What is an Options Profit Calculator?
An options profit calculator helps traders visualize the potential profit and loss of an options position before entering a trade. By inputting the underlying stock price, strike price, premium, and expiration date, you can see a payoff diagram showing your P&L at every possible price at expiration.
How to Use This Calculator
- Search for a ticker — Enter any US stock symbol (e.g., AAPL, TSLA, SPY) to load the options chain.
- Select your position — Choose buy/sell, call/put, expiration date, and strike price.
- Analyze the results — View your payoff diagram, Greeks, break-even price, and max profit/loss instantly.
Understanding the Greeks
The Greeks measure different dimensions of risk in an options position. Delta tells you how much the option price moves per $1 change in the underlying. Gamma measures the rate of change of delta. Theta represents time decay — how much value the option loses each day. Vega shows sensitivity to changes in implied volatility.
