Options Payoff Diagrams, Explained Like a Friend Would
Published · 2 min read
Payoff diagrams look like rocket science. They are not. A plain-English walkthrough of calls, puts, covered calls, and spreads — with numbers at every step.
An options payoff diagram is just a graph of profit at expiration, plotted against the stock price. Two axes, one kink, and a break-even. That is the whole idea.
The only two shapes you need
Buy a call and lose money until the stock clears the strike plus the premium you paid. Buy a put and lose money until the stock falls below the strike minus the premium. Everything else in options is these two shapes, mirrored, combined, or sold instead of bought.
The four positions, in numbers
Below, the stock trades at $100 and every option expires with the stock at that price.
| Position | Max profit | Max loss | Break-even |
|---|---|---|---|
| Buy $105 call for $3 | Unlimited | $300 (the premium) | $108 |
| Buy $95 put for $2.50 | $9,500 | $250 (the premium) | $92.50 |
| Covered call: own 100 shares at $100, sell $105 call for $3 | $800 | $9,700 (stock to zero, less premium) | $97 |
| Bull call spread: buy $105 call $3, sell $110 call $1.50 | $350 | $150 (net debit) | $106.50 |
Read the third row carefully, because it is the most misunderstood trade in retail options. Selling a covered call caps your upside at $800 per contract — ($105 − $100) × 100 + $300 premium — in exchange for $300 of downside cushion.
How to read any diagram in five seconds
- Find the kink — the strike where the line changes slope.
- Read the slope to the right: flat means you capped your upside, rising means you profit as the stock climbs.
- Read the slope to the left: flat at a negative number is your max loss.
- Find where the line crosses zero — that is your break-even.
- Multiply everything by 100, because options come in contracts of 100 shares.
The mistake the diagrams expose
Most bad options trades are not directionally wrong — they are structurally wrong. They buy a shape with capped upside and unlimited risk, sell a shape with unlimited risk and capped reward, or size a position so large that a normal 1-in-5 loss ends the account.
Plot the trade first, then size it: options profit calculator, then the position size calculator.
