The Influence Issue is calculated by dividing the variety of citations within the JCR yr by the complete variety of articles revealed within the two earlier years.

Beneath is how Thomson calculated the 2008 impression issue for the journal Academy of Administration Overview:
Thus, the Influence Issue of 6.125 for the journal, Academy of Administration Overview for 2008 signifies that on common, the articles revealed on this journal prior to now two years have been cited about 6.125 occasions.
Components to Think about Whereas Consulting journal Influence Components:
- Publication Date:
- The impression issue is predicated on quotation frequency of articles from a journal of their first few years of publication.
