Here’s everything you need to know: what it is, why it matters, how to calculate it, and how to optimize it! Formula Average CPM = (Total Spend Across Campaigns ÷ Total Impressions) × 1,000 **Example.** If you spend $2,000 for 400,000 impressions across multiple platforms, your Average CPM is ($2,000 ÷ 400,000) × 1,000 = $5. ## Overview ## What it is Average CPM is the total cost to deliver 1,000 ad impressions across all campaigns and channels. It represents a blended view of CPM across placements and helps you benchmark efficiency. ## Why it matters Average CPM allows marketers to monitor trends over time, compare platform efficiency, and control costs at scale. It’s especially useful for media planning and budget forecasting. ## How it is calculated Add the total cost of all campaigns and divide by total impressions (in thousands). ## Good and bad values ## A good value A good Average CPM depends on your industry and ad format, but anything under $8 is often considered efficient for display and awareness campaigns. ## A bad value A rising Average CPM without improved outcomes can indicate wasted budget or market saturation. ## Do Apply these strategies to improve cost-efficiency across all your advertising. 1. 01 ### Use real-time performance dashboards Monitor CPM trends across campaigns to identify anomalies and shift budget efficiently. 2. 02 ### Compare platforms side by side Analyze CPM by channel—social, display, video—to pinpoint where you’re getting the best value. 3. 03 ### Combine CPM with post-impression metrics Track not just how much you pay for views, but also how those views contribute to conversions or sales. ## Avoid 1. Don’t rely on averages alone—dig into segmented data to understand where budget inefficiencies hide. ## Related metrics ## Related metrics you might be interested in [Average Engagement Rate`= (Total Engagements ÷ Total Impressions or Followers) × 100`](/metrics/average-engagement-rate) [Average Order Value (AOV)`= Total Revenue ÷ Total Number of Orders`](/metrics/average-order-value) [Average Session Duration`= Total Duration of All Sessions ÷ Total Number of Sessions`](/metrics/average-session-duration) [Average Time on Page`= Total Time Spent on Page ÷ (Pageviews – Exits)`](/metrics/average-time-on-page) [Facebook CPM`= (Facebook Ad Spend ÷ Facebook Impressions) × 1,000`](/metrics/facebook-cpm) ## Related articles ## Articles that use Average CPM [![How to calculate an average in Google Sheets: AVERAGE, AVERAGEIF and AVERAGEIFS](https://cdn.owox.com/www/webflow/6a147462338c110acc42a103_AVERAGE-FUNCTIONS-IN-GOOGLE-SHEETS.png/public) google sheets tips · How to calculate an average in Google Sheets: AVERAGE, AVERAGEIF and AVERAGEIFS · Oct 2, 2026](/blog/articles/average-functions-google-sheets) ## Customer stories ## Learn how teams ship analytics faster Organizations that scaled analytics without scaling headcount [All case studies →](/blog/success-stories) [Pürblack · "For 10 years I was blind."
