Enter the total margin ($) and the exposure margin ($) into the SPAN Margin Calculator. The calculator will evaluate and display the SPAN Margin.

SPAN Margin Formula

The following formula is used to calculate the SPAN Margin.

SPM = TM – EM

• Where SPM is the SPAN Margin ($) • TM is the total margin ($)
• EM is the exposure margin ($) How to Calculate SPAN Margin? The following example problems outline how to calculate SPAN Margin. Example Problem #1: 1. First, determine the total margin ($).
• The total margin ($) is given as: 167. 2. Next, determine the exposure margin ($).
• The exposure margin ($) is provided as: 40. 3. Finally, calculate the SPAN Margin using the equation above: SPM = TM – EM The values given above are inserted into the equation below and the solution is calculated: SPM = 167 – 40 = 127.00 ($)

Example Problem #2:

For this problem, the variables required are provided below:

total margin ($) = 780 exposure margin ($) = 200
