How to Make a CPM in Excel: Step-by-Step Guide

Making a CPM, or cost per thousand impressions, calculation in Excel is a straightforward process. It involves using a simple formula to determine how much it costs for your advertisement to be seen 1,000 times. By the end of this article, you’ll know how to set up your Excel spreadsheet to automatically calculate CPM for all your advertising campaigns.

Step by Step Tutorial: How to Make a CPM in Excel

Before we dive into the steps, it’s worth noting that CPM is a commonly used metric in advertising to measure the cost-effectiveness of a campaign. It’s calculated by dividing the total cost of the advertising by the number of impressions, then multiplying by 1,000.

Step 1: Open Excel and Set Up Your Spreadsheet

Open Excel and set up a new spreadsheet with columns for your advertisement costs and impression counts.

Creating separate columns for each variable will help keep your data organized. Label one column as ‘Ad Costs’ and another as ‘Impressions’. This will allow you to input your advertising spend and the number of impressions each campaign receives.

Step 2: Enter Your Data

Input your advertisement costs and impressions data into the respective columns.

Make sure to enter each piece of data in the right column. This will ensure accuracy when Excel calculates the CPM.

Step 3: Use the CPM Formula

In a new column, input the CPM formula: =(Cost/Impressions)*1000.

This formula takes the total cost and divides it by the number of impressions. Then, it multiplies the result by 1,000 to calculate the cost per thousand impressions.

Step 4: Drag the Formula Downward

Drag the CPM formula down the column to calculate CPM for all your data entries.

Click on the cell with the formula, and a small square will appear in the bottom right corner. Click and drag this square down the column to apply the formula to all data entries.

Step 5: Format the CPM Column

Format the CPM column as currency to make the data easier to read and understand.

Right-click on the top cell in the CPM column and select ‘Format Cells.’ Then, choose ‘Currency’ to format all the CPM calculations as monetary values.

Once you’ve completed these steps, your Excel spreadsheet will automatically calculate the CPM for each of your advertising campaigns. This will enable you to quickly and efficiently assess the cost-effectiveness of your marketing efforts.
