Amazon FBA vs FBM fees selling on Amazon is a lucrative business model, but one of the critical decisions sellers face is whether to use Fulfillment by Amazon (FBA) or Fulfillment by Merchant (FBM). While both methods have their advantages, understanding their fee structures is essential for making an informed decision. This blog explores the differences between Amazon FBA vs FBM fees to help you choose the best option for your business.
What is Amazon FBA?
Amazon’s Fulfillment by Amazon (FBA) program permits sellers to store their products in Amazon’s fulfillment centers. Amazon handles storage, packing, shipping, customer service, & returns. This is a convenient option for sellers who want a hands-off approach to order fulfillment.
Amazon FBA Fees
FBA sellers pay various fees, which can impact their profitability. These fees include:
- Fulfillment Fees: Amazon charges per unit for picking, packing, and shipping orders. Fees vary based on items size & weight. For example:
- Small standard-size item (<1 lb): $3.22 per unit
- Large standard-size item (<3 lb): $5.40 per unit
- Oversized item (10-20 lb): $9.39 per unit
- Storage Fees: Amazon charges for storing inventory in fulfillment centers. These fees vary based on the time of the year:
- January – September: $0.87 per cubic foot
- October – December: $2.40 per cubic foot (peak season)
- Long-Term Storage Fees: If inventory sits for over 365 days, Amazon charges $6.90 per cubic foot or $0.15 per unit, whichever is greater.
- Removal & Disposal Fees: If you need to remove unsold inventory, Amazon charges between $0.50 and $2.20 per unit for removals and $0.15 to $0.90 per unit for disposals.
- Returns Processing Fees: For items in categories where Amazon offers free returns (e.g., apparel), sellers pay a fee equivalent to the fulfillment cost per unit.
Pros of FBA
✔ Amazon handles fulfillment, reducing operational stress. ✔ Prime eligibility increases visibility and sales. ✔ Competitive shipping rates through Amazon’s logistics network. ✔ Customer service and returns handled by Amazon.
Cons of FBA
❌ Higher costs, especially for long-term storage. ❌ Less control over inventory and fulfillment. ❌ Risk of unexpected storage fee hikes.
What is Amazon FBM?
With Fulfillment by Merchant (FBM), sellers manage their own storage, packing, and shipping. This option allows sellers to maintain control over their logistics but requires more hands-on effort.
Amazon FBM Fees
FBM sellers avoid Amazon’s fulfillment and storage fees but still incur the following costs:
- Referral Fees: Amazon charges 8% to 15% of the product’s sale price, depending on the category.
- Example: A $50 item with a 15% referral fee incurs a $7.50 fee.
- Shipping Costs: Since sellers ship items themselves, they must account for shipping costs. This varies based on carrier, location, and item weight.
- Amazon Professional Seller Subscription: If using a Professional Seller account, sellers pay $39.99 per month.
- Customer Service & Returns Handling: Sellers must manage customer service and return logistics, which can lead to additional costs.
Pros of FBM
✔ Lower overall fees compared to FBA. ✔ More control over inventory and fulfillment. ✔ Better suited for large, heavy, or slow-moving products. ✔ No long-term storage fees.
Cons of FBM
❌ No Prime eligibility unless using Seller Fulfilled Prime (SFP). ❌ Sellers must handle shipping, returns, and customer service. ❌ Shipping costs may be higher compared to Amazon’s negotiated rates.
