Calculating CPM is a very easy division and multiplication mathematics and very easy to calculate. It is calculated by simply taking the total cost of the advertising campaign and dividing it by the total number of impressions, and then multiplying the number by 1000 (CPM = cost/impressions x 1000).

#### Doing the maths using the above figures

Let’s assume a given company is planning to spend $10,000 for a CPM campaign and wish to get about 400,000 impressions.

To determine the cost they are going to pay per 1,000 impressions, you have to take the $10,000 and divide it by 400,000 which is the desired impressions, and then multiply it by 1,000 to get the cost per 1,000 impressions which is $25 in our case.
