Short answer: “follow-back ratio” is not an Instagram-defined metric, and people use the phrase for two different calculations. The first is a general audience ratio: followers divided by following. The second is a follow-back rate: how many of the accounts you follow actually follow you back, divided by how many accounts you follow in total. Both are calculated from counts that a completed Followers and Following scan already gives you; neither requires a special app feature beyond accurate counts.
Two different things people call a “follow-back ratio”
- Followers-to-following ratio. Followers ÷ following. A profile with 10,000 followers and 500 following has a ratio of 20. This is sometimes used as a rough audience or influence signal: a high number means a profile has many followers relative to how many accounts it follows. It says nothing about who specifically follows back whom.
- Follow-back rate. Mutual follows ÷ total accounts you follow, as a percentage. If you follow 500 accounts and 300 of them follow you back, your follow-back rate is 60%. This is the number people usually want when they ask “what's my follow-back ratio,” since it answers how reciprocal your own following list is.
These two numbers can look very different for the same account, so decide which question you are actually asking before you calculate anything.
What counts as a “good” ratio?
There is no universal good ratio for either calculation; it depends heavily on the kind of account and why it exists. A creator account built around a large audience often has a high followers-to-following ratio by design. A personal account built around mutual friendships often has a high follow-back rate instead. Treat either number as context about how an account is used, not a score to optimize.
How to calculate either ratio from your own counts
- Get a completed full scan of both lists. A partial or sample result can undercount either list and skew the ratio. For the follow-back rate specifically, you need a completed scan of both Followers and Following to know which accounts actually overlap.
- For the audience ratio: divide your total followers by your total following.
- For the follow-back rate: divide the number of accounts you follow who also follow you back (sometimes labeled “mutual”) by your total following count, then multiply by 100.
- Keep the scan date with the result. Both counts change over time, so an old scan can give a stale ratio.
| You want to know | Formula | Where the numbers come from |
|---|---|---|
| General audience ratio | Followers ÷ Following | The follower and following totals from a completed scan. |
| Follow-back rate | (Mutual follows ÷ Following) × 100 | The mutual-follows count and total following from a completed scan of both lists. |
| Who specifically doesn't follow back | Not a ratio, a list | Accounts present in your Following list but absent from your Followers list in the same completed scan. |
How Lurke approaches this
Lurke does not display a single labeled “follow-back ratio” number. After a completed full scan of a public profile's Followers and Following lists, it shows total followers, total following, the mutual-follows count, and the specific accounts that profile follows but that don't follow back. Those are the exact figures both ratios above are built from, so you can calculate either one yourself from a completed scan rather than a partial preview. See the Lurke app overview or the Followers vs Following guide for how those two lists relate to each other.
When the answer is still unknown
- You only have a current follower/following count: it supports the audience ratio, but not the follow-back rate, which needs the overlap between both lists.
- Only one list is a completed full scan: wait for both Followers and Following to finish a full scan before calculating a follow-back rate, or the overlap count may be wrong.
- You want to know specifically who doesn't follow back: that is the not-following-back list itself, not a ratio; see the unfollower guide for the related two-scan method for people who left your Followers list entirely.
