Which fee schedule does this use?

The calculator uses Amazon's 2024 US FBA fee schedule for standard and oversize items. Apparel and footwear categories carry a higher referral fee; the tool accounts for that when the relevant category is selected.

Does this include the monthly storage fee?

No. FBA storage fees depend on how long inventory sits in Amazon's warehouse and vary by month (January–September vs October–December). Storage is excluded because it is variable; you can add it manually to your cost field.

What is the referral fee?

Amazon charges a referral fee as a percentage of the item's sale price (including shipping charged to the buyer). Most categories are 8–15%. This tool applies the standard rate for the selected category.

What counts as a "Small Standard" item?

Small Standard items weigh up to 16 oz and fit within 15 × 12 × 0.75 inches. Anything heavier or larger moves to Large Standard, then to the oversize tiers.

Are these fees exact?

This is an estimate. Amazon's actual fees depend on the precise dimensional weight, category sub-rules, and any active promotional fee rates. Always verify with Amazon's official Revenue Calculator before making sourcing decisions.
