ERC
Free engagement rate calculator - no signup, ever.
Free engagement rate calculator for Instagram, TikTok, YouTube, Facebook, LinkedIn & Twitter. Calculate your social media engagement rate instantly - no login, no signup. Compare vs latest benchmarks.
I built ERC because I got tired of the same frustrating loop: Google "engagement rate calculator," click a result, get hit with a login wall, then a paywall - just to divide two numbers.
Every tool I found either wanted my email, required connecting my social accounts, or hid basic features behind a subscription. All I needed was to plug in likes + comments + followers and see my rate compared to current benchmarks. That's it.
So I built exactly that. ERC is:
Actually free - no premium tier, no "unlock more features" upsell No signup - no email, no account, no OAuth. Just open it and use it. Private - all math happens in your browser. Zero data leaves your device. 6 platforms - Instagram, TikTok, YouTube, LinkedIn, Twitter, Facebook Cross-platform compare -* see rates side-by-side with per-platform benchmarks Mobile-friendly - works perfectly on phone since that's where most creators check stats I update the benchmarks regularly so "good" and "average" actually reflect what's happening in 2026, not outdated 2022 data that most blog posts still reference.
Built it as a solo dev with Astro + React, hosted on Cloudflare Pages. Fast, lightweight, no bloat.
Would love your feedback - is there a platform or metric you'd want added? Anything that would make this more useful for your workflow?
super clean and fast, got my rate in like two seconds with zero sign up. nice that it shows benchmarks right next to your number too.
