How to Calculate Your Amazon FBA Profit
Understanding your true profitability is the difference between a successful Amazon business and one that drains your bank account. The Amazon FBA Profit Calculator helps you visualize every expense associated with the "Fulfillment by Amazon" business model.
Key Factors in FBA Profitability
- Selling Price: The final amount the customer pays for your product.
- Cost of Goods Sold (COGS): The manufacturing cost per unit paid to your supplier.
- Amazon Referral Fee: Typically 15% for most categories, this is Amazon's commission for the sale.
- FBA Fulfillment Fee: The cost for Amazon to pick, pack, ship, and provide customer service for your orders. This varies based on weight and dimensions.
- Shipping to Amazon: The freight cost (Air, Sea, or Small Parcel) to get your inventory from the factory to an Amazon Fulfillment Center.
A Realistic Example
Imagine you are selling a yoga mat for $40.00. Your manufacturing cost is $10.00, and shipping it to Amazon costs $2.00 per unit. Amazon takes a 15% referral fee ($6.00) and charges an FBA fee of $7.50. After accounting for $2.00 in PPC advertising costs, your net profit would be $12.50 per unit. This results in a 31.25% margin and a 104% ROI on your inventory spend.
Why Monitoring ROI and Margin Matters
While many sellers focus on "Gross Revenue," savvy sellers look at Net Profit Margin. A healthy FBA margin is typically between 20% and 30%. Your ROI (Return on Investment) tells you how hard your money is working for you; an ROI over 100% means you are doubling your money with every inventory turn.
