Estimated earnings
Your account balance for the time period selected. This amount is an estimate that is subject to change when your earnings are verified for accuracy at the end of every month.
How custom events are factored into estimated earnings
Estimated earnings include earnings from custom events using the manual eCPM value entered during setup.
AdMob will estimate custom event earnings using the following formula:
Custom event 1 est. earnings= (Manual eCPM for custom event 1 * Number of impressions for custom event 1) / 1000
How estimated earnings is reported in your Mediation report
AdMob estimates earnings proportionally based on the number of impressions each ad unit receives. This change eliminates double counting revenue when ad unit mapping is reused across multiple ad units.
AdMob will estimate your optimized third-party revenue for each ad unit using the following formula:
Ad unit 1 est. earnings= Earnings reported by optimized third party ad network / (Total number of impressions for all ad units that use the same mapping information) * Number of impressions for Ad unit 1
Example calculation of estimated earnings
Ad unit 1 has $200 while ad unit 2 has $1800 of earnings. It's calculated by:
| Ad unit | Impressions | Estimated earnings (new) |
| Ad unit 1 | 100 | $200= ($2000/(100 +900) * 100) |
| Ad unit 2 | 900 | $1800= ($2000/(100 + 900) * 900) |
| Total | 1000 | $2000 |
