Every option’s price is made of two parts: intrinsic value, which is its real exercisable worth right now, and extrinsic value, which is the time-and-volatility premium on top. Knowing the split between them is key to timing entries and exits well.
Open the Covered Call calculator →Intrinsic value is what the option would be worth if exercised immediately: for a call it is the stock price minus the strike (never below zero); for a put it is the strike minus the stock price.
Only in-the-money options have intrinsic value. An out-of-the-money option’s entire price is extrinsic.
Extrinsic (time) value is everything above intrinsic — the premium you pay for the chance the option gains more before expiration. It is driven mainly by time remaining and implied volatility.
Extrinsic value decays to zero by expiration via theta. Premium sellers aim to harvest it, while buyers are racing against it.
A deep ITM option is mostly intrinsic value, so it behaves much like the stock with little decay; an ATM or OTM option is mostly extrinsic and far more exposed to time and volatility.
When you buy an option you are buying extrinsic value that will erode; when you sell one you are selling it. That single idea explains most of options pricing behaviour.
No. It can shrink to zero at expiration but never goes below zero; deep ITM options can briefly trade near pure intrinsic value.
Higher implied volatility means a wider range of possible outcomes, so the chance of the option gaining value increases — and the market charges more for it.
At-the-money options with plenty of time left carry the most extrinsic value and therefore decay the fastest near expiration.
