Frequently Asked Questions
How is the break-even price of an option computed?
For a call it is the strike plus the premium; for a put it is the strike minus the premium. At expiry, the stock at exactly that price makes the position profit zero before fees.
Why does a short call show unlimited max loss?
A short call obligates you to sell shares at the strike no matter how high the stock climbs, so the theoretical loss has no ceiling. The calculator labels that side unlimited instead of inventing a cap.
Does the payoff include time value or fees?
No. The payoff assumes the position is held to expiry and uses intrinsic value only, excluding commissions, fees, and early-exercise considerations.
What does the contract quantity mean?
One standard option contract covers 100 shares. Entering 2 contracts means the payoff numbers apply to 200 shares of underlying stock.
