> The CPM calculator works out the cost per thousand impressions of an ad campaign from its total cost and impressions, and the impressions or budget you need for a target CPM – and compares two campaigns.

## Inputs

- Campaign A – total cost
- Campaign A – impressions
- Campaign B – total cost
- Campaign B – impressions

## Results

- Campaign A – CPM
- Campaign B – CPM
- Cheaper per thousand impressions

## Formula

```
CPM = total cost ÷ impressions × 1,000
Impressions = cost ÷ CPM × 1,000
Cost = CPM × impressions ÷ 1,000
```

## Explanation

CPM ("mille" is Latin for thousand) is the standard price for display, video and social ads. Typical CPMs range from about $2 on display networks to $10–30 on premium video and LinkedIn.

### How to use the CPM Calculator – Cost per Mille

- **Campaign A – total cost**
- **Campaign A – impressions**
- **Campaign B – total cost**
- **Campaign B – impressions**
- Every result field is editable: type into **Campaign A – CPM** and **Campaign A – impressions** plus every other field update to match.

Results update as you type, and every field accepts the units shown in its menu.

### How it works

Enter the total cost and impressions of campaign A (type into the CPM to work backwards), and optionally campaign B.

### Tips

- Use figures for the same period (a month, a quarter or a year) for every input so ratios compare like with like.
- Track the metric over time – the trend usually tells you more than a single value.
- Compare your result with industry benchmarks, which vary a lot between sectors.
- Treat the result as a starting point for a decision, then check the assumptions behind each input.

### Common mistakes to avoid

- Mixing monthly and yearly numbers in the same calculation.
- Using revenue where the formula needs profit (or the other way round).
- Forgetting hidden costs such as taxes, fees, overheads or your own time.
