How to Calculate Your Amazon FBA Profit
Understanding your numbers is the difference between a successful Amazon business and a failing one. This Amazon FBA Profit Calculator helps you break down the complex fee structure of the Fulfillment by Amazon program.
Key Metrics Explained
- Sale Price: The final amount the customer pays for your product on the Amazon marketplace.
- COGS (Cost of Goods Sold): The total cost to manufacture or purchase one unit of your product.
- Referral Fee: Amazon's "commission" for selling on their platform. For most categories, this is 15%.
- Fulfillment Fee: The cost Amazon charges to pick, pack, and ship your product to the customer. This depends on weight and dimensions.
- ROI (Return on Investment): Calculated as (Net Profit / Total Cost of Goods). This shows how efficiently your capital is working for you.
Example Calculation
Imagine you sell a Yoga Mat for $40.00. Your manufacturing cost is $10.00 and it costs $2.00 to ship it to an Amazon warehouse. Amazon's referral fee is 15% ($6.00), the FBA fulfillment fee is $7.00, and storage is $0.50.
Your total costs would be: $10 + $2 + $6 + $7 + $0.50 = $25.50. Your net profit per unit would be $14.50, resulting in a 36.25% net margin and a 145% ROI.
Why Using an FBA Calculator is Essential
Amazon fees change annually. Between fuel surcharges, peak season storage hikes, and category-specific referral adjustments, manual calculation is prone to error. By using this tool, you can accurately forecast your cash flow and decide which products are worth sourcing from suppliers.
