1. What is CPM on Facebook?

CPM (Cost Per Mille) on Facebook represents the cost an advertiser pays for one thousand impressions of their ad. It's a key metric for measuring the cost-effectiveness of Facebook advertising campaigns.

2. How Does the CPM Calculator Work?

The calculator uses the CPM formula:

Where:

• \( Spend \) — Total advertising spend in dollars ($)
• \( Impressions \) — Total number of ad impressions

Explanation: The formula calculates how much it costs to reach one thousand people with your ad, helping advertisers compare the efficiency of different campaigns.

3. Importance of CPM Calculation

Details: CPM is crucial for budget planning, campaign optimization, and comparing advertising efficiency across different platforms and campaigns. Lower CPM indicates more cost-effective reach.

4. Using the Calculator

Tips: Enter your total ad spend in dollars and the total number of impressions received. Both values must be positive numbers (spend ≥ 0, impressions > 0).
