Example Calculation

Let’s look at a realistic example.

Product Details:

Selling Price: $30
Product Cost: $10
Shipping Cost: $3
FBA Fee: $6
Referral Fee: 15%
Units Sold: 100

Step 1: Total Revenue

Revenue = Selling Price × Units Sold

Revenue = $30 × 100
Revenue = $3,000

Step 2: Referral Fee

Referral Fee = 15% of $30 = $4.50 per unit

Total Referral Fee = $4.50 × 100 = $450

Step 3: FBA Fees

FBA Fee per unit = $6

Total FBA Fees = $6 × 100 = $600

Total Amazon Fees = $450 + $600 = $1,050

Step 4: Total Cost

Product Cost = $10 × 100 = $1,000
Shipping Cost = $3 × 100 = $300

Total Cost = $1,000 + $300 + $1,050

Total Cost = $2,350

Step 5: Net Profit

Net Profit = Revenue – Total Cost

Net Profit = $3,000 – $2,350

Net Profit = $650

Step 6: Profit Margin

Profit Margin = (Profit ÷ Revenue) × 100

Profit Margin = (650 ÷ 3000) × 100

Profit Margin = 21.67%

This example shows how the calculator helps sellers determine profitability before launching a product.
