How it works: Divides your total campaign cost by the total number of impressions to find the cost of a single view.

What is CPI?

Cost Per Impression (CPI) measures exactly how much you pay for a single view of your ad. Unlike CPM which groups costs by thousands, CPI gives you the granular cost of one individual impression, making it useful for precise budget tracking and small-scale campaigns.

CPI Formula

The formula is simple:

CPI = Total Cost / Total Impressions

Frequently Asked Questions

CPI vs CPM: What's the difference?

CPI is the cost for ONE impression, while CPM is the cost for ONE THOUSAND impressions. CPI = CPM / 1000. Use CPI for granular analysis and CPM for general campaign budgeting.

What is a good CPI?

A "good" CPI depends heavily on your industry. Generally, anything under $0.01 per impression is considered efficient for broad reach campaigns, while highly targeted B2B campaigns might have higher CPIs.

Does a lower CPI mean better performance?

Not always. A very low CPI might mean you're getting cheap impressions from irrelevant audiences. It's important to balance low costs with conversion metrics like CTR and ROAS.
