Month on month (MOM)
Month on month (or MoM) is an expression used to compare data from one month to the previous month. For instance, if you were to say, ‘In August company X had a MoM revenue growth of 3%’, this would mean that August’s revenue exceeded July’s by 3%.
How to calculate month-on-month growth
Month-on-month growth is calculated by subtracting the first month’s figure from the second month’s figure in a sequence and dividing the resulting figure by the first month’s figure. To get a percentage – your month-on-month growth rate – simply multiply the result by 100.
