Formula
CPM = campaign cost ÷ impressions × 1,000; campaign cost = impressions × CPM ÷ 1,000; impressions = campaign cost × 1,000 ÷ CPM.
Worked example

Assumptions and limits
- All values refer to the same campaign scope and period; a positive cost cannot be paired with zero CPM, and the result does not measure conversions or incrementality.
- CPM Calculator treats the entered values as estimates and does not infer missing project, account, or personal details.
- Calculations retain working precision except where the cited method requires an intermediate rounding step; displayed values are then formatted separately. Source rules and dated rates must be rechecked when they change.
