The CPM formula, three ways round

CPM is what 1,000 impressions cost. Know any two of cost, impressions and CPM and the calculator solves the third.

What $100 of ads buys at four CPMs

Double the CPM and the same budget reaches half the people. That buys reach. Judge an ad by what each sale costs.

Arithmetic only: round CPMs to show the scale. Each platform sets its own.

From CPM to cost per sale

Add your click-through and conversion rates and the same spend becomes a cost per click and per sale. Compare that with your break-even ROAS, or what a sale pays on the TikTok Shop calculator.

More about CPM calculator

Give any two of cost, impressions and CPM and get the third, then what those views turn into at your click-through and conversion rates.

How to use CPM calculator, step by step

  1. Pick what to work out. CPM, the total cost or the number of impressions.
  2. Fill in the other two. From your ad report, a media kit or a creator's quote. Views work as impressions.
  3. Add your rates (optional). Click-through and conversion rates give clicks, results and the cost of each.

How do you calculate CPM?

CPM is cost per thousand impressions: total cost ÷ impressions × 1,000. $250 for 40,000 impressions is a $6.25 CPM. Turned around, cost = CPM × impressions ÷ 1,000.

If it doesn't work

The result says 0 or nothing

Fill in exactly two of cost, impressions and CPM; the calculator works out the third.

A creator quoted per video, not per view

Use the views you expect as impressions and the quote as the cost to get a CPM you can compare.

CPM calculator FAQ

What does CPM stand for?

Cost per mille: mille is Latin for thousand. It's the price of 1,000 impressions, the standard unit ad platforms bill and report reach in.

What's a good CPM?

It moves with the platform, country, audience, season and the ad. Compare with your own past campaigns and judge an ad by cost per result: a cheap CPM nobody clicks costs more per sale.

What's the difference between CPM, CPC and CPA?

CPM is cost per 1,000 impressions, CPC cost per click and CPA cost per result (a sale or sign-up). The calculator gives all three from one set of numbers.

How do I price a sponsored video by CPM?

Expected views × CPM ÷ 1,000: 20,000 views at a $15 CPM is $300. For UGC the brand posts, our UGC rate calculator prices by deliverables and usage rights.

Are impressions the same as views?

Not always. An impression is the ad shown; a view may need a few seconds watched. Use whichever your report counts, the same across campaigns.
