What is CPM?
CPM is the cost of 1,000 ad impressions. Use the same campaign, currency, and impression definition for the values you compare.
$1,200 spent on 150,000 impressions gives a CPM of $8.
When do two media quotes cost the same?
An $8 CPM quote and a $5 CPM quote with a $300 fixed fee both cost $800 at 100,000 impressions. Above that volume, the $5 CPM quote costs less.
