Month number up to 36 months

[v_mark]

Hi,

 I do have a date table that has Month number 1 -12. I'll be needing to have a Month number that is up to 36 months

from there I will calculate the running total. My problem is I don't know how to extend those Month numbers up to 36.

Is there a way to extend the month number perhaps adding an additional column in my date table? 

Expected results below

Month Number	2020
1	$     20,596.06
2	$     45,126.28
3	$     91,347.39
4	$   174,197.00
5	$   226,621.92
6	$   298,256.10
7	$   422,952.74
8	$   553,579.03
9	$   734,440.15
10	$   937,718.69
11	$1,105,015.87
12	$1,226,298.16
13	$1,375,038.69
14	$1,546,216.62
15	$1,753,902.65

@v_mark , after 12 months data is repeating, what is the advantage of 36 months

I updated the view above.  I just realize that just the number of months will do and yes my bad the example above is just used as a representation.

pretty much a running total for 36 months that has an indicator on the left side 1-36
