Calculate social media reach rate, reached audience, unreached audience, impressions per reached user, and campaign reach. Use this calculator for Instagram, TikTok, YouTube, Facebook, Pinterest, LinkedIn, X, influencer campaigns, and general social media reporting.
People reached:
Enter the number of unique users who saw the post, video, pin, page, or campaign.
Total audience size:
Enter your followers, subscribers, page likes, target audience, or campaign audience size.
Impressions:
Enter total impressions to estimate average frequency, or how many times each reached person saw the content.
A reach calculator helps measure how much of your audience actually saw your social media content. It can be useful for comparing posts, checking campaign visibility, reviewing influencer reports, and planning content performance.
Reach is especially useful when paired with engagement rate, impressions, click-through rate, and conversion rate.
The basic reach rate formula is:
Reach Rate = People Reached ÷ Total Audience Size × 100
Reach is the number of unique people who saw your social media content. If one person sees the same post multiple times, they usually count as one reached user.
Divide people reached by total audience size, then multiply by 100. For example, 5,000 people reached from 20,000 followers equals a 25% reach rate.
Reach measures unique people. Impressions measure total times content was displayed. Impressions are usually equal to or higher than reach.
A good reach rate depends on the platform, account size, content type, niche, and whether the content is organic or paid. As a general estimate, 25% to 50% is strong, while 50% or more is very high.
