# Ratio Comparison Node

The **Ratio Comparison** node divides one number about a post's author by another, and compares the result against a value you set. Use it for things a single threshold can't express: "at least twice as many followers as accounts followed", rather than "at least 500 followers".

You'll find it in the editor's Rules menu (the filter icon), on the **Basic** tab under **Attribute**.

## Fields

The node reads left to right, like a sentence:

1. The attribute on top of the division.
2. ÷ the attribute underneath.
3. An operator: **at least**, **at most**, **above** or **below**.
4. The value to compare the ratio against. It can be a decimal, such as `0.5` or `2.5`.

Only numeric attributes can be divided, so the attribute lists are shorter than in Attribute Comparison:

- **Account Age (days)**
- **User Followers**
- **User Following**
- **User Post Count**

A new node starts as **User Followers** ÷ **User Following** **at least** 2.

## Things to know

- **Nothing matches when the bottom value is zero.** An account that follows nobody has a following count of 0, so there's no meaningful ratio. The post is excluded, not treated as infinite.
- **There's no "is exactly".** A ratio is a decimal, so an exact match would almost never happen.

## Examples

- **Skip follow-for-follow accounts**: User Followers ÷ User Following **at least** 0.5.
- **Established posters**: User Post Count ÷ Account Age (days) **at least** 1, for accounts that average at least one post a day.
- **Accounts people seek out**: User Followers ÷ User Following **at least** 10.

Combine it with your other rules in a Logic node, the same as any other condition. Use [Debugging a Post](https://www.graze.social/docs/debugging-a-post) to check how a particular account's post fares.
