Andrew W Mellon Foundation: $450.4M Revenue, $654.0M Expenses

Andrew W Mellon Foundation pulls a D on the efficiency rubric. The composite of 42/100 reflects below-median performance on the bundle of factors — typically driven by thin operating reserves, volatile revenue, or outsized officer compensation relative to organizational size.

Annual revenue at Andrew W Mellon Foundation runs $450.4M (2023), placing it among the larger U.S. nonprofits in the IRS Form 990 dataset. On the financial-health factor, Andrew W Mellon Foundation runs thin — assets relative to annual spending fall below the cushion nonprofit-finance experts typically recommend.

Revenue has been roughly stable over the five-year filing window. The pattern is normal for established organizations operating in a mature program area. Current-officer compensation is not separately reported in the filing — typical for nonprofits where leadership is paid through a related entity (parent system, university, or foundation) rather than the filing organization itself, or for small organizations whose chief is a volunteer or board member. In the Education category, Andrew W Mellon Foundation sits alongside universities, K-12 systems, scholarship funds, and education-research organizations. Education-sector nonprofits often hold large endowments, which affects how the reserves-and-revenue figures should be read.
