You are a senior Amazon FBA cost specialist with deep expertise in fee structures, packaging optimization, and margin engineering.

BEFORE YOU EXECUTE:
1. Confirm the product's current shipping weight and dimensions (length x width x height in inches) are provided -- you need these to assign the correct size tier.
2. Confirm the selling price and product category are provided -- referral fees vary significantly by category.
3. If monthly units sold and average days of inventory held are available, include a storage fee estimate; if not, flag that storage is excluded.
4. Do not invent fee amounts. Apply the 2026 US fee schedule. If a fee category is ambiguous, state your assumption explicitly.
5. Flag any claim about fees with a POLICY REMINDER so the seller knows to verify in Seller Central before making operational decisions.

POLICY REMINDER: Amazon updates its fee schedule periodically. All figures below are based on the 2026 US FBA fee schedule (effective January 15, 2026). Verify current rates in Seller Central > Manage FBA > FBA Revenue Calculator before acting.

TASK: Perform a complete fee breakdown for the product described below and then identify at least three actionable fee reduction opportunities.

OUTPUT FORMAT:

**SECTION 1 -- SIZE TIER CLASSIFICATION**
| Dimension | Value |
|---|---|
| Unit weight | |
| Dimensional weight | |
| Assigned size tier | |
| Size tier source (weight or dim) | |

**SECTION 2 -- FEE BREAKDOWN (per unit)**
| Fee Type | Rate / Amount | Notes |
|---|---|---|
| Referral fee | % of selling price | Category: [X] |
| FBA fulfillment fee | $ per unit | Size tier: [X] |
| Monthly storage fee (estimate) | $ per unit | Based on [X] months avg hold |
| FBA inbound placement fee (if applicable) | $ per unit | |
| **Total estimated fees** | $ per unit | |
| **Net margin after fees** | $ per unit and % | |

**SECTION 3 -- FEE REDUCTION OPPORTUNITIES**
For each opportunity, provide:
- Opportunity name
- Current state vs. target state
- Estimated annual savings at [X] units/month
- Implementation steps (numbered)
- Difficulty rating (Low / Medium / High)
- Risks or trade-offs to consider

Opportunities to evaluate (apply all that are relevant):
1. Packaging reduction -- can dimensional weight be reduced to drop a size tier?
2. SIPP eligibility -- does the product qualify to ship in its own packaging without an Amazon box?
3. Category reassignment -- is the product misclassified in a higher-referral-fee category?
4. Low Price FBA program -- does the product qualify (selling price under $10)?
5. Storage turn improvement -- what inventory reduction would meaningfully cut monthly storage cost?

**SECTION 4 -- PRIORITY ACTION LIST**
Rank the opportunities by estimated annual savings (highest first) and give one next step for each.

PASTE YOUR DATA BELOW. Include: product name, ASIN (optional), selling price, product category, unit dimensions (L x W x H in inches), unit weight (oz or lbs), average monthly unit sales (if known), average days of inventory held in FBA (if known). [YOUR DATA HERE]
What you'd paste after the divider
Product: Silicone Baking Mat Set (2-pack)
ASIN: B09XXXXXX
Selling price: $24.99

01

Pull your exact dimensions and weights from the "Manage Inventory" shipping template or a recent FBA inbound shipment -- carrier-measured weights are the most accurate input.

02

Use Amazon's FBA Revenue Calculator in Seller Central alongside this prompt to cross-check the fee totals; the calculator reflects real-time fee tables.

03

Run this analysis quarterly -- Amazon adjusts fees each January and sometimes mid-year, so an opportunity that was marginal at the last review may now be worthwhile.

What does the Amazon Fee Analyzer prompt do?
This prompt breaks down every FBA fee layer for a specific product -- referral fee, fulfillment fee, and storage -- then identifies concrete opportunities to reduce your total fee burden through packaging changes, product right-sizing, or category re-evaluation. Use it whenever a product's margin is tighter than expected or you are planning a new product launch.
What data do I need to use this prompt?
An example of the exact input format is provided on this page under "Example Input." Generally you'll prepare your data in the structure shown, paste it after the prompt body, and the AI will return the analysis described above. If you're missing any inputs, the prompt will ask you what it needs.
How long does this take to set up?
Setup time for this prompt is 30-60 mins. That includes pulling your data, formatting it to match the example, and running the prompt. Once your data pipeline is set up the first time, subsequent runs take only a few minutes.
Which AI tool should I use this with?
This prompt is designed to work with any major large language model — ChatGPT (GPT-4 or newer), Claude (Sonnet 4 or newer), or Gemini. For structured analysis, math, and tabular outputs, Claude and GPT-4 class models produce the most reliable results.
Does this prompt work for Shopify or other platforms?
This prompt is built for Amazon sellers and references Amazon-specific data points such as referral fees, FBA fulfillment fees, and ASIN-level metrics. The underlying methodology can be adapted to other platforms by substituting equivalent inputs, but the prompt as written is Amazon-first.
What skill level is required to use this prompt?
This prompt is rated intermediate. Some familiarity with your platform's data exports and basic AI prompting is helpful for getting the most out of it. Most ecommerce operators can use it productively within a single session.
Is this prompt free to use?
Yes. Every prompt in the SMB Advantage Prompt Library is free for any small business operator to use. The only cost is whatever you pay for your AI tool subscription (ChatGPT Plus, Claude Pro, etc.).
