- Time Value and Option Premium: The time value of an option is a component of the option premium that represents the amount of time remaining until expiration. The longer the time until the end, the higher the premium because there is a greater chance the option will become profitable (in the money).
- Time Decay: The time value decreases as the option approaches its expiration date. This is known as time decay or theta. The rate of time decay accelerates as the option gets closer to expiration, reducing the option’s premium.
- Intrinsic and Extrinsic Value: An option’s total price consists of intrinsic value (the difference between the underlying asset’s price and the strike price) and extrinsic value (time value and volatility value). When an option is out-of-the-money or at-the-money, its price essentially comprises time value.
- Impact of Interest Rates: Time value is also affected by risk-free interest rates. Higher interest rates increase the time value of call options and decrease the time value of put options. Lower interest rates have the opposite effect.
- Volatility Impact: Time value increases with volatility because a more volatile market means a greater chance of the option ending up in the money. Therefore, options on more volatile assets command a higher premium.

In summary, time value is a critical aspect of option pricing. It reflects the remaining time to exercise an option and decays as the option gets closer to expiration, which can significantly impact the option’s price.
