Understanding the Long Call Option Payoff Diagram
A long call option payoff diagram is a visual representation of the profit and loss at different stock prices at expiration. The diagram shows a hockey stick pattern: the position loses a fixed amount (the premium paid) when the stock is below the strike price, and profits increase linearly as the stock rises above the break-even point.
The long call is the most basic bullish options strategy. You buy the right to purchase shares at the strike price before expiration. If the stock rises above the strike price plus the premium paid (the break-even point), the position becomes profitable. If the stock stays below the strike at expiration, the option expires worthless and you lose the entire premium.
Maximum Loss: Premium paid (limited). Maximum Profit: Unlimited (stock can rise indefinitely). Break-Even: Strike Price + Premium Paid. Best used when you are bullish on the stock and expect a significant upward move.
Long Call Formulas
- 1Total cost = $5.00 × 100 shares = $500
- 2Break-even price = $100 + $5 = $105
- 3At $115: Intrinsic value = $115 - $100 = $15 per share
- 4Profit per share = $15 - $5 = $10
- 5Total profit = $10 × 100 = $1,000
- 6ROI = ($10 / $5) × 100 = 200%

When to Use a Long Call
- You are bullish on the stock and expect a significant price increase
- You want leveraged exposure with limited downside risk
- You want to participate in upside without owning shares outright
- You expect a catalyst (earnings, FDA approval, product launch) to drive the stock higher
- You want to risk a small amount (premium) for potentially large gains
Factors Affecting Long Call Profitability
Key Factors to Consider
While the maximum loss on a long call is limited to the premium paid, that is still 100% of your investment in the trade. Many long calls expire worthless. Only invest what you can afford to lose, and consider your probability of profit before entering the trade.
