About the Bull Put Spread

The calculator opens with a bull put spread in the nearest expiration: one at-the-money put sold and one put at the next lower strike bought.

The spread is a net credit position that profits when the stock holds up. At expiration it keeps the whole credit with the stock at or above the higher strike, and loses at most the distance between the strikes minus the credit, with the stock at or below the lower strike. The breakeven is the higher strike minus the credit.

Change the symbol, strikes, expirations or quantities, or add legs: the calculator takes up to eight option contracts and one stock position. To find candidates, use the Bull Put Spreads Screener: its chart icon opens this calculator with the selected position.
