Follower Growth Rate
Social MediaAlso: Audience Growth Rate · Follower Growth
Quick definition
Follower growth rate is the percentage increase in an account's followers over a set period, calculated as new followers divided by the starting follower count. It measures how fast an audience is expanding, not how engaged or valuable that audience is.
Smaller accounts naturally post higher percentages. Track your own trend over consecutive periods rather than comparing raw percentage to a competitor's.
How it varies across Australia
Follower growth rate varies widely by platform, industry and starting size in Australia. Smaller accounts post larger percentage swings from small absolute changes, while established brand accounts grow slower but on a much bigger base. Compare your own trend over time rather than chasing a single external number.

Follower growth rate is the easiest social media number to celebrate and the easiest one to misuse. It's just new followers divided by starting followers, expressed as a percentage over a chosen period. A brand with 1,000 followers gaining 100 in a month has a 10 percent growth rate. A brand with 100,000 followers gaining the same 100 has a 0.1 percent growth rate. Same absolute gain, wildly different story.
That's the trap. Growth rate rewards small accounts and punishes established ones purely through maths, not performance. A large, mature brand account growing at 2 percent a month might be adding more real people than a small account growing at 20 percent.
The number also says nothing about who those followers are. Bought followers, contest entrants chasing a giveaway, and bot accounts all count the same as a genuinely interested customer. That's why follower growth rate needs to sit next to engagement rate and, ideally, some measure of on-platform conversion before anyone treats it as a health signal. Growth without engagement is a vanity metric with a nicer name.
Follower growth rate tells you an audience got bigger. It never tells you whether that audience is worth having.
How to calculate it
Follower growth rate = New followers ÷ Starting follower count x 100
Worked example. Started the month with 5,000 followers on Instagram. Ended with 5,350. New followers = 350. Growth rate = 350 ÷ 5,000 x 100 = 7 percent for the month.
The Australian context
Australian brand accounts tend to grow more slowly in raw numbers simply because the total addressable audience on any platform is smaller than the US or UK market. That means Australian benchmarks published by global platforms often overstate what's realistic locally.
Seasonal patterns also matter here. Growth often spikes around major Australian retail moments and dips over the December to January holiday period when engagement across most platforms softens. Read growth rate trends in that seasonal context rather than against a flat monthly target.

Common questions
What's a good follower growth rate on Instagram?
There's no universal good number because rate depends heavily on starting size. A small account might see double-digit percentage growth from a modest absolute gain, while a large brand account growing 1 to 2 percent a month could be adding far more real followers. Track your own trend over time.
Does buying followers improve follower growth rate?
It improves the number but not the account. Bought followers rarely engage, don't convert and often get purged in platform cleanups, causing a visible drop later. The growth rate spikes then reverses, and engagement rate falls in between.
Should follower growth rate be a KPI?
It can sit in a reporting dashboard but shouldn't be the primary target. Paired with engagement rate and some measure of conversion from social, it becomes useful context. Alone, it's easily gamed and doesn't reflect audience quality.
Why did my follower growth rate drop even though I'm posting more?
Posting frequency and follower growth aren't directly linked. Platform algorithm changes, content quality, seasonal dips and audience saturation on your existing content style all affect growth independently of how often you post.
