Amazon FBA fee calculator FAQ
Common questions about Amazon FBA fees, referral percentages, storage, and how to calculate net profit.
What is the Amazon FBA fee calculator?
An Amazon FBA fee calculator estimates the total seller fees Amazon charges per sale - referral fee, fulfillment fee, and monthly storage fee - based on your product category, dimensions, and weight. It lets you preview your net profit before listing the item on Amazon.
How are Amazon FBA fulfillment fees calculated?
Amazon FBA fulfillment fees are based on the product's size tier (Small Standard, Large Standard, Large Bulky, Extra Large) and unit weight. Smaller, lighter items pay lower flat fees, while items above 3 lb add a per-pound surcharge. The calculator picks the size tier from your dimensions and weight, then applies Amazon's 2024-2025 published rate for that bucket.
What is the Amazon referral fee?
The Amazon referral fee is a percentage Amazon takes from each sale based on the product category. It is charged on the sale price (including shipping in most categories) with a $0.30 per-item minimum. Most categories sit at 15%, while consumer electronics is 8% and jewelry can reach 20%.
How much does Amazon FBA storage cost per month?
Amazon FBA monthly storage fees in 2025 are roughly $0.78 per cubic foot for standard-size items and $0.56 per cubic foot for oversize items from January to September. From October to December (peak), rates jump to about $2.40 per cubic foot for standard and $1.40 for oversize. Long-term storage surcharges may apply to inventory aged 271+ days.
How can I lower my Amazon FBA fees?
You can lower Amazon FBA fees by reducing product packaging dimensions to land in a smaller size tier, trimming unit weight to drop into a cheaper fulfillment bucket, picking a category with a lower referral percentage when possible, and rotating inventory faster so you avoid long-term storage surcharges.
