Frequently Asked Questions

What does CPM stand for?

CPM stands for "Cost Per Mille" (thousand). It represents the cost of 1,000 advertisement impressions on a web page.

How do I calculate CPM?

CPM = (Total Ad Spend / Total Impressions) × 1,000. It helps compare the cost-efficiency of campaigns with different reach. Enter your ad spend and impressions in Planning mode to also see your margin-adjusted CPM.

What is a good CPM for digital advertising?

CPM varies enormously by channel, audience, season, and auction conditions — there's no fixed 'good' number, and typical ranges shift constantly as ad platforms change. Rather than comparing to a generic industry figure, compare your CPM across your own campaigns and channels, and remember that a lower CPM is not always better — a targeted audience with a higher CPM may convert far better than broad, cheap impressions.

How do I convert CPM to CPC?

CPC = CPM / (CTR × 10). For example, a $5 CPM with 1% CTR gives a $0.50 CPC. Use the CPC calculator to model this conversion along with budget-to-clicks planning.
