Options trading offers many advanced strategies to limit risk and maximize returns. One of the most popular among intermediate and advanced traders is the Butterfly Spread.
It is a smart combination of buying and selling options at different strike prices to create a defined risk and reward opportunity.
If you are trading Butterfly Spreads, calculating potential profit quickly is essential. That’s where our Butterfly Spread Profit Calculator comes in!
With just a few simple inputs, you can instantly see your maximum potential profit per contract.
In this guide, we will explain what a Butterfly Spread is, how to use the calculator, the formula it uses, example calculations, and much more to help you trade smarter.
What Is a Butterfly Spread?
A Butterfly Spread is an options trading strategy designed to have limited risk and limited profit potential.
It is typically used when a trader expects the underlying asset to stay near a specific price at expiration.
It involves:
- Buying one lower strike call (or put)
- Selling two middle strike calls (or puts)
- Buying one higher strike call (or put)
The goal is for the stock price to end up exactly at the middle strike price at expiration.
At that point, the strategy earns its maximum profit.
How to Use the Butterfly Spread Profit Calculator
Using the calculator is easy and fast. Here’s how you can do it step-by-step:
- Enter the High Strike Price ($)
Input the highest strike price from your butterfly spread setup. - Enter the Low Strike Price ($)
Input the lowest strike price from your butterfly spread. - Enter the Average Premium ($)
This is the total net cost (debit) or net credit of your entire butterfly spread divided by the number of contracts. - Click on “Calculate”
The calculator will instantly display your Maximum Profit per Contract.
This tool is designed for option spreads where you want to measure maximum potential profit without manually calculating it every time.
Formula Used in the Butterfly Spread Profit Calculator
The formula used is simple and straightforward:
Maximum Profit = High Strike Price – Low Strike Price – Average Premium
In plain words:
- You take the difference between the high and low strike prices.
- Then, subtract the cost (average premium) you paid for the spread.
This result tells you the most profit you can make per options contract if the underlying asset finishes at the ideal price.
Example Calculation
Let’s walk through an example:
Suppose you have the following butterfly spread setup:
- High Strike Price = $110
- Low Strike Price = $90
- Average Premium Paid = $15
Using the formula:
Maximum Profit = High Strike Price – Low Strike Price – Average Premium
Maximum Profit = 110 – 90 – 15
Maximum Profit = 5
So, the maximum profit per contract is $5.
Since 1 options contract typically represents 100 shares, your total maximum profit would be:
5 × 100 = $500
Why Use a Butterfly Spread?
Butterfly Spreads are popular for several reasons:
- Defined Risk: You always know the maximum amount you can lose.
- Defined Reward: You know exactly how much you can make.
- Low Cost: Setting up a Butterfly Spread often costs less compared to other strategies.
- Profit from Stability: Perfect for when you think the stock will stay near a certain price.
Additional Helpful Information

The breakeven prices are slightly above the lower strike plus the premium paid and slightly below the higher strike minus the premium paid. - Maximum Loss:
Your maximum loss is limited to the premium paid for the Butterfly Spread. - Risk-to-Reward Ratio:
The Butterfly Spread offers an attractive ratio because the potential loss is small compared to potential gains. - Ideal Conditions:
