Stanford C-Score Calculator (Top 2% Scientist)

Are you in the Top 2% of Scientists?

This free tool calculates your Composite Score (C-Score) based on the methodology established by Ioannidis et al. (Stanford University/Elsevier). This metric is the global standard for ranking the top 2% of scientists across all fields.

Why use this tool? The official Elsevier database is updated annually and relies on Scopus data which may lag behind. This tool uses live Google Scholar data to give you an instant, up-to-date estimate of your standing for tenure, promotion, or grant applications.
