Use this Facebook Reach Calculator to measure how much of your page audience your content reaches and how efficiently that reach turns into engagement. It is useful for comparing organic, paid, and viral distribution.
Reach rate shows the percentage of followers or audience size touched by your content. Higher reach with strong engagement means the content is distributing effectively.
A low reach rate can indicate weak distribution, poor timing, or content that does not trigger enough interaction.
With 60,000 followers, 28,000 reach, 76,000 impressions, and 1,900 engagements, reach rate is 46.67% and frequency is 2.71.
A reach rate above 50% is strong for many pages, while 20% to 50% can be acceptable depending on page size and content type.
Divide reach by followers and multiply by 100. This shows what percentage of your audience was reached.
Low reach may come from weak engagement, poor posting timing, overly promotional content, or limited distribution from the algorithm.
Create shareable posts, publish native video, encourage meaningful comments, and post when your audience is active.
Reach counts unique people, while impressions count total exposures. One person can create multiple impressions.
