Tableau Running Total Calculation

In this article, we will show you how to calculate the Tableau Running Total with an example. For Tableau Running Total demo, we are going to use the Data Source we created in our previous article.

Please visit Data Labels in Tableau Reports article to understand the Tableau Data Source.

Calculate Tableau Running Total

Before we start calculating the running total in Tableau, let me create a tableau report that we are going to use in this example. First, Drag and Drop the order date (Year) from Dimension Region to Column Shelf.

Next, Drag and Drop the Order date (Quarter), and Order date (Month) from Dimension Region to Rows Shelf. Finally, Drag and Drop the Sales Amount from measures region to text filed present in the Marks shelf. Once you drag them, the following Table Report will generate.

As you can see, we don’t have much data (sales) for the years 2010 and 2014. So, we are excluding those two years from the table report by selecting those two columns, and then clicking the exclude button present in the tooltip

The below screenshot will show you the final report that we are going to use for calculating the running sum in Tableau.

To calculate the running Total in Tableau, we have to add the table calculation. To do so, click Down arrow beside the Sales Amount measure (change as per requirement) will open the context menu.

From the list of available options, either you can select the Add Table Calculation option or Quick Table Calculation option. I suggest you use the Add Table Calculation option

Once you click on the Add Table Calculation option, a new window called Table Calculation will open, as we have shown below. As you can see, by default, Tableau has selected the Calculation Type as Difference from, and Compute using option as Table (across).

Please change the calculation type from Difference From option to Running Total

I think it will be helpful to show the Sales Amount values. So that you can compare the Running Total with the Original Sales Amount values, let us add the Sales Amount to Columns Shelf.

As you can see, Tableau shows the Original values and its running Total for each year.

Tableau Running Total for each Partition

It will be nice if we calculate the Running Total for each partition or each Quarter. To change the actual calculation, we have to edit it.

To edit the existing table calculation, please click on the down arrow beside the table calculation will open the context menu. Here you have to select the Edit Table Calculation option, as shown below.

Once you click on the Edit Table Calculation option, a new window called Table Calculation will open. As you can see, tableau has selected the best possible options such as Calculation Type as Running Total, Aggregation as SUM, and Compute using option as Specified Dimensions (Quarter of Order date, and Month of Order Date) by default.

Here, you have to change the Restarting Every option from None to Quarter of Order date. It will ensure tableau to restart the running total for every quarter of the year.

Now you can see the running total for each quarter

Add Secondary Calculation in Tableau

Tableau allows us to add the secondary calculation to the report. It is beneficial to calculate further on top of the actual calculation. To do so, Please check the Add Secondary Calculation option, as shown below.
