What Is Cost Per Impression?
Before we dive into formulas and calculators, letâs start with the basics. Cost per impression, often abbreviated as CPI, refers to how much you pay each time your ad is shown to someone. Itâs commonly used in display advertising, YouTube ads, and Google Ads where visibility is the goalânot clicks or conversions.
For example, if you spend $100 and your ad is shown 10,000 times, your cost per impression is $0.01.
It sounds simple, but calculating cost per impression accurately means understanding how platforms like Google Ads and YouTube charge advertisers.

How to Calculate Cost per Impression

The cost per impression formula is:
Cost Per Impression (CPI) = Total Advertising Cost á Number of Impressions
So if you’re running a YouTube pre-roll campaign and you spent $250 for 50,000 views, your CPI is:
$250 á 50,000 = $0.005 per impression
That means youâre paying half a cent every time someone sees your ad.

Google Adsense Cost per Impression: What You Should Know
For publishers using Google AdSense, cost per impression ads often pay out based on CPM (Cost per Mille)âmeaning cost per thousand impressions.
For example, a $2 CPM means you earn $2 for every 1,000 ad impressions served on your site.
âĄď¸ If you’re an advertiser, it’s the same logicâyour budget will be divided by every 1,000 views of your ad. This makes calculating cost per impression incredibly useful when managing display campaigns.
YouTube Cost per Impression Metrics
YouTube offers several different ad formatsâskippable, non-skippable, bumper, and displayâand each comes with different CPI rates. According to YouTubeâs ad pricing guide, some formats are priced by cost per view (CPV), while others rely on cost per 1,000 impressions (CPM).
When using YouTubeâs CPM model, your YouTube cost per impression can vary depending on:
- Audience targeting
- Ad format
- Video content relevance
- Competition for ad space

Cost Per Click vs Cost Per Impression
Letâs break down the difference between cost per click and cost per impression:
| Metric | Focus | Best For |
| Cost Per Click (CPC) | Action (clicks) | Driving traffic to your website |
| Cost Per Impression | Awareness (visibility) | Brand exposure and visual messaging |
In other words, if you want engagement, go with CPC. If you want visibility, opt for impression-based bidding.

When to Use Cost Per Impression Ads

Not every business benefits from CPI bidding. Hereâs when it shines:
- Brand Awareness Campaigns â Launching a new product? You want people to see your name everywhere.
- Retargeting Display Ads â Keep your brand top-of-mind after a user visits your site.
- YouTube Sponsorships â Get your product in front of the right audience even if they donât click.

Cost Per Thousand Impressions Calculator (CPM vs CPI)
While CPI is the cost per one impression, many ad platforms calculate CPM (Cost per Mille = 1,000 impressions). Use this adjusted formula:
CPM = (Total Advertising Cost á Total Impressions) x 1,000
If your CPI is $0.01, your CPM is:
0.01 x 1,000 = $10
Understanding this relationship helps marketers compare performance across platforms. Itâs also useful when using tools like our SEO Software Stack for performance analysis.
