The listed selling price on Amazon is far from what a seller actually keeps — referral fees, closing fees, shipping, GST and ad spend all take a cut. This calculator brings all of those together into one net profit figure.
How to Use This Calculator
- Enter your selling price and product cost.
- Enter Amazon's referral fee percentage and any closing/fixed fee for your category.
- Enter shipping cost, applicable GST rate, advertising cost per unit, and any other expenses.
- View your net profit, profit margin, ROI and break-even selling price.
How the Calculation Works
Total Fees = (Selling Price × Referral Fee %) + Closing Fee + Shipping + Advertising + Other ExpensesNet Profit = Selling Price − Product Cost − Total Fees − GST PayableProfit Margin % = (Net Profit ÷ Selling Price) × 100ROI % = (Net Profit ÷ Product Cost) × 100
Worked Example
A product sold at ₹999 with a product cost of ₹350, an 8% referral fee (≈₹80), ₹50 closing fee, ₹60 shipping, ₹40 GST-adjusted amount and ₹70 ad spend per unit leaves an estimated net profit of roughly ₹349, a margin of about 35% and healthy ROI — see the calculator above to model your own fee structure.
Who Should Use This
Amazon sellers pricing new listings, or reviewing existing SKUs to identify which products are genuinely profitable once all fees are accounted for.
Important Considerations
Amazon's referral fee percentage varies by product category, and closing fees, storage fees (FBA) and advertising costs change frequently — always use your current, category-specific fee schedule from Seller Central rather than a generic assumption.
Common Mistakes
Calculating margin on selling price alone without subtracting Amazon's fees, GST liability and ad spend consistently overstates profitability — many sellers only discover the true margin after several loss-making months.
