Enter the initial and final audience sizes into the calculator to determine the audience growth rate. This calculator helps to evaluate the percentage increase or decrease in audience size over a period.

Audience Growth Rate Formula

The following formula is used to calculate the audience growth rate:

AGR = ((F - I) / I) * 100


  • AGR is the audience growth rate (%)
  • F is the final audience size
  • I is the initial audience size

To calculate the audience growth rate, subtract the initial audience size from the final audience size, divide by the initial audience size, and then multiply by 100 to get the percentage.

What is Audience Growth Rate?

Audience growth rate is a measure of how much an audience has increased or decreased in size over a specific period. It is a critical metric for businesses, content creators, and marketers to understand the effectiveness of their strategies in attracting and retaining an audience. A positive growth rate indicates an increase in audience size, while a negative growth rate suggests a decrease.

How to Calculate Audience Growth Rate?

The following steps outline how to calculate the Audience Growth Rate.

  1. First, determine the initial audience size (I).
  2. Next, determine the final audience size (F).
  3. Use the formula AGR = ((F – I) / I) * 100 to calculate the growth rate.
  4. Finally, calculate the Audience Growth Rate (AGR) in percentage.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.
