%Difference

I'm not sure why my brain is drawing a blank here, I feel really dumb.

 

I have two columns, "SOW EHR" and "Actual EHR." 

 

I also calculated a "Delta" column. 

 

I need to calculate the %Difference between SOW EHR and Actual EHR.  When I tried, I was getting 100% for an instance where the two values were the same which means I should have been getting 0%.

Yes! Thank you.

 

I am, however, getting a couple of AVGs that are showing as NaN, but I don't know why.  Any idea of where to start investigating?

Hmm, I would think that would generally indicate a divide by zero error. You can try:

 

% Difference = DIVIDE([Delta],[SOW EHR])

Generally, I do    (NewValue - OldValue) / OldValue

 

110 - 100 / 100 would be 10% growth.
