CPM calculation examples
Below are practical examples showing how CPM works in real scenarios and how it helps advertisers better control and plan their ad budgets.
Calculating CPM
Campaign budget: $2,000
Total impressions: 500,000
CPM = (2,000 ÷ 500,000) × 1,000 = $4
Result: $4
In this scenario, the advertiser spends $2,000 to generate 500,000 impressions. The resulting CPM is $4, meaning the advertiser pays $4 for every 1,000 impressions.
Calculating total campaign cost
Total impressions: 200,000
CPM: $8
Total cost = (200,000 ÷ 1,000) × 8 = $1,600
Result: $1,600
When CPM and impressions are known, this method allows advertisers to estimate the full campaign cost.
Estimating impressions based on budget
Campaign budget: $1,500
CPM: $5
Impressions = (1,500 ÷ 5) × 1,000 = 300,000
Result: 300,000
This example demonstrates how to forecast reach using a defined budget.
