How to calculate options profit
- Choose call or put. Pick the option type you bought.
- Enter strike, premium and contracts. Type the strike price, the premium per share you paid, and how many contracts.
- Set the expiration price. Enter a stock price at expiration to see profit, return and the payoff table.
Reading an options payoff
A long option's profit at expiration depends only on where the stock lands versus your strike, minus what you paid. A call gains as the stock rises past the strike; a put gains as it falls. Your loss is capped at the premium, which is why defined-risk option buying appeals to many traders — but most options expire worthless, so timing and the price paid matter. To value a position before expiration (including time value), use the Black-Scholes calculator, and gauge how far the stock might move with the expected-move calculator.
Educational tool only — not financial advice. Options trading carries a high level of risk, including the loss of your entire premium, and is not suitable for every investor.
Frequently asked questions
- At expiration, a call is worth max(stock price − strike, 0) and a put is worth max(strike − stock price, 0), per share. Profit = (that value − the premium you paid) × contracts × 100. This calculator does it for you and also shows your breakeven and return.
- For a long call it is the strike plus the premium; for a long put it is the strike minus the premium. Above (call) or below (put) that price, the trade is profitable at expiration.
- For a bought (long) call or put, the maximum loss is the premium you paid — nothing more. The maximum profit is unlimited for a call and (strike − premium) × 100 per contract for a put.
- No — it shows profit and loss at expiration only. Before expiry an option also carries time value; use the Black-Scholes and implied-volatility calculators for the value of an open position.
- No. The calculation runs entirely in your browser. Nothing is uploaded or stored.
