Instagram insights for follower growth: which numbers to watch

In short: watch three numbers: net new followers each week, follows per post, and how many non-followers engaged. Together they show whether you are reaching new people and convincing them to stay.

Where to find insights

With a professional account, open your profile and tap Insights in the professional dashboard. Instagram shows total follower insights, such as growth and where followers are, once an account has at least 100 followers.

The numbers that matter

NumberWhat it tells youHow to use it
Net new followers per weekFollowers gained minus unfollowsYour real pace toward 1,000
Follows per postHow many people followed after that postDivide by accounts reached × 1,000 to compare posts fairly
Accounts engaged: followers vs non-followersWho interactedA rising share of non-followers means you are reaching new people

Formulas

  • Follower growth rate = net new followers in the period ÷ followers at the start × 100.
  • Follows per 1,000 reached = follows from a post ÷ accounts reached × 1,000.

Worked example: you start the month with 400 followers and end with 460, so the growth rate is 60 ÷ 400 × 100 = 15%. A Reel that reached 2,400 accounts and brought 12 follows scores 5 per 1,000; a photo that reached 600 and brought 6 scores 10 per 1,000, so the photo convinced more of the people who saw it.
