Seller profit calculator: what do you really earn per sale?

Enter the cost, price, fees, shipping, packaging, ads and returns. See the profit per unit, the margin and what is left after returns. Nothing you type leaves your device.

A worked example

The example is made up. A unit costs ₹250 and sells for ₹599 with GST included at 5%. The platform charges 12% commission and 2% in other fees on the price without GST, a fixed fee of ₹20 and ₹60 for shipping. Packaging is ₹12 and advertising adds ₹25 per order. GST on fees is claimed back.

Sale value without GST₹570.48
Fees and shipping₹159.87
Cost, packaging and ads₹287.00
Profit per delivered unit₹123.61
Margin on sale value21.7%
Expected profit per order placed, after 8% returns₹104.12

The price looks like a profit of ₹349 over the cost, but after removing the GST, fees, shipping, packaging and ads, the real profit is ₹124. Returns reduce it again.

What to do next

  1. Find the price that gives the margin you want with the target price calculator.
  2. Check how many sales you need with break-even.
  3. Test how returns, ads and discounts change the result.
  4. Read the guide to seller fees to be sure you have not missed one.

Common questions

What does the profit calculator work out?

The money you keep from one sale after the cost of the unit, platform fees, shipping, packaging, advertising and the GST arithmetic, and the expected profit after returns. It shows the margin and the return on what you spent.

Why does the price without GST matter?

In most tax systems the GST in a price belongs to the tax authority, not to you. Your sale value is the price without GST, so margins worked out on the full price look better than they are.

Where do I find my fees?

In your seller account: the fee or rate card for your category, your shipping charges and your settlement report. This site does not list them because they change.

Is my data stored?

No. The sums run in your browser and nothing you type is sent anywhere.
