I am trying to auto populate a cell with sum of users for last month:

Column A Column B
Month No of Users

I have managed to calculate, this weeks, last weeks and the last 30 days
total of users using a variation of:
=SUMIF(A1:A100, "="&TODAY()-7, B1:B100)

I want to be able to see the last calender month total. So today I would get
the total number of users for November.

I have tried adding the MONTH function but the SUMIF function does like all
the arguments needed to calculate the what last month was.

Any help would be appreciated.

try
=sumproduct((month(a1:a100)=11)*b1:b100)

Try

=SUMPRODUCT(--(MONTH(A1:A100)=MONTH(TODAY())-1),B1:B100)

You can do it easier by using sumproduct and MONTH but if you want to use
SUMIF you would need something like

=SUMIF(A1:A100, "="&DATE(YEAR(TODAY()),MONTH(TODAY())-1,1),
B1:B100)-SUMIF(A1:A100, ""&DATE(YEAR(TODAY()),MONTH(TODAY()),0), B1:B100)
