Payoff at expiration. Gold dashed line = breakeven. The curve ignores commissions, and assumes you hold to expiration — a real trade also faces time decay and IV changes before then.

The number this calculator can't show you: whether the trade was worth taking. That's what a tracked record is for — we publish every model card with its trigger, target and stop before the move, wins and losses alike, and even published the backtest where our own raw scanner loses. The scoreboard is free to watch. Join the floor →

How the math works

For a long call, profit per share at expiration is max(price − strike, 0) − premium. Breakeven is strike + premium, and your maximum loss is the full premium (paid × 100 × contracts) if the stock finishes at or below the strike. A long put is the mirror: profit per share is max(strike − price, 0) − premium, breakeven is strike − premium, and again the most you can lose is the premium. See what a call option is and how premium works for the plain-English version.

Common questions

Does this include time decay before expiration?

No — this is the payoff at expiration, when time value is gone. Before expiry, an option's value also moves with theta and implied volatility, so the same stock price can produce a different P&L earlier in the trade.

Why is the most I can lose just the premium?

A bought option is a right, not an obligation. If it expires worthless you simply lose what you paid — no more. That capped downside is the appeal, but note it goes to zero routinely: most cheap, short-dated options expire worthless.

Is a bigger return always better?

No. A far out-of-the-money option shows a huge percentage return on the calculator because it's cheap and unlikely — the return is large precisely because the probability is small. Read the payoff alongside delta as a rough probability guide.
