What Is Time Decay
The steady decline in an option’s extrinsic (time) value as the end date approaches is represented by time decay, also known as theta decay. There are two parts to an option’s price:
- Intrinsic Value: It is the gap between the price of the base asset and the strike price.
- Time Value: The extra money due to the chance that the price will go up before the contract expires.
The time worth goes down as time goes on because the chance of a significant change in price goes down. This decay happens even if the price of the base object stays the same. To understand how options lose value daily, you need to understand the idea of “time decay.”

How Does Time Decay Affect Options Pricing
Theta is a Greek letter that measures how much time has passed. Theta figures out how much an option’s price drops daily, given that all other factors remain the same. In general:
- At-the-Money Options: These typically have a higher time value, meaning that time decay’s effects are more noticeable in their prices.
- In-the-Money and Out-of-the-Money Options: Even though these options have value on their own, the time factor still significantly impacts their prices.
Theta generally goes up as the expiration date gets closer. The option’s time value goes down faster because of this. For sellers, the price of an option may decrease over time due to time decay, regardless of market movements. The gradual loss of time value is an important factor to consider when evaluating options. In other words, as long as the price of the base product doesn’t change a lot.
The Role of Time Decay in Options Strategies
Time decay affects buyers and sellers differently:
For Option Buyers:
Time decay reduces the premium over time, impacting the value of options if the underlying price does not move as anticipated.
For Option Sellers:
The gradual reduction in time value influences the premium received, regardless of market direction.
