This is an expiry-style long-option payoff check. It does not model time value, implied volatility, exercise, assignment, fees, spreads, liquidity, or venue settlement. Bounded max loss does not mean low risk.

Methodology and assumptionsformulas, limits, and FAQ

How this works

The payoff calculator models simple long call and long put positions. It is designed to teach premium, strike, breakeven, intrinsic value, and max loss before a trader thinks about strategy.

Long call breakeven

Strike price plus premium.

Long put breakeven

Strike price minus premium, floored at zero.

Max loss

Premium multiplied by contracts and contract multiplier for long options.

Assumptions

  • The calculator models long options only.
  • Contract multiplier is user supplied because venues can define contract sizes differently.
  • The current PnL estimate uses intrinsic value at the entered underlying price.

Do not ignore

  • It does not model implied volatility, time decay, exercise style, assignment, fees, spreads, or venue settlement.
  • Bounded max loss for a buyer does not mean the trade is low risk.
  • Options can lose money even if the trader is directionally right but paid too much premium.

Questions

Why is max profit unlimited for a long call?

A long call's payoff can keep increasing as the underlying price rises. In practice, liquidity, expiry, spreads, and settlement still matter.

Why is long put max profit capped?

The underlying price cannot fall below zero, so the maximum intrinsic value of a put is limited by the strike.

Does this calculate Greeks?

No. This calculator explains payoff shape. Greeks require volatility, time, rate, and pricing-model assumptions.

Separate payoff shape from Greeks, implied volatility, and expiry risk.

Breakeven

Translate premium and strike into the simple price hurdle.

Outcomes vs options

Compare binary payoff with call and put payoff before mixing terms.

Risk notice
Options are high-risk derivatives. Buyers can lose the full premium, pricing may move with volatility and time decay, and payoff estimates can fail when fees, spreads, liquidity, or settlement rules differ from the model.
