Amazon FBA Fee Calculator
What Is an Amazon FBA Fee Calculator?
An Amazon FBA (Fulfillment by Amazon) fee calculator is a free online tool that helps sellers estimate the total cost of using Amazon's fulfillment services. When you sell products through FBA, Amazon handles storage, picking, packing, and shipping your products to customers. However, these services come with various fees that can significantly impact your profit margins. Understanding exactly what Amazon charges is essential before launching any product on the platform.
Understanding FBA Fee Structure
FBA fees fall into three main categories. First, fulfillment fees cover the cost of picking, packing, and shipping your product. These range from $3.22 for small standard items under 6 ounces to $8.05 for oversize products. The fee increases with weight and size tier. Second, referral fees are a percentage of the sale price, typically ranging from 8% to 17% depending on the product category. Electronics generally carry an 8% referral fee, while clothing items may be 17%. Third, monthly inventory storage fees are charged per cubic foot, ranging from $0.75 in standard months to $2.40 during peak season (October-December).
| Fee Type | Rate | Notes |
|---|---|---|
| Fulfillment (Standard-Small) | $3.22 | Up to 6 oz |
| Fulfillment (Standard-Medium) | $4.25 | 6-12 oz |
| Fulfillment (Large) | $6.50 | 1-2 lbs |
| Fulfillment (Oversize) | $8.05+ | Over 2 lbs |
| Referral Fee | 8-17% | By category |
| Storage (Standard) | $0.75/cuft/mo | Jun-Sep |
| Storage (Peak) | $2.40/cuft/mo | Oct-Dec |
| Long-term Storage | $6.90/cuft | After 365 days |
Standard vs. Oversize Items
Amazon classifies products into different size tiers with corresponding fee structures. Standard-size items fit within an 18-inch package boundary. Large standard items exceed this but weigh under 50 pounds. Oversize items exceed either the 18-inch boundary or the 50-pound weight threshold, and incur substantially higher fulfillment fees. Knowing your size tier before launching a product is critical for accurate margin calculations.
Long-Term Storage Fees Warning
One of the biggest hidden costs for FBA sellers is long-term storage. Amazon charges $0.75 per cubic foot per month for items stored over 180 days, and an additional $6.90 per cubic foot for items sitting in warehouses for over a year. These fees can quickly erode profit margins on slow-moving inventory. Regularly monitoring your inventory age and removing stagnant stock before the 180-day threshold is a key FBA best practice.
