This calculates Amazon FBA fees and profit margins based on product dimensions, weight, and pricing. It automatically classifies items into the correct 2024 size tier (small standard through special oversize), breaks down fulfillment fees, storage costs, and referral fees by category, then shows you gross margin, net margin, and ROI. The optimization tips are helpful if you're trying to shave costs by tweaking packaging dimensions or managing inventory aging. It's straightforward if you're sourcing products and need to know whether the unit economics actually work before committing to inventory. Supports both JSON input and interactive mode, with Chinese language output available.
