How to show data divided by future months

Hello amitchandak , thanks for stopping by. 

Well, I followed the post you provided but i sadly doesn't meet what I need, or I didn't manage to get it properly working. 

So after I adapted your formulas I end up getting this result:

And the data I have is this:

As you can see, I need to show a visual with Month/Year (your first example) but with the amount paid divided by the duration of the stay. 
As an example:
1. First line shows €1.941,00 paid in 11/2021 that's valid until the beggining of 12/2021 (this amount goes into the 11/2021 pot);

2. The second line likewise;

3. Third line, €2.835,40 paid in 12/2021 that's valid until the beggining of 01/2022 (this amount goes into the 12/2021 pot) 

4. And so on.

5. The problem is the 5th line: someone paid 600€ for 12 months, starting in 01/2022 and ending at the beggining of 01/2023. 

I need to show 50€ (=600/12) every month since it was paid (50€ in 01/2022, 50€ in 02/2022, etc.).

Maybe i'm missing something? 
(I deleted the relationship between the DATE table and the FACT table since it messed the crossjoin DAX you so kindly provided.)

Thanks!
