Stock Trading | Options Premiums -- Intrinsic Value and Time Value

The premium you pay or receive for an option is comprised of two parts, The intrinsic value and the time value.

The intrinsic value of the option is determined by the relationship between the strike price of the option and the current stock price.  The intrinsic value is always zero or more.

The time value of an option is any amount in the premium over the intrinsic value.  The time value is determined by the amount of time remaining until expiration of an option and of the volatility of the market in general and the stock price in particular.  Everything else being equal, the time value of an option decreases as expiration approaches, and decreases more rapidly the closer it gets to expiration.  Everything else being equal, the time value of an option increases as volatility increases, and decreases as volatility decreases.

If the Stock Price is LESS THAN the Strike Price,
  the option is Out-of-the-Money (OTM).
    the Intrinsic Value is 0 (zero).
    the Time Value EQUALS the Premium.

          If StockPrice < CallStrikePrice
            IntrinsicValue = 0
            TimeValue = CallPremium

If the Stock Price is GREATER THAN OR EQUAL TO the Strike Price,
  the option is In-the-Money (ITM) -- At-the-Money (ATM) if EQUAL.
    the Intrinsic Value is the Stock Price less the Strike Price.
    the Time Value EQUALS the Premium less the Intrinsic Value.

          If StockPrice >= CallStrikePrice
            IntrinsicValue = StockPrice - CallStrikePrice
            TimeValue = CallPremium - IntrinsicValue
