## Definition

CPM, or cost per mille, is a fundamental metric in digital advertising representing the cost an advertiser pays for every one thousand impressions of an advertisement. A CPM calculator computes either the CPM rate, the total advertising budget, or the total number of impressions by reorganizing the formula CPM = (Cost / Impressions) * 1000. Marketing professionals, media planners, and publishers use this calculation to evaluate the cost-efficiency of online advertising campaigns, compare different media channels, and estimate campaign expenses.

2. **Enter known parameters** — Input the two values you already know into their respective fields.
