How to Calculate Amazon FBA Profitability
Selling on Amazon via the FBA (Fulfillment by Amazon) program offers incredible scale, but the fee structure can be complex. To accurately determine if a product is viable, you must look beyond the selling price and account for every cost associated with the transaction.
Understanding the Key Metrics
- Cost of Goods Sold (COGS): This is the manufacturing or wholesale cost of your product.
- Referral Fees: Amazon's "commission" for selling on their platform, typically 15% for most categories.
- Fulfillment Fees: The cost Amazon charges to pick, pack, and ship your product to the customer. This is based on weight and dimensions.
- ROI (Return on Investment): This shows how much money you make relative to what you spent on inventory. An ROI of 100% means you doubled your money.
FBA Profit Calculation Example
"Imagine you sell a Yoga Mat for $40.00. Your sourcing cost is $10.00 and shipping to Amazon is $2.00. Amazon takes a 15% referral fee ($6.00) and a fulfillment fee of $7.50. After subtracting all costs ($40 – $10 – $2 – $6 – $7.50), your Net Profit is $14.50. This results in a 36.25% Profit Margin and a 145% ROI."
Why Margin Matters
Expert Amazon sellers typically aim for a minimum of 25-30% profit margin. This provides a "buffer" for PPC advertising costs, returns, and price fluctuations in the marketplace. If your margin is too slim, a single bad batch or a spike in storage fees could turn your profitable business into a loss-making one.
