## How to calculate butterfly spread profit?

Example Problem:

The following example outlines how to calculate the maximum profit of a long butterfly spread.

First, determine the lowest strike price. In this example, the low strike price is $5.00. Next, determine the higher strike price. The highest strike price in this spread is$12.50.

Next, determine the average premium paid. The average premium for this problem is $2.00. Finally, calculate the maximum profit per contract using the formula above: MP = HS – LS – P MP = 12.50 – 5.00 – 2.00 MP =$5.50.00
