Step by step
- 1List your months in one column and the metric (e.g. revenue, users) in the next.
- 2Leave the MoM Growth cell blank for the first month.
- 3In the second month row, enter =(B3-B2)/B2.
- 4Format as a percentage and copy the formula down for all subsequent months.
Tips
- For seasonal businesses, MoM growth can be misleading. Consider also calculating YoY growth for the same month to get a clearer signal.
- To calculate rolling 3-month average growth, average the last three MoM values: =AVERAGE(C3:C5).

Frequently asked
How do I handle months with zero values?
A zero prior month causes #DIV/0!. Use =IFERROR((B3-B2)/B2,"") to leave the cell blank when the prior value is zero.
Can I calculate MoM growth for multiple products at once?
Yes — structure your data with products as columns and months as rows, then apply the formula to each column independently.
