Abstract The variables investment, benefit, and yield were defined to study the influence of journal self‐citations on the impact factor. Investment represents the share of journal self‐citations that contribute to the impact factor. Benefit is defined as the ratio of journal impact factor including self‐citations to journal impact factor without self‐citations. Yield is the relationship between benefit and investment. I selected all journals included in 2008 in the Science Citation Index version of Journal Citation Reports. After deleting 482 records for reasons to be explained, I used a final set of 6,138 journals to study the distribution of the variables defined above. The distribution of benefit differed from the distribution of investment and yield. The top 20‐ranked journals were not the same for all three variables. The yield of self‐citations on the journal impact factor was, in general, very modest.
