If you are trying to work out the CPvM of a campaign, use our handy CPvM Calculator below. We also help you to work out how many viewable ad impressions you have so you can use this to work out how much you can get from this ad pricing model.

Our CPvM Calculator will help you understand this pricing model better, by letting you experiment with different scenarios.

**Note**: use our Viewability Rate Calculator to work out how many viewable impressions you have if you don’t already know.

## What Does CPvM Mean?

Also known as vCPM. CPvM stands for Cost Per Viewed Thousand Impressions and means that a payout is triggered every time a thousand ads are viewed. The M means thousand as it is the roman numeral for 1,000.

CPvM is a variation of CPM in that when you pay on a CPM basis you are paying for every time a thousand ads are loaded. On a CPvM basis, however, the ad has to actually appear on screen (well at least 50% of it does for one second).

CPvM is also commonly referred to as Cost Per Viewable Impression (or occasionally viewable cost per thousand impressions). As you generally pay for ad campaigns once they are finished Cost Per Viewed Impressions makes the most sense.

## CPvM Formula

The equation for CPvM (or vCPM) is:

**CPvM = (Cost ÷ viewable impressions) x 1000 **

*(it could also be expressed as: CPvM = (Cost ÷ ad impressions) x 1000 x % viewed)*
