Horace Mann School: $134.4M Revenue, $117.5M Expenses

Horace Mann School pulls a D on the efficiency rubric. The composite of 49/100 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.

Horace Mann School is a large nonprofit by U.S. standards: $134.4M in 2023 revenue against $117.5M in expenses. Organizations in this revenue bracket usually run multiple programs with permanent staff and a meaningful endowment or reserve. Reserves are the limiting factor: Horace Mann School carries relatively few months of operating expenses on its balance sheet, which can leave an organization exposed if a major funding source pauses.

Five-year revenue is essentially flat — Horace Mann School's funding base appears stable but not growing. For mature organizations this is often the steady state; for younger ones it can signal a funding plateau worth diagnosing. Compensation for current officers and key employees runs $3.9M against $134.4M in revenue — within the band third-party charity raters typically consider reasonable for an organization of this size and complexity. This is an aggregate across all listed officers, not a single executive's salary. In the Education category, Horace Mann School 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.
