Iron Condor Calculator
An iron condor sells an out-of-the-money put spread and call spread at once. You collect a credit and keep it if the stock stays between the short strikes - a defined-risk, range-bound income trade.
Strategy
Collect a credit if the stock stays in a range; defined risk.
Market inputs
Changing the price, IV or DTE keeps your legs. Use Re-price legs to refresh premiums from Black-Scholes, or Reset to preset to rebuild the iron condor from scratch.
Position legs

Solid line = profit or loss held to expiration (green in profit, red at a loss). Dashed purple line = estimated value today; drag the slider toward expiration to watch time decay pull it onto the expiration line. The grey line marks the current price and the dashed cyan lines mark each breakeven.
Net position Greeks
Profit / loss table
Each cell is your position's profit or loss at that underlying price (rows, high at top) on that date (columns, today through expiration). Green = profit, red = loss; the deeper the colour, the larger the move.

How the iron condor works
An iron condor sells an out-of-the-money put spread and call spread at once. You collect a credit and keep it if the stock stays between the short strikes - a defined-risk, range-bound income trade.
With these inputs you open it for a net credit of $193. Your maximum loss is -$307 and your maximum profit is $193. It breaks even at $93.07, $106.93. The trade makes money when the underlying stays near the current price through expiration.
For education only, not investment advice. Results exclude commissions and assume European-style options priced with the Black-Scholes model; early exercise, assignment and dividends between now and expiration are simplified. Probability of profit is a model estimate, not a guarantee.

Options calculator questions, answered
How does an options profit calculator work?
You build a position out of one or more legs - calls, puts or stock, bought or sold - and the calculator computes the profit or loss at every possible price of the underlying at expiration. It draws that as a payoff diagram, finds the breakeven price(s), the maximum profit and loss, and estimates the probability of profit and the position Greeks. Everything updates instantly as you change the inputs; nothing is sent to a server.
What is a payoff diagram?
A payoff diagram plots your profit or loss (vertical axis) against the price of the underlying stock (horizontal axis). The solid line is the profit or loss if you held to expiration; it is green where you make money and red where you lose. The dashed line shows the position's estimated value at an earlier date - drag the time slider from today to expiration to watch it decay onto the expiration line.
How are breakeven, max profit and max loss calculated?
The tool evaluates the exact expiration payoff of your combined legs across a fine grid of underlying prices. Breakevens are the prices where total profit and loss crosses zero, max profit is the highest point of the payoff and max loss is the lowest. When a payoff keeps rising or falling without bound - like a long call's upside - it is reported as Unlimited.
What is probability of profit?
Probability of profit (PoP) estimates the chance the trade finishes above breakeven at expiration. It assumes the underlying price is lognormally distributed, using the implied volatility, days to expiration and rates you enter. It is a model estimate, not a guarantee, and it is only as good as the volatility assumption you feed it.
Do I need to enter real option prices?
No. You can type the exact premiums from your broker for a precise result, or let the calculator auto-price every leg with the Black-Scholes model from the underlying price, implied volatility and days to expiration you set. Use the Re-price legs button any time to refresh those theoretical prices after changing the inputs.
Is the Iron Condor bullish, bearish or neutral?
The Iron Condor is a neutral strategy. An iron condor sells an out-of-the-money put spread and call spread at once. You collect a credit and keep it if the stock stays between the short strikes - a defined-risk, range-bound income trade. Collect a credit if the stock stays in a range; defined risk.
About this options profit calculator
This free options profit calculator and strategy builder draws the payoff diagram for any combination of calls, puts and stock. Enter the underlying price, implied volatility and days to expiration, then either type the real premiums from your broker or let the tool auto-price each leg with the Black-Scholes model. It computes the breakeven price(s), maximum profit and loss, return on risk, probability of profit and the net position Greeks (delta, gamma, theta, vega and rho), and overlays a mark-to-market curve you can drag from today to expiration to see the effect of time decay. Presets cover the most-used strategies - covered calls, cash-secured puts, verticals, iron condors, straddles, strangles and more - and everything runs in your browser with no sign-up.
