# How to Calculate Cost Per Mille (CPM): 7 Steps

Cost per thousand (CPM) is an advertising indicator that represents the cost of one thousand ad impressions. An impression is basically the display of the advertisement by a potential customer. CPM is calculated by taking the cost of an ad, dividing it by the number of real impressions and finally multiplying it by 1000 (CPM = Cost / Impressions x 1000). Most of the time, this value is indicated by the platform providing the ad space and is used to calculate the total cost of an advertising campaign.

## Steps

### Method 1 of 2: Calculate the CPM

#### Step 1. Determine the budget available for the advertising campaign

Typically, a marketing action is planned to present an idea or product to the public; if you decide to invest 10,000 euros in advertising, you have half the data you need to calculate the CPM.

#### Step 2. Determine the total number of impressions

In order to calculate the cost of a thousand of them, you need to know how many you want to publish (you quantify the audience that is reached by the ad).

• For example, the company wants to plan a campaign with 500,000 impressions.
• IT tools such as Google Analytics are useful for determining the traffic of a website; television and the press typically use sales or audience statistics for this data.

#### Step 3. Do the calculations

The cost of the campaign must be divided by the number of impressions and multiplied by 1000; consequently (10,000 / 500,000) x 1000 = 20.

### Method 2 of 2: Leveraging the Concept

#### Step 1. Calculate the potential cost of an ad campaign

CPM is often set by the platform that sells the ad space; however, you can use the formula to understand what is the cost you have to incur for a certain number of views.

• Total Cost = (Total Impressions x CPM) / 1000.
• For example, for 1,000,000 views with a CPM of 50 (i.e. \$ 50 per 1000 impressions) the company would spend \$ 50,000.

#### Step 2. Calculate the potential audience you can reach within your budget

By leveraging the formulas in the same way, if you have established ad campaign funds and CPM, you can know how many people will potentially see your ad.

• Potential Audience = (Total Cost x 1000) / CPM.
• For example, a budget of \$ 50,000 for a campaign with a CPM of 10 achieves 5,000,000 impressions.

#### Step 3. Sell the space

If you have a website and want to make money from advertising, CPM is calculated based on page traffic and the amount of money the advertiser is willing to spend to reach your audience.

### When it comes to online advertising this calculation is often performed automatically using services such as Google Analytics; the value of your space is calculated and sold to those who bet on it

#### Step 4. Maximize the cost / benefit ratio

CPM rates are useful for companies and advertisers to present their products to a wider audience at a more reasonable cost. This is a very variable indicator that can be used to compare the costs of the spaces of different platforms.
