Yes — actively indexed in Scopus, coverage 1998–present (also 1991–1996), best quartile Q2, CiteScore 1.7.
Computational Complexity is Q2 in Mathematics (all) (rank 165 of 414), Q3 in Computational Mathematics (rank 131 of 212) and Q3 in Computational Theory and Mathematics (rank 130 of 203), by CiteScore 2025. It is ranked in 4 subject areas in all.
Computational Complexity is indexed in the Science Citation Index Expanded, so it may have a Journal Impact Factor in Clarivate's Journal Citation Reports. JCR is paid, so check it for the current value. The closest free measure is its Scopus CiteScore 1.7, which places it in quartile Q2 at the 60th percentile of its subject. Its SCImago Journal Rank (SJR, a free Scopus-based metric) is 0.537, quartile Q2, with an H-index of 45.
The publisher lists an article processing charge of about US$3,090 for open access (source: OpenAlex). Many journals also publish by the subscription route at no cost to the author, so confirm on the journal's own website.
Computational Complexity is published by Springer International Publishing. Its print ISSN is 1016-3328 and its online ISSN is 1420-8954.

Computational Complexity published 21 papers in 2025. 2026* is the year so far.
h-index, i10-index and 2-year mean citedness are open, licence-clear metrics from OpenAlex — not a proprietary impact factor. The subject rank counts only journals that OpenAlex has a figure for; it is not a Scopus or Clarivate ranking. Updated 2026-10-14.
In its latest 87 research articles (2021–2026), authors are most often from United States (23.5%), Israel (15.4%) and India (10.5%).
Countries are counted fractionally, so a paper by authors from two countries counts half to each.
Scopus status: Active. No retracted papers are recorded. The Problematic Paper Screener flags none of its papers. These are indicators to check, not findings against the journal.
Retractions from OpenAlex; flags from the Problematic Paper Screener (Cabanac, Labbé & Magazinov, CC BY), 2026-09-21 export. A flag marks a paper for a closer look; it is not a finding against the journal.
Index data is curated from public sources (Scopus, Web of Science, ABDC, FT50, UT Dallas, DOAJ). CiteScore and quartiles reflect the latest available Scopus release. Always verify a journal's current status on its official source before submitting.
