Example Data Table

Example setup: Buy 90 put, sell 95 put, sell 105 call, buy 110 call, receive 2.00 credit, use 1 contract and 100 multiplier.
Underlying Price Payoff per Share Total Payoff Interpretation
90 -3.00 -300.00 Left-side maximum loss.
93 0.00 0.00 Lower breakeven point.
100 2.00 200.00 Maximum profit zone.
107 0.00 0.00 Upper breakeven point.
110 -3.00 -300.00 Right-side maximum loss.

Formula Used

At expiry, the iron condor combines two credit spreads. The payoff per share equals the net credit plus the value of all four option legs.

Short Put Value -max(Short Put Strike − Price, 0)
Long Put Value max(Long Put Strike − Price, 0)
Short Call Value -max(Price − Short Call Strike, 0)
Long Call Value max(Price − Long Call Strike, 0)
Total Payoff per Share Net Credit + Short Put + Long Put + Short Call + Long Call
Total Position Payoff Payoff per Share × Multiplier × Contracts
Lower Breakeven Short Put Strike − Net Credit
Upper Breakeven Short Call Strike + Net Credit
Maximum Profit Net Credit × Multiplier × Contracts
Maximum Loss (Wider Spread Width − Net Credit) × Multiplier × Contracts

For balanced condors, both spread widths are equal. For unbalanced structures, the wider spread controls the maximum loss.

Frequently Asked Questions

1) What does this calculator measure?

It measures the expiry payoff of an iron condor across different underlying prices. It also reports breakevens, maximum profit, maximum loss, and current spot payoff.

2) Why are there four strike inputs?

An iron condor uses four option legs: a long put, short put, short call, and long call. Those legs create a capped-risk, capped-reward payoff structure.

3) What is the maximum profit zone?

Maximum profit usually occurs when the underlying finishes between the two short strikes. In that region, all options expire worthless, so the trader keeps the full net credit.

4) How are breakeven points found?

The lower breakeven equals the short put strike minus the net credit. The upper breakeven equals the short call strike plus the net credit.

5) Why does the wider spread determine risk?

When put and call widths differ, the side with the wider spread can lose more after subtracting the net credit. That wider side sets the maximum possible loss.

6) Is this an expiry-only model?

Yes. This file models payoff at expiration, not interim mark-to-market pricing. It does not include time value, volatility shifts, interest rates, or assignment timing.

7) What multiplier should I use?

For standard U.S. equity options, the multiplier is often 100. Adjust it if your contract type uses a different unit size.

8) Why use a smaller step size?

A smaller step size creates more scenario rows and a smoother payoff curve. Larger step sizes calculate faster but produce fewer plotted points.
