Before commissions and fees. This is one purchased, unadjusted 100-share stock/ETF call. Not puts, spreads, short options or adjusted contracts. Cent-priced inputs only.
Exercise buys 100 shares and needs additional funds. The premium-loss limit does not cap losses on shares you acquire. These calls do not automatically pay out cash; broker instructions and deadlines matter.
Winning isn’t the same as covering.
Finishing above the strike gives a call intrinsic value. It does not necessarily earn back the premium. Like winning without covering a spread, direction alone is not enough—but an option’s payoff changes with the stock price, unlike fixed sports odds.
The math
Contract cost = option price per share × 100.
Break-even at expiration = strike + option price per share.
Intrinsic value = max(finishing stock price − strike, 0) × 100.
Net expiration result = intrinsic value − contract cost.
Before expiration, an option’s sale price also depends on time, volatility and the available market. This calculator does not estimate it. Touching the break-even price earlier does not establish the expiration outcome.
