How this calculator works

A long call gives the holder the right to buy shares at the strike through expiration and typically gains value as the underlying rises.

How to use it

Use the strike and premium from the contract you are considering, then compare the target price with the expiration break-even. If you expect to exit early, include a realistic date and implied-volatility assumption because time value remains part of the option price.

Formula, payoff, and assumptions

At expiration, call value is the greater of stock price minus strike or zero; profit subtracts the premium paid.

The expiration payoff assumes the option is held to expiry. A planned sale before then depends on remaining time value and implied volatility, which are modeled rather than known in advance.

Practical example

A $100 strike call bought for $4 breaks even near $104 at expiration before fees.

Reading this result

Compare the target price with the break-even and the time remaining, not with the strike alone. A move above the strike can still leave the position below its full-cost break-even.

Common planning mistake

A common error is assuming a call must be held to expiration. A planned early exit has time value, volatility, and bid-ask spread exposure that the expiration payoff does not show.

Risk and limitations

The entire premium can be lost. Before expiration, results also depend on implied volatility and remaining time.
