How to Calculate CPM
Use this formula when you know the total cost and total impressions
CPM = (Total Cost / Total Impressions) × 1000 Example: $500 spent for 250,000 impressions: ($500 / 250,000) × 1000 = $2.00 CPM
How to Calculate Total Cost
Use this formula when you know the CPM and total impressions
Total Cost = (CPM × Total Impressions) / 1000 Example: $2.00 CPM for 250,000 impressions: ($2.00 × 250,000) / 1000 = $500
How to Calculate Total Impressions
Use this formula when you know the total cost and CPM
Total Impressions = (Total Cost / CPM) × 1000 Example: $500 budget at $2.00 CPM: ($500 / $2.00) × 1000 = 250,000 impressions

Frequently Asked Questions
Common questions about CPM and advertising metrics
A 'good' CPM varies widely by industry, platform, and targeting. Generally, $1-$2 is considered low, $5-$10 is average, and $15-$30 might be normal for highly targeted or premium campaigns. The most important factor is whether your CPM delivers positive ROI for your specific business goals.
CPM (Cost Per Mille) measures the cost per 1,000 impressions, while CPC (Cost Per Click) measures the cost for each click on your ad. CPM is impression-based pricing, while CPC is performance-based pricing where you only pay when users click.
To lower your CPM: 1) Refine your audience targeting (but not too narrow), 2) Improve your ad quality score, 3) Test different ad placements, 4) Optimize your bidding strategy, 5) Schedule ads during less competitive times, and 6) Regularly refresh your creative to maintain engagement.
CPM is typically better for brand awareness campaigns where impressions matter most. CPC is usually better for performance campaigns focused on driving specific actions. For new campaigns, CPC often provides a safer starting point as you only pay for actual clicks.
CPM (Cost Per Mille) is what advertisers pay per 1,000 impressions. RPM (Revenue Per Mille) is what publishers earn per 1,000 impressions. For the same ad impression, RPM is typically lower than CPM because ad platforms take a percentage of the advertiser's payment before paying the publisher.
