Alteryx rounding

Hi All, 

I have a calculation in my tool that is currently calculated in Alteryx, while I was reviewing the data I found that when I re-calculate the number is excel it is different from the Alteryx calculation . Although they are close they do not match. Please find below the details on the calculations- I tried every possible way to tweak both Alteryx and excel and I am not able to match them. 

Data:

Formula:

Step 1: ROUND(X3/(1-X4),5)

Step 2:  ( Step 1 ) * ( X1 *X2 )

Thanks
