Why engagement rate matters
Follower count is vanity; engagement rate is what brands actually pay for. It shows how many of an account's followers really interact — the single number that decides sponsorship value. Whether you're pitching yourself or vetting an influencer, this is the figure to check.
How this calculator works
Enter a public @username. InstaGrab reads the likes and comments on the account's recent posts and its follower count — all public information — and computes the rate, plus average likes, average comments, and follower-to-following and likes-to-followers ratios.
Public numbers only
This tool never logs in and never touches follower lists or private data — it only uses the counts already visible on the public profile. Results are estimates; real engagement shifts with niche and content type.
