What Instagram reach rate means

Reach rate is the percentage of your followers that a post reached. It shows how much of your audience Instagram is actually showing your content to.

Reach rate = accounts reached ÷ followers × 100

Example: 2,500 accounts reached on a 10,000-follower account = 25%.

Organic reach rate vs paid

Use only organic reach for this. Boosted posts add paid reach, which inflates the rate. Instagram insights split reach into followers and non-followers, which is useful for Reels.

Instagram story reach rate

Stories are mostly seen by existing followers, so story reach rate is a good measure of how engaged your core audience is. Use the reach of the first story frame.

What to do with the result

Track your average reach rate monthly. Then check how engaging posts were for people they reached with the engagement rate by reach calculator. For the difference between reach and impressions, see impressions vs reach.

Reach rate formula and example

Reach rate = reach ÷ followers × 100

Example: a post reaches 4,200 accounts and you have 20,000 followers. Reach rate = 4,200 ÷ 20,000 × 100 = 21%. Reach can go above 100% when a post is shared widely or shown to non-followers through Explore and Reels.
