Practical Example of Seller Central Calculation
Suppose you want to sell a kitchen product on Amazon.
Product Details
- Selling Price: $40
- Product Cost: $12
- Shipping Cost: $3
- Amazon Referral Fee: 15%
- FBA Fee: $6
- Advertising Cost: $4
Calculation
Referral Fee
$40 ร 15% = $6
Total Expenses
$12 + $3 + $6 + $6 + $4 = $31
Net Profit
$40 โ $31 = $9
Profit Margin
($9 รท $40) ร 100 = 22.5%
ROI
($9 รท $12) ร 100 = 75%
