The number of times an average journal paper is mentioned over the course of a year is measured by the impact factor (IF). An Impact Factor is only given to journals that are included in the Science Citation Index Expanded (SCIE) and Social Sciences Citation Index (SSCI).


What is a good impact factor for scientific journals?

A journal's importance is determined by its impact factor, which counts the number of times individual articles are mentioned within a given year. Therefore, a journal's ranking is determined by its impact factor, which is a measure of how many citations or articles it has generated. If you wish to compare journals in the same subject area, IF is a useful tool.

How to measure a journal impact factor?

Here, we have given β€œ 5 ” journal metrics to understand the impact factor of the journal. They are,

Citesource metrics

1. Citesource metrics

It helps to assess the effect of journal citations. Calculated using information from Scopus, the biggest abstract and citation database of peer-reviewed literature, these metrics are free, thorough, transparent, and up-to-date.

2. SJR

SJR or SCImago Journal Rank, is relied on the concept of a transfer of prestige between journals via citation links.


SNIP or Source Normalized Impact per Paper, is a sophisticated metric that accounts for field-specific differences in citation practices.

4. JIF

JIF, or journal impact factor, is determined by Clarivate Analytics as the average of the total number of citations to a journal's publications over the previous two years divided by the total number of "citable" publications over the prior two years.

5. H- index

The H-index has been used to analyze higher-order collections of research papers, including journals, despite its origins as an author-level metric.

β€œA crucial step is choosing the ideal journal for your paper. Metrics are great tools to use as a roadmap for the process”

What is the impact factor 1?

According to an Impact Factor of 1.0, the average number of citations for publications published one or two years ago is one.

Lists of journals and their impact factor.

Hereby, we have given a list of journals and their impact factors. They are,

Impact factor of Scopus :

The impact factor of Scopus for the 2022–2023 journal is 0.166.

Impact factor of SCI :

The impact score (IS) 2021 of Science is 15.19

Impact factor of Springer :

It has an impact score (IS) of 0.49.

Impact factor of Elsevier :

It has an impact factor of 9.620.

Impact factor of UGC :

7.97 is UGC Impact Factor

What is an average impact factor?

A score of 3 is considered good, and an impact factor of 10 or above is often regarded as extraordinary. The average score is less than 1. As an illustration, in 2021, the highly esteemed publication Nature had an impact factor of 69.504.

What is the average β€œ5” year impact factor?

The average number of times journal articles published over the previous five years have been mentioned during the JCR year is known as the 5-year journal impact factor. It is computed by dividing the total number of publications published in the five years prior by the number of citations in the JCR year.

I want to know the impact factor of my selected journal

How impact factor is calculated?

The number of citations to sources published in a journal during the preceding two years is divided by the number of citations in the current year to get the publication's impact factor. The relevance of total citation frequencies can be better understood using the impact factor.

  • Total number of times its articles were cited during the two previous years
  • --------------------------------------------------------------------------------------------------- = A journal’s impact factor on a particular year
  • Total number of citable articles in the journal during those two years

For Example


How do you know if a journal is good?

A journal’s credibility is calculated by several factors. They are,

Where it is indexed?

  • Is the journal included or indexed in the major bibliographic databases for the field?
  • Is it possible to find the articles that the journal claims?

What is the history of its publishing?

  • Since when is the journal accessible?
  • Is the journal mission readily available for new journals? Who are the editorial board members?

Is it peer-reviewed?

  • How much time does the peer review procedure require?
  • Is this an appropriate amount of time for a quality evaluation?

What is it impact factor?

  • The average number of citations received over a two-year period is measured by the Impact Factor.
  • Has the journal's impact factor been calculated? If not, are there any other bibliometric measurements that can be used to determine whether or not this journal's articles are being read and cited by academics?

Is a higher impact factor better?

In most fields, an impact factor of 10 or higher is regarded as exceptional, a score of 3 as good, and a score of less than 1 as average. However, the 27 research disciplines listed in the Journal Citation Reports are the best way to interpret the impact factor in terms of the topic matter.

What is a low-impact factor journal?

A low-impact factor journal lacks the indicator of high quality that a high JIF offers. We have less information regarding a paper's quality if it is published in a low-impact journal rather than more information indicating that it has low quality.
