Top journals with high Impact Factor


Impact Factor (IF) or often called journal impact factor (JIF) is an index provided by an analytics company named Clarivate. 
The impact factor is calculated by dividing the number of times the articles are cited in the last two years by the total number of publications in those two years.
Total Citations in 2020 and 2021 = 500
Total Number of Publications in 2020 and 2021 = 100
Impact Factor of the Journal in 2022 = 500/100 = 5
