Understanding Amazon FBA Fees
Selling on Amazon through the Fulfillment by Amazon (FBA) program offers significant advantages, including access to Amazon's vast logistics network, Prime eligibility, and customer service. However, it comes with a set of fees that sellers must understand to accurately price their products and ensure profitability. This calculator helps estimate these essential FBA fees.
Key Amazon FBA Fees Explained:
Referral Fee: This is a fee charged on each item sold, regardless of the fulfillment method. It's a percentage of the total sales price (including shipping and any other charges). The percentage varies significantly by product category. For example, "Electronics" typically have a 15% referral fee, while "Books" have a 15% fee up to $10, then 8% on the remainder.
FBA Fulfillment Fee: This fee covers the cost of Amazon picking, packing, and shipping your order to the customer. It's primarily determined by the product's size and weight. Amazon categorizes products into different tiers (e.g., Standard-size, Oversize, Large Oversize) and has specific rates for each. Items requiring special handling (like Hazmat) may incur additional charges.
Monthly Inventory Storage Fee: FBA sellers pay a monthly fee to store their products in Amazon's fulfillment centers. This fee is based on the average daily volume (in cubic feet) of the inventory stored. Rates can also vary depending on the time of year (higher rates often apply during the peak holiday season, October-December) and whether the item is considered standard-size, oversize, or special handling.
Long-Term Storage Fee: If inventory remains in an Amazon fulfillment center for more than 365 days, it is subject to a long-term storage fee, in addition to the monthly storage fee.
Inbound Shipping Fees: While not directly calculated here, sellers must also account for the cost of shipping their products to Amazon's fulfillment centers.
This fee is based on the product's shipped weight (product weight + packaging) and dimensions. Amazon uses a tiered pricing structure based on size and weight categories. For this calculator, we use a simplified estimation based on product weight and a general assumption of packaging. Actual fulfillment fees are precisely determined by Amazon based on the final shipped package dimensions and weight.
FBA Fulfillment Fee = Base Fee (determined by size tier and weight) + Additional Weight Fee (if applicable)
Monthly Inventory Storage Fee:
This is calculated based on the average daily volume occupied by your inventory in cubic feet and the storage month. Standard rates apply for most of the year, with surcharges during peak season.
Monthly Storage Fee = Average Daily Volume (cubic feet) * Price per Cubic Foot (by month/size tier)
Example Calculation Logic for this Calculator:
Referral Fee: A fixed percentage is applied based on the selected category.
FBA Fulfillment Fee: This calculator uses a simplified model. For standard-size items, it estimates based on weight. For oversize items, a higher base fee is applied. Accurate calculation requires exact shipped dimensions and weight provided by Amazon.
Monthly Storage Fee: This calculator provides a rough monthly estimate using standard rates per cubic foot for standard-size items. It assumes an average daily volume derived from the product dimensions.
Using the FBA Fee Calculator:
To get the most accurate estimate:
Enter the exact selling price you plan to list your product for.
Accurately measure your product's dimensions (Length x Width x Height) in centimeters and its weight in kilograms including its packaging.
Select the correct product category as defined by Amazon.
Choose your intended fulfillment channel (FBA).
Remember, this calculator provides an estimate. Always refer to the latest Amazon FBA fee schedule for the most precise and up-to-date information, as fees can change.
