How It Works
Profitability on Amazon hinges on three fee buckets that are easy to overlook: fulfillment, referral, and storage. Modeled against the 2026 rate schedule, this tool turns those charges into a clear profit-per-unit figure and a monthly earnings projection, which is exactly the information you need to price a product so it actually clears a margin.
Each fee type is applied to your own product data. Fulfillment is a per-unit charge driven by size and weight, referral is a percentage tied to your product category, and storage is billed monthly. To put numbers to it, standard-size fulfillment for a 1lb item might run $3.77 in 2026, while referral fees on electronics typically sit at 8% for items up to $100. The calculator runs your inputs through these rates to land on total cost and net profit.
Storage is where margins quietly erode, particularly on oversized or slow-moving stock, and inventory sitting for more than 270 days picks up long-term storage charges on top of that. Inbound shipping to Amazon's fulfillment centers is another real cost that falls outside this tool entirely, so build that figure in separately before you treat any profit number as final.
Example: Selling a 'Wireless Bluetooth Speaker'
- 1 Input: Item Price: $49.99, Product Cost: $15.00, Shipping Cost to FBA: $2.00, Dimensions: 6x4x3 inches, Weight: 1.2 lbs, Category: Electronics, Monthly Sales Volume: 150 units.
- 2 Calculate: FBA Fulfillment Fee (standard, 1.2 lbs): ~$4.05. Referral Fee (8% of $49.99): ~$4.00. Monthly Storage Fee (standard-size, per cubic foot): ~$0.93/month (assuming 0.042 cubic feet per unit).
- 3 Result: Per Unit Profit: ~$24.94. Monthly Net Profit: ~$3,741.00.
- 4 Context: This profit projection allows you to assess the viability of your product and adjust pricing or sourcing strategies as needed. Remember to consider advertising costs and returns when finalizing your overall business plan.
