Iron Condor vs Iron Butterfly: Win Rate, Premium & Strike Geometry (2026)
Same four legs, different geometry. The iron butterfly is a tighter, richer cousin of the iron condor — bigger premium, narrower win range.
What is This comparison?
This comparison Both iron condors and iron butterflies are neutral options strategies that profit from range-bound markets, but differ significantly in profit zone width and max profit potential.
Iron condors offer wider profit zones with lower max profit, while iron butterflies concentrate profit at a single strike with higher max profit but lower win rates.

Feature-by-Feature Comparison
When to Use Iron Condor
Choose iron condor when you expect the stock to stay within a wider range and prioritize higher win rate over max profit. Ideal when IV is high and you want more room for error.
Learn Iron CondorWhen to Use Iron Butterfly
Choose iron butterfly when you expect the stock to pin near a specific price and want higher profit potential with a lower win rate. Best for low-movement scenarios like post-earnings drift.
Learn Iron ButterflyThe Short Version
An iron butterfly is an iron condor with the short strikes pulled all the way to the spot. Both have four legs, both are defined-risk neutral structures, both want the stock to sit still. The butterfly collects roughly 2–3× the credit but only wins if the stock pins close to the short strikes. The condor collects less but has a wide profit zone — usually a 4–6% buffer on each side.
Choose the butterfly when you have high conviction the stock will sit still. Choose the condor when you just want it to not crash. Both are bets on low realised volatility; the butterfly is the more aggressive expression.

| Structure | Sell 530P, Buy 520P, Sell 550C, Buy 560C | Sell 540P, Buy 530P, Sell 540C, Buy 550C |
| Net credit | $2.40 ($240) | $5.80 ($580) |
| Max profit | $240 (anywhere $530–$550) | $580 (only at $540 exact) |
| Max loss | $760 (wing 10 – credit 2.40) | $420 (wing 10 – credit 5.80) |
| Break-evens | $527.60 / $552.40 | $534.20 / $545.80 |
| Profit zone width | $24.80 (4.6% of spot) | $11.60 (2.1% of spot) |
| Probability of profit (POP) | ~65% | ~35% |
| Reward / risk | 0.32× | 1.38× |
| Capital required | $760 per contract | $420 per contract |
The butterfly looks better on every premium metric — bigger credit, smaller capital, better reward-to-risk. It's only worse on the one metric that matters most: how likely it is to win.
Strike Geometry: Why the Butterfly Looks Like a Spike
The iron condor's P&L diagram looks like a wide tabletop with two cliffs. The iron butterfly's P&L diagram looks like a single spike right at the short strike.
| Stock at Expiration | Condor P&L | Butterfly P&L |
|---|---|---|
| $520 (down 3.7%) | -$760 (max loss) | -$420 (max loss) |
| $530 | +$240 (max win edge) | -$420 |
| $535 | +$240 | +$80 |
| $540 (pin) | +$240 | +$580 (max win) |
| $545 | +$240 | +$80 |
| $550 | +$240 | -$420 |
| $560 (up 3.7%) | -$760 | -$420 |
Notice the asymmetry. The condor pays the same $240 anywhere across a 4.6% range. The butterfly only pays its full $580 at one exact price. Step a few dollars away and the butterfly's payout drops fast.
When the Iron Butterfly Wins
The butterfly is the right structure when:
- IV is unusually high. The ATM short strikes carry the most premium. The butterfly extracts the maximum value from elevated IV.
- You have a pin thesis. Stocks anchored to a strike by heavy gamma exposure (think SPX after a major macro event, or single names with deep options market-makers' positioning) tend to pin to the strike. The butterfly is a clean expression of that thesis.
- You want capital efficiency. Butterfly margin is roughly half the condor margin for the same wing width — you can size 2× the contracts on the same buying power.
- Earnings or event drift play. Buying the butterfly cheaply pre-event and closing it after IV crush can produce outsized returns if the stock pins.
When the Iron Condor Wins
The condor is the right structure when:
- You're looking for consistency. The condor's 65% win rate at 16-delta shorts produces a smoother equity curve than the butterfly's 35% win rate.
- You don't have a pin thesis. You just want the stock to not crash. A 4.6%-wide profit zone gives the stock room to wander without breaking the trade.
- You're scaling many tickers. Hard to be high-conviction on pin theses across 20 different names. A diversified portfolio of condors is easier to manage than a portfolio of butterflies.
- You want to roll defensively. The condor's wider profit zone makes it easier to roll one side untouched if the other gets tested. The butterfly's centred geometry means defending a tested side moves you further from the pin.
Backtest: 36-Cycle SPX Roll, 2022–2024
Illustrative narrative: enter both structures at 30 DTE every 30 days. Condor at 16-delta short strikes, butterfly at the ATM strike. Same 50-wide wings. Close at 50% of max profit or 21 DTE.
| Stat | Iron Condor | Iron Butterfly |
|---|---|---|
| Trades | 36 | 36 |
| Winners | 25 (69%) | 12 (33%) |
| Avg winner | +$580 | +$1,820 |
| Avg loser | -$2,100 | -$1,950 |
| Net P&L | +$1,400 | -$960 ... actually +$960 / -$240 |
| Max drawdown | -$4,200 | -$5,850 |
Simulated data for display — illustrative pattern, not a verified live backtest.
The headline: the condor produced steadier P&L; the butterfly produced more variance with a smaller net result. The butterfly's bigger winners didn't offset its lower frequency. In choppy markets like 2022 the butterfly can hit max loss two cycles in a row, which is brutal for the account.
Common Mistakes
Iron condor
- Going too narrow on short strikes for "more premium" — the win rate drops sharply below 16 delta.
- Holding to expiration. Gamma blows up risk-reward in the last 14 DTE.
- Not respecting the wing width — max loss is 4× the credit on a typical setup, so a single bad cycle wipes 4 winners.
- Trading in low IV. Credit too small to justify the locked capital.
Iron butterfly
- Sizing on max profit, not probability. The headline 1.38× reward-to-risk only matters if the stock pins.
- Closing too late. Butterflies decay fast in the final week and can give up a 50%-profit edge overnight.
- Trading on directional names. Butterflies are pure pin bets — they require a sideways thesis.
- Going wing-too-wide. Wider wings reduce capital efficiency without materially improving win rate.
Hybrid: Broken Wing Butterfly
The broken-wing butterfly is a popular hybrid that sits between these two. Same ATM short strikes as the butterfly, but with one wing wider than the other — biasing the trade against one direction. Often opened for a small credit or zero cost, which removes the directional max loss on the protected side entirely. It's the trade for "I think the stock will pin, but if I'm wrong I'd rather be wrong in this direction."
Most retail traders should master the condor first, then experiment with the butterfly on conviction setups, and only graduate to broken-wing variants once they have a stable framework for both base structures.

Frequently Asked Questions
What's the difference between an iron condor and an iron butterfly?
Both are four-leg defined-risk neutral structures. The iron condor sells out-of-the-money short strikes on each side, leaving a wide profit zone. The iron butterfly sells at-the-money short strikes on both sides at the same strike price, creating a tighter but higher-paying setup. The condor wins more often; the butterfly wins less often but pays more per winner.
Which has a higher win rate, iron condor or iron butterfly?
The iron condor. At 16-delta short strikes, the condor has roughly a 65-70% probability of profit. The butterfly's POP is typically 30-40% because the stock has to pin near the short strikes for the full credit to be retained. The butterfly compensates with a higher reward-to-risk ratio per trade.
Is the iron butterfly more profitable than the iron condor?
Per trade, yes — the butterfly has a reward-to-risk of roughly 1.3-1.5x vs the condor's 0.3-0.4x. But the condor wins more often, so net P&L over many cycles is usually higher with the condor unless you have a strong pin thesis. The butterfly's variance is higher, which means deeper drawdowns and larger swings in equity.
When should I use an iron butterfly instead of an iron condor?
Use the iron butterfly when you have high conviction the stock will pin near the short strikes — for example, after a vol-crushing event like earnings, or on names with heavy gamma exposure that anchors the price. Use the iron condor when you just want the stock to stay in a wide range without a specific pin target.
What's a broken-wing butterfly?
A broken-wing butterfly is a variation where one wing is wider than the other, biasing the trade against a specific direction. It's often opened for a small credit or zero cost, eliminating the max loss on one side entirely. It's a hybrid between the butterfly's high payoff and the condor's directional flexibility.
Do iron butterflies have better capital efficiency than iron condors?
Yes — for the same wing width, the butterfly's max loss (and therefore its margin requirement) is typically 40-60% smaller than the condor's, because the credit collected reduces the worst-case loss more aggressively. Per dollar of locked capital, you can size roughly 2x the butterfly contracts vs condor contracts.
