Frequently Asked Questions

Q

How is the h-index calculated?

The h-index is the largest number h such that h publications have at least h citations each. Sort your papers by citation count descending, then find the row where the rank exceeds the citation count. If you have 8 papers and the top 5 each have 5+ citations, your h-index is 5.

  • Sort all papers by citation count from highest to lowest
  • Walk down the list: paper 1 needs 1+ citation, paper 2 needs 2+, etc.
  • Stop when citation count < rank position
  • That rank minus one is your h-index
  • Example: citations [45, 32, 18, 12, 8, 5, 3, 1] gives h-index = 5
RankCitationsRank <= Citations?h-index Status
145Yes (45 >= 1)h >= 1
232Yes (32 >= 2)h >= 2
318Yes (18 >= 3)h >= 3
412Yes (12 >= 4)h >= 4
58Yes (8 >= 5)h = 5

Q

What is the i10-index?

The i10-index is the number of publications with at least 10 citations. It was introduced by Google Scholar as a simple measure of productive, impactful research. A researcher with an i10-index of 15 has 15 papers that each received 10 or more citations.

  • Count papers with 10+ citations
  • Created by Google Scholar as a straightforward metric
  • Less sensitive to a single highly-cited outlier than h-index
  • Typical for early career: 0-5, mid-career: 5-20, senior: 20+
  • Complements h-index by focusing on consistent impact
Q

What is a good h-index for my career stage?

A new PhD typically has an h-index of 1-5. An established assistant professor might have 5-15. Full professors in active fields often range from 15-40+. Nobel laureates can exceed 100. These vary dramatically by discipline; biology h-indexes run higher than mathematics.

  • PhD student / postdoc: h-index 1-5
  • Assistant professor: h-index 5-15
  • Associate professor: h-index 10-25
  • Full professor: h-index 15-40+
  • Field leaders / Nobel laureates: h-index 50-100+

Q

How can I increase my h-index?

Focus on publishing in well-cited journals, collaborating with established researchers, and making your work accessible. Each new paper that reaches h+1 citations bumps your h-index by 1. Self-citation has diminishing returns and is frowned upon.

  • Publish in journals with high impact factor and visibility
  • Collaborate with well-cited researchers in your field
  • Make preprints available on arXiv, SSRN, or ResearchGate
  • Present at conferences to increase visibility
  • Each new paper needs h+1 citations to raise your h-index
Q

Why do citation metrics differ between Google Scholar, Scopus, and Web of Science?

Each database indexes different sources. Google Scholar includes preprints, conference papers, and books, giving higher counts. Scopus and Web of Science are more selective, covering only peer-reviewed journals. Your h-index may be 20 on Scholar but 15 on Scopus for the same work.

  • Google Scholar: broadest coverage, highest citation counts
  • Scopus: selective, covers 27,000+ journals and conferences
  • Web of Science: most selective, ~21,000 core journals
  • Scholar includes self-citations and non-peer-reviewed sources
  • Use the same database consistently for tracking progress

Example Calculations

1Early-Career Researcher (8 papers)

Inputs

Paper citations45, 32, 18, 12, 8, 5, 3, 1
Total papers8
Total citations124

Result

h-index5
i10-index4
Average per paper15.5

Sorted descending: 45, 32, 18, 12, 8, 5, 3, 1. Papers 1-5 each have >= 5 citations. Paper 6 has only 5 < 6 needed, so h-index = 5. Papers with 10+ citations: 45, 32, 18, 12 = i10-index of 4.

2Senior Researcher (5 papers)

Inputs

Paper citations120, 85, 42, 38, 15
Total papers5
Total citations300

Result

h-index5
i10-index5
Average per paper60.0

All 5 papers have >= 5 citations, so h-index = 5. All 5 have >= 10 citations, so i10-index = 5. The h-index is limited by publication count, not citation volume.

3Prolific Author (10 papers)

Inputs

Paper citations200, 150, 90, 60, 45, 30, 22, 15, 8, 2
Total papers10
Total citations622

Result

h-index8
i10-index8
Average per paper62.2

Papers 1-8 each have >= 8 citations (15 >= 8). Paper 9 has 8 < 9 needed, so h-index = 8. Papers with 10+ citations: first 8 papers = i10-index of 8.

Formulas Used

h-index

h = max(h) where h papers have >= h citations

The largest number h such that h publications each have at least h citations.

Where:

h= The h-index value
h papers= Number of papers sorted by citation count descending
h citations= Minimum citations for each of the top h papers

i10-index

i10 = count(papers where citations >= 10)

The number of publications that have received at least 10 citations each.

Where:

i10= The i10-index count
papers= All publications in the dataset
citations= Citation count for each individual paper

Average Citations per Paper

Average = Total Citations / Number of Papers

Mean number of citations received across all publications.

Where:

Average= Mean citations per publication
Total Citations= Sum of all citation counts
Number of Papers= Total publications in the dataset

Understanding Academic Citation Metrics

The h-index, proposed by physicist Jorge Hirsch in 2005, balances productivity and impact in a single number. It avoids rewarding researchers who publish many uncited papers or those with only one viral paper.

The i10-index complements the h-index by counting papers with 10+ citations, filtering out low-impact publications. Together with total citations and average per paper, these metrics give a rounded picture of research impact.

No single metric tells the whole story. Use this calculator to understand where you stand, but remember that citation counts vary dramatically by field, career stage, and publication venue.
