Example Calculation
Let’s understand how this calculator works with a real-life example:
- Buy Price: $50
- Sell Price: $65
- Shares: 100
- Broker Fee: $20
Step 1: Total Investment
= Buy Price × Shares
= 50 × 100
= $5,000
Step 2: Total Return
= Sell Price × Shares
= 65 × 100
= $6,500
Step 3: Profit
= Total Return − Investment − Fee
= 6,500 − 5,000 − 20
= $1,480
Step 4: Return Percentage
= (Profit ÷ Investment) × 100
= (1,480 ÷ 5,000) × 100
= 29.6%
Final Result: You made a profit of $1,480 with a 29.6% return.
