How Options Profit Calculation Works

An option gives you the right (but not the obligation) to buy or sell a stock at a specific price (the strike price) before or at expiration. A call option profits when the stock goes up, while a put option profits when the stock goes down. The premium is the price you pay to buy the option — it represents your maximum loss if you're the buyer.

For a long call, your profit at expiration is: (Stock Price - Strike Price) × 100 shares per contract, minus the premium paid. For a long put, it's: (Strike Price - Stock Price) × 100 - premium. Short positions (selling options) reverse this: you collect the premium upfront but take on the obligation. Short calls have theoretically unlimited risk if the stock rises.

The break-even price is where your profit equals zero. For calls, it's the strike price plus the premium; for puts, it's the strike price minus the premium. Options are a leveraged instrument — small price movements can produce large percentage returns (or losses). For stock investment calculations, see the investment calculator, or for dividend income, try the dividend calculator.

Frequently Asked Questions

What is the difference between a call and a put?
A call option gives you the right to buy the underlying stock at the strike price. You profit when the stock rises above the strike price plus the premium. A put option gives you the right to sell at the strike price. You profit when the stock falls below the strike price minus the premium.
What does 'long' and 'short' mean in options?
Long means you bought the option (you paid the premium). Short means you sold the option (you received the premium). Long positions have limited risk (you can only lose the premium), while short call positions have theoretically unlimited risk.
How is the break-even price calculated?
For a call option: Break-even = Strike Price + Premium. For a put option: Break-even = Strike Price - Premium. At the break-even price, your profit is exactly zero — any movement beyond it is profit.
Why does one contract equal 100 shares?
Standard US stock options represent 100 shares per contract. This is set by the Options Clearing Corporation (OCC). So if an option costs $5 per share, one contract costs $500 total ($5 × 100 shares).
Does this calculator account for time decay (theta)?
This calculator shows profit/loss at expiration, when time value is zero and only intrinsic value remains. For mid-expiration analysis including Greeks (delta, theta, gamma, vega), you'd need an options pricing model like Black-Scholes.
