Short answer: with Fulfillment by Amazon you pay a referral fee (15% of the sale price in most categories, minimum $0.30), an FBA fulfillment fee per unit based on size and weight, monthly storage, and your selling plan ($39.99 a month for Professional, or $0.99 per item sold on Individual). The Amazon FBA calculator adds them up per unit.

The four costs of selling with FBA

1. Referral fee

Amazon’s commission on every sale. In most categories it is 15% of the total sale price, with a minimum of $0.30 per item. Some categories have lower or tiered rates, so check yours in Seller Central.

2. FBA fulfillment fee

What Amazon charges to pick, pack, and ship each unit. It depends on the item’s size tier and shipping weight, and Amazon updates the table regularly. Look up the exact fee for your product in Seller Central’s Revenue Calculator, then enter it in our calculator.

3. Storage

Amazon charges monthly storage for the space your inventory takes up in its warehouses, with higher rates in the October to December peak season. Slow-selling stock costs more over time, so storage is worth spreading across the units you expect to sell.

4. Selling plan

The Professional plan costs $39.99 a month. The Individual plan has no monthly fee but charges $0.99 per item sold. Professional makes sense once you sell more than about 40 items a month.

Worked example: a $25 product

Cost per unit	Amount
Sale price	$25.00
Referral fee (15%)	−$3.75
FBA fulfillment fee (example; look yours up)	−$5.00
Product cost, landed	−$8.00
Advertising (PPC) per unit	−$2.00
Professional plan, spread over 200 units a month	−$0.20
Profit per unit	$6.05

That is a 24% profit margin. The example fulfillment fee is only for illustration; your real fee depends on your product’s size and weight.

FBA or FBM?

With Fulfilled by Merchant (FBM) you skip the FBA fulfillment and storage fees but pay your own shipping, packaging, and time. FBA often wins for small, light, fast-selling items. FBM can win for heavy, bulky, or slow-moving products. Run both with the FBA calculator and the FBM calculator using the same product.
