# What is CPM?

CPM or Cost per mile, as the name suggest, you simply need to divide your average earning cost by your average number of impressions, multiplied by a thousand. Average CPM formula: CPM = 1000 * cost / impressions.

CPM can change drastically depending on your Advertising tier, traffic source, country, device, operating system and many other variables.
