No Platform Publishes a Follower Growth Rate, So Every Tool Invents One

What is a follower growth rate?

Tool vendors define follower growth rate as the followers an account gained during a period divided by the followers it held at the start of that period, times 100. No social platform publishes that number. Instagram, LinkedIn, YouTube and X each expose raw follower counts or follower events through their APIs, and the percentage on your dashboard was computed by the dashboard.

The distinction decides how much weight the figure can carry. A platform metric has one definition, one owner and one changelog you can read. A vendor metric has as many definitions as there are vendors, and none of them are wrong, because there is no authority to be wrong against.

Ask your tool which numerator it used before you compare its output to a competitor's number, a benchmark report, or last quarter's deck.

Which platforms publish a follower growth rate?

None of the four largest ones. Here is what each API returns instead, read from each platform's own reference on 10 September 2026.

Platform	What the API returns	Field or endpoint	Rate published
Instagram	"The number of accounts that followed you and the number of accounts that unfollowed you or left Instagram in the selected time period"	follows_and_unfollows	No
LinkedIn	Organic and paid follower counts, lifetime by demographic facet or aggregated across a time range	organizationalEntityFollowerStatistics	No
YouTube	"The number of times that users subscribed to a channel" and "The number of times that users unsubscribed from a channel"	subscribersGained, subscribersLost	No
X	A follower count on the user object, beside following, post and listed counts	public_metrics.followers_count	No

Two of those four hand you both halves of a rate. Instagram and YouTube report gains and losses as separate numbers, so you can build a gross or a net numerator from one request. LinkedIn returns follower totals across a time range, so you subtract two points yourself. X returns a single snapshot integer, so building any rate at all means storing that count day after day before you can measure anything.

How do you calculate follower growth rate?

The convention most tools follow puts new follows over the opening balance:

Follower growth rate = (followers gained in the period / followers at the start of the period) x 100

Run it on real inputs. An Instagram account opens the week with 4,200 followers. Across those seven days, follows_and_unfollows reports 315 follows and 90 unfollows.

Gross growth rate: 315 / 4,200 x 100 = 7.5 percent.

Net growth rate: (315 - 90) / 4,200 x 100 = 5.36 percent.

Same account, same week, same source data, two published percentages two full points apart. Neither is a miscalculation. They answer different questions, and the phrase "follower growth rate" hides which question got answered.

Should the numerator be gross or net?

Use net for any number a decision hangs on. Gross growth counts every new follow and ignores everyone who walked out, so an account shedding its existing audience while one viral post pulls in strangers still reports a healthy week. Net growth subtracts the churn and moves with the size of the audience you actually have.

Keep the gross figure beside it instead of discarding it. Gross measures how much new attention the content pulled in, net measures what stayed, and the gap between them is churn you would otherwise never see. Instagram's follow_type breakdown on follows_and_unfollows is what makes both numbers available from a single call, which is why the split belongs in the body of your reporting and not in a footnote about vanity metrics.

Why do two tools report different growth rates for the same account?

Because each tool made three choices the platforms never made for it. The numerator can be gross follows or net follows. The denominator can be followers at the start of the period, followers at the end, or the average of the two. The period boundary can be a calendar month, a rolling 30 days, or the last complete week in the account's own timezone.

Three small choices produce a wide spread of defensible answers from identical inputs. Run the example above with an end-of-period denominator instead: 315 / 4,425 x 100 = 7.12 percent gross, against 7.5 percent on the opening balance. Nothing about the account changed.

The fix is boring and it works. Write your chosen definition into the report header, keep it fixed across quarters, and treat any external benchmark whose definition you cannot read as uncomparable. That discipline is the same one that separates reach from impressions in a credible analytics deck.

Same week, same account, three published rates

Net growth, start-of-period denominator5.36%

Gross growth, end-of-period denominator7.12%

Gross growth, start-of-period denominator7.5%

What limits sit on the underlying follower data?

Each platform caps how far back the raw numbers go, which caps the periods you can compute over.

LinkedIn's time-bound follower statistics endpoint "will provide statistics from 12 months before the request date (UTC) till 2 days before the request date (UTC)", so a rolling year is the longest window and the two most recent days are absent. Instagram's reference states that follows_and_unfollows is "not returned if the IG User has less than 100 followers", and the Instagram Help Center caps app insights at "any time period within the past 90 days". LinkedIn also moved the plain total out of the statistics endpoint: it "no longer returns totalFollowerCounts", and the current denominator comes from the networkSizes API instead.

Anything longer than those windows has to come from your own stored history. Pull the daily numbers on a schedule and keep them, or accept that your year-over-year chart cannot exist.

Is follower growth rate worth reporting at all?

Yes, as a trend line on a fixed definition, and no as a comparison against anyone else. Followers are the one number every platform still publishes plainly, so the rate built on top is the cheapest longitudinal signal you have. It stops being useful the moment you set it beside a figure whose formula you cannot inspect.

Pair it with a metric that measures behaviour instead of headcount. Engagement rate against reach tells you whether the audience you gained does anything, and a growing follower count attached to a falling engagement rate is the pattern worth catching early.

How should you track follower growth across networks?

Pull the raw counts from every network on the same schedule, store them, and compute one rate yourself. That way the definition is yours, the period boundary is yours, and the cross-network comparison is honest because every column came out of the same formula.

That collection job is what social media analytics in adaptlypost handles across the networks you already publish to, with per-network views like the Instagram analytics tool and the LinkedIn analytics tool reading from the same stored history. Publishing and measuring from one place also means the posts that moved the number are sitting next to the number.

Frequently asked questions

Does Instagram show a follower growth rate in the app?

No. The Instagram app shows Total followers with a Growth entry that Meta describes as the "number of followers you've gained or lost", which is a count, not a percentage. Any rate you see attached to an Instagram account came from a third-party tool that divided that count by a denominator of its own choosing.

What is a good follower growth rate?

There is no platform-published benchmark, because there is no platform-published metric to benchmark. Any figure quoted as an industry standard came from one vendor's sample, using that vendor's formula, over that vendor's date range. Compare your account to its own previous periods on a fixed definition instead.

Should I use followers at the start or the end of the period?

Start, if you want the number to answer "how much did we grow relative to where we began". The end-of-period denominator is always larger during growth, so it reports a smaller percentage for identical performance. Pick one, write it down, and never switch mid-year.

Can I calculate follower growth rate for X?

Only if you store the data first. The X API's user object exposes public_metrics.followers_count, a snapshot of the current total with no gained or lost breakdown. Two snapshots taken a week apart give you a net change, and nothing in the API tells you how many people followed and unfollowed inside that week.

Does follower growth rate include paid followers?

That depends on the platform and on your tool. LinkedIn's follower statistics endpoint returns organicFollowerCount and paidFollowerCount as separate fields, so the split is available there. Instagram's follows_and_unfollows publishes no organic-versus-paid breakdown, so a rate built from it mixes both.

How long a period should I measure over?

Long enough that a single post cannot dominate the result. A weekly rate on a small account swings wildly on one lucky reel, while a rolling 30-day window smooths that out and still updates fast enough to act on. LinkedIn's 12-month ceiling on time-bound follower data sets the practical upper bound for a like-for-like cross-network view.

Why does Instagram stop reporting follow and unfollow data for small accounts?

Instagram's follows_and_unfollows field is not returned once an account has fewer than 100 followers, per Instagram's own reference. Below that threshold there is no gain or loss figure to build a rate from, gross or net. An account has to cross 100 followers before any growth rate becomes computable at all.

Why is LinkedIn's follower data always a couple of days behind?

LinkedIn's time-bound follower statistics endpoint returns data from 12 months before the request date up to 2 days before it, so the most recent two days never show up in the response. A growth rate pulled today reflects activity through two days ago, not through today. Build that lag into the report's date range rather than the day the report runs.

Where does LinkedIn's follower total come from now that totalFollowerCounts is gone?

LinkedIn removed totalFollowerCounts from its follower statistics endpoint, so a rate's denominator can no longer come from that field. The current total comes from the networkSizes API instead. A tool built before that change and never updated is reading a field that no longer exists there.

Why can't I build a year-over-year follower growth chart straight from the platform APIs?

LinkedIn's time-bound follower statistics cap out at 12 months back, and Instagram's Help Center caps app insights at the past 90 days, so neither API holds enough history for a true year-over-year comparison. The only way past that ceiling is your own stored daily counts, pulled and kept on a schedule before you need them. Wait to start collecting, and the comparison simply will not exist later.
