CPM (Cost Per Mille)

Ad spend per 1,000 impressions.

Formula

CPM = ad spend / impressions x 1,000

Interpretation

CPM describes the price of reach. It depends on inventory, auction, audience, placement and campaign type; comparisons only make sense within an identical scope.

Benchmark context

For Amazon Sponsored Ads, the research we checked found no reliable, dated platform-wide benchmark. We therefore deliberately do not invent a number; use your own campaign-level CPM with a documented period.

Source / as of: Source status: research lane check of 2026-05-06; no reliable platform benchmark found.
