Reddit CPM

The short answer
Reddit for Business documents a self-serve auction with advertiser-set budgets and platform minimums; it publishes no average CPM. Reddit's reputation as a cheap-reach channel comes from advertiser anecdote, not a dated tracker, so we state the reputation as reputation and print no number.
The contextual angle is the point
Reddit's distinctive inventory is not demographic, it is topical: subreddit and community targeting puts your ad inside a conversation about your exact category. In a post-cookie market where behavioral signal keeps degrading, context is the targeting that does not expire. An impression in r/homelab for a NAS vendor is a different product from an interest-bucket impression modeled from browsing history, even at an identical CPM.
The catch behind cheap reach
- Ad-averse culture. Redditors treat obvious advertising roughly. Low CPMs paired with low engagement is the classic pattern; the impression was cheap because attention was not included.
- Anecdote pricing. Every Reddit CPM figure in circulation is an undated advertiser anecdote. Your bounded test, computed in the calculator, replaces all of them for your account.
- Minimums exist.Reddit's self-serve flow applies platform minimums documented in its business help; they gate very small tests, not serious ones.
