What the numbers mean
Every figure is at expiration. Before then an option carries time value and is worth more than the table shows. That gap is the single most common surprise for a new options trader, and on a weekly option it closes fast, because there are only days of time value to lose.
The premium is the ceiling on your loss when you buy. It is known before the trade, which is what makes a defined-risk position different from being short. Our call options page covers what moves the premium in the first place.
At the strike, a bought option is still a total loss. The stock has to clear the break-even price, not just the strike, which the table makes plain.
Common questions
How do you calculate profit on a call option?
Take the stock price at expiration minus the strike. If that is positive, multiply it by 100 for each contract to get what the position is worth. Subtract what you paid, which is the premium times 100 per contract. If the stock finishes at or below the strike, the call expires worthless and you lose the premium.
How do you calculate profit on a put option?
The same in reverse. Strike minus the stock price at expiration, if positive, times 100 for each contract, less the premium paid. Above the strike the put expires worthless.
What is the break-even price on an option?
For a call it is the strike plus the premium per share. For a put it is the strike minus the premium. At exactly that price the position returns nothing, it does not lose.
How much can I lose buying an option?
When you buy a call or a put, the premium you paid is the most you can lose. It is known before you place the trade. Selling options you do not own is a different activity with a different risk profile, and this calculator does not cover it.
Does this account for time value?
No, and that is deliberate. Every figure here is the value at expiration, when only intrinsic value is left. Before expiry an option is worth more than this, because time still has value. A calculator that guessed at that would be pricing the option, which needs volatility inputs nobody has to hand.
Why is one contract 100 shares?
Standard US equity options are written on 100 shares, so a premium quoted at 3.00 costs 300 dollars for one contract. Quotes are per share and the cost is per contract, which is where most arithmetic mistakes start.
