Original comparison · Reviewed 28 August 2026
Iron condors and iron butterflies both profit from a quiet market, but they disagree about how quiet, and where.
Both are four-leg, defined-risk, neutral strategies built from a call spread and a put spread. The difference is where the short strikes sit — and that single choice reshapes credit, breakeven width, and the odds of winning.
Iron condor: structure
Sell an out-of-the-money put, buy a further OTM put (the put spread). Sell an out-of-the-money call, buy a further OTM call (the call spread). All four legs share one expiration. Those two halves are just a bull put spread and a bear call spread opened together, so the condor's credit, width, and assignment behaviour follow directly from how each of those credit verticals behaves on its own.
Example: Stock at $500. Sell the $480 put, buy the $470 put. Sell the $520 call, buy the $530 call. Net credit received: $3.00.
- Upper breakeven = short call strike + net credit = $520 + $3 = $523
- Lower breakeven = short put strike − net credit = $480 − $3 = $477
- Max profit = net credit ($3.00), earned anywhere between $480 and $520 at expiration
- Max loss = spread width − net credit = $10 − $3 = $7.00
Frequently asked questions
What's the structural difference between an iron condor and an iron butterfly?
An iron condor sells an out-of-the-money put and an out-of-the-money call, each protected by a further OTM long option. An iron butterfly sells an at-the-money put and an at-the-money call at the same strike, protected by OTM long options. The condor has two short strikes; the butterfly's short strikes converge at one.
Which pays a larger credit, iron condor or iron butterfly?
The iron butterfly, because its short strikes sit at-the-money where option premium is richest. The iron condor's OTM short strikes collect less premium, but that trade-off buys a much wider profit zone.
Which has a wider breakeven range?
The iron condor. Its plateau-shaped profit zone spans the distance between its two short strikes. The iron butterfly's profit zone is a narrow triangle peaking at a single strike, so it needs the underlying to land close to that price.
Is one strategy safer than the other?
Both cap maximum loss at the width of a spread minus the credit received, so neither has open-ended risk. The iron condor's wider profit zone gives it a higher probability of finishing profitable; the iron butterfly's larger credit gives it a better payout if the underlying pins near the center strike.
When would I choose an iron butterfly over an iron condor?
Choose the iron butterfly when you expect the underlying to settle very close to a specific price (for example, near a pin level going into expiration) and want the larger credit. Choose the iron condor when you expect the underlying to stay within a broader range but aren't confident about a precise settlement price.
Iron butterfly: structure
Sell an at-the-money put and an at-the-money call at the same strike (the "body"). Buy an OTM put and an OTM call further out (the "wings"), all one expiration.
Example: Same $500 stock. Sell the $500 put and $500 call, buy the $480 put and $520 call. Net credit received: $9.00 — roughly triple the condor's credit, because at-the-money options carry far more time value.
- Upper breakeven = body strike + net credit = $500 + $9 = $509
- Lower breakeven = body strike − net credit = $500 − $9 = $491
- Max profit = net credit ($9.00), earned only if the stock finishes exactly at $500
- Max loss = spread width − net credit = $20 − $9 = $11.00
The core trade-off: credit vs. profit-zone width
In the example above, the iron condor's profit zone is $40 wide ($480–$520); the iron butterfly's zone where it earns any profit is $18 wide ($491–$509), and full max profit only at one price. The butterfly collects three times the credit, but demands a far more precise forecast.
| Iron condor | Iron butterfly | |
|---|---|---|
| Short strikes | Two, both OTM | One, at-the-money |
| Net credit | Smaller | Larger |
| Profit-zone shape | Flat plateau | Narrow triangle |
| Vega exposure | Lower | Higher (short ATM options) |
| Probability of any profit | Higher | Lower |
| Payout if underlying pins the center | Lower | Higher |
Greeks and volatility sensitivity
Because the iron butterfly's short legs sit at-the-money, it carries higher vega than the iron condor — an unexpected rise in implied volatility hurts the butterfly more, since its short options were priced with more extrinsic value to begin with. Both structures have positive theta (they profit from time decay while the underlying stays range-bound), but the butterfly's decay curve is steeper near the body strike.
How to choose
- Pick the iron condor when you have a directional range in mind (for example, "this stays between $480 and $520") but no strong view on exactly where it settles inside that range.
- Pick the iron butterfly when you have a specific price you expect the underlying to gravitate toward — common around known pin levels, quarter-end rebalancing, or after a volatility-crushing event — and you want to be paid more for that conviction.
- Both are worth avoiding around known binary catalysts (earnings, FDA decisions) unless the strategy is specifically built to trade the post-event volatility crush.
