Why FBA Fee Optimization Matters
Amazon FBA Small and Light vs Standard fulfillment is a comparison that can mean the difference between a profitable product and a money-losing one. For products under $12 and weighing less than 3 pounds, the savings from the Small and Light program (now called Low-Price FBA) can be $1.00 to $2.50+ per unit. At scale, that is tens of thousands of dollars annually going straight to your bottom line.
At Marknology, fee optimization is one of the first things we audit for every brand. I have seen too many sellers leave money on the table simply because they did not know this program existed or assumed they did not qualify.
Understanding the Programs
Standard FBA: The default fulfillment option. Amazon picks, packs, and ships your product with Prime two-day delivery. Fees are based on size tier and weight.
Small and Light (Low-Price FBA): A reduced-fee program for products priced under $12 (threshold has changed over the years) that are small and lightweight. The tradeoff: delivery is typically 3-5 business days instead of 1-2 day Prime delivery. In 2024-2025, Amazon merged elements of this into their standard fee structure, but weight and size tier optimization remains critical.
"FBA fees, at the bottom end, you're looking at like $2.99 to pick, pack and ship two days anywhere in the US. When we helped a client switch from self-fulfillment, we saved them $10,000 to $15,000 simply by going to FBA." ā Andrew Morgans, Startup Hustle Podcast
Fee Comparison
| Product Example | Standard FBA Fee | Low-Price FBA Fee | Savings Per Unit |
|---|---|---|---|
| Small item (4oz, $8.99) | $3.22 | $2.16 | $1.06 |
| Small item (12oz, $10.99) | $3.86 | $2.73 | $1.13 |
| Small standard (1lb, $11.99) | $4.75 | $3.15 | $1.60 |
| Small standard (2lb, $11.99) | $5.40 | $3.60 | $1.80 |
Note: Fee amounts are approximate and updated periodically by Amazon. Always check the current fee schedule in Seller Central.
At 1,000 units per month, a $1.50 savings per unit equals $18,000 annually. At 5,000 units per month, that is $90,000 back in your pocket.
How to Qualify
- Price threshold: Product must be priced under the current Low-Price threshold (check Seller Central for current limits)
- Size: Must fit within small standard size tier dimensions
- Weight: Under 3 pounds typically
- Enrollment: Enroll eligible ASINs through the FBA settings in Seller Central
Fee Optimization Strategies Beyond Small and Light
Even if your product does not qualify for the Low-Price program, there are multiple ways to reduce FBA fees:
1. Optimize packaging dimensions. Amazon charges based on size tier. Reducing your package by even half an inch can drop you into a lower tier and save $0.50 to $2.00+ per unit. We have seen brands save five figures annually just by redesigning their packaging.
2. Reduce product weight. Every ounce matters in FBA's weight-based fee tiers. Consider lighter packaging materials, removing unnecessary inserts, or reformulating products where possible.
3. Create multi-packs. Sometimes selling a 3-pack at a higher price point gives you better margins than individual units because the per-unit fulfillment cost drops significantly.
4. Monitor the FBA fee calculator. Amazon updates fees annually (usually in January). Run your entire catalog through the fee calculator at least twice a year to catch any changes that affect profitability.
5. Audit your size tier classification. We have found products at Marknology that were misclassified in a larger size tier than they should have been. One correction saved a client over $30,000 annually.
Making It Work for Your Brand
Fee optimization is not glamorous. It does not make for exciting Instagram posts. But it is one of the highest-ROI activities you can do on Amazon. A dollar saved in fulfillment fees is a dollar straight to your bottom line, no advertising spend required.
At Marknology, we run a full fee audit for every brand in our portfolio. It is one of the first things we do because the savings often pay for our services by themselves.
