Selling on Amazon can be incredibly profitable, but only when you understand your true costs and profit margins. Many new and experienced sellers overlook critical expenses such as Amazon referral fees, shipping costs, and product sourcing costs. This often leads to underpriced listings or slim margins.
Amazon FBM Calculator
What is the Amazon FBM Calculator?
The Amazon FBM Calculator is a free online tool designed for sellers who fulfill their own orders (FBM). Unlike FBA (Fulfilled by Amazon), where Amazon handles shipping and customer service, FBM sellers are responsible for storage, packing, and delivery.
This calculator simplifies profit analysis by factoring in:
- Selling Price – the price you list your product for on Amazon.
- Product Cost – the amount you paid to source the product.
- Shipping Cost – the expense you incur to deliver the item to the customer.
- Amazon Referral Fee (%) – the percentage Amazon takes from every sale.
With these inputs, the calculator shows:
- Amazon Referral Fee (in $)
- Total Cost (product cost + shipping + fees)
- Net Profit (earning after costs)
- Profit Margin (%)
Why Use an Amazon FBM Calculator?
Here are the key benefits of using this tool:
- Instant Profit Insights – Quickly see if your product is profitable.
- Smart Pricing Decisions – Adjust your selling price to stay competitive while maintaining margins.
- Avoid Losses – Prevent underpricing by knowing your break-even point.
- Plan Ahead – Test different cost and fee scenarios before launching new products.
- Stay Compliant – Ensure you factor in Amazon’s referral fees accurately.
How to Use the Amazon FBM Calculator
Using the calculator is simple and requires just four steps:
- Enter Your Selling Price – Input the price you plan to sell the product for on Amazon.
- Enter Shipping Cost – Add the cost you’ll pay to ship the item to your buyer.
- Enter Product Cost – Input how much it costs to source the item from your supplier.

Finally, click Calculate and you’ll instantly see:

Example: FBM Profit Calculation
Let’s take an example to see how this works:
- Selling Price: $50
- Shipping Cost: $6
- Product Cost: $20
- Amazon Referral Fee (%): 15%
Step 1: Amazon Fee = $50 × 15% = $7.50
Step 2: Total Cost = $20 (product) + $6 (shipping) + $7.50 (fee) = $33.50
Step 3: Net Profit = $50 – $33.50 = $16.50
Step 4: Profit Margin = ($16.50 ÷ $50) × 100 = 33%
So, if you list this product for $50, you’ll make $16.50 profit per unit with a 33% margin.
Tips for Maximizing FBM Profits
- Negotiate with Suppliers: Lower product sourcing costs to improve margins.
- Optimize Shipping: Use discounted courier services or negotiate bulk shipping rates.
- Price Strategically: Don’t always undercut competitors; sometimes higher pricing sells better with good product value.
- Understand Category Fees: Referral fees vary by category—double-check your product category on Amazon.
- Bundle Products: Increase average order value with product bundles.
