CALCULATOR & PLANNER

Product contribution and margin calculator

Separate sales revenue, variable cost, contribution and gross margin before deciding what an order can support.

Example inputs are illustrative, not recommended prices. Your entries stay in this page's memory; this tool does not send, save or apply them to your store.

How the calculation works

Price minus product cost gives gross profit. Subtract packing and the entered payment fee to estimate contribution. This is not net profit: fixed costs, taxes, refunds and owner costs not entered remain excluded.

Worked example

At ₹1,000 with ₹600 product cost, ₹50 packing and a 2% fee, gross margin is 40% and contribution is ₹330.

Use the result carefully

Do not compare this result with another product whose cost boundary excludes different items.

Choose a consistent time period and cost boundary. Keep a note of where each input came from, then compare the scenario with actual results. Money is displayed in rupees to two decimal places; calculation precision and rounding are described above.

Before using this in your business

  1. Replace every example input with a value you can explain.
  2. Check that taxes, refunds, shipping, labour and fixed costs are included or excluded deliberately.
  3. Run a conservative scenario as well as your expected case.
  4. Do not treat the output as a price quotation, tax advice, credit decision or automatic store setting.
