# Instagram engagement rate calculator: run it free, or from your agent

Engagement rate per post, average and median, from followers plus the likes and comments of recent posts.

## Prompt

Use looot to work out the Instagram engagement rate of these accounts: [usernames]. 1. Set up https://looot.ai/skill.md. 2. Find an Instagram profile endpoint in the catalog and check its price. 3. For each account read the followers and the likes and comments of the recent posts it returns. 4. Return a table of account, followers, average likes, average comments and engagement rate, and the total cost.

## What it needs

Follower count, and likes and comments of recent posts

## What comes back

- average engagement rate
- median engagement rate
- engagement rate per post
- average likes
- average comments
- best and worst post

## Endpoints and providers

None. The tool on the web page runs in the browser and calls no endpoint.

## What it costs

Nothing. The tool on the web page runs in the visitor's browser: no account, no API call and no limit per hour. The prompt above runs the same job from your own looot account with current data, billed per call.

## Vet an influencer

A large follower count with few likes per post is worth a second look.

## Price a sponsorship

Compare engagement as well as followers before you agree on a fee.

## Find your best posts

See which of your recent posts beat your own average.

## Check a list

Give your agent a list of accounts and get the rate for each one.

## How do you calculate Instagram engagement rate?

Add the likes and comments of a post, divide by the follower count and multiply by 100. The calculator does that for each post you enter, then takes the average and the median.

## What is a good engagement rate on Instagram?

There is no single number. Rates fall as accounts grow and differ by niche, so compare an account with others of a similar size in the same niche.

## Why show the median as well as the average?

One viral post pulls the average up. The median is the middle post, so it shows what a typical post does.

## Should I count saves, shares and views?

This calculator uses likes and comments, which anyone can see on a public post. Saves and shares are only visible to the account owner.

## Where do I get the numbers?

Followers come from the profile, and likes and comments from each post. The Instagram profile viewer linked below shows the follower count of any public account.

## How many posts should I enter?

Use the most recent posts, skipping the newest one if it is only hours old. More posts give a steadier average.

## Is it free?

Yes. It runs in your browser with no account, no limit and no API call.
