Enter the strike, the premium paid per share, the number of contracts and a stock price at expiration to see the payoff, profit or loss, break-even and maximum loss, with the arithmetic shown. ## Key points - **Break-even shown:** Strike plus premium per share: the stock price at expiration where the call’s payoff equals the premium paid. - **Maximum loss:** The premium paid, premium × 100 × contracts, which is the loss if the call expires at or below the strike. - **Scenario table:** Compare the result at several stock prices around the strike, not only one target. ## Call option profit formula At expiration, a long call is worth max(0, stock price - strike) per share. Multiply that by 100 shares per standard contract and by the number of contracts, then subtract the premium paid (premium × 100 × contracts). The result is the profit or loss at expiration, before commissions and fees. The premium input is per share, as equity option prices are quoted. The call side is preset here; the combined options profit calculator switches between calls and puts. - Call value at expiration = max(0, price - strike) × 100 × contracts. - Profit or loss = call value - premium × 100 × contracts. - Break-even at expiration = strike + premium. - Maximum loss = premium × 100 × contracts. ## Worked example: call profit at expiration Take one call contract with a $100.00 strike, bought for $2.50 per share, and a stock price of $110.00 at expiration. Each line shows the formula, then the numbers, then the result. The calculator above opens with these inputs and displays the same results. At or below $100.00 at expiration, the call expires worthless and the loss is the full $250.00 premium. Above $102.50, the expiration payoff is larger than the premium paid. - Break-even = strike + premium = $100.00 + $2.50 = $102.50 - Maximum loss = premium × 100 × contracts = $2.50 × 100 × 1 = $250.00 - Call value at $110.00 = max(0, price - strike) × 100 × contracts = max(0, $110.00 - $100.00) × 100 × 1 = $1,000.00 - Profit or loss at $110.00 = call value - maximum loss = $1,000.00 - $250.00 = $750.00 ## What this calculator leaves out The payoff is calculated at expiration. Before expiration, a call also carries time value, which depends on implied volatility, time remaining, interest rates and dividends, so a position closed early can show a different gain or loss than this model at the same stock price. It covers a long call only: bought, not sold. Short options and spreads have different maximum-loss, margin and assignment rules. Commissions, fees, slippage and nonstandard contract multipliers are excluded. The calculator checks arithmetic; it does not estimate how likely a price is or recommend a trade. ## Frequently asked questions ### How do you calculate call option profit? At expiration, take max(0, stock price - strike), multiply it by 100 and by the number of contracts, then subtract the premium paid × 100 × contracts. With a $100.00 strike, a $2.50 premium and the stock at $110.00, one contract is worth $1,000.00 and the profit is $750.00. ### What is the break-even price for a call option? At expiration, the strike plus the premium paid per share. A $100.00 call bought for $2.50 breaks even at $102.50, before commissions and fees. ### What is the maximum loss on a long call? The premium paid: premium × 100 × contracts, or $250.00 for one $2.50 contract. That is the loss if the stock is at or below the strike at expiration. ### What is a call option’s payout at expiration? Its intrinsic value: max(0, stock price - strike) × 100 per contract. The profit is that payout minus the premium paid. In the expiration formula the payout has no fixed upper limit, because it grows with the stock price above the strike. ### How much does one call option contract cost? A standard U.S. equity option covers 100 shares and its premium is quoted per share, so one contract costs the premium × 100. A $2.50 premium costs $250.00 per contract before commissions and fees. Adjusted contracts can use a different multiplier, so check the contract specification. ### Why can my actual call P/L differ from this calculator? Before expiration, a call still has time value that moves with implied volatility, time remaining, rates and dividends. This calculator shows the expiration payoff only and excludes commissions, fees and slippage. ## Related CaymanBot resources - [Put option profit calculator](https://caymanbot.com/put-option-profit-calculator) - [Options profit calculator](https://caymanbot.com/options-profit-calculator) - [Options position size calculator](https://caymanbot.com/options-position-size-calculator) - [Options expected move calculator](https://caymanbot.com/options-expected-move-calculator) Market data, modeled analytics, calculators and public-filing summaries are informational.
