Month over Month (MoM) is a term used to compare the performance of a metric or business metric from one month to the same month in the previous year.
For example, a company may compare its sales from December 2021 to its sales from December 2020 to see if its sales have increased or decreased over the last year. This type of comparison is useful for tracking the overall health of a business and identifying trends over time. It is often used in conjunction with other metrics, such as year over year (YoY) growth, to provide a more complete picture of a company's performance.
