How to Use the Profit Margin Calculator

The Profit Margin Calculator shows your real net profit per unit after every deduction — platform referral fee, fixed closing fee, GST on fees, fulfilment, returns, and advertising. Most sellers underestimate how much Amazon India and Flipkart take from each sale. This calculator makes every line item visible.

A net margin below 15% is risky. A margin below 8% leaves you unable to absorb normal market fluctuations. Calculate your margin before you list, not after your first month's account statement arrives.
