Options Payoff Matrix

Build the expiry payoff of a two-leg options strategy across a spot grid - per-leg and total P&L, net debit, max profit, max loss and breakeven - then read the risk off a payoff diagram.

The scenario

A two-leg options strategy lands on your desk and the head trader wants the picture before it goes on the book: what does it pay at expiry, where does it break even, and what's the most it can make or lose? Build the payoff matrix across a spot grid and draw the diagram.

Where this shows up

Reading a structure's payoff, breakeven and capped risk/reward on the fly is bread-and-butter for options-trading interviews at firms of this type.

Task brief

# Options Payoff Matrix

**Role relevance:** Options trading-desk take-home.
**Estimated time:** 45-50 minutes  ·  **Difficulty:** Intermediate  ·  **Format:** Excel (.xlsx)

## What you are given
- `options_payoff_matrix_starter.xlsx` - a Brief tab, a Formula Help tab, the strategy legs and a payoff-grid template. Amber cells are yours to complete.

## What you must deliver
1. Per-leg P&L at expiry across the spot grid
2. Total P&L, then net debit, max profit, max loss and the breakeven
3. A payoff diagram
4. One line interpreting the risk/reward

## Constraints
- Formula-driven from the leg inputs; short legs carry a negative quantity.

## Submission note
Use the Formula Help tab; the solution workbook shows every formula and the diagram.

Your tasks

  1. 01Compute each leg's P&L at expiry across the spot grid: Qty × (intrinsic − Premium).
  2. 02Sum the legs to the strategy's Total P&L at each spot.
  3. 03Compute the net debit, max profit, max loss (MAX/MIN) and the breakeven.
  4. 04Read the payoff diagram (it fills from the Total column) and write a one-line interpretation.

What you'll learn

  • How a multi-leg payoff is just the sum of its legs' payoffs.
  • Why a bull call spread is defined-risk and capped-reward — and where it breaks even.
  • How to read risk/reward straight off a payoff diagram.
