Academic Impact (H‑Index) Calculator Guidelines

You’ve got the research—now make it count.

Input Guidelines

  • Order matters: Enter citation counts in descending order.
  • Include all: Consider all peer-reviewed publications—articles, reviews, conference proceedings.
  • Adjust inputs: Use the 'Add Citation' button to input more entries as needed.

Best Practices

  • Exclude inflated citations: Some evaluators may ignore self-citations or inflated collaborative citations.
  • Understand contribution: Co-authored papers count fully toward each author’s H-Index.
  • Field-aware: Citation norms vary across disciplines. Compare H-Indices within similar fields and career stages.

Academic Impact (H‑Index) Calculator Description

What is the H-Index?

The H-Index (h) is a quantitative metric used to measure a researcher’s productivity and citation impact. It combines both the number of publications and the number of citations per publication.

Mathematical Definition

Given a set of n papers with citations c₁, c₂, ..., cₙ sorted in descending order,
h is the largest number such that cₕ ≥ h.

Why It Matters

  • Balances quantity and quality of research.
  • Used in academic hiring, funding, and promotion decisions.
  • Applicable across disciplines, though comparisons should be contextualized.

How to Use This Calculator

  1. Input your citation counts into the provided fields.
  2. Ensure values are in descending order.
  3. Use the 'Add Citation' button to enter your full list.
  4. The tool calculates your H-Index in real time.

Real-World Mini Case Studies

Case Study 1: Early Career Researcher

  • Publications: 7
  • Citations: [12, 10, 6, 3, 2, 1, 0]
  • H-Index: 3 (Three papers with ≥ 3 citations)

Case Study 2: Senior Researcher with One Landmark Paper

  • Publications: 5
  • Citations: [120, 4, 3, 2, 1]
  • H-Index: 2 (Only two papers have ≥ 2 citations)

Derivation in Code Logic

Sort citations in descending order.
Iterate through list:
    if citations[i] >= i+1 → continue
    else → return i as the H-Index

Frequently Asked Questions

The H-Index is a metric that reflects both the number of publications and the number of citations per publication, helping to evaluate a researcher’s overall impact.

Sort your publications in descending order of citations and find the largest number h such that you have h papers with at least h citations each.

Not typically. A high H-Index requires both numerous and well-cited papers. One highly cited paper alone will not increase the H-Index significantly.

Zero-cited papers do not contribute to the H-Index. If all your papers have zero citations, your H-Index will be 0.

Yes. Citations to co-authored papers are attributed fully to each co-author in H-Index calculations.

Periodically, especially after publishing new work or as citation counts change. Most researchers update it annually.

Edge cases include: (1) A single highly cited paper but low H-Index due to few other papers. (2) Large volume of publications with few citations. (3) Citations just below the threshold for increasing H. (4) Rapid career starts with early high-citation papers. (5) Citation inflation due to collaborative mega-authorship.

A good H-Index varies by field, but generally an H-Index above 10 for early-career researchers and above 20–40 for senior researchers is considered strong.
