Put Christmas Tree Butterfly Calculator

By Yojana Mandon · Updated June 2026 · 2 min read · Risk disclaimer

A put christmas tree butterfly is a skewed, budget butterfly: long one put near the money, short three puts a couple of strikes lower, and long two puts one strike lower still. The uneven quantities create a cheaper, bearish-leaning tent whose profit zone sits below the current price. It is the put-side twin of the call christmas tree butterfly, with defined risk.

Key characteristics

When to use a put christmas tree butterfly

Use a put christmas tree butterfly when you lean mildly bearish and want a cheaper alternative to a standard butterfly, with the profit zone positioned below spot. The unequal legs lower the cost and shift the payoff toward a modest decline.

It is an efficient way to target a downside drift into a specific area without paying full butterfly price. The balanced quantities (one long, three short, two long) keep the total contracts matched so the risk stays defined.

Risks and management

The trade profits if the stock eases into the zone around the short strikes and loses its (limited) cost if the stock moves too far in either direction. Because the structure is skewed, the payoff is asymmetric — read the exact breakevens and peak off the chart.

Manage it by aligning the short strikes with your downside target, taking profits as the stock settles into the zone, and remembering the maximum value is realised at expiration. Keep size aligned to the defined maximum loss.

On the Greeks, the Put Christmas Tree Butterfly is vega-negative — a fall in implied volatility (such as an earnings IV crush) works in your favour, and theta-positive, so time decay adds to the position each day it is held.

Worked example. A stock trades at $100. You buy the $100 put, sell three $98 puts, and buy two $97 puts for a small net debit. If the stock eases toward $98 into expiration the trade reaches its peak value; a move well above $100 or well below the lower strikes leaves only the small defined loss.

Frequently asked questions

Why the unequal number of contracts?

The 1–3–2 structure (long, short, long) keeps the net quantity balanced while skewing the strikes, which lowers the cost and shifts the profit zone below spot.

Is the risk defined?

Yes. The long puts cover the three short puts, so the maximum loss is limited and known when you open the trade.

How does it differ from a standard put butterfly?

A standard butterfly is symmetric (1–2–1). The christmas tree uses uneven strikes and quantities to cut the cost and lean the payoff in one direction.
