How to rename a formula

Hi all,

I thought this might be simple, but it seems to be more difficult than it sounds.

If I have 2 formulas in the one cell. Example:
=sum(A1:A5)*IF(A1>0,A1*B1,0)

Is there a way to rename each formula as such:
=TOTAL*VARIABLE

Where;
TOTAL=sum(A1:A5)
and
VARIABLE=IF(A1>0,A1*B1,0)


BUT... The tricky part is, I don't want the renamed formulas to be absolute. I.e. If I drag the formula down, I would like the cell referencing to drag down also.


I have attached an example for reference.

Thanks in advance.
