This is an educational estimate, not a market quote. Before expiration it uses a Cox-Ross-Rubinstein binomial model for an American-style stock option, allowing exercise at each step. Brokers, exchanges, and OCC may use proprietary model variations, discrete dividends, intraday timing, and different market inputs. Actual tradable prices come from market bids and asks. Changing volatility, spreads, fees, taxes, liquidity, exercise, and assignment can make the real result different. The sell-call view is uncovered; use covered call to include your shares. Inputs stay in your browser. Learn about option-pricing models from the Options Industry Council.
