8,000 reach on 20,000 followers
8,000 ÷ 20,000 × 100 = a 40% reach rate for that post.
Reach rate calculator
Calculate your reach rate from a post’s reach and your follower count: reach rate = reach ÷ followers × 100. A real, simple, hand-verified formula — enter your own numbers from your platform’s analytics and get the percentage instantly, entirely in your browser. Reach rate measures how much of your existing audience a post actually reached, distinct from engagement rate.

Formula
Reach rate = reach ÷ followers × 100
What is reach rate?
Reach rate is the share of your followers a post reached, as a percentage: reach divided by followers, times 100. Reach counts separate people, so it shows how far a post travelled through your audience, apart from how many of them interacted. It can pass 100% when shares and recommendations show the post to people who do not follow you.
How does reach rate differ from impressions and engagement rate?
Three rates, three questions. Use the one that matches what you want to know:
| Rate | Formula | What it tells you |
|---|---|---|
| Reach rate | Reach ÷ followers × 100 | How much of your audience a post reached |
| Impression rate | Impressions ÷ followers × 100 | How often it was shown, counting repeat views |
| Engagement rate | (likes + comments + shares) ÷ (followers × posts) × 100 | How many people interacted with it |
Work out the third with the engagement rate calculator, and the share of viewers who watched a video with the video view rate calculator.
Where do you find reach on each platform?
In each post’s insights, under the platform’s own name. Not every platform reports unique reach:
| Platform | Reach is reported as |
|---|---|
| X (Twitter) | Not reported; use impressions or views |
| Members reached | |
| Viewers | |
| Facebook Pages | Viewers |
| TikTok | Not reported; use impressions or views |
| YouTube | Not reported; use impressions or views |
| Threads | Not reported; use impressions or views |
| Not reported; use impressions or views | |
| Bluesky | Not reported; use impressions or views |
| Telegram | Not reported; use impressions or views |
| Google Business Profile | Not reported; use impressions or views |

How do you use the reach rate calculator?
- Enter your post reach. Use the unique-accounts-reached figure from your platform’s analytics.
- Enter your follower count. Use your total follower count at the time of the post.
- Read the reach rate. See reach divided by followers, times 100, shown as a percentage.
- Compare across posts. Recalculate for other posts to see which reached relatively more of your audience.
What does it look like in practice?
Reach can exceed 100% of followers
A post reaching 25,000 accounts on a 20,000-follower account gives a 125% reach rate, since shares and algorithmic distribution can reach non-followers too.
What raises a post’s reach rate?
Posting when your followers are active, in the formats each platform favours, and content people share. Compare a few posts on one platform rather than against another network’s numbers, since each counts reach its own way. Start from the best time to post for each platform.
Reach rate calculator FAQ
- Can reach rate go above 100%?
- Yes — if a post is shared or algorithmically shown beyond your existing followers, reach can exceed your follower count, giving a rate above 100%.
- Is reach rate the same as engagement rate?
- No — reach rate measures how many accounts saw the post; engagement rate measures how many of them interacted with it. They answer different questions.
- What is a good reach rate?
- It varies a lot by platform and algorithm, so this tool reports your raw calculated rate without an invented universal benchmark.
- Where do I find my post’s reach number?
- In the native analytics for whatever platform you posted on — this calculator only applies the formula to the number you enter from there.
- Does this calculator store my numbers?
- No — the calculation happens entirely in your browser as you type, and nothing is uploaded or saved.
- Should I use reach or impressions for this calculation?
- Reach specifically — unique accounts reached, not total impressions, which can count the same account more than once.
- Which platforms report reach?
- Not all of them. Some report unique reach for a post; others report only impressions or views, which count repeat showings. The table on this page lists each platform and its own name for the figure.
