Enter the h-index and the number of years since the first published paper into the Calculator. The calculator will evaluate the M-Index.

M-Index Formula

MI = h/n

Variables:

• MI is the M-Index ()
• h is the h-index
• n is the number of years since the first published paper

To calculate M-Index, divide the h-index by the number of years since the first published paper.

How to Calculate M-Index?

The following steps outline how to calculate the M-Index.

1. First, determine the h-index.
2. Next, determine the number of years since the first published paper.
3. Next, gather the formula from above = MI = h/n.
4. Finally, calculate the M-Index.
5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem :

Use the following variables as an example problem to test your knowledge.

h-index = 450

number of years since the first published paper = 800

What is the h-index?

The h-index is a metric for evaluating the cumulative impact of an author’s scholarly output and performance, measuring both the productivity and citation impact of the publications.

Why is the M-Index important for researchers?

The M-Index helps in adjusting the h-index for the time factor, providing a more accurate measure of a researcher’s impact relative to their career length. It can be particularly useful for comparing the performance of researchers at different career stages.

Can the M-Index decrease over time?

No, the M-Index cannot decrease as it is based on the h-index, which can only stay the same or increase as a researcher publishes more papers or receives more citations to their existing work.

How does the M-Index complement other bibliometric indicators?

The M-Index offers a time-adjusted evaluation of a researcher’s output, complementing other metrics like the h-index or the total number of citations by providing additional context regarding the researcher’s efficiency and consistency over their career.
