## How to calculate?

Formula: **CPM = (Cost / Impressions) * 1000**

**Explanation:**

**CPM:**This represents the cost you incur to reach 1,000 viewers with your ad. It's a standard metric used for comparing advertising costs across different platforms.**Cost:**This refers to the total budget you spend on your advertising campaign.**Impressions:**This signifies the total number of times your ad is displayed, regardless of clicks or interactions.**1000:**Since CPM represents cost per**thousand**impressions, we multiply by 1000 to ensure the result is in that unit.

**For example:**

- Let's say your campaign cost was $100 and you received 25,000 impressions.
- Using the formula: CPM = ($100 / 25,000) * 1000 = $4

**Interpretation:** In this example, your CPM is $4, meaning it cost you $4 to reach 1,000 viewers with your ad campaign.
