How to 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.
Worked examples
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.
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.
