How does this options profit calculator work?

This calculator supports long call and long put positions at expiration. For long calls, profit is the maximum of (underlying price - strike price) * 100 * contracts minus total premium paid. For long puts, profit is maximum of (strike price - underlying price) * 100 * contracts minus total premium paid. Break-even is strike + premium for calls, and strike - premium for puts. Maximum loss is always limited to the total premium paid.

What contract multiplier does this calculator use?

This calculator uses the standard US equity option contract multiplier of 100 shares per contract. Total profit/loss is multiplied by the number of contracts entered.
