# Engagement rate

Engagement rate is the share of your audience that interacted with a post: likes, comments, shares and saves divided by followers, reach or impressions, times 100. A post with 50 engagements and 2,000 followers has a 2.5% rate. Your result changes with the denominator, so name it in each report.

## Engagement rate formula

Choose one variant, write it down and keep it for every report you compare. Count the same actions each time. The examples below count likes, comments, shares and saves.

| Variant | Formula | Example (50 engagements) | Use it to |
| --- | --- | --- | --- |
| By followers | engagements / followers x 100 | 50 / 2,000 = 2.5% | Compare accounts |
| By reach | engagements / reach x 100 | 50 / 1,250 = 4.0% | Judge one post by who saw it |
| By impressions or views | engagements / impressions x 100 | 50 / 2,500 = 2.0% | Judge one post, repeat views included |
| Per post | engagements on one post / followers x 100 | 50 / 2,000 = 2.5% | Track posts against audience size |

## Worked example

A post gets 30 likes, 6 comments, 4 shares and 10 saves, 50 engagements in total.

- By followers (2,000): 50 / 2,000 x 100 = **2.5%**
- By reach (1,250): 50 / 1,250 x 100 = **4.0%**
- By impressions (2,500): 50 / 2,500 x 100 = **2.0%**

The post and the engagements stay the same. The three results differ because each one divides by a different audience.

## Why two tools report different rates

Two tools can disagree on the same post for two reasons. One counts link clicks and video plays as engagement and the other leaves them out. Or one divides by followers and the other by reach. Check both choices before you compare a number from one tool with a number from another.

## Questions

### Which denominator should I use?

Use reach or impressions to judge a single post, since they count who saw it. Use followers to compare accounts. Stay consistent across reports.

### Which actions count as engagement?

Common choices are likes, comments, shares and saves. Platforms and tools differ on clicks and video plays, so write down your definition.

### Can I compare my rate to another account's?

Yes, if both use the same denominator and the same actions. Otherwise compare your own trend over time.

## Engagement rate

Engagement rate is the share of an audience that interacted with your content, such as likes, comments, shares and saves. The result changes with the denominator you pick.

## Formula

Variants: (1) by followers = engagements / followers x 100; (2) by reach = engagements / reach x 100; (3) by impressions or views = engagements / impressions x 100; (4) per post = engagements on one post / followers x 100. Always state which denominator and which actions you counted.

## Example

Example: a post gets 30 likes, 6 comments, 4 shares and 10 saves (50 engagements). With 2,000 followers: 2.5%. With 1,250 reach: 4.0%. With 2,500 impressions: 2.0%.

## Which denominator should I use?

Use reach or impressions to judge a single post, since they count who saw it. Use followers to compare accounts. Stay consistent across reports.

## Which actions count as engagement?

Common choices are likes, comments, shares and saves. Platforms and tools differ on clicks and video plays, so write down your definition.

## Can I compare my rate to another account's?

Only if both use the same denominator and the same actions. Otherwise compare your own trend over time.
