Cross-platform engagement rate calculator
Measure how strongly people respond to your content across Instagram, TikTok, YouTube, Facebook or X. Choose followers, reach or views as the denominator, use a real post sample, and see the exact interactions needed to reach your own target.
Your sample already clears the 3% target.
(9,500 interactions ÷ 10 posts) ÷ 25,000 audience or views × 100.
The formula is identical across the selected platforms. The general signal uses transparent, platform-neutral bands: under 1% developing, 1–3% steady, 3–6% strong and 6%+ exceptional. It is context, not a platform benchmark; format, audience size and whether you divide by followers, reach or views materially change the result.
How this is calculated
Add likes, comments, shares and saves across the sample, divide by the number of posts to get average interactions per post, then divide by followers, average reach or average views and multiply by 100. Choosing the denominator is a reporting decision: followers measures response against potential audience; reach or views measures response among people who actually received the content.
The result uses one transparent formula across platforms. The descriptive signal is deliberately general rather than pretending to be a live platform benchmark: under 1% developing, 1–3% steady, 3–6% strong and 6% or more exceptional. Compare like with like—same format, denominator, time window and sample size—and treat your own past performance as the most useful benchmark.

Common questions
What is the engagement rate formula?
For a multi-post sample: ((likes + comments + shares + saves) ÷ number of posts) ÷ denominator × 100. The denominator can be followers, average reach or average views; state which one you use whenever you report the rate.
Should I calculate engagement by followers, reach or views?
Use followers for a stable account-level comparison. Use reach or views when you want to judge how people who actually received a post responded. Rates from different denominators are not interchangeable, so compare only results calculated the same way.
How many posts should I include?
Ten recent posts is a useful starting sample, excluding pinned giveaways or obvious outliers if they are not representative. A larger consistent sample reduces the effect of one viral or unusually weak post.
