How Cumulative Average Can Figure Out Your Sale in Power BI?


The cumulative average is a metric that measures the average value of sales over a specific period. As such, it is an important tool for understanding patterns in customer behavior. However, in some cases, cumulative averages can be misleading or inaccurate. One way to determine if the average is giving you the right answer for your data set is with the cumulate-a-function analysis function in Power BI.


This function will help you build cumulative averages that are more accurate and useful than those from standard analysis tools like mean and median functions. We at Enterprise DNA offer various Power BI courses covering all aspects of the platform that are suitable for all levels of users, from beginners to advanced.


Firstly, you need to know how the cumulative average works. Unlike the mean and median functions, which use a single value to calculate the average of your data, a cumulative average takes all values up until that point into account when calculating the final figure.


Why is the Cumulative Average More Convenient?

1. It is easier to compare to the previous period’s average:

With a cumulative average, it is easy to see where your data is coming from. If your sales are high in the first week of the quarter and then not so much for a few more weeks, you can easily spot it by comparing the cumulative average with the first week’s value.


2. It can help you find patterns in your data that might not be as obvious as a regular average.

Using the median and Average together, you can see a hidden trend in your data. The more weeks you add to the cumulative average, the more it will converge towards the median value. It signalizes a hidden pattern that might be more important than your sales figures look at first sight.


3. It is easier to compare to data from other companies or other data sets:

You can easily see where your value is coming from and make comparisons to the industry average. It makes it much easier to understand your performance compared to others and conclude that. Cumulative Averages let you see where your sales are coming from and can be used to figure out what is advantageous to improve.


4. It will help you see trends over time:

The cumulative average grows steadily towards the median, revealing that the trends are stable and long-term. It is also clear that the average does not have any particular bias and will accurately represent your data’s trend over time.


5. It can help you spot outliers more easily:

If there are any outliers in your data set, they will be easily visible to you with this function. The outliers will be able to influence the cumulative average figure significantly, and it will be very noticeable in your graph. The outliers will also influence your cumulative average, making it very easy to know where your data comes from.


6. It can help you identify the distribution of your data over some time:

The cumulative average will create a nice graph of where your values are in the data set and how they spread out over the periods presented. It can be used to identify whether there are more or fewer sales at certain points in time and whether those values contributed much to the overall average.


7. You can easily analyze the effect of your campaigns:

A cumulative average helps you see what is happening with your sales over time. In many cases, the analysis can indicate whether the campaign was an overall success. If your campaign has a negative contribution to the cumulative average, then there is a reason for concern, and it may need adjustments to make it more successful in the future.


8. It is a very useful tool for trend analysis:

If you want to analyze the trend in sales, you can use the cumulative distribution function (also called “quantile”) to limit your data set. The quantile software can show the cumulative distribution over time. It will give you a clean chart where the low and high quantiles are visible – in other words, the 10th, 50th, 80th etc., percentile values.



The cumulative average is a very useful metric that can be used in many different situations and allows you to analyze your data effectively. The cumulative average will let you see trends and patterns in your data that can help you make decisions or draw conclusions about your performance. It is also possible to use other functions such as mean, median, or quantile along with the cumulative average. You learn about Power BI from beginner to advanced courses at Enterprise DNA.
