# How to Calculate CPM: The Ultimate Short Guide to Online Success‍

Let’s face it. The cost per mille (CPM) is one of the most misunderstood and overpriced aspects of online advertising. While it can be useful when you’re trying to determine how much money your ad should be spending, the end result is often misleading. With that being said, there is more to digital advertising than just looking at a company’s cost per thousand or how much a certain search term costs. You need to understand the different ways CPMs are calculated so that you can calculate yours more accurately and see if it’s worth it for your business. Let’s take a look at how CPM works and why you might want to change your current rate.

## What’s cpm?

CPM is a cost-per-click (CPC) model that was developed in the 1980s by the Glenbrook Research Corporation. By using different bidding strategies and keywords, you can create an ads copy that appears on high-quality websites that are optimized for search engines. The idea behind CPM is that you will pay a certain amount each time someone clicks on your ad. This number can be as low as cents or as high as you wish it to be. Depending on how often your ad is shown to the public, you are either earning a dollar or seeing a dollar back. Some businesses also use a sliding scale model that starts at CPM 0.25 cents and drops to CPM 1 cents.

## How to Calculate CPM

Before we get into the formula itself, let’s discuss what you might call the “how” of CPM. There are many different ways calculating CPM, but the most popular is the “linear model.” This method takes into account the total cost of acquisition (e.g., your ad spend) and the total amount of revenue generated (e.g., sales). Using this method, you can see that \$500 spent on a particular keyword will lead to \$500 worth of revenue.

## The best way to calculate your CPM

The best way to calculate your CPM is to use these formulas: Total cost of purchase: This includes all of your ad spend and any discounts or coupons that you may have applied to make the total cost of your campaign lower. Total revenue from all your keywords: This includes all sales from all of your keywords and the revenue generated from other keywords that appear next to your brand. CTR (click through rate): This is the percentage of people who click on your ad and are taken to your website.

## Conclusion

CPM is a great way to target your audience and create ads that people will actually click on. It’s calculated by multiplying your cost per thousand by your desired conversion rate. The larger this number is, the more revenue you will make from each click. Unfortunately, many businesses are either under-estimating or over-estimating the value of CPM. By using these formulas, you can see for yourself how high the bar is for success for your particular industry.
