Custom metrics

1. 1Open Settings, then Markup and metrics.
2. 2Under Add a custom metric, type a name, for example Cost per lead incl. fee.
3. 3Pick Show as (Number, Money or Percent) and the number of decimals (0 to 4).
4. 4Type the formula, for example spend / leads. Lumina checks it as you type.
5. 5Tick Lower is better if the metric is a cost, so a drop shows in green.
6. 6Click Add metric.

Custom metrics show in report number tiles, charts, tables and the chart metric filter, and in PowerPoint and Excel downloads.

• A formula uses numbers, + - * / and brackets, and these names: spend, impressions, clicks, link_clicks, conversions, revenue, reach, leads, installs, engagements and video_views. It must use at least one name, and can be up to 300 characters.
• Percent shows the result times 100, so clicks / impressions reads like a CTR.
• Each formula is worked out from the totals for a row, a day or the period, so it is never an average of averages.
• Dividing by zero, or a number the platform does not report, shows as empty, not 0.
• Formulas with spend include the client's markup where the client sees markup.
• Clients see the metric's name and value, not its formula.
• A workspace can have up to 50 custom metrics. Only owners and admins can add, edit or delete them. Deleting one removes it from the reports that show it.
