CPM Calculator (Cost Per 1,000 Impressions)
CPM (cost per mille, "mille" being Latin for thousand) tells you how much you're paying for every 1,000 ad impressions — enter your total spend and impressions to see the rate.
CPM is most useful for comparing the cost-efficiency of awareness and reach campaigns, where the actual goal is getting a message in front of eyeballs rather than driving an immediate click or purchase — for those click- or conversion-focused goals, CPC or CPA are generally the more relevant metrics instead. Because CPM strips out everything except raw exposure cost, it's also the standard way media buyers compare pricing across very different ad formats and platforms on an apples-to-apples basis.
- Formula: CPM = (Total Spend ÷ Impressions) × 1,000.
- Example: (500 USD ÷ 250,000) × 1,000 = 2.00 USD per 1,000 impressions.
- Best for awareness campaigns: CPM is most useful for comparing the cost-efficiency of reach/brand-awareness campaigns, where the goal is impressions rather than clicks or conversions.
How is CPM different from CPC?
CPM charges (or measures cost) per 1,000 views/impressions regardless of clicks, while CPC (cost per click) only counts when someone actually clicks the ad.
What's a "good" CPM?
It varies enormously by platform, audience, and format — display ads often have low CPMs (a few dollars), while premium video or highly targeted audiences can run much higher.
