How to Use the Amazon FBA Profit Calculator
Success on Amazon hinges on understanding your numbers. The Amazon FBA Profit Calculator helps sellers determine whether a product is a "winner" or a "drain" on resources after all fees are deducted. Here is a breakdown of the key inputs:
Sale Price: The final price the customer pays for your product.
Product Cost (COGS): The manufacturing or wholesale cost of the item including shipping from the factory.
Referral Fee: Amazon's commission for selling on their platform (typically 15% for most categories).
FBA Fulfillment Fee: The cost Amazon charges to pick, pack, and ship your item. This varies by weight and dimension.
Shipping to Amazon: The cost per unit to send your inventory to an Amazon fulfillment center.
Example Calculation
Imagine you are selling a yoga mat for $40.00. Your manufacturing cost is $10.00. Amazon takes a 15% referral fee ($6.00) and an FBA fulfillment fee of $7.50. You spend $1.00 per unit on shipping to Amazon and $2.00 on advertising (PPC).
New sellers often make the mistake of only looking at the "Top Line" (Revenue). However, with rising shipping costs and PPC competition, a product with high revenue could actually be losing money. A healthy FBA business typically aims for a profit margin above 20% and an ROI above 100% to ensure sustainability and cover unexpected costs like returns or price wars.
