# CPM Calculator

This **CPM Calculator** helps you calculate important metrics to evaluate your online marketing campaign by calculating the CPM rate.

The formula for calculating CPM is: CPM = (Total Cost of Campaign / Total Number of Impressions) x 1,000

By following these steps, you can calculate the CPM of any advertising campaign.

- Identify the total cost of the advertising campaign: Start by determining the total cost of the advertising campaign, including all expenses such as creative development, ad placement, and any other related costs.
- Determine the total number of impressions: Next, determine the total number of ad impressions that the campaign generated. An impression is counted each time an ad is displayed on a website or app.
- Divide the total cost by the number of impressions: Divide the total cost of the campaign by the number of impressions it generated. This will give you the cost per impression.
- Multiply by 1,000: Finally, multiply the cost per impression by 1,000. This will give you the cost per thousand impressions (CPM).
