What Is an In-the-Money (ITM) Option?

By OptionsPriceCalculator Team · Published October 20, 2026 · Updated October 20, 2026

An option is in-the-money (ITM) when exercising it right now would actually be worth something. For a call, that means the strike price sits below the stock’s current price. For a put, it’s the reverse - the strike sits above the current price. Either way, “in the money” is just a snapshot of where the strike and the stock happen to be at this instant; it says nothing about where the stock goes next.

The Two-Second Test

  • ITM call: stock price > strike price
  • ITM put: stock price < strike price

If you’d make money exercising the option this second, ignoring what you originally paid for it, it’s ITM. That “ignoring what you paid” part trips people up - an option can be deep ITM and still be a losing trade overall if you overpaid for it early on.

Why Being ITM Changes How an Option Behaves

An ITM option isn’t just closer to a payout - it behaves differently from an out-of-the-money one in three concrete ways:

  1. It costs more. The premium already includes real, exercisable value, not just a bet on the future.
  2. It moves more like the stock. A deep ITM option has a delta approaching 1.0 (calls) or -1.0 (puts), so it gains or loses almost dollar-for-dollar with the shares.
  3. It carries assignment risk if you’re the seller. The deeper ITM a short option gets, the more likely the holder on the other side exercises it - see assignment.

A Quick Example

Say AAPL trades at $340. A $330 call is ITM by $10 - exercising it right now would let you buy shares $10 below market, so it has $10 of intrinsic value built into its price. A $350 call on the same stock is out-of-the-money; it has zero intrinsic value, and every dollar of its premium is pure time value.

Flip it for puts: a $350 put on that same $340 stock is ITM by $10, because the put lets you sell shares $10 above where they’re trading. A $330 put is OTM.

ITM Isn’t a Prediction

A common beginner mistake is treating “ITM” as a bullish or bearish signal. It isn’t. It’s purely a description of today’s strike-vs-stock relationship, fixed the moment you check it. A call that’s $5 ITM this morning can be $5 OTM by the close if the stock drops $10. Moneyness - the broader concept ITM, ATM, and OTM all belong to - moves every time the stock does.
