A payoff diagram is a chart that shows how much an option position makes or loses at expiration for every possible price of the underlying. The horizontal axis is the underlying price; the vertical axis is profit or loss. Payoff diagrams make complex strategies easy to understand at a glance: where the break even points are, what the maximum gain and loss are, and which price ranges help or hurt you. They are the fastest way to check whether a trade matches your view.

## The four building blocks

Every option strategy is built from four basic shapes:

| Position | Shape |
|---|---|
| Long call | Flat loss (the premium) below the strike, then rising one for one |
| Short call | Flat gain (the premium) below the strike, then falling one for one |
| Long put | Rising one for one as price falls below the strike, flat loss above |
| Short put | Falling one for one below the strike, flat gain above |

The long call and long put shapes are drawn in [Calls and Puts](https://learn.tradelabsai.com/options/calls-and-puts/).

## How to draw a payoff diagram

1. **List each leg:** type (call or put), long or short, strike, premium and quantity.
2. **Pick a range of prices** for the underlying at expiration, including every strike.
3. **Calculate each leg's profit or loss** at each price. A long call makes max(S minus K, 0) minus its premium, a long put makes max(K minus S, 0) minus its premium, and a short leg makes the negative of the matching long figure.
4. **Add the legs together** at each price.
5. **Plot the totals** and mark the break evens, maximum profit and maximum loss.

**Example: Drawing a bull call spread**
Buy a $100 call for $4.00 and sell a $110 call for $1.50. Net cost: $2.50.

| Stock at expiry | Long $100 call | Short $110 call | Total |
|---|---|---|---|
| $90 | minus $4.00 | +$1.50 | minus $2.50 |
| $100 | minus $4.00 | +$1.50 | minus $2.50 |
| $102.50 | minus $1.50 | +$1.50 | $0.00 (break even) |
| $110 | +$6.00 | +$1.50 | +$7.50 |
| $120 | +$16.00 | minus $8.50 | +$7.50 |

Maximum loss is $2.50 below $100; maximum gain is $7.50 above $110. Per contract, that is minus $250 and +$750. See [Bull Call Spread](https://learn.tradelabsai.com/options/bull-call-spread/).

## Reading the shape

| Shape | What it tells you | Example strategy |
|---|---|---|
| Upward slope | Bullish | [Long Call](https://learn.tradelabsai.com/options/long-call/), [Bull Call Spread](https://learn.tradelabsai.com/options/bull-call-spread/) |
| Downward slope | Bearish | [Long Put](https://learn.tradelabsai.com/options/long-put/), [Bear Put Spread](https://learn.tradelabsai.com/options/bear-put-spread/) |
| V shape | Profits from big moves either way | [Straddle](https://learn.tradelabsai.com/options/straddle/), [Strangle](https://learn.tradelabsai.com/options/strangle/) |
| Upside down V or plateau | Profits if price stays in a range | [Iron Condor](https://learn.tradelabsai.com/options/iron-condor/), [Iron Butterfly](https://learn.tradelabsai.com/options/iron-butterfly/) |
| Flat sections | Risk is capped in that region | Any spread |
| Slope continuing off the chart | Risk or reward with no cap | Naked short call |

## Expiration vs today

A payoff diagram shows profit or loss at expiration. Before expiration, options still have time value, so the profit and loss curve is smoother and sits between the strikes' kinks. Many platforms draw a "today" line alongside the expiration line. The difference between them is driven by time and volatility, measured by the Greeks. See [The Option Greeks Explained](https://learn.tradelabsai.com/options/the-option-greeks-explained/).

## Payoff diagrams and parity

Payoff diagrams show synthetic relationships visually. A long call plus a short put at the same strike draws a straight diagonal line, the same shape as owning the stock. See [Synthetic Positions](https://learn.tradelabsai.com/options/synthetic-positions/) and [Put-Call Parity](https://learn.tradelabsai.com/options/put-call-parity/).

## Try it yourself

The [Option Payoff Calculator](https://learn.tradelabsai.com/tools/option-payoff-calculator/) lets you enter legs and see the payoff drawn instantly, which is the quickest way to build intuition for spreads and combinations.

## Common mistakes

- **Forgetting premiums** and plotting only intrinsic value.
- **Mixing up long and short legs.**
- **Reading the expiration line as today's profit or loss.**
- **Ignoring the contract multiplier** when sizing.

## Frequently asked questions

### What is an option payoff diagram?

A chart showing the profit or loss of an option position at expiration across a range of underlying prices.

### How do you calculate the break even of an option strategy?

Find the underlying price where the total profit or loss of all legs equals zero. For a single long call it is the strike plus the premium.

### Do payoff diagrams show profit before expiration?

The standard diagram shows expiration only. Before expiry, time value makes the curve smoother, which many platforms show with a separate line.
