Engagement rate calculator
Paste a public profile from Instagram, TikTok, or Facebook and get its engagement rate — worked out from real recent posts, not an estimate.
How it works
- Pick a platform and paste a public username or profile link.
- We fetch the most recent 12 public posts and sum their likes and comments.
- Engagement rate is that average, divided by the profile's follower count.
Features
Real recent posts
Calculated from the profile's actual most recent public posts, not a guess.
Transparent sample size
Always shows exactly how many posts the number is based on.
Works across platforms
Instagram, TikTok, and Facebook, using the same formula for each.
Free, no sign-up
No account required for a limited number of checks per day.

Limitations
- Only public profiles can be sampled — private accounts are not supported.
- Based on the most recent 12 posts, not the account's full history.
- A brand-new account with very few posts will show a smaller, less representative sample.
See data methodology for the coverage rules that apply everywhere.
FAQ
- How is engagement rate calculated?
- We fetch the most recent 12 public posts, average their likes and comments, add those two averages together, and divide by the profile's follower count. The result is shown as a percentage, along with the exact sample size used.
- Does this work on private accounts?
- No — only public profiles can be sampled, the same public-data-only rule as the rest of SocialTrace.
- Why does my number differ from another tool?
- Different tools use different sample sizes and definitions of "engagement" (some include shares or saves, some use a different post count). Ours is transparent about exactly what it samples — there's no single industry-standard formula.
