*Numbers are rounded to the nearest hundredths.
CPM stands for 'Cost Per Mille'; that's cost per a thousand impressions. One impression is one potential customer viewing an advertisement once. CPM is calculated by dividing the total cost by the number of impressions and multiplying the result with 1000.
Here is the CPM formula:
CPM = (Total cost / Impressions) x 1,000
Don't forget the last part! If you don't multiply by a thousand, what you get is the cost of ONE impression. You need to add "x 1,000" to get the cost of A THOUSAND impressions.
For example, if you spend $5,000 for an advertisement and get 250,000 impressions, the CPM of that campaign is $20.
If you need to work out the total cost from the known CPM price and impressions, use the following formula.
Total cost = (Impressions x CPM) / 1,000
If you want to estimate the number of impressions you can get from the known CPM rate and the given budget amount, use the below formula.
Impressions = (Total cost x 1,000) / CPM
