How to Use the Amazon FBA Packaging Optimizer

- Choose an analysis mode and enter current package dimensions and weight.
- Select product category and selling-price range for fee lookup.
- Click Analyze fee-saving opportunities and review representative options.
Analysis Modes
- Quick analysis — preset compression bands (~5%, ~15%, or ~30%) for fast screening.
- Compare a new package — enter a supplier quote or sample size and view the Supplier proposal card.
- Advanced exploration — set minimum feasible dimensions, search steps, and a result limit.
Key Results
- Risk level reflects how aggressively a candidate shrinks volume compared with your current package—it is not a safety certification.
- Representative options are curated candidates such as Easiest change, Recommended balance, and Maximum theoretical saving—not an exhaustive list.
- Theoretical savings show modeled per-unit fee differences; net saving subtracts packaging cost you enter and is not final net profit.
Frequently Asked Questions
Which analysis mode should I use?
Start with Quick analysis for broad screening. Use Compare a new package when you have a specific supplier size. Choose Advanced exploration when you need custom minimum dimensions and search step control.
What does the risk level mean?
Risk summarizes how aggressively a candidate shrinks volume compared with your current package. Higher reduction yields higher risk labels—it highlights implementation caution, not a formal safety rating.
Are suggested package sizes guaranteed?
No. Candidates are analytical starting points. Confirm product fit, protection, labeling, customer experience, and Amazon measurements before production.
Should I use packaged dimensions?
Always use finished packaged dimensions—the outer carton or mailer ready for FBA inbound. Bare product dimensions omit materials that Amazon includes in fulfillment measurement.
