Instagram Follower Growth Tracker
Watch your audience grow with real numbers. Log your follower count whenever you like and get weekly growth rates, a 90-day projection, and a chart of your history.
To track follower growth, log your follower count once a week with the date. This tracker computes your growth per week and per 30 days, projects 90 days out at your current pace, and draws a bar chart of your history. Everything is stored in your browser's local storage, never uploaded.

How tracking works
Growth is noisy day to day: log your follower count with the date, ideally once a week. The tracker sorts entries by date, computes the change between the first and last entry, and annualizes it into per-week and per-30-day rates. The 90-day projection extends your current weekly rate; it is a straight-line guess, not a promise.
Reading the chart
Bars show your follower count at each logged date, scaled to your range. A steady upward slope is healthy growth. Flat stretches mean your content is holding the audience but not reaching new people; drops usually follow a controversial post, a purge of inactive followers, or Instagram removing bots.
What good growth looks like
For small accounts, 2% to 5% per month is solid; for accounts over 100k, 0.5% to 1% per month is normal because the base is large. Compare your rate to your own history, not to viral accounts. A rising rate after a content change tells you the change worked.

Frequently asked questions
How many entries do I need?
At least two entries with different dates. Weekly logging gives the most useful chart; two entries a month apart is the minimum for a meaningful rate.
How is the 90-day projection calculated?
Your current weekly growth rate extended 90 days in a straight line. It assumes nothing changes: no viral posts, no algorithm shifts. Treat it as a baseline, not a forecast.
Where is my data stored?
They stay in your browser's local storage. They are never uploaded or sent anywhere. Clearing your browser's site data deletes them.
Can I fix a wrong entry?
Add an entry with the corrected count and date. The tracker sorts by date, so it slots in correctly. Delete and re-add if you entered the wrong date.
What is a good monthly growth rate?
Small accounts: 2% to 5% per month is solid. Over 100k followers: 0.5% to 1% per month is normal. Compare against your own history first.
My growth is flat. What should I do?
Flat growth usually means your content reaches your current audience but not new people: try reels, collaborations, or trending formats. Drops often follow purges or controversial posts.
How do I add an entry?
Pick a date and enter your follower count. Log weekly for best results.
Is my data sent anywhere?
No. The tracker runs entirely in your browser. You can disconnect from the internet after the page loads and it still works.
