Economics & FinanceWhat is cost per mille?
Cost per mille (CPM) is a standard advertising pricing metric that denotes the financial cost an advertiser incurs for every one thousand impressions or views of an advertisement. Derived from the Latin word mille meaning thousand, it serves as a universal baseline for assessing the cost efficiency of media distribution across print, television, and digital platforms.
In short
In digital marketing auctions, CPM allows advertisers to evaluate audience acquisition costs across competing advertising networks. By standardizing pricing per thousand deliveries, marketers calculate the financial efficiency of reaching target segments on platforms like Google, YouTube, Meta, or TikTok. Comparing programmatic CPM benchmarks against organic distribution illuminates the economic value of earned media.

Overview
Cost per mille represents one of the most foundational valuation metrics across historical and programmatic advertising economics. Originally utilized in radio, television, and print journalism to price circulation reaches, CPM transitioned into the programmatic digital ecosystem as the default pricing mechanism for brand awareness campaigns. Rates vary drastically depending on audience demographic purchasing power, platform competition, and seasonal demand. Media planners employ CPM to optimize cross-channel budget allocations and estimate the financial return of promotional investments.
