How to Use the Amazon FBA Profit Calculator

Success on Amazon depends on understanding your unit economics. This calculator helps Amazon sellers determine if a product is viable after accounting for the various fees associated with the Fulfillment by Amazon (FBA) program. To get an accurate result, you need to account for your manufacturing costs, shipping, and the mandatory Amazon commissions.

Key Metrics Explained

Referral Fee: This is the commission Amazon takes for every item sold. For most categories, this is 15%, but it can range from 8% to 45% depending on the niche.

FBA Fulfillment Fee: This covers the cost of picking, packing, and shipping your product to the customer. It is determined by the weight and dimensions of your product.

Net Margin: This tells you what percentage of your total revenue is actual profit. A healthy FBA margin is typically between 15% and 25% after all expenses.

ROI (Return on Investment): This measures the efficiency of your capital. For example, a 100% ROI means you doubled your money (you spent $10 to make $10 profit).

Example Calculation

Imagine you are selling a yoga mat for $40.00. Your manufacturing cost is $10.00, and shipping it to an Amazon warehouse costs $2.00 per unit. Amazon charges a 15% referral fee ($6.00) and an FBA fulfillment fee of $7.50. After a small storage fee of $0.50, your total costs are $26.00. Your net profit would be $14.00 per unit, resulting in a 35% margin and a 140% ROI.
