How does the cpm calculator work?
Borrowed from Media buying: CPM = spend / impressions × 1,000
CPM is the main pricing unit for display, video and social ads. Combine it with click-through rate to estimate cost per click.
Worked example
A US brand spends $2,400 and gets 300,000 impressions, so CPM = 2,400 ÷ 300,000 × 1,000 = $8.00.
How should I read my result?
Low CPM
Broad reach at low cost. Check that the audience can actually buy.
Typical CPM
Compare with your past campaigns on the same channel.
High CPM
Narrow or competitive audiences cost more. Check whether conversion rate justifies it.
