Calculate the cost of extra reach
Find out what you paid to reach people beyond your existing plan.
Compare matched reach counts
Suppose a plan reaches 40,000 people for $800 and an expanded plan reaches 55,000 for $1,250. The expansion costs $450 for 15,000 additional people, or $30 per thousand additional people reached.
Check the units
Reach counts unique people within the reporting system. Impressions include repeated exposure. The cost of extra reach can rise even while CPM is stable, because more impressions go to people already exposed.
Decide whether the expansion fits
Inspect which audience the additional reach represents and how much frequency also changed. Deduplicating across platforms may be impossible with the available data, so label the scope of the estimate.
