Facebook Page Growth Calculator
Estimate how your Facebook page followers could grow over time based on your starting audience, monthly growth rate and content performance.
Overview
This Facebook Page Growth Calculator helps you estimate how your page followers may grow over time using your current audience size, expected monthly new followers, posting activity and an extra monthly growth rate. It is useful for setting follower targets and comparing different content plans.
How it works
The calculator combines two types of growth. First, it adds a fixed monthly follower gain based on your expected new followers and the followers generated by your posting activity. Second, it applies an additional monthly percentage growth rate to model compounding growth over time. This gives an estimated follower total at the end of the selected period, along with the net gain and average monthly increase.
