Just gimme the code! Here’s an example of a percent of the total group/pivot:
And here’s the SQL used in the table calculation: 
${orders.total_order_amount} /
  SUM(${orders.total_order_amount}) OVER (
    PARTITION BY
      ${orders.status}
  )
In general, the SQL used for calculating the percent of the total has two important columns:
  • column_i_want_to_see_the_percent_of_total - this is the column that you want to see the percent total of. In our example above, that was the sum of profit.
  • column_i_want_to_group_by - this is the column that you want the total to be grouped by. In our example above, that was the order date - week.

​
Here’s the SQL you can copy-paste to calculate the percent of the group/pivot total

${table.column_i_want_to_see_the_percent_of_total} /
  SUM(${table.column_i_want_to_see_the_percent_of_total}) OVER (
    PARTITION BY
      ${table.column_i_want_to_group_by}
  )

Make sure to add percent formatting to your calculation

In the format tab, make sure to update the format to percent so that your table calculation is shown as a percentage value (instead of a number).
