CPM CalculatorCost Per Impression = Total Cost / ImpressionsYou spent $250 on a display campaign that generated 100,000 impressions:
$250 / 100,000 = $0.0025 per impressionThe CPM equivalent is $0.0025 × 1,000 = $2.50.
Cost per impression is the price an advertiser pays every time their ad is displayed to a user once. It is the smallest unit of ad cost measurement and forms the basis for CPM-based pricing models used across display, video, and social advertising platforms.
While CPM bundles the cost into groups of 1,000 views, looking at the per-impression rate gives you a precise understanding of how efficiently your budget is being spent on each individual ad display.

These two metrics describe the same underlying cost but at different scales. Understanding both helps you communicate with ad platforms and compare rates across vendors.
| Metric | What It Measures | Conversion |
|---|---|---|
| Cost Per Impression | Cost for a single ad view | CPM / 1,000 |
| CPM | Cost for 1,000 ad views | Cost Per Impression × 1,000 |
Cost per impression is the amount an advertiser pays each time their ad is displayed once. It represents the cost of a single ad view, regardless of whether the viewer interacts with the ad.
Divide your total advertising spend by the total number of impressions. For example, $250 spent on 100,000 impressions gives $250 / 100,000 = $0.0025 per impression.
Not exactly. Cost per impression is the price for a single ad view. CPM is the price for 1,000 impressions. You can convert between them: CPM = cost per impression × 1,000.
A good cost per impression varies by industry and platform. On display networks, rates typically range from $0.001 to $0.01 per impression. Video ads and premium placements usually cost more. Comparing your rate against industry benchmarks helps determine if your spend is competitive.
Cost per impression helps you understand the raw efficiency of your ad spend at the most granular level. It lets you compare pricing across campaigns with different impression volumes and is the foundational unit behind CPM-based buying.
