Amazon FBA Profitability

Fulfillment by Amazon (FBA) is an incredible service giving third-party sellers access to Amazon Prime's massive customer base and 2-day logistical delivery network. However, Amazon charges a complex array of fees that can rapidly obliterate unwary sellers' profit margins if not calculated meticulously before sourcing.

Navigating Amazon Fees

Fulfillment Fees

A flat fee charged by Amazon for picking, packing, shipping, and providing customer service for your product. It scales heavily with the size, weight, and dimensional volume of the item.

Referral Fees

Usually around 15% (varies by category), this is essentially the "commission" Amazon takes for providing the customer and processing the payment on their platform.

Storage / Disposal / Advertising

Our calculator provides the base per-unit transaction ROI. Sellers must also account for monthly inventory storage fees, inbound shipping, and PPC (Pay-Per-Click) advertising costs.

FBA Success Tactics

Target small, lightweight, high-priced items (like jewelry or small electronics) to minimize Amazon’s size-based fulfillment fees.
Do not sell oversized or heavy items via FBA unless your margins are astronomically high. Dimensional weight pricing will destroy profitability.
Factor in at least a 20-30% buffer for PPC launch advertising before you ever see organic page-1 sales.

Frequently Asked Questions

What is a good FBA margin?
Most full-time FBA sellers target a net profit margin of at least 25% to 30% after all fees and landed sourcing costs are deducted.
Do I pay the referral fee on shipping?
Yes, if you fulfill the item yourself (FBM) and charge shipping, Amazon takes its referral fee out of the total customer payment (Price + Shipping).
