About this calculator
Calculate descriptive ratios from the counts you enter: engagements, link clicks and reposts per impression, replies as a share of engagements, and average impressions per post. These are arithmetic summaries only; they do not predict distribution, ranking or future performance.
Worked example
calculated with the default values below
Posts analysed 20 · Total impressions 200,000 · Total engagements 6,000 · Reposts 700 · Replies 900 · Link clicks 1,200 · Followers 15,000 Engagement rate by impressions 3.000 % · Average engagements per post as % of followers 2.000 % · Click-through rate 0.600 % · Repost rate 0.350 % · Reply share of engagements 15.0 % · Impressions per post 10,000 · Impressions per follower 0.67 x

Frequently asked questions
What happens when impressions or engagements are zero?
Rates that divide by zero are left undefined: impression-based rates are blank when impressions are zero, and reply share is blank when engagements are zero. Other results are direct ratios of the counts entered; they do not describe or predict X distribution or ranking.
