Enter your citation counts for each paper and choose your citation format to calculate your H-Index, total citations, and G-Index. Paste one citation count per line in the Citations per Paper field, and this Citation Count Calculator breaks down your research impact across all key metrics. Also try the calculate Study Break.

The H-Index (Hirsch Index) is a metric that measures both the productivity and citation impact of a researcher. A researcher has an H-Index of h if h of their papers have each been cited at least h times. For example, an H-Index of 10 means 10 papers each have at least 10 citations. See also our Key-to-Word Ratio — Note-Taking Efficiency.
The calculator sorts your papers by citation count in descending order, then identifies the largest number h such that h papers each have at least h citations. Enter one citation count per paper per line and the tool handles all the ranking and comparison automatically.
The G-Index accounts for the cumulative citation performance of your top papers. It is the largest number g such that your top g papers together have received at least g² total citations. Unlike the H-Index, the G-Index gives extra credit to highly cited papers, making it more sensitive to citation outliers.
The H-Index provides a single number that captures both how many papers you have published and how impactful those papers are. It is widely used in academic evaluations, grant applications, tenure reviews, and for comparing researchers of similar career stage within the same field.

The H-Index is not suitable for comparing researchers across different disciplines, since citation norms vary widely by field. It also does not account for self-citations, career length, or publication types such as books and conference proceedings that may be underrepresented in citation databases.
You can retrieve your citation counts from Google Scholar, Web of Science, Scopus, or by using free tools like Publish or Perish. Search for your name or ORCID, view your publication list, and note the citation count for each paper, then enter those numbers here one per line.
No — the calculator automatically sorts your entries from highest to lowest before computing any index. If you prefer to keep your own ordering, select 'As Entered' in the Sort Citations dropdown, but note that descending order is required for correct H-Index and G-Index calculation.
A good H-Index depends on your career stage and field. Early-career researchers (under 5 years) typically have an H-Index between 2 and 5, mid-career researchers between 6 and 15, and senior researchers above 15. In highly active fields like physics or medicine, top researchers can exceed an H-Index of 50.
