## Month over Month Price Change (with last available price)

Hi everyone, I have a unit price table as follows:

I need to calculate month to month price movements (%).

I have 3 main product groups with a few subgroups.

Column sections present last year months.

The main issue for me is that some products weren't sell in 2 consecutive months.

Another possible problem could be that in one month could be a few sales of the same item.
That means I need average unit price on particular month.

I tried with various posted solutions but nothing have been seem working for me.

Thank you in advance for help!

It looks like it's gonna work!

One question though, how to hide infinity value in first month?

Hi @pawelj795 ,

You could edit the DAX with an IF function.

```IF(a<>BLANK(),
('Table (2)'[value]-a)/a,BLANK())```

Turns out, its not working properly.

Maybe because I have various values for same month?
I mean in same month, one product could be sold for different prices -> that's why I want to calculate average price in every month

Hi @pawelj795 ,

You could use SUMMARIZECOLUMNS() function to create a table with average value per month( group by month ).

Ok, I tried that solution but how modify your previous functions (rank & value%) to work with this new table?

I mean it's working only when I had one distinct value per month.
I cant really solve how to get deeper and have grouped values by group also, which mean I would have 3 values per every month.

Hi @pawelj795 ,

You could ignore blank value with functions.

Here is my test file for your reference.
