Example: Stock Options Calculation
Let’s look at a simple example.
Trade Details
Current Stock Price: $50
Strike Price: $55
Option Premium: $2
Contracts Purchased: 3
Expected Price at Expiration: $65
Step 1: Calculate Shares
Each contract represents 100 shares.
3 contracts × 100 = 300 shares
Step 2: Calculate Total Investment
Premium × Shares
$2 × 300 = $600
Step 3: Break-Even Price
Strike Price + Premium
$55 + $2 = $57
Step 4: Intrinsic Value
Expected Price – Strike Price
$65 − $55 = $10
$10 × 300 shares = $3000
Step 5: Profit
Intrinsic Value − Investment
$3000 − $600 = $2400 profit
This example shows how a relatively small options investment can generate larger returns if the stock moves in the expected direction.
