Options Profit Calculator

Most retail traders think a call option's profit is simply (Stock Price, Strike Price). That formula misses the premium you paid and the required max(0, …) floor, so an out-of-the-money long call would show a loss larger than the premium you actually risk. The correct calculation is: Profit = max(0, Underlying Price, Strike Price) × 100 × Contracts, Premium Paid, Commission. This options profit calculator takes your exact trade inputs and shows the net result at expiration.

Enter your option details below to see profit/loss, breakeven, maximum profit, and maximum loss for a single leg held to expiration. The tool models one position only; multi-leg strategies require summing leg results manually.

Inputs You Enter

Select option type (call or put) and position (long or short). Enter the strike price, premium per share, number of contracts, and stock price at expiration. One contract equals 100 shares. The calculator multiplies all per-share figures by this share count.

Commission

In Advanced Options, add the total commission per contract for opening and closing the trade. The tool subtracts this from your net profit (long positions) or deducts it from the credit received (short positions). If you skip it, the calculator shows the strategy result before broker fees.

Results You Get

Net profit/loss in dollars, total cost or credit received, option intrinsic value at expiration, return on investment (ROI), breakeven price, maximum profit, maximum loss, and a profit/loss chart across possible stock prices.

Enter a trade and see what it makes or loses at a given stock price at expiration. Use it before committing capital to check whether the potential return justifies the risk.

Every standardized option uses one of four formulas at expiration, defined in the OCC 'Characteristics and Risks of Standardized Options' (current edition). The max(0, …) floor is critical: an option cannot have negative intrinsic value, so out-of-the-money options return zero from the price move, not a negative number.

Long Call (Buy)

Profit = max(0, Stock Price, Strike Price) × 100 × Contracts, Premium Paid, Commission. You profit when the stock price rises above the strike plus your per-share costs.

Long Put (Buy)

Profit = max(0, Strike Price, Stock Price) × 100 × Contracts, Premium Paid, Commission. You profit when the stock price falls below the strike minus your per-share costs.

Short Call (Sell)

Profit = Premium Received, max(0, Stock Price, Strike Price) × 100 × Contracts, Commission. You profit if the stock stays below the strike; your maximum gain is the premium received.

Short Put (Sell)

Profit = Premium Received, max(0, Strike Price, Stock Price) × 100 × Contracts, Commission. You profit if the stock stays above the strike; your maximum gain is the premium received.

Each formula above is the core of a call option calculator or put option calculator. The distinction between long and short matters for risk: long positions cap loss at the premium, short positions have unlimited loss potential (short call) or loss capped at the strike price minus credit (short put).

Trade Entry

You buy one call option contract on ABC stock with a strike price of $55. The premium is $3 per share. One contract covers 100 shares, so the total premium is $3 × 100 = $300. You pay a $10 commission for the whole trade. Your total cost at entry is $300 + $10 = $310.

At Expiration

The stock price reaches $65. Your option is in the money.

• Step 1: Intrinsic value = max(0, $65 - $55) × 100 = $1,000.
• Step 2: Subtract total premium: $1,000 - $300 = $700.
• Step 3: Subtract commission: $700 - $10 = $690.

Net profit: $690. If the stock had stayed below $55, the intrinsic value would be zero, and your loss would be the premium plus commission ($310).

Verify With The Calculator

Enter: call option, long position, strike $55, premium $3, 1 contract, stock price $65, commission $10. The calculator shows net profit $690, breakeven $58.10, maximum loss $310.

The profit/loss chart plots net profit on the y-axis against stock price at expiration on the x-axis. For a long call, the line is flat at zero intrinsic value until the stock price passes the strike, then rises at a 45-degree angle. The breakeven point is where the line crosses zero profit. The chart helps you see the risk-reward profile: for a long call, losses are capped (the flat section below the strike), while gains are unlimited in theory.

The Cboe Options Institute strategy pages use these same payoff diagrams to illustrate multi-leg strategies. The single-leg diagram is the building block for more complex positions.

This tool models one option position held to expiration. It does not price the option before expiry, so you cannot use it to estimate early assignment value. It does not model early exercise of American-style options, which changes profit timing and dividend adjustments (see the OCC/Cboe early exercise material for those rules). Taxes, margin interest, and the bid-ask spread between the underlying's mid price and the broker's fill price are not included. Multi-leg strategies like spreads, collars, and straddles must be worked out one leg at a time and summed. For covered calls, run the covered call leg through the calculator separately and add the result to the covering leg's result.

Once you understand single-leg profit, the next step is combining legs. The Cboe Options Institute strategy pages (current edition) cover bull spreads (long call + short call at higher strike), bear spreads (long put + short put at lower strike), collars (three legs creating two plateaus), and straddles (long call + long put at same strike). Each multi-leg strategy's payoff is the sum of its leg payoff diagrams. Run each leg through this options calculator separately, then add the results.

The most common failure when building multi-leg positions is ignoring that short legs require margin under FINRA Rule 4210. For uncovered options, brokers demand cash deposits that can exceed the premium received. Always check margin requirements before entering a short position.
