# What is maintainability index in code metrics?

Maintainability Index – Calculates an index value between 0 and 100 that represents the relative ease of maintaining the code. A high value means better maintainability. Color coded ratings can be used to quickly identify trouble spots in your code.

## What is maintainability index in software engineering?

Maintainability Index is a software metric which measures how maintainable (easy to support and change) the source code is. The maintainability index is calculated as a factored formula consisting of SLOC (Source Lines Of Code), Cyclomatic Complexity and Halstead volume.

## How is maintainability of code measured?

When investigating the maintainability of your code base, make sure to examine the number of code anomalies per thousand lines of code, i.e. the Findings Density. This gives you a measure for how often developers are confronted and hindered by code anomalies.

## How do you measure maintainability?

To measure the maintainability of an asset, you need to be able to quantify the amount of effort put into performing maintenance on that asset. While there are many methods to calculate the effort exerted, the most common way is simply by calculating the average time it takes to repair a piece of equipment.

## Which metrics can be used to evaluate maintainability?

Those are the four major dimensions on which one can measure maintainability.
• V is the average Halstead Volume per module.
• G is the average Cyclomatic Complexity per module.
• L is the average number of Source Lines of Code (SLOC) per module.
• C is the average number of comment lines per module.
