How to Calculate Amazon Seller Profitability
Selling on Amazon can be highly lucrative, but understanding your true net profit is essential for long-term success. Many new sellers focus solely on the sale price, forgetting that Amazon takes a significant cut through various fees. Our Amazon FBA Profit Calculator helps you visualize the "take-home" pay after all expenses are accounted for.
Understanding the Key Metrics
Cost of Goods (COGS): This is the total cost to manufacture or purchase your product. It should include factory costs, packaging, and any quality inspection fees.
Referral Fees: Amazon typically charges a percentage of the total sale price (usually 8% to 15% depending on the category). This is essentially their "commission" for providing the marketplace.
FBA Fees: If you use "Fulfillment by Amazon," these fees cover storage, picking, packing, and shipping to the customer. These are determined by the weight and dimensions of your product.
Example Calculation: Private Label Product
- Sale Price: $40.00
- Product Cost: $10.00
- FBA Fees: $6.50
- Referral Fee (15%): $6.00
- Marketing (PPC): $4.00
- Total Expenses: $26.50
- Net Profit: $13.50
- Profit Margin: 33.75%
3 Tips to Increase Your Amazon Profit Margins
- Optimize Packaging: Reducing the size or weight of your product by even an inch or an ounce can move you into a lower FBA fee tier, saving you dollars on every single sale.
- Bundle Products: By bundling two items together, you pay the FBA shipping fee once instead of twice, significantly increasing the margin per order.
- Negotiate with Suppliers: Once you have a steady sales volume, renegotiate your unit cost. A $0.50 reduction in COGS goes directly to your bottom line.
