Almost every question about growth is really a question about arithmetic: how many posts, reaching how many people, converting at what rate. Once those three numbers exist, the timeline follows.
This tool does that calculation and shows a range rather than a figure, because a single number reads as a promise and no honest projection is one.
The formula, in full
Nothing here is hidden. New followers per week is posts per week × average reach per post × the share of reached people who follow. The rest is multiplication by time.
- Posts per week — what you actually publish, not what you intend to.
- Average reach per post — from your own analytics, averaged over eight to twelve posts.
- Conversion — the share of reached people who follow. For most small accounts this sits between 0.3% and 1%.
- The range — the lower bound halves your conversion and the upper bound doubles it, because that is roughly how much a good or bad month varies.
If you do not know your conversion, start with 0.5% and correct it after a month of real data. A guessed input gives a guessed output, and the tool cannot know the difference.
Why it is a range and not a number
Three things move between one month and the next, and none of them is under your full control.
- One post travelling much further than usual can double a month on its own.
- Platform distribution changes without notice, and it changes for everyone at once.
- Seasonality is real in most niches: the same content performs differently in July and November.
That is also the honest answer to “how long until 10,000 followers”. You can compute it, and the answer is a window several months wide.
What the projection does not include
Two effects are deliberately left out, because including them would let the tool flatter you.
- Compounding. A larger audience raises baseline reach, so real growth curves bend upward. The projection stays linear, which makes it conservative rather than optimistic.
- Churn. Every account loses followers steadily, typically 1–3% a month. The projection shows gross additions, so subtract a little for net.
Using the output
| If the 90-day range is | It usually means |
|---|---|
| Under 100 | Reach is the constraint. More posts or a wider format, not a better profile. |
| 100 to 500 | Normal for a small consistent account. Keep the frequency and stop changing format. |
| 500 to 2,000 | The format is working. Repeat it rather than improving it. |
| Over 2,000 | Check the inputs — reach or conversion is probably an unusually good post rather than an average. |
Questions about this guide
Where do I find my average reach?
Instagram shows it as reach per post in professional insights, TikTok shows video views, YouTube shows impressions and views, and Facebook shows post reach on the page. Take the mean of your last eight to twelve posts rather than the best one, because a single outlier will distort the whole projection. If a post went unusually far, leave it out and note it separately.
Is a 0.5% conversion good or bad?
It is around the middle for a small account. Below roughly 0.3% usually means the posts are entertaining but not identifying — people watch and scroll on without ever looking at who made it. Above 1% usually means the content is tightly matched to a specific audience, which is a real advantage and worth protecting rather than broadening.
Why is my real growth slower than the projection?
The two most common reasons are churn, which the projection leaves out, and an average reach figure taken from a good month. Rerun it with the median of your posts instead of the mean, and subtract 1–3% a month for people leaving. If it is still far off, the gap is usually the conversion input rather than the reach one.
Can I use this to promise a client a follower count?
No, and the range is deliberately wide to make that awkward. The inputs come from a past that may not repeat, the tool leaves out both compounding and churn, and platform distribution can change in a week. Use it to set expectations about the shape of growth — slow start, faster later — rather than to commit to a figure.
