Benchmark context

What this calculator means

CPM: CPM (Cost Per Mille) is the cost to show your ad 1,000 times. Facebook averages $7.19 CPM, Google Display averages $2.80, and LinkedIn averages $8.50 across industries.

Formula and example

CPM = Total Spend / (Total Impressions / 1,000); Cost per impression = Total Spend / Total Impressions

If you spent $1,000 and got 100,000 impressions, your CPM is $10.00 and each impression costs $0.01.

Methodology & assumptions

Last updated: 2026-06-25

Calculation method

Divides total ad spend by impressions in thousands to produce CPM. Also computes the per-impression cost. CPM is the standard metric for brand awareness and display advertising campaigns where clicks aren't the primary goal.

Data sources

Uses the numbers you enter and standard small-business finance formulas. Benchmark comparisons use HustleFin industry benchmark pages where available.

Limitations

CPM doesn't measure engagement, clicks, or conversions — it only measures reach. A low CPM with poor targeting wastes budget. Best used for awareness campaigns; for performance campaigns, use CPC and ROAS instead.

Input definitions

Total ad spend: Total amount spent on the ad campaign.
Total impressions: Total number of times your ad was displayed.
