# Facebook engagement rate calculator

> Enter any public Facebook page. We read its latest posts and work out its engagement rate, its average reactions and comments, and its best posts, with nothing to type in by hand.

This is a free tool on the web page at https://www.manifoldmcp.com/free-tools/facebook-engagement-rate-calculator: 10 runs a day per visitor, no signup, run by a person in a browser. An agent can do the same job, and more, by connecting Manifold's MCP server at `https://mcp.manifoldmcp.com/mcp` (250 free credits a month). See [Facebook MCP server](https://www.manifoldmcp.com/mcp/facebook.md).

## How it works

1. Enter the page's name as it appears in its URL, like facebook.com/[name].
2. We read its followers and its latest posts, live.
3. See the engagement rate, the averages, and the three posts that did best.

## Benchmark against the pages you compete with

A rate means little alone. With Manifold connected, your agent reads your page and every competitor's the same way, lines the rates up, and checks the ads each page is running in Meta's ad library.

| | Here | In your agent with Manifold |
| --- | --- | --- |
| Accounts | One handle | You and every competitor, side by side |
| Posts | The latest | The latest, the all-time best, and the outliers |
| Why | The numbers | Transcripts and top comments of the posts that worked |
| Price | Free | 2 credits an account |

### Things to ask your agent

- Compare the engagement of our Facebook page with [rival one] and [rival two] over their latest posts.

- Is [competitor] running Meta ads right now? Show me the newest ones.

## Questions

### How is the Facebook engagement rate calculated?

For each of the latest posts, reactions plus comments, divided by the page's followers. The rate shown is the average across those posts. Facebook does not publish share counts, so shares are not in it.

### What do I enter?

The page's name as it appears in its address, the part after facebook.com/. It works for public business pages, not personal profiles.

### Is the Facebook engagement rate calculator free?

Yes. You get 10 pages a day here, with no signup. For more, connect Manifold to Claude, ChatGPT or Cursor: the free plan gives your agent 250 credits every month, with no card.
