Free options profit calculator. See your payoff chart, breakevens, probability of profit and Greeks for any strategy — beginner-friendly, mobile-first, no signup.

Hey Product Hunt I built OptionProfitSim out of a simple frustration: most options calculators out there are either clunky, buried in ads, or lock the useful stuff behind a signup. I just wanted a fast, clean way to see the risk and reward on a trade before placing it — max profit, max loss, breakeven, probability of profit — without jumping through hoops. So I made the tool I wished existed. Pick any ticker and strategy (covered call, cash-secured put, iron condor, and more) and the payoff chart updates instantly. It's free, no account needed, and works on your phone. It's early and I'm actively improving it — I'd genuinely love feedback on the calculations and the UX. What would make this actually useful in your workflow? Thanks for taking a look

Does the probability of profit calculation factor in implied volatility skew, or is it more of a basic estimate based on the underlying's recent moves?

How are you estimating the probability of profit under the hood, is that based on historical IV or a Black-Scholes style model with a flat vol assumption?

Curious how you pull the probability of profit number, is it based on a standard pricing model like Black-Scholes or something custom? Also wondering if the data updates in real time or is just using end-of-day snapshots under the hood.
