Calculate the in-the-money amount before subtracting premium
For an ordinary unadjusted stock option, a call is in the money when S > K; a put is in the money when S < K. At the strike, both have zero intrinsic value. The max function also makes intrinsic value zero for an out-of-the-money option. The following inputs are hypothetical dollars per share, with each premium supplied only to illustrate the decomposition.
- The call is $5 in the money and the put is $8 in the money. Those dollar amounts do not say whether either position is profitable after the entry premium.
- For one contract with a verified multiplier of 100, the call premium is $720, consisting of $500 intrinsic and $220 extrinsic value before fees. Two identical contracts double each amount.
- The 100 multiplier is an assumption for this example. Adjusted contracts can deliver a different share count, cash or other assets. Use the full deliverable specification instead of applying the simple stock formula to an adjusted ticker.
| Contract | S / K | Intrinsic calculation | Premium | Extrinsic remainder |
|---|---|---|---|---|
| ITM call | $105 / $100 | max(105 - 100, 0) = $5 | $7.20 | $2.20 |
| ITM put | $92 / $100 | max(100 - 92, 0) = $8 | $10.30 | $2.30 |
| ATM call or put | $100 / $100 | $0 | $3.10 | $3.10 |
| OTM call | $95 / $100 | max(95 - 100, 0) = $0 | $1.40 | $1.40 |
| OTM put | $105 / $100 | max(100 - 105, 0) = $0 | $1.25 | $1.25 |
