In the Money (ITM): Definition, How It Works, and Why It Matters
How “In the Money” Works
“Moneyness” is the term traders use to describe the relationship between an option’s strike price and the current price of the underlying asset. It answers one question: does this option have intrinsic value right now?
An in-the-money option does. If you exercised an ITM call, you’d buy the stock below market price. If you exercised an ITM put, you’d sell the stock above market price. Either way, there’s immediate economic value — that’s intrinsic value.
Being in the money does not automatically mean you’re profitable on the trade. You still need to account for the premium you paid. An option can be in the money but still represent a net loss if the intrinsic value is less than the premium.
ITM for Calls vs. Puts
| Option Type | In the Money When | Intrinsic Value Formula | Example (Strike = $100) |
|---|---|---|---|
| Call Option | Stock Price > Strike Price | Stock Price − Strike Price | Stock at $112 → ITM by $12 |
| Put Option | Stock Price < Strike Price | Strike Price − Stock Price | Stock at $88 → ITM by $12 |
The Three States of Moneyness
Every option at any given moment falls into one of three categories:
| Status | Call Option | Put Option | Intrinsic Value |
|---|---|---|---|
| In the Money (ITM) | Stock > Strike | Stock < Strike | Positive |
| At the Money (ATM) | Stock ≈ Strike | Stock ≈ Strike | Approximately zero |
| Out of the Money (OTM) | Stock < Strike | Stock > Strike | Zero |
Moneyness is not static. An option can shift between ITM, ATM, and OTM multiple times during its life as the underlying stock price moves. A call that’s out of the money today can be deep in the money next week if the stock rallies.
Real-World Example
Amazon (AMZN) trades at $185. You bought a call option two weeks ago:
| Contract Detail | Value |
|---|---|
| Option Type | Call |
| Strike Price | $175 |
| Premium Paid | $7.00 per share ($700 total) |
| Current Stock Price | $185 |
Is it in the money? Yes — the stock ($185) is above the strike ($175). Intrinsic value = $185 − $175 = $10 per share.
Are you profitable? Yes — you paid $7.00 in premium and the intrinsic value alone is $10.00. Your profit is at least $3.00 per share ($300 per contract), plus any remaining time value.
What if the stock were at $180? Still in the money — intrinsic value = $5.00. But you paid $7.00 in premium, so you’d have a net loss of $2.00 per share if the option had no time value left. This is the important distinction: ITM doesn’t always mean profitable.
ITM vs. Profitable: The Breakeven Gap
This is where beginners get tripped up. “In the money” and “profitable” are not the same thing.
| Scenario | Stock Price | ITM? | Intrinsic Value | Premium Paid | Net P/L |
|---|---|---|---|---|---|
| Call: Strike $100 | $108 | Yes — by $8 | $8.00 | $5.00 | +$3.00 ✓ |
| Call: Strike $100 | $103 | Yes — by $3 | $3.00 | $5.00 | −$2.00 ✗ |
| Put: Strike $50 | $42 | Yes — by $8 | $8.00 | $4.00 | +$4.00 ✓ |
| Put: Strike $50 | $48 | Yes — by $2 | $2.00 | $4.00 | −$2.00 ✗ |
The breakeven is the point where intrinsic value equals the premium paid. For calls, breakeven = strike + premium. For puts, breakeven = strike − premium. You need the option to be in the money by more than the premium to actually profit at expiration.
Why ITM Options Cost More
In-the-money options are more expensive than ATM or OTM options because they already contain intrinsic value. You’re paying for a built-in advantage.
| Moneyness | Intrinsic Value | Time Value | Total Premium | Delta (approx.) |
|---|---|---|---|---|
| Deep ITM | High | Low | Expensive | 0.80–0.95 |
| Slightly ITM | Moderate | Moderate | Moderate-to-high | 0.55–0.70 |
| ATM | ~Zero | Highest | Moderate | ~0.50 |
| OTM | Zero | Low-to-moderate | Cheap | 0.05–0.40 |
The tradeoff: ITM options cost more but have a higher probability of expiring with value. OTM options are cheap but usually expire worthless. Delta serves as a rough proxy — an option with a delta of 0.70 has approximately a 70% chance of finishing in the money.
Characteristics of ITM Options
In-the-money options behave differently from ATM and OTM options in several important ways:
Higher delta. ITM options move more closely with the underlying stock. A deep ITM call with a delta of 0.90 gains roughly $0.90 for every $1 the stock rises. This makes deep ITM options popular as stock replacement strategies — similar directional exposure at a fraction of the capital.
Lower time value as a percentage of premium. Most of an ITM option’s price is intrinsic value, which doesn’t decay. The time value component is smaller, so theta decay has less impact in dollar terms. This makes ITM options more forgiving if the stock moves slowly.
Lower sensitivity to volatility. Because intrinsic value is a larger portion of the premium, changes in implied volatility (vega) have a proportionally smaller impact on ITM options compared to ATM options. An IV crush after earnings hurts an ATM option much more than a deep ITM option.
Higher probability of exercise. ITM options are more likely to be exercised at expiration. If you’re short (sold) an ITM option, expect assignment — especially as expiration approaches.
What Happens to ITM Options at Expiration
The Options Clearing Corporation (OCC) automatically exercises any option that is in the money by $0.01 or more at expiration. This is called “exercise by exception.”
| If You Hold… | What Happens | Watch Out For |
|---|---|---|
| Long ITM call | You buy 100 shares at the strike price | Make sure you have enough buying power in your account |
| Long ITM put | You sell 100 shares at the strike price | If you don’t own shares, you’ll be short 100 shares |
| Short ITM call | You’re assigned — must sell 100 shares at the strike price | If you don’t own shares, you’ll be short — unlimited risk until covered |
| Short ITM put | You’re assigned — must buy 100 shares at the strike price | You’ll own shares at the strike price, which may be above market value |
ITM in Common Strategies
| Strategy | How ITM Applies |
|---|---|
| Stock replacement | Buy a deep ITM call (delta ~0.85+) instead of buying shares — similar exposure, less capital |
| Covered call | Selling an ITM call generates more premium but increases the probability your shares get called away |
| Protective put | An ITM put provides immediate downside protection with no gap between stock price and strike |
| Vertical spreads | ITM legs of a spread carry intrinsic value and have higher delta, which defines the spread’s directional bias |
| Closing before expiration | Most traders sell ITM options before expiry to capture remaining time value instead of exercising |
Deep In the Money vs. Slightly In the Money
| Characteristic | Deep ITM | Slightly ITM |
|---|---|---|
| Delta | 0.80–0.95 (moves almost 1:1 with stock) | 0.55–0.70 |
| Time Value % | Very small (mostly intrinsic value) | Moderate |
| Theta Impact | Minimal (little time value to decay) | Noticeable |
| Cost | High (large intrinsic value component) | Moderate |
| Best For | Stock replacement, conservative directional trades | Moderate directional conviction with some leverage |
Key Takeaways
- An option is in the money when it has intrinsic value — for calls, stock price is above the strike; for puts, stock price is below the strike.
- Being in the money does not guarantee a profit — you must also account for the premium paid.
- ITM options cost more than ATM or OTM options because they already contain intrinsic value.
- ITM options have higher delta, less time value exposure, and a higher probability of finishing with value at expiration.
- The OCC automatically exercises options that are ITM by $0.01 or more at expiration.
- In most cases, selling an ITM option is better than exercising because selling captures both intrinsic and time value.
Frequently Asked Questions
What does “in the money” mean in simple terms?
An option is in the money when exercising it right now would have immediate value. For a call, the stock is trading above the strike price, so you could buy cheap. For a put, the stock is below the strike, so you could sell at a premium to the market.
Does in the money mean I’m making money?
Not necessarily. Being ITM means the option has intrinsic value, but you may have paid more in premium than the current intrinsic value. You’re only profitable when the option’s total value exceeds what you paid. The breakeven point is strike + premium for calls, and strike − premium for puts.
What happens if my option is in the money at expiration?
It gets automatically exercised by the OCC. A long ITM call means you’ll buy 100 shares at the strike price; a long ITM put means you’ll sell 100 shares at the strike. Make sure your account has enough funds, or close the position before expiration to avoid unwanted share transactions.
Should I buy in-the-money options or out-of-the-money options?
It depends on your strategy. ITM options cost more but have a higher probability of retaining value and move more closely with the stock (higher delta). OTM options are cheaper but need the stock to make a larger move to become profitable. ITM is more conservative; OTM is more speculative.
Can an option go from in the money to out of the money?
Yes — moneyness changes constantly as the stock price moves. A call that’s ITM today can become OTM tomorrow if the stock drops below the strike. This is why timing and expiration selection matter. Your option needs to be ITM at expiration (or when you sell it) for the intrinsic value to matter.
Why do deep ITM options have less time value?
Because there’s less uncertainty about their outcome. A call with a $80 strike when the stock is at $120 is almost certainly going to finish in the money — there’s little “optionality” left. The market doesn’t pay much for certainty. Time value is highest for ATM options where the outcome is most uncertain.
