Method & formula
Viewability divides viewable impressions by served impressions. The optional monetary figure is a simple eCPM-equivalent value for the non-viewable portion, not a guaranteed recoverable amount.
- Viewability % = viewable impressions / served impressions x 100
Example
70,000 viewable impressions from 100,000 served impressions gives 70% viewability.
FAQ
Is this a forecast?
No. It is deterministic planning arithmetic based on the assumptions you enter. Actual commercial performance can differ.
Can viewable impressions exceed served impressions?
No. The calculator rejects that input because viewable impressions are a subset of served impressions.
