Moneyness

Moneyness describes the relationship between the stock price and the strike. A call is in the money (ITM) when the stock is above the strike, at the money (ATM) when they are roughly equal, and out of the money (OTM) when the stock is below. For puts it is reversed. An ITM option has intrinsic value; an ATM or OTM option is all extrinsic.

Moneyness drives the other Greeks. ATM options carry the most extrinsic value, the biggest vega, and the steepest end-of-life theta. Deep ITM options behave almost like the stock; far OTM options behave like cheap lottery tickets with low delta.

Worked number. With the stock at $100 and a $105 strike, the default call is out of the money by about 5%. It has zero intrinsic value, so its entire $3.27 price is extrinsic, a bet the stock climbs past $105 before expiry.

FAQ

Is at-the-money the same as breakeven?

No. At the money means the stock is near the strike. Breakeven also accounts for the premium you paid, so it sits above the strike for a call by the premium amount.
