How this calculation works
This explicit interaction definition includes the four counts entered. Different reports may include different events or use different denominators; the same percentage is comparable only when its definitions match.
Engagement rate = (likes + comments + saves + shares) ÷ audience denominator × 100A worked example
100 likes, 10 comments, 5 saves and 5 shares give 120 interactions. Against a denominator of 2,000, the rate is 6%.
Good to know
Interactions can include several events from the same person. This is not a percentage of distinct people and need not stay below 100%.
Changing the denominator changes the story
A post with 120 interactions gives 6% when divided by 2,000 followers, but 12% when divided by 1,000 reached accounts. Those percentages can both be arithmetically correct while measuring different things.
A meaningful comparison therefore names its denominator. “Engagement rate by followers” and “engagement rate by reach” should not be combined as if they use one standard definition.
Interactions are events, not distinct people
Someone can like, comment, save and share the same post. Adding those actions counts events, not unique engaged people. The numerator may therefore be larger than the audience base, producing a rate above 100% without an arithmetic error.
Use the same included actions and reporting period for each comparison. This tool adds exactly the four entered fields; it does not infer profile visits, clicks, account-level totals or any missing analytics.
A few questions, answered
Does it fetch my Instagram account data?
No. You supply the counts, and the calculation runs in your browser.
Can I compare it with another analytics report?
Only after checking that the other report counts the same actions and uses the same denominator and period.
