How to calculate options profit

  1. Choose call or put. Pick the option type you bought.
  2. Enter strike, premium and contracts. Type the strike price, the premium per share you paid, and how many contracts.
  3. 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

How is options profit calculated?
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.
What is the breakeven price?
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.
What is the most I can lose?
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.
Does this account for early exercise or time value before expiry?
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.
Is my data sent anywhere?
