OptionLab is a set of free, browser-based options P&L calculators built to make the mechanics of options strategies visible before you risk real capital. Every calculation — breakeven, max profit, max loss, probability of profit, and the full Greeks — runs client-side using a Black-Scholes pricing engine, so your inputs never leave your browser.
Most options education either stays too abstract (formulas with no numbers attached) or too vague (rules of thumb with no way to check them against your own trade). OptionLab exists to close that gap: plug in a real strike, premium, and expiration, and see exactly how the position behaves across a full range of outcomes, instantly.
Six free calculators cover the strategies most retail options traders reach for first:
For traders who want more than a single calculation, OptionLab Pro is a paid dashboard that scans the S&P 500 and NASDAQ 100 daily with a multi-factor engine to surface probability-weighted trade ideas and options flow data.
OptionLab is an independently run project, not a broker-dealer, registered investment advisor, or licensed financial institution. The calculators and signals are educational tools, not personalized investment advice.
Not financial advice. Options trading involves substantial risk and isn't suitable for every investor. Always verify figures independently and consult a licensed advisor before making investment decisions. See our full Risk Disclosure.
