Enter the number of followers, engagement rate, and share factor into the calculator to estimate the potential reach of a social media post.

Potential Reach Formula

The following formula is used to calculate the potential reach of a social media post.

PR = F * (ER / 100) * SF

Variables:

  • PR is the potential reach
  • F is the number of followers
  • ER is the engagement rate (as a percentage)
  • SF is the share factor, which represents the average number of shares per engaged user

To calculate the potential reach, multiply the number of followers by the engagement rate (as a percentage) and then by the share factor.

What is Potential Reach?

Potential reach is an estimate of the number of people who could see a post on social media based on the number of followers, the engagement rate, and the share factor. It is a useful metric for social media marketers and influencers to understand the possible impact of their content.

How to Calculate Potential Reach?

The following steps outline how to calculate the Potential Reach.


  1. First, determine the number of followers (F).
  2. Next, determine the engagement rate (ER) as a percentage.
  3. Next, determine the share factor (SF), which is the average number of shares per engaged user.
  4. Next, gather the formula from above = PR = F * (ER / 100) * SF.
  5. Finally, calculate the Potential Reach (PR).
  6. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

number of followers (F) = 5000

engagement rate (ER) = 10%

share factor (SF) = 2
