Example Calculation
Let’s look at a practical example:

- Quantity: 10
- Selling Price: $70
- Buy Commission: 2%
- Sell Commission: 3%
- Other Fees: $20
Step 1: Purchase Cost
$50 × 10 = $500
Buy Commission = $10
Total Purchase = $510
Step 2: Selling Revenue
$70 × 10 = $700
Sell Commission = $21
Total Revenue = $679
Step 3: Total Fees
$10 + $21 + $20 = $51
Step 4: Net Profit
$679 − $510 − $20 = $149
Step 5: ROI
($149 ÷ $510) × 100 ≈ 29.21%
Step 6: Profit Margin
