Intrinsic value is one part of the option premium
For the fictional American-style equity options in this guide, a call’s intrinsic value is max(underlying price − strike price, 0); a put’s is max(strike price − underlying price, 0). Time value, also called extrinsic value, is the premium minus that intrinsic value.
If a call has an underlying price of 120, a strike of 100 and a premium of 25 per underlying unit, its intrinsic value is 20 and its remaining time value is 5. The 20 is not net profit after paying the premium.
Keep the underlying price, strike and premium separate
The underlying price is the price of the stock. The strike is the price specified in the option contract. The premium is the option’s own price. Confusing these three amounts makes it easy to mistake an in-the-money option for a profitable purchase.
The Options Industry Council, or OIC, describes a premium as having intrinsic and time-value components. It also explains the different call and put relationships: a call is in the money when the underlying price is above its strike; a put is in the money when the underlying price is below its strike.[1]
Our examples are separate fictional snapshots of American-style equity options before expiration. Underlying price S, strike K and premium P are all stated in the same fictional currency per underlying unit. We assume no contract multiplier, and do not convert any row into a whole-contract payment.
American-style describes an option that can be exercised before expiration as well as at expiration.[2] This is a description of the chosen contract style, not an instruction to exercise. Other styles and contract terms need their own analysis.
Calculate intrinsic value, then subtract it from the premium
For the chosen examples, let I mean intrinsic value and T mean time value. T is an amount of premium, not the number of days remaining. Use these steps:
- Call: I = max(S − K, 0).
- Put: I = max(K − S, 0).
- Remaining component: T = P − I.
The zero in the intrinsic-value formula prevents an out-of-the-money option from being assigned a negative intrinsic amount. It does not remove the premium paid or establish that the whole trade is profitable.
| Option | Underlying S | Strike K | Premium P | Intrinsic I | Time value P − I |
|---|---|---|---|---|---|
| In-the-money call | 120 | 100 | 25 | max(120 − 100, 0) = 20 | 25 − 20 = 5 |
| In-the-money put | 80 | 100 | 25 | max(100 − 80, 0) = 20 | 25 − 20 = 5 |
| Out-of-the-money call | 90 | 100 | 3 | max(90 − 100, 0) = 0 | 3 − 0 = 3 |
The call and put in the first two rows have the same split, although the underlying price is on a different side of the strike. In the third row, zero intrinsic value does not mean zero premium: all 3 units of the stipulated premium are time value.
The option’s stipulated price per underlying unit.
For the call, 120 − 100. For the put, 100 − 80.
Premium 25 − intrinsic 20.
Intrinsic value is not profit after the premium
“In the money” describes the relationship between the underlying price and the strike. It does not account for what you paid for the option.
If you had paid 25 per underlying unit for either of the first two options, subtracting that premium from the intrinsic amount of 20 gives −5 before costs, not a profit of 20. This arithmetic comparison is not a completed transaction or a statement of current realized profit.
Likewise, the remaining 5 is a component of the option price. It is not an extra cash payment you receive, a guaranteed future return or a probability-weighted expected payoff. To calculate an actual net result, you would need the transaction and contract details, prices and applicable costs. The risk–reward guide explains why units and costs belong in a profit calculation.
Time value depends on more than the clock
The name can be misleading: time value is not a fee calculated from time remaining alone. OIC lists underlying price, strike, time until expiry, implied volatility, dividends and interest rates among the inputs that influence an option’s premium.[1] Changes in those inputs can change the premium and its remaining component.
As expiration approaches, time value generally erodes with other relevant inputs held fixed. That relationship does not guarantee that an actual option’s quoted price falls at every observation. Changes in the underlying price or implied volatility, for example, can occur while time passes.
The three rows above are independent snapshots, not a price path through time. They do not estimate a decay rate, a fair premium or tomorrow’s price. The formulas separate a stipulated premium into components; they are not a complete option-pricing model.
Read the unit and contract terms before using the result
All amounts in the example use one common per-underlying-unit convention. A whole-contract amount would require the actual contract’s multiplier or deliverable. Do not silently multiply every option by 100 or assume that every contract has identical settlement terms.
The numerical time values here are positive because of the chosen inputs. This guide does not turn those examples into a universal claim about premium-minus-intrinsic across every option style or product.
A price component also answers a different question from expected value. There is no probability distribution in this example, so the remaining premium is not a calculated chance of success or an expected profit. See the distinction between an average outcome and a probability before applying either label.
Frequently asked questions
What is the difference between intrinsic value and time value?
Intrinsic value uses the underlying price and strike under the chosen call or put formula. Time value is what remains when you subtract that amount from the premium. In the fictional 25-unit examples, the split is 20 intrinsic plus 5 time value.
Can an option have a premium but no intrinsic value?
Yes. The fictional call with S = 90, K = 100 and P = 3 has intrinsic value max(90 − 100, 0) = 0 before expiry. Its remaining time value is 3 − 0 = 3 per underlying unit.
Does an intrinsic value of 20 mean a profit of 20?
No. It does not subtract the premium paid or costs. If you had paid 25 per underlying unit, intrinsic value of 20 minus that premium would be −5 before costs. That comparison alone is not a record of a realized transaction.
Does time value always decrease as each day passes?
Time passing generally erodes time value when other relevant inputs are held fixed. Actual premiums can also respond to the underlying price, implied volatility and other inputs, so a quoted price need not decline at every observation. Our examples contain no price path or forecast.
Should I multiply these numbers by 100?
No multiplier has been assumed in the table. The figures are prices per underlying unit. A whole-contract calculation needs the actual multiplier and contract terms; these examples do not establish them or provide exercise instructions.
