Option Breakeven
A free, no-account-required options P&L calculator built for retail traders who want to understand the full profit and loss profile of their options before placing a trade.
What it does
Option Breakeven lets you analyze any equity option — call or put — by calculating:
- 📊P&L Scenarios: A full heat-map table showing your profit or loss at every stock price and date combination until expiry.
- ⚖️Breakeven Price: Exactly where the stock needs to be at expiry for you to break even on your premium paid.
- 🧮Greeks: Delta, Gamma, Theta, and Vega — estimated using the Black-Scholes model — so you understand how time, volatility, and price movement affect your position.
- 🔗Shareable Links: Every analysis can be shared via a URL. Anyone with the link instantly sees the same P&L data — no login needed.
- 📈Live Options Chain: Real-time (15-min delayed) strike and premium data fetched directly from Yahoo Finance for any US-listed equity.
How it works
All option pricing and Greeks are calculated using the Black-Scholes-Merton model, the industry-standard mathematical model for European-style option pricing. Inputs are the current stock price, strike price, implied volatility, days to expiry, and a risk-free rate (US 10-year Treasury approximation).
When you enter a real ticker, live option chains are fetched from Yahoo Finance (delayed up to 15 minutes). Strike prices, bid/ask spreads, and implied volatilities from the live market replace the theoretical Black-Scholes approximations, giving you real-world pricing.
Who it's for
Option Breakeven is built for retail traders who are learning options or want a quick second-opinion on a trade. It is intentionally simple — no spreads optimizer, no portfolio tracker, no order routing. Just a fast, honest look at your P&L before you click "buy."
