Options profit calculator
Pick a strategy, enter strike, premium and contracts, and get the at-expiration payoff chart, breakevens and max gain/loss instantly. Everything is plain arithmetic on your inputs, computed in your browser — no model, no forecast. Arrive from any option-chain row link and the contract prefills from its delayed quote.
What each strategy computes
- Long call: profits when the stock closes above the strike at expiration; breakeven = strike + premium; max loss = premium paid, max gain unlimited.
- Long put: profits when the stock closes below the strike; breakeven = strike − premium; max loss = premium paid, max gain caps as the stock approaches $0.
- Covered call: 100 shares plus one short call; breakeven = stock cost − premium; upside is capped at the strike, downside matches the shares (less the premium).
- Cash-secured put: a short put backed by strike × 100 in cash; breakeven = strike − premium; max gain = the premium, and assignment means buying the shares at the strike.
- Protective put: 100 shares plus one long put; downside is floored at (strike − stock cost − premium) while the upside stays unlimited (less the premium).
This tool computes outcomes at expiration only (v1). Pre-expiration P/L depends on implied volatility and time value — that takes model assumptions; see the option value calculator.
