Month over month (MoM) growth is a metric that measures the percentage change in a value from one month to the next. It's one of the most common ways to track short-term business performance and identify trends.
The formula is: MoM Growth = ((Current Month - Previous Month) / Previous Month) × 100

Frequently Asked Questions
- What is a good month over month growth rate?
- A 'good' MoM growth rate varies by industry and company stage. For startups, 10-20% MoM growth is often considered strong. For established businesses, 2-5% MoM growth may be excellent. Context matters more than absolute numbers.
- How do I account for seasonality in MoM analysis?
- Seasonality can significantly impact MoM comparisons. Consider using year-over-year (YoY) comparisons for seasonal businesses, or compare to the same month in previous years while also tracking MoM for short-term trends.
- Can MoM growth be negative?
- Yes, negative MoM growth indicates a decline from the previous month. This isn't always bad—it could be seasonal, or follow an unusually strong previous month. Always analyze the context.
- How is MoM different from CMGR (Compound Monthly Growth Rate)?
- MoM measures change between two specific months, while CMGR calculates the average monthly growth rate over a longer period. CMGR smooths out volatility and is useful for understanding overall growth trajectory.
