Moneyness & Payoffs: ITM/ATM/OTM and the Four Shapes

November 04, 2026

// TL;DR

Moneyness is where the strike sits vs the spot. For a CALL: in-the-money (ITM) = strike below spot, at-the-money (ATM) = strike ≈ spot, out-of-the-money (OTM) = strike above spot (reversed for puts). Every premium = INTRINSIC VALUE (the real in-the-money amount; zero for ATM/OTM) + TIME VALUE (everything else, the 'hope', which decays to zero by expiry). Real BS example (Nifty 24000, 7d, IV 12%): 23800 CE = 300 pts (200 intrinsic + 100 time), 24000 CE = 176 pts (all time value), 24200 CE = 90 pts (all time value). The four payoff shapes: long call (loss capped, upside large), long put (mirror), short call (premium in, unlimited loss up), short put (premium in, big loss down). Every strategy later is these four lines added together.

Two ideas in this lesson — moneyness and payoffs — and once they are in your bones, reading an option chain becomes second nature.

Moneyness: where the strike sits

Moneyness, ITM, ATM and OTM. On a number line of strikes around spot 24000: for calls, in-the-money means strike below spot (23800), at-the-money means strike about equal to spot (24000), out-of-the-money means strike above spot (24200). Every option premium has two parts: intrinsic value, the real in-the-money amount (for a 23800 call with spot 24000 that is 200 points, and an OTM or ATM option has zero intrinsic value), plus time value, the rest you pay for the hope it moves your way before expiry. Worked example with real Black-Scholes, Nifty 24000, 7 days, IV 12 percent: 23800 CE is 300 points being 200 intrinsic plus 100 time, 24000 CE is 176 points all time value, 24200 CE is 90 points all time value. At expiry time value is zero and only intrinsic value remains, which is why OTM options can go to zero.

Moneyness just describes where the strike is relative to the current spot price:

  • ITM (In The Money) — the option already has real value if exercised now. A call is ITM when strike < spot; a put is ITM when strike > spot.
  • ATM (At The Money) — strike ≈ spot. The most actively traded, and the most sensitive to time and volatility.
  • OTM (Out of The Money) — no value if exercised now. A call is OTM when strike > spot; a put is OTM when strike < spot. These are cheap, and most of them expire worthless.

The two parts of every premium

This is the single most useful mental model for a premium:

premium = intrinsic value + time value
  • Intrinsic value is the real, in-the-money amount — max(spot − strike, 0) for a call. It cannot go negative. An ATM or OTM option has zero intrinsic value.
  • Time value is everything else — the market’s price for the hope that the option moves your way before expiry. It is highest for ATM options and it decays to zero by expiry (this is theta, Lesson 4).

With real Black-Scholes numbers (Nifty spot 24,000, 7 days to expiry, IV 12%):

23,800 CE = 300 pts  = 200 intrinsic + 100 time value   (ITM)
24,000 CE = 176 pts  =   0 intrinsic + 176 time value    (ATM — ALL time value)
24,200 CE =  90 pts  =   0 intrinsic +  90 time value    (OTM — ALL time value)

Notice: when you buy that ATM or OTM call, you are paying for pure hope — time value that will melt to zero if the market does not move. That is why “cheap” OTM options are not actually cheap in any useful sense; they are usually a bet that is very likely to lose.

The four payoff shapes

Now the shapes. A payoff diagram plots your profit/loss (y-axis) against the underlying’s price at expiry (x-axis). Four shapes cover the basic building blocks — learn them cold.

The four basic payoffs, profit above the line and loss below. Long call, buying a call: flat loss capped at the premium until the strike, then rising unlimited upside. Long put, buying a put: high profit as price falls on the left, flat loss capped at premium on the right. Short call, selling a call: flat premium profit until the strike, then unlimited loss as price rises. Short put, selling a put: large loss if price falls on the left rising to a flat premium profit. Read every strategy as a combination of these four: a long call makes money as price rises with loss capped at the premium, a long put is the mirror paying as price falls, and selling flips the picture collecting premium but with unlimited or large loss. Every spread, straddle and condor later is two or more of these four lines added together.

  • Long call (you buy a call): flat loss (the premium) until the strike, then profit rising with the price. Loss capped, upside large.
  • Long put (you buy a put): the mirror — profit as the price falls, loss capped at the premium.
  • Short call (you sell a call): flat profit (the premium) until the strike, then loss that keeps growing — unlimited to the upside.
  • Short put (you sell a put): flat profit (the premium) on the upside, large loss as the price falls.

A little Python to draw any of these:

import numpy as np
import matplotlib.pyplot as plt

def long_call(spot, strike, premium):
    return np.maximum(spot - strike, 0) - premium

spot = np.linspace(23000, 25000, 400)
pnl  = long_call(spot, strike=24000, premium=176)   # in points

plt.axhline(0, color="grey", lw=1)
plt.plot(spot, pnl)
plt.title("Long 24000 Call payoff at expiry")
plt.xlabel("Nifty at expiry"); plt.ylabel("P&L (points)")
plt.show()
# breakeven = strike + premium = 24176

Every strategy later in this course — spreads, straddles, condors — is literally two or more of these four lines added together. Once you can picture the shapes, you can picture any strategy’s risk instantly.

Pitfalls

  • Buying OTM lottery tickets. They are cheap because they are unlikely to pay. Most expire worthless — you are paying pure time value that decays.
  • Confusing premium with intrinsic value. An ATM option is all time value; you are paying entirely for hope that melts.
  • Reading the payoff at today’s price instead of expiry. Payoff diagrams are at expiry; before that, time value and IV also move the price (Lessons 4–5).

Recap

Moneyness tells you where the strike sits (ITM/ATM/OTM). Every premium splits into intrinsic value (real, in-the-money) plus time value (hope, decays to zero). The four payoff shapes — long/short call, long/short put — are the alphabet of options; every strategy is built from them.

Next: Lesson 4 — The Greeks, where we measure exactly how an option’s price moves — and meet theta, the melting ice cube.
