Cost Per Impression Calculator
In today’s data-driven marketing world, understanding how efficiently your advertising dollars are working is essential. One key performance metric used by advertisers and marketers is Cost Per Impression (CPI)—a vital indicator of how much you are paying for each view of your ad.
Our CPI Calculator helps you instantly analyze your advertising efficiency across different currencies and impression scales. Whether you’re a digital marketer, agency analyst, small business owner, or media buyer, this tool makes it easy to evaluate your campaigns with precision.
🔍 What Is CPI (Cost Per Impression)?
Cost Per Impression refers to the cost of a single ad view. This metric is particularly useful for awareness-focused campaigns where reach is more important than clicks or conversions. While often used interchangeably with CPM (Cost Per Mille)—which is the cost per 1,000 impressions—CPI provides a granular look at campaign performance.
Formula:
CPI = Total Cost / Total Impressions
CPM = CPI × 1,000

💡 Example: Measuring Campaign Efficiency
Let’s say you ran a brand awareness campaign with these details:
- Campaign Name: “Summer Sale 2025”
- Total Cost: $5,000
- Impressions: 2,000,000
- Currency: USD
- Impression Unit: 1,000 (CPM)
Calculation:
- CPI: $5,000 / 2,000,000 = $0.0025
- CPM: $0.0025 × 1,000 = $2.50
Industry Comparison:
Your CPM matches the industry average ($2.50), meaning your campaign is performing as expected in terms of cost-efficiency.
