🧭 Step-by-Step: How to Use the Long Options Calculator

Here’s a simple guide to using the Long Options Calculator effectively:

Step 1: Select Your Option Type

Choose between:

• Long Call – You’re buying the right to purchase a stock at a specific price.
• Long Put – You’re buying the right to sell a stock at a specific price.

Step 2: Enter the Underlying Price at Purchase

This is the current market price of the stock when you open the trade (e.g., $100).

Step 3: Enter the Strike Price

The strike price is the price at which you have the right to buy (call) or sell (put) the stock (e.g., $105).

Step 4: Input the Option Premium

This is the price you pay per contract to buy the option. It represents your maximum possible loss (e.g., $2.50).

Step 5: Set Number of Contracts

Each contract typically represents 100 shares, but you can modify this value as needed.

Step 6: Enter the Underlying Price at Expiry

Input the expected or actual stock price at the expiration date (e.g., $110).

Step 7: Click “Calculate”

Once you hit the “Calculate” button, the calculator processes your data and displays detailed results—showing gross and net profit/loss, break-even point, maximum profit, maximum loss, and return on risk.

Step 8: View and Share Results

You can copy or share your results directly with other traders or on social media for learning and discussion.

💡 Practical Example: Understanding a Long Call Trade

Let’s walk through a realistic example of a long call trade.

• Option Type: Long Call
• Underlying Price: $100
• Strike Price: $105
• Option Premium: $2.50
• Contracts: 1
• Shares per Contract: 100
• Final Price (at expiry): $110

➤ Calculation Results:

• Gross Profit/Loss: $500
• Net Profit: $250
• Maximum Loss: $250
• Break-Even Point: $107.50
• Return on Risk: +100%

Interpretation:
If the stock price rises to $110, you make a net profit of $250 after accounting for the premium. Your maximum loss is limited to the premium you paid ($250), and your profit potential is unlimited as the stock continues to rise.
