Options Profit Calculator FAQ
Common questions about the calculation and how to interpret the estimate.
Why default to 100 shares?
A standard US listed equity option contract usually multiplies by 100.
Is premium per share or per contract?
Enter premium per share; total premium cost is premium × shares.
What if the option expires OTM?
Intrinsic value is zero and P/L equals −premium × shares.
Are commissions included?
No. Add them mentally or adjust premium slightly.
Can I model short options?
Not in this version—payoffs would reverse signs.
