Time Value

Time value (also called extrinsic value) is the portion of an option's premium that exceeds its intrinsic value. It represents what traders are willing to pay for the possibility that the option could become more profitable before expiration. An out-of-the-money option is entirely time value since it has no intrinsic value.

Why It Matters

Time value is what makes options trading fundamentally different from stock trading. When you buy an option, time works against you — every day, a small amount of time value evaporates. When you sell an option, time works in your favor. This is the basis for the entire category of theta-positive strategies like covered calls, credit spreads, and iron condors.

Understanding time value helps you make better trade decisions. Paying a lot of time value means you need a bigger move to profit. Collecting time value means you can profit even if the stock does not move at all.

How It Works

An option's price has two components: intrinsic value and time value. Intrinsic value is the amount the option is in the money. Time value is everything else.

Option Price = Intrinsic Value + Time Value

What drives time value:

• Time to expiration: More time means more time value. A 90-day option has more time value than a 30-day option at the same strike, because more time means more opportunity for the stock to move.
• Implied volatility: Higher IV means more time value. If the market expects big moves, it prices more time value into options.
• Moneyness: ATM options have the most time value. Deep ITM and deep OTM options have less time value.
• Interest rates and dividends: These have smaller effects but do influence time value through rho and dividend expectations.

Time value decay is not linear. Options lose time value slowly at first and then rapidly as expiration approaches. The last 30 days see the steepest decay, and the final week is where the most dramatic erosion happens. This is why many sellers target the 30-45 day range — they capture the acceleration in decay while leaving room for adjustment.

At expiration, time value is zero. Every option is worth either its intrinsic value or nothing. This is why option sellers want time to pass quickly and option buyers need the stock to move before time runs out.

Quick Example

Stock GHI trades at $100. The $95 call expiring in 60 days trades at $8.50.

Intrinsic value: $100 - $95 = $5.00 (the option is $5 in the money) Time value: $8.50 - $5.00 = $3.50

You are paying $3.50 above the option's intrinsic worth for the chance that GHI moves even higher. If you hold until expiration and the stock is still at $100, the call is worth exactly $5.00 — all $3.50 of time value has evaporated.

An OTM $105 call trading at $2.00 is entirely time value. If the stock stays at $100, that $2.00 goes to zero.
