Selling on Amazon through their Fulfillment by Amazon (FBA) program offers convenience but comes with various fees. This calculator helps estimate these costs based on your product's selling price, weight, and dimensions. Understanding these fees is crucial for accurate profit margin calculation and pricing strategy.
Key Amazon FBA Fees Included:
Referral Fee: A percentage of the total sales price, varying by product category.
FBA Fulfillment Fee: Covers picking, packing, and shipping your product to the customer. This fee is primarily determined by the product's weight and dimensions.
How the Fees are Calculated:
This calculator uses the following logic:
Referral Fee Calculation:
Currently, the standard referral fee is 15% of the total sales price. For certain categories, there might be a minimum referral fee (e.g., $0.30 for items priced under $15).
Referral Fee = Selling Price * 0.15 (with a minimum, if applicable)
FBA Fulfillment Fee Calculation:
Amazon categorizes products into fulfillment fee tiers based on size and weight. This calculator simplifies this by using estimated average rates based on common product dimensions and weights. The actual fee can vary based on the exact size tier (e.g., Standard-Size vs. Oversize) and shipping weight.
We will estimate a base fulfillment fee and add a per-pound surcharge if the weight exceeds a certain threshold.
Note: This is a simplified estimation. For precise fees, always refer to Amazon's official FBA fee structure, as it can change and depends on the exact shipping weight and dimensional weight calculation by Amazon.
Total Estimated Fees:
The sum of the Referral Fee and the FBA Fulfillment Fee.
Total Fees = Referral Fee + FBA Fulfillment Fee
Factors Affecting Fees:
Product Category: Dictates the referral fee percentage.
Selling Price: Directly impacts the referral fee and potentially minimum referral fees.
Product Weight & Dimensions: Crucial for determining the FBA fulfillment fee. Larger or heavier items incur higher fulfillment costs. Amazon also uses 'dimensional weight' which can increase fees if the packaging is bulky relative to its actual weight.
Storage Fees & Other Services: This calculator does not include monthly inventory storage fees, long-term storage fees, or fees for other services like removal orders, returns processing, or specialized prep services, which can add to your overall costs.
Example Scenario:
Let's say you're selling a product for $30.00. It weighs 0.8 kg and has dimensions of 22cm x 17cm x 12cm.
Referral Fee: $30.00 * 15% = $4.50
Estimated FBA Fulfillment Fee: Based on typical small standard-size items, let's estimate a base fee of $3.50 plus $0.40 per kg over 0.5kg (0.3kg * $0.40 = $0.12). Total fulfillment fee = $3.50 + $0.12 = $3.62. (Note: This is a simplified example; actual Amazon fees depend on specific tiers).
Total Estimated Fees: $4.50 (Referral) + $3.62 (Fulfillment) = $8.12
This means your estimated profit before product cost would be $30.00 – $8.12 = $21.88. Always verify these figures with Amazon's latest fee schedules.
