What is CPM in Meta Ads?
CPM stands for Cost Per Mille, which means the cost to reach 1,000 impressions. An impression occurs every time your ad appears on someone’s screen—regardless of whether they interact with it or not.
The “M” stands for mille, Latin for thousand.
⚠️ CPM is based on impressions, not engagement or clicks.
How is CPM Calculated in Meta Ads?
Formula:
CPM = (Total Ad Spend / Total Impressions) × 1,000
Example:
If you spend $10 and get 4,000 impressions, your CPM = $2.50
🔹 Impressions ≠ Reach
-
Impressions: Total number of times your ad is shown (can include repeat views).
-
Reach: Unique users who saw your ad.
High impressions without high reach means users are seeing your ad multiple times, increasing CPM.
Why is CPM Important?
CPM helps gauge how cost-efficient your ad campaigns are. A lower CPM means you're reaching more people at a lower cost—ideal for brand awareness campaigns.
📈 Use CPM to:
-
Monitor performance
-
Adjust strategies
-
Improve Return on Ad Spend (ROAS)

Common Reasons for High CPM
-
Ad Fatigue
-
Same audience sees your ad too often → lower engagement → Meta sees it as less relevant.
-
-
Low Relevance Score
-
Few clicks or interactions lower your relevance → Meta charges more.
-
-
Poor Audience Targeting
-
Wrong audience → low CTR (Click-Through Rate) → higher CPM.
-
-
Timing
-
During events or holidays, ad space is more competitive → higher CPM.
-
-
Unengaging Ad Content
-
If your ad isn’t creative or appealing → less engagement → higher CPM.
