What is CPM (Cost Per Mille)?

CPM means Cost Per Mille. Mille is Latin for one thousand. CPM shows how much you pay for one thousand impressions.

An impression means one view of your ad. When someone sees your ad it counts as one impression. If your ad gets one thousand views that is one thousand impressions. This is why many people call it cost per impression or cost per thousand impressions – the foundation of cost per impression in digital marketing.

For example, if you spend $100 and get 50,000 impressions your CPM will be $2. This means you pay $2 for every one thousand views. Understanding CPM helps you compare ad campaigns and control your budget in a smarter way.

What is an Impression?

Every time someone sees your ad it counts as one impression. CPM measures the cost for every 1,000 of those views.

Why CPM Matters

CPM helps you measure efficiency across platforms. A lower CPM means you reach more people for less money.

Budget Control

When you know your CPM you can plan how much to spend to reach your target audience size.

CPM Formula Explained

The CPM formula is simple and used in every campaign calculation.

CPM = ( Cost ÷ Impressions ) × 1000

Divide total cost by total impressions, then multiply by 1,000.

Let us understand this with a simple example. If your cost is $200 and impressions are 100,000 then: CPM = (200 ÷ 100,000) × 1,000 = $2.

Find Total Cost

(CPM × Impressions) ÷ 1000

Find Impressions

(Cost × 1000) ÷ CPM

Our online CPM calculator does all of this automatically. Enter any two values and the tool instantly calculates the third – whether that is CPM, cost, or impressions.
