How is a Long Put breakeven calculated?

At expiration, the standard Long Put breakeven is the strike price minus the premium paid per share. The calculator reflects the selected contract count in the position result.

What is the maximum loss on a Long Put?

For a purchased put held to expiration, the theoretical maximum loss is generally the premium paid, plus any applicable fees.
