Understanding Amazon FBA Profitability
Selling on Amazon via Fulfillment by Amazon (FBA) offers massive scale, but the fee structure can be complex. To run a sustainable business, you must calculate your "bottom line" profit after all expenses, not just the cost of goods.
Key Components of the FBA Calculation
- Referral Fee: This is Amazon's commission for selling on their platform. For most categories, this is 15% of the total sale price.
- Fulfillment Fee: This covers the cost of picking, packing, and shipping your product to the customer. It is based on the weight and dimensions of the item.
- Landed Cost: This is the sum of your manufacturing cost and the cost to ship the product from the factory to Amazon's warehouse.
- Storage Fees: Amazon charges monthly fees based on the volume (cubic feet) your inventory occupies in their fulfillment centers.
Example Profit Calculation
Imagine you are selling a "Premium Yoga Mat" for $35.00.
- Product Cost: $10.00
- Shipping to Amazon: $2.00
- Amazon Referral Fee (15%): $5.25
- Fulfillment Fee: $6.50
- Monthly Storage: $0.50
Total Costs: $10 + $2 + $5.25 + $6.50 + $0.50 = $24.25
Net Profit: $35.00 – $24.25 = $10.75
Profit Margin: 30.7% | ROI: 89.5%
Tips to Improve Your FBA Margins
If your margins are below 20%, consider the following strategies:
- Optimize Packaging: Reducing the size or weight of your product packaging can move it into a lower FBA fee tier.
- Bulk Shipping: Use sea freight instead of air freight to lower your per-unit landed cost.
- Increase Price: Sometimes a small price increase of $1-$2 can significantly boost your net margin without affecting conversion rates.
- Monitor Storage: Remove slow-moving inventory to avoid "aged inventory surcharges."
