How This Works

This calculator estimates every per-unit fee that Amazon charges FBA sellers. Actual fees may vary based on your account status, enrollment programs (e.g., FBA New Selection), and Amazon's latest fee schedule.

Referral fees are a percentage of the selling price and vary by category. Amazon applies a minimum referral fee of $0.30.

FBA fulfillment fees depend on the product's size tier, determined by the packaged dimensions and weight. The three dimensions are sorted longest-to-shortest to classify the tier.

Monthly storage fees are charged per cubic foot of space your inventory occupies. Rates increase in Q4 (Oct-Dec) due to peak-season demand.

Inbound placement fees apply when Amazon distributes your inventory across multiple fulfillment centers. Standard-size items are charged ~$0.27/unit and large bulky items ~$1.58/unit.

Low-inventory-level fees (~$0.32/unit) are charged when you keep fewer than 28 days of supply in FBA warehouses.

Frequently Asked Questions

Amazon charges several fees for FBA sellers: a referral fee (percentage of the selling price that varies by category), an FBA fulfillment fee (based on size tier and weight), monthly storage fees (based on cubic footage, higher in Q4), inbound placement fees, low-inventory-level fees if you keep less than 28 days of supply, return processing fees when customers return items, and a closing fee for media products.
The referral fee is a percentage of the total selling price (including the item price and any shipping or gift-wrap charges). The rate depends on the product category. Most categories are charged 15%, Electronics 8%, Clothing & Accessories 17%, Jewelry 20%, and Automotive 12%. Amazon also enforces a minimum referral fee of $0.30 per item.
The FBA fulfillment fee covers picking, packing, shipping, customer service, and returns handling. It is determined by the product's size tier (Small Standard, Large Standard, Large Bulky, or Extra-Large) and shipping weight. Smaller, lighter products have significantly lower fees.
Amazon increases monthly storage fees from October through December (Q4) because warehouse space is in high demand during the holiday season. Standard-size storage jumps from roughly $0.87 per cubic foot to $2.40 per cubic foot, and oversized storage rises from $0.78 to $2.40 per cubic foot.
You can reduce fees by optimizing package dimensions to qualify for a lower size tier, maintaining at least 28 days of inventory to avoid the low-inventory-level fee, sending inventory to a single inbound location to reduce placement fees, keeping return rates low with accurate listings, and choosing the right product category. Selling higher-priced items also lowers fees as a percentage of revenue.
