How Options Are Priced

6 min

Option prices depend on several things: the current stock price, your chosen strike price, how much time is left, and how much the stock tends to move up and down.

Intrinsic Value vs. Time Value

Intrinsic value is the profit you'd make if you exercised right now. Time value is the extra premium based on potential future movement. Option Premium = Intrinsic Value + Time Value.

In-the-Money, At-the-Money, Out-of-the-Money

In-the-Money (ITM): The option already has real value. For calls, this means the stock price is above your strike price. At-the-Money (ATM): The stock price equals your strike price. Out-of-the-Money (OTM): The option has no real value yet—you're hoping the stock moves your way.

Call $90 strike
Stock XYZ at $100 - ITM
$10 intrinsic + time value
Call $100 strike
Stock XYZ at $100 - ATM
Only time value
Call $110 strike
Stock XYZ at $100 - OTM
Only time value

Time Decay (Theta)

Options lose value as expiration approaches. This is called time decay or theta. Options with more time until expiration cost more because there's more opportunity for the stock to move in your favor.

Key Takeaways
  • Option premium = intrinsic value + time value
  • ITM options have real value; OTM options only have time value
  • Options decay in value as expiration approaches (theta)
