Why Calculate Percent of Total in Tableau?

Calculating the percent of total allows you to:

  • Compare performance: See how individual products, regions, or employees contribute to overall sales.
  • Identify trends: Spot changes in percentage contributions over time.
  • Highlight key areas: Focus on the most significant drivers of your business.

Methods to Calculate Percent of Total in Tableau

Tableau offers several ways to calculate percent of total, each with its own advantages:

  1. Quick Table Calculation

    The easiest method is using the built-in quick table calculation:

    1. Drag the measure (e.g., Sales) to the Columns or Rows shelf.
    2. Right-click on the measure.
    3. Select Quick Table Calculation > Percent of Total.

    This is a fast way to get a basic percentage, but it might require further customization.

  2. Level of Detail (LOD) Expressions

    LOD expressions offer more control and flexibility. Here's how to use a FIXED LOD:

    SUM([Sales]) / SUM({FIXED : SUM([Sales])})

    This formula calculates each subcategory's sales as a percentage of total sales, regardless of other dimensions in the view. The FIXED keyword means it calculates a value that is independent of the filters in your view unless they are context filters.

    Another useful LOD is EXCLUDE:

    SUM([Sales]) / SUM({EXCLUDE [Category] : SUM([Sales])})

    This computes the percentage of total sales excluding the 'Category' dimension.

  3. Calculated Fields with WINDOW_SUM

    You can achieve percent of total using window functions:

    SUM([Sales]) / WINDOW_SUM(SUM([Sales]))

    This method is similar to table calculations but provides more explicit control over the calculation scope.

Examples of Percent of Total Calculations

Let's say you have a dataset of regional sales data:

  • Region A: $50,000
  • Region B: $75,000
  • Region C: $25,000

The total sales are $150,000. Using the methods above, you can determine that:

  • Region A accounts for 33.33% of total sales.
  • Region B accounts for 50% of total sales.
  • Region C accounts for 16.67% of total sales.
