How to Use the Amazon FBA Profit Calculator
Succeeding as an Amazon seller requires a deep understanding of your numbers. This Amazon FBA Profit Calculator helps you peel back the layers of Amazon's fee structure to see what actually ends up in your bank account.
Step 1: Selling Price – Enter the price you intend to list the item for on Amazon.com.
Step 2: Product Cost (COGS) – This is the "Land Cost" per unit. It includes the manufacturing cost from your supplier.
Step 3: Shipping to Amazon – Calculate how much it costs to ship one unit from your warehouse or supplier to Amazon's fulfillment centers.
Step 4: Referral Fee – Amazon charges a percentage for every item sold. For most categories, this is 15%.
Step 5: FBA Fulfillment Fee – This is the fee Amazon charges to pick, pack, and ship your item. It depends on the size and weight of your product.
Example Calculation
Imagine you are selling a yoga mat:
- Selling Price: $40.00
- Product Cost: $10.00
- Shipping to Amazon: $2.00
- Referral Fee (15%): $6.00
- FBA Fee: $7.50
- Marketing (PPC): $3.00
In this scenario, your total expenses are $28.50 ($10+$2+$6+$7.50+$3). Your Net Profit is $11.50, with a Profit Margin of 28.75% and an ROI of 115% (Profit / Product Cost).
Important Metrics Explained
Net Margin: This is your profit divided by the selling price. A "good" margin for FBA is typically between 20% and 30%.
ROI (Return on Investment): This calculates how much money you make relative to the money you spent on inventory. If you spend $1,000 on inventory and make $1,000 in profit, your ROI is 100%.
