What is CPM Rate Calculator?

A CPM Rate is the price per 1,000 ad impressions charged by a platform or publisher. It's the standard pricing unit for display, video, and programmatic advertising.

Knowing the CPM rate lets you plan campaigns backwards — start with your budget and the rate to estimate how many impressions you'll get. A CPM Rate Calculator does this math instantly.

CPM rates vary by platform (Google $2–$10, Facebook $5–$15, LinkedIn $15–$50), by industry, by targeting specificity, and by seasonality. Understanding rates helps you allocate budget across channels effectively.

How to Calculate CPM Rate — Step by Step

Follow these steps to find the CPM rate for any campaign or estimate impressions from a given rate. Works for all ad platforms and formats.

1

Define your budget

Set the total budget you want to allocate for the campaign or ad placement.

Example

You have $5,000 budgeted for a display campaign.

2

Get the CPM rate or target impressions

If you know the CPM rate, you can estimate impressions. If you know your target impressions, solve for the CPM rate.

Example

The publisher quotes a $10.00 CPM rate.

3

Apply the formula

Impressions = (Budget ÷ CPM) × 1,000. This gives you the total estimated impressions for your budget.

Example

$5,000 ÷ $10.00 × 1,000 = 500,000 impressions

4

Compare rates across publishers

Request CPM rates from multiple publishers and use this calculator to compare impressions per dollar across options.

Example

$10 CPM = 500K impressions vs. $15 CPM = 333K impressions for the same $5,000 budget.
