Option calculator
When you have a future stock scenario
Set a stock price, date, and IV to estimate strategy value and profit or loss
Compare modeled profit or loss across future stock prices, dates, and implied volatility for single and multi-leg strategies
How to read the estimate
A forward estimate, then a clearer Path
This calculator answers what an option might be worth under inputs you choose. Mark's core analysis reverses that question and shows what your target premium needs

Option calculator questions
Is the estimated premium a forecast?
No. It is a model estimate under the stock price, date, and IV assumption you selected
Does this show the chance of reaching the estimate?
No. The calculator does not present a probability or a touch-before-deadline estimate
Why can an option fall when the stock moves correctly?
Time, implied volatility, liquidity, and the size of the stock move can all change the option premium
Does this include my entry premium, quantity, or fees?
No. Results use illustrative entry values for one strategy unit and exclude fees, so use them to compare scenarios rather than reconcile a trade
