An in-the-money (ITM) option is a contract whose strike price would let the holder buy or sell the underlying asset on better terms than the current market price. A call is in the money when the underlying trades above the strike. A put is in the money when the underlying trades below the strike. The amount by which an option is in the money is its intrinsic value. Being in the money does not by itself mean the position is profitable.

Moneyness: ITM, ATM and OTM

Moneyness describes where the underlying price sits relative to the strike. It uses three categories:

• In the money (ITM): exercising now would be favorable, because the strike beats the market price.
• At the money (ATM): the strike equals or is very close to the current price, so immediate exercise gains nothing. This is sometimes called “on the money.”
• Out of the money (OTM): the strike is unfavorable. Exercising would mean buying above market or selling below it, so a rational holder would not exercise.

If a stock trades at $50, a $45 call and a $55 put are both in the money. A $55 call and a $45 put are out of the money, and the $50 strikes are at the money. The strike stays fixed for the life of the contract. The underlying price is the part that moves, so a contract’s moneyness can change many times before it expires.

How intrinsic value is calculated

Intrinsic value per share is:

• Call: max(0, underlying price − strike price)
• Put: max(0, strike price − underlying price)

An option is in the money whenever this result is above zero. For standard US equity options, one contract covers 100 shares, so the per-share figure is multiplied by 100 to get the contract value. Other markets use different contract sizes, so check the multiplier before converting.

Hypothetical example: a call with a $200 strike on a stock trading at $223 has intrinsic value of $23 per share, or $2,300 per 100-share contract.

Premium: intrinsic plus extrinsic value

An option’s premium has two parts:

Premium = intrinsic value + extrinsic (time) value

Extrinsic value is what buyers pay for the chance that the option gains more value before expiration. It depends mainly on time remaining and implied volatility. More time or higher volatility gives the underlying more room to move favorably, which raises extrinsic value. Interest rates and dividends also have an effect. Pricing models such as the Black-Scholes model combine these inputs.

OTM and ATM options consist entirely of extrinsic value. ITM options carry both, which is why they cost more than other strikes in the same expiration. The deeper an option is in the money, the more of its premium is intrinsic value and the smaller the share that time decay can erode. Extrinsic value shrinks toward zero as expiration approaches. At expiration, an option is worth only its intrinsic value.

In-the-money call options

A call gives the holder the right, but not the obligation, to buy the underlying at the strike price. Call buyers are generally bullish: they expect the price to rise above the strike by expiration.

A call is in the money when the market price exceeds the strike. Its premium is at least its intrinsic value, which sets the floor, plus whatever extrinsic value the market assigns.

Hypothetical ITM call example

A trader holds a call with a $30 strike, bought for a premium of $3.50 per share ($350 per contract). The stock now trades at $33.

• Intrinsic value: $33 − $30 = $3 per share, or $300 per contract.
• Result if exercised and the shares are sold immediately: $300 − $350 = a $50 loss, before commissions.

The call is in the money, but the position is losing. For a long call, the break-even at expiration is strike + premium paid, here $33.50, plus any trading costs. If the stock then fell to $29, the call would be $1 out of the money with no intrinsic value left.

In-the-money put options

A put option gives the holder the right to sell the underlying at the strike price. Put buyers are generally bearish, or they hold puts to protect shares they own.

A put is in the money when the strike is above the market price, so the holder can sell for more than the asset is currently worth.

Hypothetical ITM put example

A trader owns a put with a $249 strike, bought for $2.80 per share ($280 per contract). The stock trades at $247.

• Intrinsic value: $249 − $247 = $2 per share, or $200 per contract.
• Result if exercised now: $200 − $280 = an $80 loss, before costs.

The break-even at expiration for a long put is strike − premium paid: $249 − $2.80 = $246.20. Below that price, every additional dollar of decline adds $100 per contract to the gain, until the stock reaches zero.

ITM European-style call options

Exercise style determines when the holder can act on an ITM position:

• American-style options can be exercised on any business day up to expiration.
• European-style options can be exercised only at expiration.

An ITM European-style call that is in the money a month before expiration cannot be exercised that day. Its holder has two choices: sell the contract in the market, or wait and hope it is still in the money at expiry. Whether it ends ITM depends only on the underlying price at expiration. A call that is deep in the money two weeks out can still expire worthless if the price drops below the strike.

The market price of an ITM European call can also trade slightly below its intrinsic value. This happens most often when the underlying pays dividends, because the holder cannot exercise early to capture the dividend. Many index options are European-style and cash-settled. At expiration, the holder receives the intrinsic value in cash rather than shares.

For American-style options, early exercise is possible but usually gives up the remaining extrinsic value. Selling the contract normally captures more. The main exceptions involve deep ITM calls just before a dividend and deep ITM puts.

What happens at expiration

At expiration, extrinsic value is gone, and an ITM option’s value equals its intrinsic value. For US-listed equity options, contracts that are in the money by $0.01 or more are generally exercised automatically unless the holder instructs the broker otherwise. A long ITM call can therefore turn into a share purchase that requires the full cash amount for 100 shares per contract. A long ITM put can turn into a short stock position if the holder does not own the shares.

Option sellers face the opposite side. A writer of an ITM option should expect assignment at expiration. With American-style options, assignment can also come earlier.

How traders use ITM options

• Stock substitution: a deep ITM call behaves much like the shares themselves. Its delta, the sensitivity of the option price to a $1 move in the underlying, approaches 1, as the option Greeks show. The call costs far less than 100 shares, but it can expire and it still loses value over time.
• Hedging: ITM puts give protection that starts working immediately, at a higher cost than OTM puts.
• Income strategies: some covered-call writers sell ITM calls to collect a larger premium, accepting that the shares will likely be called away.

Limitations and common confusions

ITM is not the same as profitable. Profit depends on the premium paid and trading costs, not on moneyness alone. When a brokerage app shows “ITM” next to an option, it is describing the strike against the current price, not the position’s profit and loss.

Higher cost means more capital at risk. An ITM option ties up more money per contract than OTM strikes. If the underlying moves sharply the wrong way, the intrinsic value can disappear and take a large part of the premium with it.

Leverage is lower. For a given dollar move in the underlying, ITM options produce a smaller percentage return than cheaper OTM contracts. They also lose a smaller percentage, because their price is made up mostly of intrinsic value.

Liquidity can be thinner. Deep ITM strikes often trade less than strikes near the money, which can mean wider bid-ask spreads. Checking open interest and the quoted spread before trading helps avoid paying away much of the intrinsic value.

The Bottom Line

Option buyers and sellers who rely on brokerage labels need to know that ITM describes the strike against the current price, not profit. A position can be in the money and still lose after premium and costs. Traders using ITM contracts should check break-even, exercise style, automatic exercise rules and bid-ask spreads before committing the larger capital these options require.
