What it shows

  • Engagement rate

    Likes plus comments against followers, worked out per post and averaged over the period. The formula is on the card.

  • ERR by views

    Interactions against views across video posts. Labelled "by views", because reach-based ERR is private to the owner.

  • periods

    Week, 2 weeks and Month. Older posts load quietly in the background, so every period has full data.

  • numbers per period

    Posts, engagement, likes, comments, views, average per post, ER, ERR, posts per week and likes per comment.

  • Top posts

    A ranked list with a heat cell showing how each post compares with the best one, and a link to it.

  • PDF and Excel

    A print-ready report page with a chart and a per-post table, or a styled .xlsx file for your own formulas.

How the engagement rate is calculated

ER = (likes + comments) ÷ followers × 100, worked out for each post and averaged over the period. Posts whose owner hides the like count are left out instead of guessed. Other tools may divide by reach or by views, so their numbers can differ; Likelens shows its formula on every card.

Reach, saves and shares are private: only the account owner sees them in Instagram's own insights. Likelens doesn't invent them. What it can measure honestly from public data is ERR by views, interactions against video views, and it says so on the card.

Private by design

  • No extra login

    You stay in your normal signed-in browser session. No API key, no account with us.

  • No servers of its own

    Everything is calculated in your browser. Your data is not collected or sent anywhere.

  • Few permissions

    Storage, for your period and settings. instagram.com, to read the public profile you have open. Two image hosts, only to put the avatar and thumbnails into an exported report.

Questions

How do I check the engagement rate of an Instagram account?

Add Likelens to Chrome and open the public profile on instagram.com. The panel shows its ER for the last week, two weeks or month.

How is Instagram engagement rate calculated?

Likelens uses (likes + comments) ÷ followers × 100 for each post and averages it over the period. Posts with hidden likes are left out.

Why is the ER different from another calculator?

Tools divide differently: by followers, by reach or by views, and over different sets of posts. Likelens divides by followers and shows the formula on the card.

Can I see reach or shares of someone else's account?

No. Reach, saves and shares are visible only to the account owner. Likelens shows public numbers only and never makes them up.

Does it work on private accounts?

No. A private profile shows an empty state instead of numbers.

Can I export the stats to PDF or Excel?

Yes. Export opens a report page you can save as PDF from the print dialog, or downloads a styled .xlsx file with every post.

Do I need to log in? Is my data sent anywhere?

You use your normal signed-in session on instagram.com; there is no extra login. The numbers are calculated in your browser and are not sent anywhere.
