How to Use the Amazon FBA Profit Calculator
Selling on Amazon can be highly lucrative, but only if you understand your numbers. Many new sellers focus solely on the "Selling Price" and "Product Cost," forgetting the various fees that Amazon subtracts from every sale. This calculator helps you uncover your true net profit.
Key Metrics Explained
Selling Price: The final amount the customer pays for your item on Amazon.
Product Cost (COGS): The total cost to manufacture or purchase one unit from your supplier.
Referral Fee: Amazon's "commission" for selling on their platform. This is usually 15% for most categories but can range from 8% to 45%.
Fulfillment Fee (FBA Fee): The cost for Amazon to pick, pack, and ship your item to the customer. This is based on the size and weight of your product.
ROI (Return on Investment): This shows how much profit you made relative to your initial investment. A 100% ROI means you doubled your money.
Real-World Example Calculation
Let's say you are selling a "Yoga Mat" with the following numbers:
Selling Price: $35.00
Product Cost: $8.00
Shipping to Amazon: $1.50
Referral Fee (15%): $5.25
FBA Fee: $6.50
Storage/Misc: $0.50
In this scenario, your total expenses are $21.75. Your Net Profit is $13.25 per unit, with a Profit Margin of 37.8% and an ROI of 139.5%.
Strategies to Improve Your FBA Margins
If your margins are slim (below 20%), consider these strategies:
Reduce Packaging Size: Moving a product from "Large Standard" to "Small Standard" size tier can save you dollars in FBA fulfillment fees.
Bulk Shipping: Use sea freight instead of air freight to lower your "Shipping to Amazon" cost per unit.
Negotiate with Suppliers: As your volume grows, negotiate a 5-10% discount on unit costs.
Optimize PPC Spend: High advertising costs can quickly eat into your organic profits.
