Why Amazon FBA Fees Matter
Margins on Amazon can disappear faster than you think. One little fee here, another charge there, and then, boom!, you’re out of money! So bad management will make you wonder if Amazon FBA is profitable or if you’re wasting your time.
Therefore, you need strategies to manage fees and reduce FBA fees. In this guide, you’ll find some simple, proven approaches you can implement today to save money and increase your bottom line.
Key Strategies to Get Low-Price FBA Fees
Getting cheaper FBA fees may seem like a dream, but it’s not. By following the strategies below, you can easily reduce FBA fees and get more profit from each Amazon sale.
1. Understand Amazon FBA Fee Types
Amazon breaks its FBA fees into clear categories. When you are aware of these categories, you can identify areas to save money and, based on these, optimize your Amazon listing.
- Fulfillment fees: This fee is charged per unit based on size and weight.
- Referral fees: A portion of every sale you make goes to Amazon, usually a percentage. The referral fee varies based on categories.
- Storage fees: Monthly fees assessed per cubic foot. Higher fee assessments apply from October to December.
- Returns Processing Fees: This fee applies to categories with free returns. Amazon retains a portion of the returns processing fee provided to the customer when the customer returns products.
Amazon FBA fee tips:
Some of the FBA fee categories are based on a dimensional weight. If your box weighs plenty, but has room for plenty of air, you will pay an air tax.
The majority of referral fees exceed 15 percent in niche categories. Long-term storage fees start after products have been in FBA for over 365 days, often after you don’t expect them!
2. Invest in Low-Price Items
Items under $10 can auto-enroll into Low-Price FBA. You’ll save on fulfillment and storage; that’s why we suggest you always check the fee preview before you ship.
- Eligibility: Unit price ≤ $10. Weight ≤ 12 oz. Dimensions ≤ 16×9×4 in.
- Savings per Tier: Compare fees by size, small standard vs. Low-Price FBA.
- Pro Tips: Modify your price by a few cents to trigger enrollment.
3. Use Smarter Packaging to Reduce Fees
Take control of your dimensional fees by practicing smart packaging and avoiding large boxes for tiny items to reduce FBA fees.
Maximize your potential for savings by selecting a mailer or small box with a dimension that closely matches the product shape and minimizes filler pieces.
If you have multi-piece sets, nest them in a single pouch, and if they come in solid retail boxes, select the Sales Order option “Ships in Product Packaging” to save you prep and boxing steps.
4. Reduce shipping fees with Inventory Placement
It’s important to utilize the Inventory Placement Service (IPS) as part of your overall Amazon FBA strategy.
- Consolidated Shipments:
The goal is to ship as few boxes as possible. Fewer boxes usually means a lower bill. The caveat with Amazon is that they may split a large shipment into smaller regrouped shipments that arrive at multiple FCs.
- Inventory Placement Service (IPS):
Flat fee to send all units to one FC. Usually cost-effective, especially with larger shipments.
- Timing & Restock Limits:
Work around restock limits. Ship your inventory early enough to get ahead of seasonal demand.
- Regional Fee Differences:
There are some larger rates in some regions. Ensure you review your fee preview for each FC.
5. Manage Inventory to Avoid Long-term Storage Fees
Long-term storage fees (LTSF) can negatively impact profitability even if you are working with low-price FBA fees.
LTSF starts applying after an item remains in your inventory for a year. Efficient inventory management is key to moving products quickly in order to alleviate these fees.
When managing inventory, always aim for 60-90 days of inventory. If you are selling seasonal items, try to stagger the shipments so that you do not build up too much product. Monitor your slow-moving SKUs with reports such as the Inventory Age report, the IPI, and others. Once you identify slow-moving and excess stock, you can either run Lightning Deals, issue coupons, or issue a removal order for the excess inventory.
6. Manage Everything with Fee Calculators & Spreadsheets
You cannot manage that which you cannot measure. Start by modeling your low‑price FBA fees with Amazon’s Revenue Calculator for a baseline, then cross‑check with tools like AlgoRift for deeper metrics.
Make a simple Google sheet with links to your cost inputs. Do not use too many links to support fees; you will complicate the workflow process for estimating.
Set up columns for product weight, dimensions, packaging cost, and retail selling prices ($9.99, $12.99, $14.99, etc.). Create blocks/formulas to calculate fees based on the alternating scenarios of small box or padded mailer.
Use conditional formatting to colour code and alert you to a margin that has dropped below your target. Lastly, set up automated alerts.
If you’re comfortable, set up a daily script or Zapier integration that reads your sheet and emails you if any SKU’s margin has dropped below your acceptable threshold, predetermined earlier. You’ll catch a few surprises well in advance of the month-end closing of your P&L statement!
7. When FBA Is Not Cheap: FBM & 3PLs
If you’re weighing between Amazon FBA vs dropshipping, FBA is good for smaller, fast‑moving products. However, heavier and slower-moving SKUs can be hurt by the scale of FBA’s fee structures.
In those cases, you switch to Fulfillment by Merchant (FBM) or Seller‑Fulfilled Prime (SFP)! You still handle the storage and shipping, but you get the advantage of the Amazon buy box.
Third-party logistics partners (3PLs) like ShipBob or Deliverr are also worth a look. They usually charge lower storage rates for larger goods and can also ship quickly within regions. Typically, you are charged per pallet or cubic foot, not by each item.
You can also go hybrid by keeping your best sellers FBA for the quick delivery advantage and routing the merchandise from FBM or a 3PL.
They should allow you to optimize cost by SKU. You should be using your fee calculator spreadsheet to compare landed costs across all three channels.
8. Increase Item Volume to Reduce Referral Fees
You can impact your net rate of referral fees by driving off-Amazon Sales. Register for Amazon’s Brand Referral Bonus, which provides a portion of referral fees back from customers who came from your site.
Use tools like AlgoRift to track coupon codes and bring on influencers. Influencers can promote your product as part of blogs, YouTube channels, and/or social media. When there’s a sale, you only pay a small commission instead of larger referral fees.
You should always compare ROI: if your average referral fee rate is 15 percent, then a 5 percent affiliate commission could increase your margin by 10 percent (when orders are off-Amazon).
If you also factor in less ad spend, it is easy to see why so many brands are moving budgets from PPC to affiliates.
