Formula

CPM helps compare impression-based buys. Pair it with CTR and conversion rate to estimate whether low impression cost can turn into useful revenue.

Formula

CPM = campaign cost / impressions * 1,000. Clicks = impressions * CTR. Orders = clicks * conversion rate.

Example

Newsletter sponsorship estimate

A sponsorship costs $1,500 for 250,000 impressions, with 1.5% CTR and 2.5% conversion from clicks.

Campaign cost: $1,500
Impressions: 250,000
CTR: 1.5%
Conversion rate: 2.5%

The example has a $6.00 CPM, about 3,750 clicks and roughly 94 orders.

FAQ

What does CPM mean?

CPM means cost per thousand impressions. It is common for display ads, sponsorships, newsletters and awareness campaigns.

Is a low CPM always good?

No. Cheap impressions can still perform poorly if they do not generate qualified clicks, leads or orders.

Can CPM be compared across channels?

Yes, but compare downstream quality too. A higher CPM can be better if conversion rate or order value is much stronger.

Important limits

Impression quality varies across placements, countries and audiences.
Use CPM with CTR, conversion rate and revenue data before judging performance.
