The CPM model refers to advertising bought on the basis of impression. This is in contrast to the various types of pay-for-performance advertising, whereby payment is only triggered by a mutually agreed upon activity (i.e. click-through, registration, sale).

The total price paid in a CPM deal is calculated by multiplying the CPM rate by the number of CPM units. For example, one million impressions at $10 CPM equals a $10, 000 total price.

1, 000, 000 / 1, 000 impressions = 1, 000 units
1, 000 units $10 CPM = $10, 000 total price

The amount paid per impression is calculated by dividing the CPM by 1000. For example, a $10 CPM equals $.01 per impression.

$10 CPM / 1000 impressions = $.01 per impression
