Intrinsic vs Extrinsic Value

Breaking Down an Option's Price

An option's premium can be decomposed into two components: intrinsic value and extrinsic value (also called time value). Understanding this breakdown helps you evaluate whether an option is cheap or expensive and is the foundation for every pricing decision in the wheel strategy.

Intrinsic Value

Intrinsic value is the amount by which an option is in-the-money. It represents the real, tangible value if the option were exercised right now. Out-of-the-money and at-the-money options have zero intrinsic value.

Call Intrinsic Value
Intrinsic = max(Stock Price - Strike Price, 0)
Put Intrinsic Value
Intrinsic = max(Strike Price - Stock Price, 0)
Intrinsic Value Calculation
Stock trades at $108. A $100 call has intrinsic value of $108 - $100 = $8.00. A $110 call has intrinsic value of $0 (it is out-of-the-money). A $110 put has intrinsic value of $110 - $108 = $2.00.

Extrinsic Value (Time Value)

Extrinsic value is everything in the premium above intrinsic value. It reflects the possibility that the option could gain more intrinsic value before expiration. Extrinsic value is driven primarily by time remaining and implied volatility. As expiration approaches, extrinsic value decays to zero -- this is the time decay that wheel sellers profit from.

Extrinsic Value
Extrinsic = Option Premium - Intrinsic Value
Full Premium Breakdown
Stock at $108. A $100 call trades for $11.50. Intrinsic value = $8.00. Extrinsic value = $11.50 - $8.00 = $3.50. The $3.50 is pure time value that will erode to $0 by expiration.
Why Wheel Traders Sell OTM Options
OTM options have zero intrinsic value -- their entire premium is extrinsic. Since extrinsic value decays to zero by expiration, selling OTM options means 100% of the premium you collect is subject to time decay working in your favor.
Key Takeaways
  • Intrinsic value = how far in-the-money an option is. OTM options have zero intrinsic value.
  • Extrinsic value = the portion of premium driven by time and volatility. It always decays to zero at expiration.
  • Option Premium = Intrinsic Value + Extrinsic Value.
  • Wheel traders sell OTM options so that the entire premium collected is extrinsic value that decays in their favor.
