Understanding CPM (Cost Per Mille) is essential for anyone involved in digital advertising. Whether you’re a marketer, advertiser, or business owner, knowing how to calculate CPM helps you plan campaigns, manage your budget, and maximize ROI.

In this article, you’ll learn everything you need to know about using a CPM calculator, how to calculate CPM manually, and how to estimate impressions using CPM—with clear examples and formulas.

✅ What Is a CPM Calculator?

A CPM calculator is a tool used to determine the cost per thousand ad impressions. “Mille” is Latin for one thousand, and CPM is a standard pricing model in display, social media, and video advertising.

Using this calculator lets advertisers:

• Forecast campaign reach

• Compare ad network costs

• Make informed budgeting decisions

🧠 How to Calculate CPM Manually

You don’t always need a tool. You can calculate CPM manually with this simple formula:

CPM = (Total Ad Spend ÷ Total Impressions) × 1,000

Example:

If your total cost is $250, and your ad receives 50,000 impressions, the CPM is:

CPM = ($250 ÷ 50,000) × 1,000 = $5

That means you’re spending $5 per 1,000 impressions.

🔄 How to Calculate Impressions from CPM

Wondering how many impressions you’ll get for your budget? Here’s how to calculate impressions from CPM:

Impressions = (Total Budget ÷ CPM) × 1,000

Example:

With a $400 budget and a CPM of $8:

Impressions = ($400 ÷ $8) × 1,000 = 50,000 impressions

This is especially useful when planning reach or negotiating ad space.
