What you will learn
- Define in-the-money, at-the-money, and out-of-the-money
- Classify a call's moneyness from the price and strike
- Classify a put's moneyness from the price and strike
- Understand why moneyness governs an option's behavior
A key idea for understanding an option's value is moneyness, which describes the relationship between the option's strike and the current price of the underlying. Moneyness tells you whether an option would be worth exercising right now, and it shapes the option's price, its risk, and how it responds to movements in the underlying. The terminology applies to both calls and puts, but in opposite directions.
In-the-money, at-the-money, and out-of-the-money explained (Options Industry Council)
The definitive short explainer on moneyness from the OIC. Watch how it differs for calls and puts.
The three states
Every option is in one of three states. An option is in-the-money when exercising it would produce a positive payoff, at-the-money when the strike is roughly equal to the current price, and out-of-the-money when exercising it would not be profitable. Which state an option is in depends on whether it is a call or a put, because calls benefit from rising prices and puts from falling ones.
Key terms
- In-the-money (ITM)
- Exercising now would produce a positive payoff.
- At-the-money (ATM)
- The strike is roughly equal to the current underlying price.
- Out-of-the-money (OTM)
- Exercising now would not be profitable.
| State | Call | Put |
|---|---|---|
| In-the-money | S above K | S below K |
| At-the-money | S near K | S near K |
| Out-of-the-money | S below K | S above K |
Moneyness asks a simple question: if you exercised right now, would it pay off? In-the-money says yes, out-of-the-money says no.
Classify the option
A stock trades at 45 dollars. You hold a call with a strike of 50 dollars. What is its moneyness?
For a call, in-the-money means the price is above the strike. Here the stock at 45 is below the 50 strike, so the call is out-of-the-money: exercising the right to buy at 50 makes no sense when you could buy at 45 in the market.Match the situation to its moneyness

Why moneyness matters
Moneyness is not just a label, it governs how an option behaves. In-the-money options have real, immediate exercise value, which the next lesson calls intrinsic value, while out-of-the-money options have none and consist purely of the possibility of becoming valuable before expiration. Moneyness strongly influences the premium, the sensitivity to the underlying, and the risk and reward. A deep in-the-money option behaves much like the underlying itself, moving nearly dollar for dollar with it, while a deep out-of-the-money option is cheap and behaves like a long-shot lottery ticket, worth little but capable of large percentage gains if the price moves dramatically.
ITM versus OTM behavior
In your own words, explain why a deep in-the-money option moves almost like the stock itself while a deep out-of-the-money option behaves like a lottery ticket.

Model answer
A deep in-the-money option already has a lot of real exercise value, and since the strike is far from the current price, a one-dollar move in the stock changes the option's exercise value by almost a full dollar. So it tracks the underlying closely, behaving much like owning the stock. A deep out-of-the-money option has no exercise value at all and only pays off if the price makes a big move to cross the strike before expiration. That is unlikely, so the option is cheap, but if the move does happen its value can jump many times over. That mix of low cost and low probability with a large potential payoff is exactly why it behaves like a lottery ticket.
In-the-money options carry real exercise value, and out-of-the-money options carry only possibility. That distinction is the split between intrinsic value and time value, which the next lesson makes precise.
