If you've ever wondered how your business is really performing, month over month (MoM) analysis can be a powerful tool. But what exactly is it, and why should you care? Keep reading to find out!

What is month over month (mom)?

In layman's terms, month over month (MoM) is a calculation that shows the change in a specific metric from one month to the next. It's a simple yet effective way to track growth, identify trends, and understand the short-term performance of your business. Think of it as a quick snapshot of your progress.

Why is month over month important?

MoM analysis is important because it provides a granular view of your business performance. Unlike quarterly or annual reports, MoM allows you to:

  1. Identify trends quickly: Spot emerging patterns and react proactively. Are sales consistently increasing? Is website traffic declining? MoM helps you see it early.
  2. Pinpoint problems: If a metric suddenly drops, MoM can help you identify the exact month the issue began, making it easier to investigate the cause.
  3. Measure the impact of changes: Did you launch a new marketing campaign? MoM can show you its immediate effect on key metrics.
  4. Set realistic goals: By understanding your typical MoM growth rate, you can set more achievable targets for the future.
  5. Make informed decisions: Armed with MoM data, you can make data-driven decisions about resource allocation, marketing strategies, and product development.

How do you calculate month over month?

Here's the formula:

MoM Growth=Current Month Value−Previous Month ValuePrevious Month Value×100%\text{MoM Growth} = \frac{\text{Current Month Value} - \text{Previous Month Value}}{\text{Previous Month Value}} \times 100\%

This is how you calculate it step-by-step:

  1. Gather your data: Collect the data for the metric you want to analyze (e.g., sales, website traffic, revenue) for the current month and the previous month.
  2. Subtract: Subtract the previous month's value from the current month's value. This gives you the difference between the two months.
  3. Divide: Divide the difference by the previous month's value. This gives you the proportional change.
  4. Multiply: Multiply the result by 100 to express the change as a percentage.

Month over month example

Let's say your website traffic was 10,000 visits in January and 12,000 visits in February. Here's how you'd calculate the MoM growth:

  1. Data:
    • Current Month (February): 12,000
    • Previous Month (January): 10,000
  2. Subtract: 12,000 - 10,000 = 2,000
  3. Divide: 2,000 / 10,000 = 0.2
  4. Multiply: 0.2 * 100 = 20%

Therefore, your website traffic grew by 20% from January to February.

Practical applications of month over month

MoM analysis can be applied to a wide range of metrics. Here are a few examples:

  • Sales: Track MoM sales growth to understand how your sales performance is trending.
  • Revenue: Monitor MoM revenue growth to assess the overall financial health of your business.
  • Website traffic: Analyze MoM website traffic to see if your marketing efforts are driving more visitors to your site.
  • Customer acquisition: Track MoM customer acquisition to measure the effectiveness of your customer acquisition strategies.
  • Conversion rates: Monitor MoM conversion rates to identify areas where you can improve your sales funnel.

Common pitfalls to avoid

While MoM is a valuable tool, it's important to be aware of its limitations:

  • Seasonality: MoM can be misleading if your business is highly seasonal. For example, a drop in sales from December to January is expected for many retailers. In these cases, year-over-year (YoY) analysis might be more appropriate.
  • Short-term fluctuations: MoM can be influenced by short-term events, such as a viral marketing campaign or a major product launch. Don't overreact to a single month's data. Look for long-term trends.
  • Small sample sizes: If you're working with small numbers, MoM changes can be exaggerated. For example, an increase from 1 to 2 customers represents a 100% MoM growth, but it's not necessarily significant.

Tools for calculating month over month

Luckily, you don't have to do all the calculations manually. Many tools can help you track and analyze MoM data, including:

  • Spreadsheet software: Programs like Microsoft Excel and Google Sheets have built-in formulas for calculating MoM growth.
  • Business intelligence (bi) dashboards: Tools like Tableau and Power BI can automatically track and visualize MoM data.
  • Analytics platforms: Platforms like Google Analytics can track website traffic and other metrics on a MoM basis.

Month over month vs. year over year: what's the difference?

It's interesting how MoM compares to Year-over-Year (YoY) analysis. While MoM looks at changes from one month to the next, YoY compares a month to the same month in the previous year. YoY is particularly useful for understanding long-term trends and mitigating the impact of seasonality. Think of MoM as a magnifying glass for short-term trends, and YoY as a wide-angle lens for long-term performance.

Conclusion

MoM analysis is a valuable tool for understanding the short-term performance of your business. By tracking MoM growth, you can identify trends, pinpoint problems, measure the impact of changes, and make informed decisions. Naturally, we encourage you to incorporate MoM analysis into your regular business reporting to gain a deeper understanding of your performance. Remember to consider the limitations of MoM and use it in conjunction with other metrics, such as YoY, for a more complete picture.
