How to calculate CPM
The formula for CPM a is simple one.
Since CPM is cost per thousand impressions, you simply divide the cost times 1000 by a the number of impressions.
The CPM formula is CPM = 1000 * cost / impressions
You may also want to understand the reverse formulas:
- Cost (how much you’ll have to pay or the total budget):
Cost = CPM * impressions / 1000 - for impressions (how many impressions you’re going to get, given your budget):
Impressions = 1000 * cost / CPM
Buying media using the CPM model has the benefit of being easy to understand and use.
For direct response, performance, CPA, and ROI/ROAS buying advertising on a CPM model, it is important for advertisers to use conversion tracking and optimization to maximize the value of the traffic and how well it will converts.
If it is not possible to measure actual conversions, be sure to measure clicks and to track and optimize your CPC (cost per click). This will allow you to have more predictable costs, but it is up to you to make the traffic convert.
Some advertisers and publishers buy and sell advertising on a CPA (cost per action) model, where the advertiser pays every time the user performs an action (registers, makes a purchase, etc.). This is a very low risk method for advertisers, but it is very high risk for publishers because they have little control over the advertiser’s ability to get the traffic to convert, drive revenue, and monetize the users.
