Options Profit Calculator

How to Use the Options Profit Calculator

Select whether you are buying a call or put option, then enter the strike price, premium per share, current underlying stock price, and the number of contracts. Each contract represents 100 shares. The calculator instantly shows your total profit or loss, break-even price, return on investment, and maximum risk.

This calculator models the profit and loss at expiration for long (bought) options. It helps you quickly evaluate whether a trade setup offers a favorable risk-reward ratio before committing capital. Understanding your maximum loss and break-even price before entering a trade is a fundamental principle of options risk management.

Understanding Options Profit and Loss

For a call option, you profit when the underlying price exceeds the strike price by more than the premium paid. Your break-even is the strike price plus the premium. Maximum loss is limited to the total premium paid, while maximum profit is theoretically unlimited since stock prices can rise indefinitely.

For a put option, you profit when the underlying price drops below the strike price by more than the premium paid. Your break-even is the strike price minus the premium. Maximum loss is the total premium paid, and maximum profit is capped at the strike price minus the premium (multiplied by shares) since a stock can only drop to zero.

Key Options Terminology

An option is in the money when it has intrinsic value: for calls, when the stock is above the strike; for puts, when the stock is below the strike. Out of the money means the option has no intrinsic value. The premium is the price you pay for the option contract and represents your maximum risk as a buyer.

Options Risk Management

Never risk more than you can afford to lose. Options can expire worthless, meaning you lose 100% of your premium. Consider position sizing, which means limiting any single trade to a small percentage of your portfolio. Always know your maximum loss before entering a trade, and consider setting price alerts at your break-even level.

Frequently Asked Questions

How do you calculate profit on a call option?

Profit per share equals the underlying price minus the strike price minus the premium. Multiply by 100 shares per contract and the number of contracts for total profit.

What is the maximum loss when buying options?

Your maximum loss is the total premium paid: premium per share times 100 shares per contract times the number of contracts.

What does in the money mean?

A call is in the money when the stock price exceeds the strike. A put is in the money when the stock is below the strike. In-the-money options have intrinsic value.

How is the break-even price calculated?

For calls: strike price plus premium. For puts: strike price minus premium. At break-even, you recover your entire premium with zero profit or loss.

How do you calculate profit on a put option?

Profit per share equals the strike price minus the underlying price minus the premium. Multiply by shares for total profit. If the stock is above the strike, you lose the premium.
