Iron Condor vs Iron Butterfly: Break-Evens Explained

Iron condor and iron butterfly na the same four-leg options trade, na just one strike dey move. Each one dey sell two options and buy two options wey dey further out as protection. Both dey pay when the stock remain inside one range. Butterfly dey sell both options for the same strike, so e collect bigger credit but get narrower profit zone. Condor dey separate the two sold strikes and collect smaller credit for wider zone.

Iron condor vs iron butterfly: one strike apart

Both positions na put spread and call spread for the same stock and same expiration date. Short option, na the one wey you sell, dey pay you premium upfront. Long option, na the one wey you buy, dey cost premium and limit how bad the position fit become. When you sell both spreads, money enter from day one. That money na the credit.

Take stock wey dey trade for $100, with expiration 30 days away. Iron butterfly get four legs:

• Buy the 95 put
• Sell the 100 put
• Sell the 100 call
• Buy the 105 call

Iron condor keep the same 5-point wings and separate the two sold strikes:

• Buy the 90 put
• Sell the 95 put
• Sell the 105 call
• Buy the 110 call

Na this be the whole difference. Butterfly short options share one at-the-money strike, where premium dey highest. Condor short options sit 5 points away on both sides, where premium dey thinner. Everything else match: the 5-point wings and expiration date.

How to calculate the break-evens

Break-even na the price where the position finish expiration flat, with no profit and no loss. Both structures get one for each side, and both na simple offset from a sold strike.

For iron butterfly, both break-evens come from the shared short strike:

• Lower break-even na short strike minus the credit
• Upper break-even na short strike plus the credit

For iron condor, each sold strike get its own:

• Lower break-even na short put strike minus the credit
• Upper break-even na short call strike plus the credit

Suppose the butterfly above open for $2.60 credit and the condor for $1.30, both quoted per share, with one contract covering 100 shares. Those na round example numbers, no be quotes from any chain. Butterfly break even at $97.40 and $102.60, with profit zone wey wide $5.20. Condor break even at $93.70 and $106.30, with zone wey wide $12.60. Butterfly collect twice the premium across zone wey less than half the size.

Max loss follow one rule for both: wing width minus credit. Butterfly risk $5.00 minus $2.60, wey be $240 per contract, against maximum profit of $260. Condor risk $5.00 minus $1.30, wey be $370 per contract, against $130. The wider zone cost more per contract for days wey stock comot from the zone. Another difference dey inside the zone itself. Butterfly reach maximum only if stock finish exactly for $100, while condor keep the full credit anywhere between $95 and $105.

Is the profit zone wider than the expected move?

Break-even levels alone no fit decide which structure suit a particular chart. The test wey matter na profit-zone width against expected move, meaning the size of move wey options don already price in for the same holding period. Our expected move from implied volatility guide explain the calculation: annual implied volatility multiplied by the square root of the fraction of one year wey you hold am.

Across May 2026, these chains price 30-day moves of 4.43% of spot for the quiet end, on SPY, reaching 19.65% on AMD. Same structure, but the room to work different well-well.

Now apply the test to the example. Expected move of 5% on $100 stock cover $95 to $105, a range wey wide $10. Butterfly $5.20 zone cover 0.52 of that range. Condor $12.60 zone cover 1.26 of am. Same stock, same wings, and only one of them remain profitable across the move wey the chain don already price in. Butterfly pay in full when the tape quiet pass that pricing, and e pay roughly twice as much on the days wey stock land there.

Why the butterfly's credit is bigger

Option premium no dey flat across strikes. E dey peak at at-the-money and fall away on both sides. That pattern na the main reason behind the credit difference.

Averaged across the month, SPY call wey expire in 30 days and strike at the money close at $13.55. The call wey strike +6% from spot close at $0.72, while the put wey strike -6% from spot close at $2.74. The panel draw tent shape. Everything butterfly sell dey for the peak, while everything condor sell dey down the slope. The credit gap for the example na that shape measured in dollars. For how the chain prices come from, see how to read an option chain.

Which one carries more volatility risk?

Vega measure how much option price move when implied volatility move by one point, and option vega explain am in detail. Vega follow the same tent shape as premium: e highest at the money, smaller as strikes move away, and bigger when more time remain on the contract.

Each bucket dey indexed to the at-the-money reading for its own expiration range. That put both curves on one scale starting at 100. At 25 to 35 days out, strike 6% above spot carry 33% of the at-the-money vega. At 7 to 14 days out, the same strike carry 7%. Butterfly sell the peak of that curve two times. Condor sell two points down the slope. If implied volatility rise after the trade enter, e mark down butterfly short body more sharply. The same asymmetry work in butterfly favour through IV crush, meaning the fall in implied volatility wey often follow scheduled event.

What four legs cost to get filled

Each structure na four contracts to open. If you no hold am till expiration, you fit need up to four more to close. Every leg cross bid-ask spread, and spread width follow how much of the chain dey actually trade. Our liquid vs volatile options guide separate chain wey dey move plenty from chain wey dey trade plenty. Na the second one dey determine fills.

For average May 2026 session, SPY get 268 strikes with 20 to 45 days remaining wey print at least one contract, and 171 of them trade 100 lots or more. For the thin end of the group, KO show 32 strikes wey trade, and 9 of them trade 100 lots or better. Condor need four separate strikes before e fit trade. Butterfly need three, with double size for the middle strike. For chain where only few dozen strikes print during one session, the strikes wey either structure need fit be among the ones wey never trade at all. Commissions still dey on top, and what it costs to trade options break down the cost per contract side.

FAQ

Wetin be the difference between iron condor and iron butterfly?

Both dey sell put spread and call spread for one expiration. Iron butterfly sell both short options for the same strike, usually at the money. Iron condor separate them, with one strike below the stock and one above. Butterfly collect bigger credit, while condor get wider profit zone.

How you calculate break-even for iron butterfly?

Take the shared short strike. Subtract the credit to get lower break-even, then add the credit to get upper break-even. Butterfly for 100 strike wey open for $2.60 credit break even at $97.40 and $102.60, with profit zone wey wide $5.20.

How you calculate break-even for iron condor?

Subtract the credit from short put strike, and add the same credit to short call strike. Condor wey short the 95 put and 105 call for $1.30 credit break even at $93.70 and $106.30, with zone wey wide $12.60.

Which one lose more, iron condor or iron butterfly?

Max loss for both na wing width minus credit. So when the wings match, structure wey collect less premium dey risk more. With 5-point wings, the $2.60 butterfly risk $240 per contract, while the $1.30 condor risk $370. Condor only reach that maximum after stock make a bigger move.

Iron butterfly get more vega risk?

Yes. Vega peak for at-the-money strike, and butterfly sell two options there. Condor short strikes dey further out, where vega na only fraction of the peak, as the indexed ladder above show.
