If you are GST-registered, the GST you paid on the purchase is input tax credit, so your true cost is the pre-tax purchase price, not the invoice total. Enter that pre-tax cost here for an honest margin. (To pull the base price out of a GST-inclusive purchase bill, use the Reverse GST Calculator first.) Composition dealers and unregistered sellers can't claim ITC, so they should use the full purchase price as cost.

Is profit margin on cost or on selling price?
This tool applies the margin as a percentage of the cost price, the most common mark-up method for traders. If you price on selling-price margin, adjust your percentage accordingly.
What is cess?
Cess is an extra levy on certain goods, charged on top of GST. If your product does not attract cess, leave the field at zero.
Does the GST go to me?
No. GST and cess are collected from the buyer and paid to the government. Only the cost recovery and profit portions are yours.
How do I set an MRP that already includes GST?
Use this tool: cost + profit% gives the taxable value; GST is added on top; the total is your inclusive price. Round it to a clean shelf number and re-check the implied margin.
What's the difference between markup and margin?
Markup = profit ÷ cost; margin = profit ÷ selling price. 25% markup ≈ 20% margin on the taxable value. This calculator uses markup on cost.
Should I use my purchase bill total as the cost?
If you're registered and can claim input credit, use the pre-GST purchase price as cost (extract it with the Reverse GST Calculator). If you can't claim ITC, use the full amount you actually paid.
