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

Future Margin Formula

The following formula is used to calculate the Future Margin. 

FM = SM + EM
  • Where FM is the Future Margin ($)
  • SM is the SPAN margin ($) 
  • EM is the exposure margin ($) 

To calculate the future margin, sum the SPAN margin and the exposure margin together.

How to Calculate Future Margin?

The following example problems outline how to calculate Future Margin.

Example Problem #1:

  1. First, determine the SPAN margin ($).
    • The SPAN margin ($) is given as: 125.
  2. Next, determine the exposure margin ($).
    • The exposure margin ($) is provided as: 75.
  3. Finally, calculate the Future Margin using the equation above: 

FM = SM + EM

The values given above are inserted into the equation below and the solution is calculated:

FM = 125 + 75 = 200.00 ($)


Example Problem #2: 

For this problem, the variables required are provided below:

SPAN margin ($) = 160

exposure margin ($) = 80

Test your knowledge using the equation and check your answer with the calculator above.

FM = SM + EM = ?
