The short answer
Brand accounts grew roughly 11-22% over the whole of 2025 — about 1-2% per month, and slowing. Socialinsider's benchmark of 447,613 brand pages measured 2025 audience growth at 22% for small accounts (1-5K followers) tapering to 11.25% for large ones (100K-1M) — and every tier grew slower than in 2024. Spread over twelve months, that's roughly 1-2% per month (our derivation), which is far below the "5-10% monthly" numbers guru marketing throws around.
Benchmarks at a glance
Audience growth for brand accounts over 2025, by starting size (Socialinsider). Monthly figures are our estimates derived from the annual rates:
| Follower tier | Growth in 2025 | Monthly (est.) |
|---|---|---|
| 1-5K followers | 22% | ~1.7% / month |
| 5-10K followers | 20.29% | ~1.6% / month |
| 10-50K followers | 17.2% | ~1.3% / month |
| 50-100K followers | 13.62% | ~1.1% / month |
| 100K-1M followers | 11.25% | ~0.9% / month |
Every tier grew substantially slower in 2025 than in 2024 (small accounts were near 38% the year before). Individual creators can and do beat these brand-page averages — a breakout Reel can add months of growth in a week — but sustained double-digit monthly growth is the exception, not a realistic baseline. We haven't found a credible public dataset breaking follower growth out by industry, so ignore precise niche-by-niche growth tables.
The growth math most people get wrong
If an Instagram account has 10,000 followers, the measured ~1.3% monthly average for that tier is roughly 130 new followers a month — four or five a day. Even a strong account doubling the benchmark is adding under ten a day. That's the real texture of "solid" Instagram growth.
If someone is selling you a course promising "10K new followers per month" starting from zero, they're either lying or teaching something that isn't sustainable (like buying follows, running giveaways, or engagement pods that break TOS).
What actually moves follower growth
- Reels are the #1 lever. Reels are the main format Instagram distributes to non-followers, which makes them the primary discovery engine — and brands have been shifting output toward them (Socialinsider measured average Reels posting rising from 6 to 8 per month in 2025 while image posting fell).
- Niche consistency. The algorithm needs to know what your account is about to recommend you to the right audience. Account-theme drift kills growth.
- High completion rate on Reels. Reels that viewers watch to the end drive follower conversions. Hook hard, deliver fast, close with a reason to follow.
- Save-worthy carousel content. Carousels that people save signal the algorithm to push them to non-followers — and non-follower reach converts to follows.
- Profile optimization. A visitor who lands on your profile from a Reel decides in 3 seconds whether to follow. Bio, highlights, grid consistency — these matter.
Why growth slows with scale
Percentage growth always slows as follower count grows. This isn't a bug — it's math. Adding 500 followers when you have 1K is 50% growth. Adding 500 followers when you have 100K is 0.5% growth. Same effort, different percentage.
This is why comparing yourself to accounts with wildly different follower counts is pointless. A 10K account growing 5% monthly is doing the same work as a 100K account growing 0.5% monthly.
Follower count is a vanity metric (mostly)
Here's the uncomfortable truth: most Instagram creators track follower growth because it's the easiest number to see, not because it matters most. What matters more:
- Engaged follower percentage. Of your current followers, how many actually engage with you? 10K engaged > 100K ghost followers.
- Profile visits from Reels. Profile visits are the conversion step to follows.
- Link clicks. If your goal is to sell or drive traffic, link clicks matter more than follower count.
- DM conversion. Followers who DM you about your offer are the ones driving revenue.
How Heist helps with growth
Heist generates Reels scripts optimized for the first 2-3 seconds (where follower conversion happens). It also tracks which of your past posts drove the most profile visits (not just likes) and biases new content toward those patterns. Growth-focused, not vanity-focused.
