Reading the result

Expiration payoff only

The graph recalculates from the visible legs. It is not a price forecast and does not model outcomes before expiration.

Model boundary

This calculator uses intrinsic value at expiration and entered premiums. It excludes implied volatility, Greeks, time decay before expiration, fees, tax, dividends, liquidity, margin, assignment and exercise behavior. Educational illustration only—not financial advice.
