How option profit at expiry is calculated

Call value at expiry = max(0, Price − Strike)
Put value at expiry  = max(0, Strike − Price)
Profit (long)        = (Value at expiry − Premium) × Shares per contract × Contracts

A short (written) option is the mirror image: you keep the premium and pay out the value at expiry.

Example

Buy 1 call with a $100 strike for $3.50. You pay $350 (3.50 × 100 shares). If the stock is $110 at expiry, the call is worth $10, so profit = (10 − 3.50) × 100 = $650. Break-even is $103.50. If the stock finishes below $100, you lose the $350 premium.

At expiry only. Before expiry an option’s price also depends on time left, volatility and interest rates, so it can be worth more than these figures. Commissions and early assignment aren’t included. US equity options usually cover 100 shares per contract; change it for other markets.

FAQ

How do you calculate profit on a call option?
At expiry: (stock price − strike − premium) × 100 × contracts, if the stock is above the strike. If it finishes at or below the strike, you lose the premium paid.
How do you calculate profit on a put option?
At expiry: (strike − stock price − premium) × 100 × contracts, if the stock is below the strike. Otherwise you lose the premium.
What is the break-even price of an option?
For a call it's the strike plus the premium; for a put it's the strike minus the premium.
Why is my option worth more than the calculator shows?
The calculator shows value at expiration. Before expiry, options also carry time value, which depends on time left and volatility.
How many shares is one options contract?
Standard US equity options cover 100 shares. Other markets and mini contracts can differ, so you can change it.
