Impact Factor (I.F.) is a reputation measurement of research journals that shows citations per publication during a period of time.
The Impact Factor is usually used to measure an academic journal reputation, popularity and for ranking.
How to Find the Impact Factor-
The general formula for the Impact Factor calculation is
Impact Factor = Number of Citations / Number of Publications
In a duration usually in two years.
For instance,
If you want to calculate the Impact Factor in year x.
Suppose a journal published 200 papers in year x-1. And numbers of citations to the papers are 400.
100 papers in the x-2 year. And the number of citations to the papers 200.
Then the Impact Factor of the journal will be.
I. F.= ( 400+200)/(200+100)= 2
JCR calculates in previous five years duration.
