# Percentage Metrics

### OVERVIEW

Percentage metrics in Pluto Insights are metrics that represent a value as a percentage of a total or a subset of the data. They are useful for comparing proportions or relative contributions of different categories within your dataset. ### HOW TO CALCULATE PERCENTAGE METRICS

To calculate percentage metrics, you typically combine an aggregate function with a specific column or set of columns that define the denominator or subset of the data.

Here are a couple of examples:

> Percentage of Total: This metric calculates the percentage of a value in relation to the total. For instance, you might want to visualize the percentage of total enrollments contributed by each course category. To do this, select the "Sum" aggregate function for the enrollments column and divide it by the total enrollments across all categories. The resulting percentage metric will show the relative contribution of each course category to the overall enrollments.

> Percentage of Subgroup: This metric calculates the percentage of a value within a specific subgroup or category. For example, you may want to compare the percentage of learners who completed courses within different companies. To do this, use the "Count" aggregate function to count the number of learners within each company and divide it by the total number of learners. The resulting percentage metric will show the proportion of learners in each company. Percentage metrics help you gain insights into the relative distribution or contribution of different categories or subsets of your data. By visualizing these percentages in charts, you can effectively compare and analyze proportions across various dimensions.
