Impact Factor 2026

The Journal Citation Reports (JCR), containing citation data for the year 2025, was released on June 17, 2026.

The Impact Factor (IF) is an index measuring the influence and prestige of an academic journal; it is calculated annually by Clarivate Analytics and published in the Journal Citation Reports. It represents the average number of citations received in the most recent year by articles published in that specific journal during the preceding two-year period.

A high value suggests that the journal's content is widely cited by the scientific community and is therefore highly significant; however, this metric varies enormously across disciplines, meaning comparisons are valid only within the same field. It is important to note that the Impact Factor evaluates the journal as a whole and does not directly measure the quality of an individual article or researcher.

The complete list of Impact Factors (IF) is provided below.
