About this calculator
How to use the Call Broken Wing Butterfly calculator
Buy one lower-strike call, sell two middle-strike calls and buy one higher-strike call. Use the same expiration. Here, the upper wing is wider than the lower wing.
Understanding the payoff
Results add the payoff of each displayed leg, including quantities, entry prices and fees.
These formulas describe the standard strategy before fees. The results above include the total fees entered and are calculated from your actual legs.
Worked example
With XYZ at $100, buy the $95 call for $7, sell two $100 calls for $5 each and buy the $110 call for $2. The opening credit is $1 per share, or $100. At $100, the $95 call is worth $500 and the other options expire worthless, leaving $600 profit. At $110, the options lose $500 in total; the opening credit reduces the net loss to $400.
This is an expiration payoff estimate, not a live option quote or a prediction. It assumes all option legs expire together on one stock or ETF, the stock price cannot be negative, and options settle at intrinsic value. The default multiplier is 100 shares per contract; adjust it for the contract being modeled. Early assignment, exercise decisions, dividends, interest, taxes, and slippage can change realized results. Cash requirements and broker margin are separate from maximum loss. Different expirations, futures options, and adjusted contracts with non-cash deliverables are not supported.
Method: add each leg’s intrinsic value at expiration, subtract its entry cost with the correct buy/sell sign, and subtract total fees. See Cboe’s worked spread example on Fidelity for a reference calculation.
