# Payoff Diagram Builder - Multi-Leg Options P&L Source: https://theoptionsbench.com/payoff-diagram-builder/ > Plain-text mirror for AI/LLM ingestion. Canonical HTML page: https://theoptionsbench.com/payoff-diagram-builder/ --- Payoff diagram builder - key facts Plot the expiration profit and loss of any options position - up to four call or put legs - and read its max profit, max loss and breakevens straight off the combined curve. What it plots The combined P&L of up to four long or short call/put legs at expiration, across every underlying price. Max profit / loss The highest and lowest points of the combined payoff - at a strike or at zero - or "Unlimited" when a side is uncapped. Breakevens Every price where the combined P&L line crosses zero. Net credit / debit Premium collected on short legs minus premium paid on long legs - the cash to open. Scope Option legs only, at expiration, before commissions - not a before-expiry or stock-plus-option model. Want the full explanation? Read the Options Profit Calculator overview . ## How this builder works Each leg you add is a single option - a long or short call or put - with its own strike, premium and contract count. The builder works out the profit or loss of every leg at a given underlying price, adds them together, and plots the result across the whole price range. Long legs cost you their premium; short legs pay you theirs. Because an option's value at expiration is a straight line once it is in or out of the money, the combined payoff is always made of straight segments that bend at the strike prices. Max profit and max loss therefore sit at one of those bends - or run off to infinity when a side of the position is uncapped. Breakevens are simply the prices where the line crosses zero. ## What a payoff diagram shows A payoff diagram answers one question: if I hold this position to expiration, what is my profit or loss at each possible stock price? The horizontal axis is the underlying price; the vertical axis is dollars of profit or loss. Where the line sits above zero you make money; below zero you lose. It is the clearest way to compare two structures before you trade - a wide condor against a tight one, or a spread against a single option. ## Reading the diagram - Flat sections are price ranges where your P&L does not change - every option there is either fully in or fully out of the money. - Sloped sections are where the position gains or loses as the stock moves. - Kinks happen exactly at strike prices, where one leg switches between worthless and in-the-money. - Zero crossings are your breakevens. - A line that keeps rising or falling at the edge of the chart means an unlimited profit or loss on that side. ## Worked example A fixed, hypothetical illustration - not live market data. It matches the position the builder loads with so you can follow the math. The builder loads a bull put spread on a hypothetical stock trading at $100: a short put at the $95 strike collecting $2.00, and a long put at the $90 strike costing $1.00. - Net credit: $2.00 collected - $1.00 paid = $1.00 per share, or $100. - Max profit: $100 - if the stock holds at or above $95 both puts expire worthless and you keep the credit. - Max loss: $400 - at $90 or below. The strikes are $5 apart ($500), less the $100 credit. - Breakeven: $94 - the short $95 strike minus the $1.00 credit. That is the signature shape of a defined-risk credit spread: a flat profit shelf to the right, a flat loss floor to the left, and one sloped section between the strikes. ## ⚠ Common mistakes - Reading it as a before-expiration picture. The diagram is the expiration outcome. Before then, time value rounds off the kinks. - Forgetting commissions. A four-leg position pays four commissions to open and potentially more to close. The diagram is before fees. - Ignoring early assignment. A short leg that goes in-the-money can be assigned before expiration, especially around ex-dividend dates. - Misjudging unlimited risk. More short calls than long calls means the loss has no ceiling as the stock climbs. - Confusing net credit with max profit. They are equal for a simple credit spread, but not for every structure. - Unbalancing the legs by accident. Different contract counts on each leg change the shape - a ratio spread is not a vertical spread. ## Frequently asked questions What is an options payoff diagram? It is a chart of a position's profit or loss at expiration across the full range of underlying prices. The flat and sloped sections show exactly where the position makes money, loses money, and breaks even. How many legs can I add? Up to four option legs - enough for vertical spreads, straddles, strangles, butterflies and iron condors. Set a leg's type to "None" to leave it out of the position. How are max profit and max loss calculated? The builder evaluates the combined P&L at every strike and at a zero underlying price; the highest is the max profit and the lowest is the max loss. If the position holds more long calls than short calls, the upside is unlimited. What does net credit or net debit mean? It is the cash to open the position: you collect premium on short legs and pay it on long legs. A net credit pays you up front; a net debit costs you up front. Does this include stock positions or commissions? No. It models option legs only, at expiration, before commissions and fees. For stock-plus-option trades such as a covered call, use the covered call or cash-secured put calculators. Why does my position show an unlimited loss? A combination with more short calls than long calls loses more and more as the stock rises, with no cap. A naked short call is the classic example. The builder flags this as "Unlimited". Is the diagram the position value before expiration? No. It shows profit and loss exactly at expiration. Before expiration, time value and implied volatility make the real curve smoother and rounded; this tool shows the final-day outcome.
