Example Calculation
Let’s understand how this works with a practical example:
- Buy Price per Share: $50
- Sell Price per Share: $70
- Number of Shares: 100
- Fees: $20
Step 1: Total Investment
= Buy Price × Shares
= 50 × 100
= $5,000
Step 2: Total Return
= Sell Price × Shares
= 70 × 100
= $7,000
Step 3: Net Profit
= Total Return − Investment − Fees
= 7,000 − 5,000 − 20
= $1,980
Step 4: ROI (%)
= (Profit ÷ Investment) × 100
= (1,980 ÷ 5,000) × 100
= 39.6%
So, your return on investment is 39.6%, which indicates a profitable trade.
