In more detail
Raw follower counts only tell you the total. Follower growth rate tells you the momentum. You calculate it by taking the net new followers gained in a period, dividing that by your follower count at the start of the period, then multiplying by 100. Because it is a percentage, a small account and a large one can be compared on the same footing. It also catches problems early: a flat or negative rate can signal that your content has stopped resonating or that you lost followers after a specific post.
Example
If you start the month with 2,000 followers and end with 2,200, you gained 200 net followers. Divide 200 by 2,000 and multiply by 100, and your follower growth rate is 10 percent for that month.
