The impact factor is a measure of the frequency with which the "average article" in a journal has been cited in a particular year or period. The annual JCR impact factor is a ratio between citations and recent citable items published. Thus, the impact factor of a journal is calculated by dividing the number of current year citations to the source items published in that journal during the previous two years.
The 2013 impact factor of a journal would be calculated as follows:
2013 impact factor = A/B.
where:
A = the number of times that all items published in that journal in 2011 and 2012 were cited by indexed publications during 2013.
B = the total number of "citable items" published by that journal in 2011 and 2012. ("Citable items" for this calculation are usually articles, reviews, proceedings, or notes; not editorials or letters to the editor).
The 2013 impact factor of a journal would be calculated as follows:
2013 impact factor = A/B.
where:
A = the number of times that all items published in that journal in 2011 and 2012 were cited by indexed publications during 2013.
B = the total number of "citable items" published by that journal in 2011 and 2012. ("Citable items" for this calculation are usually articles, reviews, proceedings, or notes; not editorials or letters to the editor).

The impact factor is used to measure the average article of a journal that how much it ranked in a specific time period by calculating how much time’s the article cited.
It is calculated by the formula A/B
A = how much time’s the article of the journal cited in a year.
B = how much times articles are citable.
