## Excel Formula to PowerBI

Hi, I am new here...

I have this formula in Excel +P12/N12-1, and now I am trying to use it en PowerBI desktop and it doesn't work.

My calculated formula in PowerBI  is> Base = DIVIDE(sum([R15-16]),sum([R14-15]),0) and I need to add the -1

Hope you can help me!

I may be mixing up blank/zero parsing... Try

```Base = IF(
ISBLANK(SUM([R14-15])),
BLANK(),
DIVIDE(
SUM([R15-16]),
SUM([R14-15]),
0
) - 1
)```

Have you tried literally just adding the -1 to the formula?

Sure, but then I lost the group and

Base = DIVIDE(sum([R15-16]),sum([R14-15]),0) - 1

When I do it in this way, the group is totally lost and I get my result and the other data from another rows...

All those rows that show -100% have blank values in R14-15 and R15-16, so DIVIDE returns zero. Zero minus one is negative one. Negative one is negative one hundred percent. So those results are correct for the formula you wanted to replicate. That's what your excel formula would return given the same data. If you'd like those rows to return 0 instead of -1, you could do something like

```Base = IF(
SUM([R14-15]) = 0,
0,
DIVIDE(
SUM([R15-16]),
SUM([R14-15]),
0
) - 1
)```

The same result that Base = DIVIDE(sum([R15-16]),sum([R14-15]),0) - 1  Community Champion
