A stock is at ₹520. You're looking at a call with a ₹500 strike, priced at ₹32. The stock is only ₹20 above the strike, so what is the other ₹12 paying for?
That's a useful way into intrinsic value vs time value. The ₹20 is the call's intrinsic value in this example. The remaining ₹12 is its time value, often called extrinsic value. Together, they make up the ₹32 premium.
Let's keep that call open on our imaginary screen and see what the numbers mean. Later, we'll let the stock rise another ₹5. You might expect the call buyer to be in profit by then, but that depends on more than the stock price.
Keep these three prices separate
The premium is the price of the option. It’s different from the underlying price and the strike price. A share might trade at ₹520 while a call has a ₹500 strike and a ₹32 premium. Those three numbers have separate jobs.
For a purchase, multiply the quoted premium per unit by the applicable quantity to understand the premium outlay before charges. Don’t multiply the strike by the lot size and mistake that amount for the premium you’re paying.
Neostox's options-contract introduction explains the identity and quantity checks. Once those are clear, you can ask what portion of the quoted premium is intrinsic and what portion is extrinsic.
Break down the ₹32 call
For a call, intrinsic value is the greater of zero and underlying price minus strike price. With an underlying at ₹520 and a strike of ₹500, that gives ₹20 per unit.
If the same call's quoted premium is ₹32, its time value in this simplified breakdown is ₹32 − ₹20 = ₹12. The full ₹32 premium isn’t intrinsic value merely because the option is in the money.
Now suppose the underlying is ₹490 while the strike remains ₹500. The calculation would produce a negative difference, but intrinsic value isn’t recorded as negative. It’s zero. The call is out of the money, and a positive premium before expiry represents extrinsic value.
These calculations explain why the strike matters to the premium breakdown. Neostox's guide to choosing an option strike adds context on how contracts at different strikes can behave. Use it to understand the comparison rather than treating a lower quoted premium as an automatic reason to buy.
Try the subtraction with a put
For a put, reverse the subtraction: intrinsic value is the greater of zero and strike price minus underlying price. A ₹500-strike put with its underlying at ₹470 has ₹30 of intrinsic value per unit.
If that put's premium is ₹42, its time value is ₹12. If the underlying later stands above the strike, the put has zero intrinsic value at that observation, even though it may still carry a positive premium before expiry.
Use a single, consistent timestamp for the underlying and premium. Mixing yesterday's underlying close with a premium from this morning can produce a misleading breakdown. Rounding and the exact reference used by the platform can also affect comparisons.
Time value is a convenient name for the portion of premium above intrinsic value. It doesn’t depend only on how many days are left. Implied volatility and other pricing inputs also matter.
Time and implied volatility influence the premium alongside underlying price. Two otherwise comparable contracts can therefore have different extrinsic values. When studying their price changes in a charting workspace, keep the contract and timestamp visible so you can distinguish an actual change from an accidental switch of instrument.
A contract with more remaining time often carries more time value than a comparable shorter-dated contract, but don’t turn that tendency into a price guarantee. Check that the underlying, strike, option type and other relevant conditions are comparable.
The amount can also change during a single day. Saying that an option has ₹12 of time value now doesn’t mean it must retain ₹12 until the next morning or lose it in equal daily instalments.
The stock rises, but the buyer still loses
Return to the hypothetical ₹500-strike call bought for ₹32 when the underlying was ₹520. Suppose you later sell the call for ₹25 while the underlying is ₹525. The call remains in the money, with ₹25 of intrinsic value at that observation.
But the premium trade has lost ₹7 per unit before charges: ₹25 received minus ₹32 paid. The underlying rose, and the contract remained in the money, yet the buyer did not make a profit.
For a simplified long-call payoff at expiry, ignoring charges and contract-specific settlement mechanics, the break-even underlying level is strike plus premium paid. In this example that is ₹532. This is an expiry-payoff calculation, not a rule that governs every possible sale before expiry.
Before expiry, the call's sale premium can include remaining time value. That’s why the price at which you exit the option matters separately from the underlying's relationship to the strike.
Consider a ₹500-strike call while the underlying is ₹490. Its intrinsic value is zero. If the premium is ₹8, the buyer still pays ₹8 per unit, before charges, for a contract whose value depends on what happens during its remaining life.
If the contract finishes out of the money, that premium can be lost entirely. A low quoted premium is therefore not a measurement of low risk. Ask how much you could lose across all the units you bought.
Conversely, a larger premium isn’t automatically worse value. Some of it may be intrinsic value. Comparing two options only by their small displayed prices skips the structure of what each contract represents.
Try it with one contract in front of you
Keep the component values per unit until the final step. Then multiply by the same quantity if you want position totals. Mixing per-unit intrinsic value with total premium outlay creates an incorrect subtraction. Write the unit beside each number, especially when a platform switches between lots and units.
Choose one call and one put to observe. Record underlying, strike, expiry, premium, timestamp and quantity. Calculate intrinsic value with the correct subtraction, then subtract it from the premium to estimate the remaining time value.
You can study contracts with Neostox's options-chain tools. Its website currently states that market prices are delayed by 30 days. Keep all observations within the same time context, and don’t treat a delayed practice quote as a current executable price.
Look back at the ₹32 call. You can explain the original price as ₹20 of intrinsic value and ₹12 of time value. If you later sell it for ₹25, you've lost ₹7 per unit before charges, even though the call is still in the money.
That's the distinction to keep beside your next practice trade. Write down what the contract is worth relative to its strike, then what you paid and received. Those numbers answer different questions, and you need both.
