Calculate CPM
What is CPM?
CPM stands for "Cost Per Mille" (mille = Latin for thousand). It's the price you pay for 1,000 ad impressions—each time your ad is displayed to a viewer counts as one impression.
Formula: CPM = (Total Ad Spend ÷ Impressions) × 1,000
CPM is the standard pricing model for brand awareness campaigns where the goal is maximizing visibility rather than clicks or conversions.
CPM vs CPC vs CPA
| Model | You Pay For | Best For |
|---|---|---|
| CPM | 1,000 impressions | Brand awareness, reach campaigns |
| CPC | Each click | Website traffic, engagement |
| CPA | Each action (sale, signup) | Direct response, conversions |

Factors That Affect CPM
- Audience targeting: Narrow targeting (e.g., "CFOs in tech") costs more than broad targeting
- Ad format: Video > rich media > display banners
- Placement: Above-the-fold, homepage placements command premiums
- Seasonality: Q4 (holiday season) has highest CPMs; January is typically lowest
- Industry: Finance, insurance, and legal have highest CPMs
- Geography: US/UK/Canada typically cost 2-5x more than developing markets
- Device: Desktop often has higher CPM than mobile
When to Use CPM Pricing
✅ CPM is good for:
- Brand awareness campaigns
- Product launches needing maximum visibility
- Retargeting campaigns with high click-through rates
- Predictable budgeting (you know exactly how many impressions you'll get)
❌ Consider alternatives when:
- You need direct conversions (use CPA bidding)
- You have limited budget and need guaranteed engagement (use CPC)
- Your ads have low click-through rates
eCPM: Effective CPM
eCPM lets you compare campaigns using different pricing models by normalizing everything to a CPM basis.
Formula: eCPM = (Total Earnings ÷ Total Impressions) × 1,000
Example: A CPC campaign costing $50 that got 100,000 impressions has an eCPM of $0.50—much cheaper than paying $5 CPM directly.
