Amazon Seller Guide
How Amazon Fees Work
Amazon sellers need to account for referral fees, FBA fulfillment fees, FBM shipping costs, storage fees, PPC costs, refunds, returns, prep costs, and other seller expenses before pricing or scaling a product.
The main Amazon fees sellers should understand
Referral fees
Amazon usually charges a percentage-based referral fee on the order amount. The rate can vary by product category, sale price, and marketplace rules.
FBA fulfillment fees
If Amazon fulfills the order, FBA fees can cover picking, packing, shipping, handling, and fulfillment-related service costs.
FBM shipping costs
If the seller fulfills the order, the seller should include shipping label cost, packaging, handling time, carrier issues, and any shipping gap.
Storage fees
FBA inventory can create monthly storage cost, aged inventory pressure, and cash flow risk if products sit too long before selling.
Advertising costs
Amazon PPC spend can help listings get visibility, but ad cost can reduce or erase profit if conversion and margin are weak.
Refund and return costs
Refunds, returns, damaged units, replacements, claims, and restocking problems can reduce seller profit after the original sale.
Why estimating Amazon fees matters
An Amazon product can look profitable from the sale price alone, but the real margin may be much lower after referral fees, fulfillment fees, shipping, storage, PPC, refunds, prep, and product cost are included.
Fee estimates help sellers decide whether a product is worth sourcing, whether the price is high enough, whether FBA or FBM is better, and whether PPC spend can be supported by the margin.
The safest approach is to estimate fees before buying inventory, then compare estimated profit against actual seller reports after orders begin.
Common Amazon fee mistakes
- ×Treating sale revenue as profit before subtracting Amazon fees and costs.
- ×Using one referral fee rate for every Amazon category.
- ×Ignoring FBA storage, inbound shipping, prep, labels, and aged inventory risk.
- ×Comparing FBA and FBM without including seller time and shipping control.
- ×Running PPC without checking whether the product has enough margin.
- ×Restocking products before checking refunds, conversion, sales velocity, and storage cost.

How Amazon fees affect pricing
Lower-priced items: Referral fees, minimum fees, shipping, and fulfillment costs can take a larger share of lower-priced sales.
FBA products: FBA can simplify fulfillment, but sellers should include fulfillment fees, inbound shipping, storage, prep, and return risk.
FBM products: FBM can give more control, but sellers must include shipping labels, packaging, handling, support time, and delivery expectations.
Advertising: PPC can increase sales volume, but it should be tested against net profit, not just impressions, clicks, or revenue.
