Formula and example
How it is calculated
CPM = advertising spend / impressions × 1,000
Worked example
€500 / 100,000 impressions × 1,000 = €5.00 CPM.
Things to check
- Compare metrics with the same measurement definitions and time attribution. Depending on the measurement method, more than one conversion per visit is possible.
- Use one currency consistently. Examples use euros; the calculation works with any currency.
