How to Use the 100x Options Calculator
The 100x Options Calculator helps you determine if your option trade has positive or negative expectancy. It looks at four inputs: max risk on the trade, the probability of hitting max risk, max profit on the trade, and the probability of hitting max profit.
Enter the percentage for hitting your max loss and max gain as numbers only (e.g. 30 for 30%), plus the max loss and max gain in dollars for a single trade. The calculator shows weighted outcomes after 100 trades and whether the setup favors you over time.
This will not work on strategies that do not have a fixed max risk or fixed max gain — such as naked short options or positions with undefined upside or downside.
- 1Enter max loss ($) — the most you can lose if the trade hits max risk.
- 2Enter max profit ($) — the most you can make if the trade hits max gain.
- 3Enter prob. ITM loss (%) — your estimate of hitting max loss.
- 4Enter prob. ITM profit (%) — your estimate of hitting max profit.
- 5Review expected outcome after 100 trades and the positive/negative verdict.
