Introductory Context
"Intrinsic value is the in-the-money component of premium — what the option would be worth if exercised right now. For calls: max(Spot − Strike, 0). For puts: max(Strike − Spot, 0). OTM options have zero intrinsic value — their entire premium is time value. ITM options have intrinsic value as their floor."
The Definition and Formula
Intrinsic value is the value an option would have if exercised right now. It is the real, current, calculable value — not a guess about the future.
For Call Options
Intrinsic Value = max(Spot Price − Strike Price, 0)
The 'max' function ensures intrinsic value can never be negative — an OTM option has zero intrinsic value, not negative. With Nifty at 24,300:
• 24,000 CE: intrinsic value = 24,300 − 24,000 = ₹300 (ITM by 300 points)
• 24,300 CE: intrinsic value = 24,300 − 24,300 = ₹0 (ATM)
• 24,600 CE: intrinsic value = max(24,300 − 24,600, 0) = ₹0 (OTM)
For Put Options
Intrinsic Value = max(Strike Price − Spot Price, 0)
With Nifty at 24,300:
• 24,600 PE: intrinsic value = 24,600 − 24,300 = ₹300 (ITM for a put)
• 24,300 PE: intrinsic value = 24,300 − 24,300 = ₹0 (ATM)
• 24,000 PE: intrinsic value = max(24,000 − 24,300, 0) = ₹0 (OTM)
Intrinsic Value as the Floor of ITM Options
For ITM options, intrinsic value acts as the floor of the premium — the option can never trade below its intrinsic value in a liquid market. If it did, arbitrageurs would immediately buy the underpriced option, exercise it, and capture a riskless profit, eliminating the underpricing instantly.
This floor relationship means that deep ITM options move almost one-for-one with the underlying. A 22,000 CE with Nifty at 24,300 has ₹2,300 of intrinsic value. If Nifty rises 100 points, the intrinsic value rises to ₹2,400. The option's premium increases by approximately ₹100 per unit — very close to the full underlying move, reflecting the high delta of deep ITM options.
Intrinsic Value Cannot Be Negative — But It Can Disappear
A call option's intrinsic value is zero when the underlying is at or below the strike — it cannot go negative. However, intrinsic value can disappear rapidly if the underlying moves adversely through the strike. An option that was ITM with ₹200 of intrinsic value this morning can become OTM with zero intrinsic value by afternoon if the underlying falls 200 points through the strike. The time value component remains (at whatever level it is), but the intrinsic value goes to zero instantly when the option crosses the strike.
Calculating Intrinsic Value Before Every Trade
Before buying any option, calculate its intrinsic value and time value as a matter of habit. This tells you:
• an option with ₹200 intrinsic and ₹30 time value has ₹200 of value that does not decay. An option with ₹0 intrinsic and ₹80 time value is 100% at risk from theta. How much of your premium is 'real' right now vs how much is 'potential':
• time value ÷ total premium = percentage at risk from theta daily. What percentage of premium is exposed to time decay:
• an ITM option will never trade below its intrinsic value in a liquid market — useful to know when setting limit sell orders. The floor of the option's value:
Example calculation before a trade: Nifty at 24,150. Looking at 24,000 CE at ₹200 premium. Intrinsic value = max(24,150 − 24,000, 0) = ₹150. Time value = ₹200 − ₹150 = ₹50. 25% of premium is time value (at risk from theta). 75% is intrinsic value (real right now). This is a relatively low time value percentage — the option is mostly real value, not hope.
Intrinsic value is what you own. Time value is what you are renting. The distinction changes how you think about every position. An ITM option with high intrinsic value will retain significant value even as expiry approaches. An OTM option with only time value will decay to zero if the underlying does not move. Knowing the composition of your premium tells you the character of the risk you are holding.
