Cost Per Impression Calculator
In today’s digital advertising world, understanding where your money goes is critical. One of the most essential metrics in online marketing is Cost Per Impression (CPI). Whether you're managing Google Ads, Facebook campaigns, or running banner ads, knowing how much you're paying per impression can help you measure campaign efficiency and plan your budget effectively.
The Cost Per Impression Calculator is a simple yet powerful tool to give you quick insights into your ad spend. It breaks down your campaign cost relative to the number of times your ad was shown, enabling smarter and more data-driven decisions.
Formula
The formula for calculating Cost Per Impression is very straightforward:
Cost Per Impression (CPI) = Total Cost / Total Impressions
This means you divide how much money you spent on the campaign by how many times your ad was displayed to users.
For example, if you spent $100 and got 20,000 impressions, then:
CPI = 100 / 20,000 = $0.005 per impression
How to Use the Calculator
Using the Cost Per Impression Calculator is very simple. Here's how:
- Enter the Total Cost: Input how much you spent on the campaign in dollars.
- Enter the Total Impressions: Type the total number of times your ad was shown.
- Click Calculate: The calculator will instantly display your CPI result.
That’s it. With this info, you can compare campaigns or check if you're within your budget targets.
Example
Let’s say you're running a display ad campaign.
- Total Cost: $500
- Total Impressions: 100,000
Using the formula:
500 / 100,000 = 0.005
So your Cost Per Impression is $0.005 — that’s half a cent per ad view. This allows you to evaluate whether the campaign is cost-efficient based on your goals.
