Consider a hypothetical example in which the price of the underlying asset is 10,000 yen and a call option (call) with a strike price of 9,500 yen has a premium of 700 yen. The intrinsic value is 500 yen and the time value is 700 − 500 = 200 yen. For an option with zero intrinsic value, the whole premium is time value. Time value does not fall at a constant pace; it falls faster just before expiry.
