1. What is Average Reach?

Average Reach measures the mean number of unique people exposed to content over multiple periods. It helps understand the typical audience size across campaigns or timeframes.

2. How Does the Calculator Work?

The calculator uses the Average Reach formula:

Where:

• Total Reach — Sum of unique viewers across all periods
• Number of Periods — Count of measurement timeframes

Explanation: The equation divides cumulative unique audience by the number of measurement periods to find the mean reach.

3. Importance of Average Reach Calculation

Details: Average Reach helps compare campaign performance, allocate budgets effectively, and understand audience consistency across time periods.

4. Using the Calculator

Tips: Enter total unique reach across all periods and the number of periods measured. Both values must be positive numbers.
