Understanding How Options Are Priced
An option premium is the price that traders pay for a put or call options contract. The price you pay for this right is called the option premium.
As a result, time value is often referred to as an option's extrinsic value since time value is the amount by which the price of an option exceeds the intrinsic value.
How are option premiums calculated? For call options, intrinsic value is calculated by subtracting the option premium is determined price from the underlying price.
An option premium is the current market price of an option contract.
For put options, the opposite is true — intrinsic value is calculated by subtracting the underlying price from the strike price. The longer an option has before it expires, the more time the underlying market has to pass the strike price, and vice versa.

Falling time value is known as time decay, a risk that options traders need to manage.
