How to use the Options Profit Calculator

Compute the expiration profit and break-even price for a purchased call or put option.

Calculation formula

Expiration payoff per share = max(spot − strike, 0) for calls or max(strike − spot, 0) for puts; net P&L = (payoff − premium) × 100 × contracts − fees.
