At a glance: Find out how ROAS is calculated in Cost Center to analyse your campaigns better.
Background
Cost Center calculates ROAS Dx only when there is enough revenue data. I.e ROAS D3 is only calculated for days less than current date - 4.
ROAS Dx = LTV Dx / eCPI
How to troubleshoot
Expand the report to date level to find out which days have enough data for Dx.
If you’re more familiar with the way that MMPs calculate, you can change the setting to always calculate ROAS Dx even when there is not enough data.
Go to App Settings > Advanced > Revenue Metric Data Availability > Latest
Note that Cost Center's Bid Automation will consistently employ the "Completed" revenue calculation to ensure reliable metrics without missing data even after adjusting settings
You can also select the report date range (i.e. From Date - To Date) to an earlier date to ensure sufficient data for the Dx you're examining across all days.
