About the Calendar Call Spread

The calculator opens with a calendar call spread: the at-the-money call sold in the nearest expiration and the same-strike call bought in the next one.

The spread is a net debit position that profits from time decay: the near call loses value faster than the far one. It does best with the stock near the strike when the near call expires, and gains from a rise in implied volatility. Its value then depends on what the far call is still worth, which the chart models; the most it can lose is about the debit.

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 Calendar Call Spreads Screener: its chart icon opens this calculator with the selected position.
