Let us put the method on the table before the results, because a ranking you cannot reproduce is just an opinion with decimal places.
The metric, stated plainly. Research cents per dollar equals research spending divided by total expenses — Form 990 Part IX, line 25, column A — expressed in cents. The second column uses total revenue, from Part I line 12, as the denominator instead. Research spending is the Part III program service expense that the organization itself labels as research, where it breaks out such a line; where it does not, we use the sum of Schedule I and Schedule F grants whose stated purpose is research. Every row tells you which of the two bases it used.
That second definition matters more than it sounds. Schedule I is the part of the return where a charity must itemize every grant of $5,000 or more, and beside each one it writes, in its own words, the purpose of that grant. The Internal Revenue Service does not supply a dropdown menu for that field. The charity types what the money was for. Reading those strings is the only way to separate a grant that funded a laboratory from a grant that funded a mammogram, and it is the step that nobody else in this category takes.
We deliberately built the metric to run cool rather than hot. Where a grant's stated purpose is genuinely ambiguous we say so in the row instead of quietly counting it. Where an organization runs research in-house rather than granting it out, we count the program line, but we do not then add the grants inside that line on top — that would double-count, and the number would flatter everyone. Where a filing is a Form 990-EZ, which carries no Schedule I at all, we note the reduced detail rather than pretending it is not there.
A few caveats belong here rather than buried at the bottom. Fiscal years differ between these organizations, and returns are filed months to years after the period they cover, so this is a snapshot rather than a scoreboard. The filings below span fiscal years ending December 2024 through June 2025 and were filed between July 2025 and May 2026. Any single year can be distorted by one large multi-year grant, a bequest, or a deficit — three organizations here spent more than they took in. Research share is one deliberately narrow dimension of merit, and it cannot see anything a filing does not disclose. Our organization list closed on September 9, 2026.
If the per-unit approach feels familiar, it is the same method we use when we rank foods by the best protein per dollar — pick one measurable thing, define it precisely, and apply it identically to every item.
Here is the whole table. Find the organization you were thinking of, then read its section for what the number actually means.
