Month-over-month (MoM) growth shows the change in the value of a specific metric as a percentage of the previous month's value. Month-over-month growth is often used to measure the growth rate of monthly attributes such as sales, profit, etc.
It can be calculated as
(SUM([Measure]) - LOOKUP(SUM([Measure]), -1)) / (LOOKUP(SUM([Measure]), -1))
where measure is sales/ profot, etc.
Hope it helps!
