How to Use the Amazon FBA Profit Calculator
Selling on Amazon via Fulfillment by Amazon (FBA) is a lucrative business model, but the fees can be complex. This calculator helps you strip away the guesswork by accounting for all major expenses involved in a single sale.
Understanding the Inputs
- Cost of Goods (COGS): The total amount you paid the manufacturer to produce one unit.
- Shipping to Amazon: The cost to transport one unit from your warehouse or supplier to Amazon's fulfillment centers.
- Referral Fee: Amazon's "commission" for selling on their platform. For most categories, this is 15% of the total sale price.
- FBA Fulfillment Fee: This covers picking, packing, and shipping to the customer. It is based on the weight and dimensions of your product.
- Monthly Storage Fee: Amazon charges for the space your inventory occupies. This varies by season (higher in Q4).
- Marketing/PPC: Don't forget to include your average advertising spend divided by the number of units sold.
Example Calculation
Let's say you are selling a "Premium Kitchen Spatula":
- Sale Price: $25.00
- Cost of Goods: $5.00
- Shipping to Amazon: $1.00
- Referral Fee (15%): $3.75
- FBA Fee: $4.50
- PPC/Marketing: $2.00
Total Expenses: $5.00 + $1.00 + $3.75 + $4.50 + $2.00 = $16.25
Net Profit: $25.00 – $16.25 = $8.75
Profit Margin: 35%
Strategies to Improve Your FBA Margins
If your results aren't where you want them to be, consider these three strategies:
- Optimize Packaging: A small reduction in box dimensions can drop you into a lower FBA fee tier, saving you dollars per unit.
- Bulk Shipping: Use sea freight instead of air freight to significantly lower your "Shipping to Amazon" costs.
- Improve Conversion Rates: Higher organic sales reduce your average PPC spend per unit, directly increasing your net profit margin.
