What Is Cost per Mille (CPM) In Digital Marketing?

“Cost Per Mille” or CPM, is a phrase that is commonly used in the field of digital marketing. However, what does it really mean, and why is understanding it crucial for marketers? Let’s explore this digital environment and solve the CPM mystery.

What is CPM or Cost Per Mille?

Cost per thousand impressions, or CPM, is a number that advertisers use to calculate the cost of reaching 1,000 potential customers with their advertisement. The essence of this metric is reflected in the fact that the term “Mille” in CPM really means “thousand” in Latin.

How is CPM Calculated?

Calculating CPM is quite straightforward. It’s determined by dividing the total cost of the advertisement campaign by the number of impressions (views) the ad receives, then multiplying by 1000. Mathematically, it can be represented as:

CPM= Cost/Impressions ×1000

Let’s examine it in more detail using this example:

Suppose you run a digital ad campaign that costs $500 and receives 100,000impressions. To calculate the CPM:

CPM = \frac{500}{100,000} \times 1000 = $5

So, in this scenario, the CPM would be $5.
