Your option
At expiration
Today's value is a Black-Scholes estimate (European exercise, no dividends) from your days left, implied volatility and rate. Real quotes also carry the bid-ask spread.

How it works
At expiration an option is worth only its intrinsic value: a call is worth the stock price minus the strike (if positive), a put the strike minus the stock price. Your profit is that value minus the premium, times 100 shares per contract. The break-even is the strike plus the premium for a call and the strike minus the premium for a put.
Before expiration the option also carries time value, which this calculator estimates with the Black-Scholes model from the days left, the implied volatility and the interest rate. Black-Scholes assumes European exercise and no dividends, so treat the "today" column as an estimate — real quotes also include the bid-ask spread.
Buying an option caps your loss at the premium paid; selling one caps your profit at the premium received, and a short call's loss is unlimited. Size option trades by that maximum loss, the same way you'd size a stock trade by the distance to its stop.
Frequently asked
How do you calculate profit on a call option?
At expiration: (stock price − strike − premium) × 100 × contracts, with a minimum loss of the premium paid. A 105 call bought for $3.20 makes money above $108.20 at expiry.
What is the break-even on a put option?
Strike minus the premium paid. A 50 put bought for $2 breaks even at $48 at expiration; below that it profits.
What is the maximum loss when buying an option?
The premium you paid, times 100 shares per contract. When selling an option, the maximum loss is unlimited for a call and strike minus premium (times 100) for a put.
What does Black-Scholes assume?
European exercise (only at expiry), no dividends, a constant interest rate and constant volatility. It's the standard way to estimate an option's fair value, not a quote you can trade at.
