The sensitivity of the option value to the amount of time to expiry is known as the option's theta. The option value will never be lower than its IV. As seen on the graph, the full call option value (IV + TV), at a given time t, is the red line. [5]
The change in option value is typically negative because the passage of time is a negative number (a decrease to , time to expiry). However, by convention, practitioners usually prefer to refer to theta exposure ("decay") of a long option as negative (instead of the passage of time as negative), and so theta is usually reported as -1 times the ...
This extra money is for the risk which the option writer/seller is undertaking. This is called the time value. Time value is the amount the option trader is paying for a contract above its intrinsic value, with the belief that prior to expiration the contract value will increase because of a favourable change in the price of the underlying asset.
For an option, theta is typically negative, reflecting the loss in value due to having less time for exercising the option (for a European call on an underlying without dividends, it is always negative). Gamma is typically positive and so the gamma term reflects the gains in holding the option.

The time value of money is the idea that receiving a given amount of money today is more valuable than receiving the same amount in the future due to its potential earning capacity.

The following factors reduce the time value of a put option: shortening of the time to expire, decrease in the volatility of the underlying, and increase of interest rates.
