How to Use the Amazon FBA Profit Calculator
Scaling a business on Amazon requires more than just high sales volume; it requires healthy margins. Our Amazon FBA Profit Calculator helps sellers account for every hidden fee, from the standard 15% referral fee to the variable fulfillment costs associated with item size and weight.
Understanding the Metrics
Selling Price: The list price of your item on Amazon.com.
COGS (Cost of Goods Sold): The raw manufacturing or wholesale cost per unit.
FBA Fees: The pick-and-pack fee Amazon charges to ship your product. This depends on the product's tier (Small Standard, Large Standard, etc.).
Referral Fee: Usually 15% for most categories, this is the commission Amazon takes for bringing you the customer.
ROI (Return on Investment): This calculates how much profit you make relative to your product cost. For example, if you spend $10 to make $10 profit, your ROI is 100%.
FBA Profit Example Calculation
Suppose you sell a product for $50.00. Your manufacturing cost is $12.00, and shipping to the Amazon warehouse is $2.00. Amazon's referral fee (15%) is $7.50, and the FBA fulfillment fee is $5.50. You spend an average of $5.00 per unit on PPC advertising.
Many sellers forget to include PPC Spend and Inbound Shipping. If your Amazon dashboard says you made $10,000 this month, but you spent $4,000 on ads and $3,000 on new inventory, your actual take-home pay is significantly lower. Use this calculator regularly to ensure your PPC bids aren't eating your entire profit margin.
