How it is calculated
CPM = post cost ÷ reach × 1000 — the same formula as ordinary media CPM, applied to a specific influencer post rather than to an ad campaign as a whole.
Influencer CPM is a handy way to compare different influencers on equal footing even when their price and audience size differ a lot: a low absolute post cost doesn't always mean a good price per reach if the influencer's audience is small.
The metric only accounts for reach, with no adjustment for engagement or audience quality — an influencer with a lower CPM but low engagement or an off-target audience can end up delivering less real value than one with a higher CPM but an active, relevant audience.
