Delphi Academy of Boston looks durable. The school holds 2.0 years of operating cushion, a healthy buffer. Revenue is highly concentrated at 92% tuition-dependent (peer median 88%): a soft admissions year would flow straight to the bottom line. Staff compensation runs 71% of expenses, about par for the peer cohort. Net assets are growing 16.3%/yr over three years; the cushion is being built, not drawn. NACUBO Composite Financial Index: 9.1 / 10, strong.
Delphi Academy of Boston reported $2.1M in revenue against $1.8M in expenses in fiscal year 2024, the most recent filing on record. Net assets stood at $3.6M — about 2.00x annual operating expense.
Operating margin landed at 16.4%, with 92.3% of revenue coming from tuition. Among same-size peers, that puts Delphi Academy of Boston at the p93 on operating margin.

Why “revenue scale” and not “endowment per student”: independent-school 990s don’t carry per-school enrollment, and NCES PSS coverage is partial, so we cannot divide endowment by a verified student count for every school. The bar above is each school’s latest reported total revenue. True endowment-per-student is scheduled for v1.1+ once Schedule D Part V parsing lands.
Peers are scored by similarity along three equal-weighted dimensions: size cohort (Form 990 employee count + max-revenue tier, a proxy for student enrollment, which the 990 does not carry), geographic region (eight-region grouping), and association overlap (NAIS, NBOA, regional councils). We rank the top 20 nearest peers and chart the first 12 by latest reported revenue. Values are the school’s most recently filed total revenue on IRS Form 990.
