Reach rate:
The calculator divides total reach by followers to estimate how much of your audience size the content reached.
Frequency:
The calculator divides impressions by reach to estimate average repeat exposure.
Discovery:
The calculator compares follower reach and non-follower reach to show how much reach came from outside your current followers.
An Instagram reach calculator helps creators, brands, influencers, and social media managers understand content visibility and discovery.
It is useful for Instagram reports, Reels analysis, sponsored posts, campaign reviews, media kits, and content strategy planning.
Common Instagram reach formulas include:
Instagram Reach Rate = Total Reach ÷ Followers × 100
Instagram reach is the number of unique accounts that saw your content. It is different from impressions, which can include multiple views from the same account.
Divide total reach by followers, then multiply by 100. For example, 18,000 reach from 50,000 followers equals a 36% reach rate.
Frequency estimates how many times each reached account saw the content on average. It is calculated by dividing impressions by reach.
Non-follower reach shows how much of your visibility came from people who do not already follow you. It can be useful for measuring discovery and audience growth potential.
