An options profit calculator helps you understand the profit or loss of a call or put option at expiration based on the strike price, premium, and stock price. Whether you are buying calls to speculate on upside or selling puts to generate income, this free tool shows your break-even price, maximum profit, maximum loss, and a visual P&L chart across a range of stock prices.

How to Use This Options Profit Calculator
Options trading can be complex, but understanding your profit and loss at expiration is the essential foundation. This options profit calculator strips away the noise and shows you the exact payoff for any call or put option based on the stock price at expiration. Whether you are evaluating a speculative call, hedging with a put, or selling options for premium income, this tool gives you instant clarity on your risk and reward.
Step 1: Choose Your Option Type and Strategy
Select whether you are trading a Call (right to buy) or a Put (right to sell). Then choose your strategy: Long means you are buying the option and paying the premium, while Short means you are selling the option and collecting the premium. Each combination has a distinct risk profile — a long call has unlimited upside with limited risk, while a short call has limited profit potential but theoretically unlimited risk.
Step 2: Enter the Strike Price and Premium
The strike price is the price at which the option gives you the right to buy (call) or sell (put) the underlying stock. The premium is the per-share cost of the option contract. For example, if a call option with a $100 strike costs $5 per share, your total cost per contract is $500 (since each contract covers 100 shares). These two values determine your break-even point and maximum risk.
Step 3: Set the Number of Contracts and Stock Price
Enter how many contracts you are trading and the stock price you expect at expiration. The calculator will show your total P&L accounting for all contracts. You can adjust the stock price to explore different scenarios and see how your profit or loss changes at various price levels. Each contract multiplies your per-share result by 100.
Step 4: Read the P&L Chart and Reference Table
The interactive chart plots your profit and loss across a range of stock prices, with green areas showing profit and red areas showing loss. The break-even point is marked clearly. Below the chart, the reference table shows your exact P&L at five key price points, including intrinsic value, per-share P&L, total dollar P&L, and return on risk. Use this options profit calculator to compare different strikes and premiums before placing your trade.
Understanding the Results
The summary cards at the top show four critical numbers: your P&L at the entered stock price, the break-even price, maximum profit potential, and maximum loss exposure. The strategy description explains the risk profile in plain language. All calculations assume you hold the option to expiration — before expiration, factors like time decay and implied volatility also affect the option price. This calculator provides the clear, at-expiration foundation that every options trader needs.

FAQ
Is this options profit calculator free?
Yes, this options profit calculator is completely free with no hidden fees, no signup, and no usage limits. You can run unlimited calculations for calls, puts, long, and short strategies. Everything runs in your browser.
Is my data safe?
Absolutely. All calculations run entirely in your browser using client-side JavaScript. Your options data is never sent to any server or stored in any database. You can verify this by disconnecting from the internet and the calculator will still work.
How is the break-even price calculated for options?
For a long call, the break-even price is the strike price plus the premium paid. For a long put, it is the strike price minus the premium paid. Short options have the same break-even points. At this stock price at expiration, your total profit or loss is exactly zero.
What is the difference between a long and short option?
A long option means you bought (purchased) the option contract, paying the premium upfront. A short option means you sold (wrote) the option, receiving the premium. Long options have limited risk but require the stock to move favorably. Short options collect premium but carry potentially unlimited risk for calls.
Why does this calculator only show profit at expiration?
This calculator focuses on the expiration payoff because it provides a clear, precise picture of your profit or loss. Before expiration, option prices are also affected by time decay, implied volatility, and other Greeks, which add complexity. The expiration payoff is the foundation for understanding any options strategy.
How are options profits calculated per contract?
Each standard options contract represents 100 shares of the underlying stock. Your total premium cost or income is the per-share premium multiplied by 100, then multiplied by the number of contracts. Profit and loss at expiration follow the same multiplication, so a $1 move beyond break-even equals $100 per contract.
What does unlimited max profit or max loss mean?
For a long call, the stock price can theoretically rise without limit, so max profit is unlimited. For a short call, you face unlimited loss if the stock rises far above the strike. In practice, stocks do have practical limits, but these terms indicate there is no mathematical cap on the potential outcome.
