Intrinsic Value
The portion of an option’s premium that would be realized if exercised right now.
Also called: in the money value
Written by Javier Sánchez Ros
In plain language
For a call, intrinsic value is the current price minus the strike, floored at zero. For a put it is the strike minus the current price, also floored at zero.
Out-of-the-money options have zero intrinsic value. Their entire premium is extrinsic, which is another way of saying it can all disappear.
Intrinsic value moves essentially one-for-one with the underlying once an option is deep in the money.
The formula
Intrinsic Value
max(Price − Strike, 0) call · max(Strike − Price, 0) put
Worked through
Splitting a $6.40 premium into its two parts
- Stock
- $104.00
- Call strike
- $100.00
- Intrinsic value
- $4.00
- Extrinsic value
- $2.40
Four dollars of this premium is not an estimate of anything. The right to buy at $100 something trading at $104 is worth $4 today and would be worth $4 if expiry were this afternoon. That portion cannot decay, because it is arithmetic rather than expectation.
The remaining $2.40 is the market’s price for what might still happen before expiry, and it is the part with a deadline. Hold to expiration with the stock unchanged and that $2.40 is gone, leaving a contract worth exactly $4.
Making the split explicit answers a question that otherwise has no obvious answer: what am I actually paying for? A deep in-the-money option is mostly intrinsic, so it behaves much like the stock and decays slowly. A far out-of-the-money option is entirely extrinsic, so all of it is on a timer.
It also sets the floor. An in-the-money option cannot fall below its intrinsic value, which is a genuine structural difference from one that has none — the second can reach zero, and routinely does.
Why it matters
Intrinsic value is the part of the premium that is real and durable. Everything above it decays toward zero as expiration approaches.
Common mistakes
- Buying purely extrinsic value without recognizing it is a wasting asset.
- Assuming an in-the-money option cannot lose value. It can — the extrinsic portion still decays.
