7.00%

Formula: (likes + comments + shares + saves) ÷ reach × 100
140 engagements ÷ 2000 reach × 100 = 7.00%
Use metrics from the same reporting period and scope. This custom formula is not a platform-defined score. Reach, impressions, and followers produce different rates; compare like with like. Repeated engagement can produce rates above 100%. No universal “good” rate is implied.

How to use this tool

Enter likes, comments, shares, and saves from the same post or reporting scope.
Choose reach, impressions, or followers and enter its count from the same scope.
Compare only results that use the same metric definition and denominator.

A worked example

100 likes + 20 comments + 10 shares + 10 saves = 140 engagements. With reach of 2,000, the rate is 140 ÷ 2,000 × 100 = 7%.

Use the prefilled example to explore the output, then replace it with your own inputs. Review dates and responsibilities with your team before using the result.

Common questions

What is a good engagement rate?

There is no universal threshold here. Platform, format, audience, denominator, and objectives affect interpretation. This calculator uses an explicit custom formula rather than claiming a platform’s native definition.
