If you sell on Amazon using Fulfillment by Amazon (FBA), you already know the sting: fees eat into your profit on every single order. Between referral fees, fulfillment fees, storage fees, and various surcharges, a typical Amazon seller hands over 30% to 40% of their revenue to Amazon before seeing a dime of profit.
For many sellers, FBA fees are the single largest expense in their business. And with Amazon adjusting its fee structure nearly every year, costs have only trended upward. In 2026, the pressure on margins is real — especially for sellers in competitive niches where pricing power is limited.
The good news? You don't have to accept these fees as fixed costs. With the right strategies, you can meaningfully reduce what you pay Amazon and reclaim thousands of dollars per year. In this guide, we break down 11 actionable ways to reduce your Amazon FBA fees — with specific steps you can take today and realistic estimates of how much each tactic can save you.
How to Reduce Amazon FBA Fees: 11 Proven Strategies
1. Optimize Product Packaging Size
Amazon's FBA fulfillment fees are heavily tied to product size tier. Even a small reduction in your packaging dimensions can drop your product into a lower size tier — and that means a lower fee on every unit sold.
For example, moving from the "Large Standard-Size" tier to the "Small Standard-Size" tier can save you anywhere from $1 to $3 per unit. Multiply that by thousands of units per month, and the savings are substantial.
What to do:
- Measure your current packaged product dimensions precisely (length, width, height, and weight).
- Check Amazon's current size tier thresholds and see how close you are to the next lower tier.
- Work with your supplier or packaging designer to reduce dimensions — even half an inch can matter.
- Consider vacuum-sealing soft goods, removing excess air from bags, or switching to a more compact box design.
Estimated savings: $1–$3 per unit
2. Reduce Product Weight
Weight is the other major factor in FBA fulfillment fees. Amazon uses dimensional weight or actual weight (whichever is greater) to calculate your fee. Lighter products cost less to fulfill — period.
What to do:
- Switch to lighter packaging materials. For example, replace corrugated boxes with poly mailers where appropriate.
- Use thinner cardboard inserts or eliminate unnecessary packaging layers.
- Ask your manufacturer if lighter-weight materials can be used for the product itself without sacrificing quality.
- Remove heavy printed manuals and replace them with QR codes linking to online instructions.
Estimated savings: $0.50–$2.00 per unit
3. Avoid Long-Term Storage Fees
Amazon charges monthly inventory storage fees, but the real killer is the aged inventory surcharge (formerly called long-term storage fees). Inventory sitting in Amazon's warehouses for more than 181 days gets hit with escalating surcharges, and items stored over 365 days face the steepest penalties.
The key metric here is inventory turnover. Aim to keep your inventory turning over within 90 days whenever possible.
What to do:
- Use Amazon's Inventory Health dashboard to monitor your sell-through rate and days of supply.
- Send smaller, more frequent shipments rather than one massive shipment per quarter.
- Set up automated removal orders for inventory approaching the 181-day mark.
- Run promotions or adjust pricing to accelerate sales of slow-moving SKUs before surcharges kick in.
Estimated savings: $0.50–$6.90+ per cubic foot per month on aged inventory
4. Use Amazon's Partnered Carrier Program
When shipping inventory to Amazon's fulfillment centers, you can use Amazon's Partnered Carrier program to get significantly discounted shipping rates. Amazon has negotiated bulk rates with carriers like UPS that are typically much cheaper than what you'd get on your own.
What to do:
- When creating a shipping plan in Seller Central, select "Amazon Partnered Carrier" instead of using your own carrier.
- Compare the partnered rate with your current shipping cost — in most cases, Amazon's rate is 30%–50% lower.
- For full truckload (FTL) and less-than-truckload (LTL) shipments, Amazon's partnered rates can save even more.
Estimated savings: 30%–50% on inbound shipping costs
5. Enroll in the FBA Small and Light Program
If you sell products that are priced under $12 and weigh 3 ounces or less, the FBA Small and Light program (now integrated into Amazon's Low-Price FBA rates) can dramatically reduce your fulfillment fees. These items qualify for reduced per-unit fees that are often 20%–40% lower than standard FBA rates.
What to do:
- Review your catalog for products that meet the price and weight thresholds.
- Check the latest eligibility criteria — Amazon updates these periodically.
- Enroll qualifying ASINs through Seller Central.
- Consider whether adjusting your price point to fall below the threshold makes sense from a total profitability standpoint.
Estimated savings: $0.30–$1.50 per unit on qualifying items
6. Remove or Liquidate Slow-Moving Inventory
Dead stock is not just an opportunity cost — it's an active drain on your profits through ongoing storage fees and aged inventory surcharges. Sometimes the smartest financial move is to cut your losses and get that inventory out of Amazon's warehouse.
What to do:
- Use Amazon's FBA Liquidations program to recover partial value from excess inventory.
- Create removal orders to have inventory shipped back to you, then sell it through other channels (eBay, your own website, local liquidation).
- Run deep discount promotions, Lightning Deals, or coupons to clear slow movers before storage surcharges apply.
- Set up automated removal rules in Seller Central for items that hit a certain age threshold.
Estimated savings: $2–$10+ per cubic foot per month in avoided surcharges
7. Optimize Your Pricing to Avoid Referral Fee Breakpoints
Amazon's referral fee is a percentage of your selling price, typically 15% in most categories. But here's what many sellers overlook: there's usually a minimum referral fee (often $0.30). If your product is priced very low, you could end up paying a higher effective referral fee percentage than necessary.
What to do:
- Calculate the effective referral fee percentage at your current price point.
- Check whether a small price increase would keep you in the same competitive range while reducing your effective fee percentage.
- For products sold in multipacks, bundle pricing can sometimes result in more favorable referral fee economics than selling individual units.
- Review category-specific referral fee rates — some categories have lower percentages than others. If your product fits multiple categories, choose wisely.
Estimated savings: 1%–3% of revenue on affected SKUs
8. Use Multi-Channel Fulfillment Strategically
Amazon's Multi-Channel Fulfillment (MCF) lets you use your FBA inventory to fulfill orders from other sales channels — your Shopify store, eBay, Walmart, and more. While MCF fees are higher than standard FBA fees, it can save money compared to maintaining separate inventory pools and fulfillment operations.
What to do:
- Evaluate whether consolidating inventory in FBA for multi-channel fulfillment reduces your total logistics cost.
- Use MCF for channels where you have moderate but not high volume — it eliminates the need for a separate 3PL.
- Monitor MCF fees carefully and compare them against alternatives like ShipBob, Deliverr, or self-fulfillment.
- Take advantage of MCF's unbranded packaging option to keep a professional appearance on non-Amazon orders.
Estimated savings: Varies — potential to save $1,000–$5,000+/year in warehousing and fulfillment overhead
9. Consider FBA vs. FBM for Low-Margin Products
Not every product in your catalog belongs in FBA. For low-margin, heavy, or slow-selling items, Fulfillment by Merchant (FBM) can be significantly cheaper. You lose the Prime badge, but if your margins are razor-thin, that trade-off might be worth it.
What to do:
- Run a profitability analysis on every SKU. Use an FBA fee calculator to compare your net profit under FBA vs. FBM.
- Products with high storage-to-sales ratios (bulky items that sell slowly) are prime candidates for FBM.
- Consider Seller Fulfilled Prime (SFP) if you can meet the delivery speed and reliability requirements — you keep the Prime badge while controlling fulfillment costs.
- For seasonal products, switch between FBA and FBM based on demand cycles.
Estimated savings: $2–$5+ per unit on qualifying products
10. Monitor and Dispute FBA Errors
Amazon's warehouses are massive, complex operations — and mistakes happen. Inventory gets lost, damaged, miscounted, or improperly charged. Amazon has reimbursement policies for these errors, but they don't always apply credits automatically. You often have to ask.
What to do:
- Regularly audit your FBA inventory reports: look for discrepancies in received quantities, damaged inventory, and customer return conditions.
- File reimbursement claims through Seller Central for items that were lost or damaged while in Amazon's possession.
- Check for overcharged weight or dimension fees — Amazon's measurements don't always match reality.
- Use third-party reimbursement services if you don't have time to do this manually (many work on a percentage-of-recovery basis).
Estimated savings: 1%–3% of annual FBA fees recovered
11. Use Fee Calculation Tools Before Every Product Decision
One of the most costly mistakes Amazon sellers make is launching a product or adjusting pricing without fully understanding the fee implications. Amazon's fee structure is complex, and small changes in price, size, or weight can swing your profitability dramatically.
What to do:
- Use a reliable Amazon FBA fee calculator before sourcing any new product. SellerGains's free FBA Calculator lets you quickly estimate all FBA fees — fulfillment, referral, storage — and see your true net margin.
- Re-run fee calculations whenever Amazon announces fee changes (typically announced in Q4 for the following year).
- Model different scenarios: What happens if you reduce the package size by one inch? What if you raise the price by $1? A good calculator helps you find the optimal configuration.
- Make fee analysis a standard part of your product research workflow — not an afterthought.
Estimated savings: Prevents costly mistakes and ensures every product decision is profit-optimized
How Much Can You Actually Save?
Let's put some real numbers behind these strategies. If you're selling 1,000 units per month at an average selling price of $25:
- Packaging optimization (moving down one size tier): $1.50/unit = $1,500/month
- Weight reduction: $0.75/unit = $750/month
- Avoiding long-term storage fees: $200–$500/month
- Partnered carrier savings: $300–$600/month on inbound shipping
- FBA error reimbursements: $100–$300/month
Combined, a seller doing $25,000/month in revenue could realistically save $3,000 to $4,000 per month — that's $36,000 to $48,000 per year going back into your bottom line.
Even if you only implement three or four of these strategies, you're likely looking at saving 5%–10% of your total Amazon fees. On a business doing six or seven figures in revenue, that's serious money.
The key is to start with the strategies that require the least effort for the biggest impact. For most sellers, that means: (1) checking your size tier and optimizing packaging, (2) cleaning up slow-moving inventory, and (3) using a proper FBA fee calculator for all product decisions going forward.
Frequently Asked Questions
What is the biggest FBA fee most sellers pay?
For most sellers, the referral fee (typically 15% of the sale price) is the single largest FBA-related cost, followed by the fulfillment fee (which covers picking, packing, and shipping). Together, these two fees usually account for 20%–30% of your selling price. While you can't eliminate referral fees, you can reduce fulfillment fees by optimizing your product's size and weight. Use an FBA fee calculator to see exactly how fees break down for your specific product.
Is FBA still worth it in 2026 with rising fees?
For most sellers, yes — FBA is still worth it. The Prime badge, customer trust, and hands-off fulfillment provide significant value that's hard to replicate with self-fulfillment. However, it's no longer a "set it and forget it" decision. You need to actively manage your fees, optimize your packaging, and regularly evaluate whether each SKU is more profitable under FBA or FBM. Sellers who treat fee optimization as an ongoing process continue to thrive with FBA.
How often does Amazon change its FBA fee structure?
Amazon typically announces FBA fee changes once per year, usually in late Q4 (November or December) with changes taking effect in January or February of the following year. However, Amazon can and does make mid-year adjustments, introduce new surcharges (like fuel and inflation surcharges), or change program eligibility criteria at any time. It's a good practice to review Amazon's fee announcements quarterly and re-run your profitability calculations whenever changes are announced.
