How to use
- 1Choose call or put, and whether you're buying (long) or selling (short).
- 2Enter the strike, the premium per share, the number of contracts and a price at expiration.
How it's calculated
Long call P/L = (max(0, S − K) − premium) × 100 × contracts. Long put P/L = (max(0, K − S) − premium) × 100 × contracts. Short positions are the negative. Values are at expiration only.
Frequently asked questions
What's the break-even for a call?
Strike plus premium. A $100 call bought for $5 breaks even at $105 at expiration.
What's the risk of selling options?
Selling a naked call has unlimited risk if the stock soars. Selling a put risks the strike minus premium per share if the stock goes to zero.
Does this show value before expiration?
No — before expiry, options also have time value that depends on volatility (e.g. Black-Scholes). This shows the payoff at expiration.
