1. What is Journal Impact Factor?

The Journal Impact Factor (IF) is a measure of the frequency with which the average article in a journal has been cited in a particular year. It is used to evaluate the relative importance of a journal within its field.

2. How Does the Calculator Work?

The calculator uses the standard Impact Factor formula:

\[ IF = \frac{\text{Citations in Year Y to Articles Published in Years Y-1 and Y-2}}{\text{Number of Articles Published in Years Y-1 and Y-2}} \]

Where:

\( Citations \) — Number of citations received in the current year
\( Articles \) — Number of articles published in the previous two years

Explanation: The Impact Factor represents the average number of citations per published article over a two-year period.

3. Importance of Impact Factor

Details: Impact Factors are widely used to compare journals within the same field. Higher impact factors generally indicate greater influence and prestige, though they should not be the sole criterion for evaluating research quality.

4. Using the Calculator

Tips: Enter the total number of citations received in the current year and the total number of articles published in the previous two years. Both values must be valid (citations ≥ 0, articles > 0).

5. Frequently Asked Questions (FAQ)

Q1: What is considered a good Impact Factor?
A: This varies by field. In general, IF > 10 is excellent, 3-10 is good, and <3 is average. Compare only within the same discipline.

Q2: How often is Impact Factor calculated?
A: Annually, as part of the Journal Citation Reports published by Clarivate Analytics.

Q3: What are limitations of Impact Factor?
A: It can be skewed by a few highly cited papers, doesn't account for article types, and varies widely between disciplines.

Q4: Does Impact Factor measure article quality?
A: Not directly. It measures citation frequency, which is only one proxy for influence and importance.

Q5: Are there alternatives to Impact Factor?
A: Yes, including CiteScore, SCImago Journal Rank, Eigenfactor, and altmetrics.
