Public Schools Paid $21.5 Billion in Debt Interest in One Year — More Than a Third of What They Spent Building New Ones

A public school building gets money three ways: districts pay for repairs and new construction as they go, they borrow against future budgets and pay the loan back with interest, or they defer the work and let the building degrade.▸ NCES's own national ledger of school system finances shows the second channel is no longer a rounding error. In fiscal 2022 — the most recent year the Department of Education has closed the books on — the nation's public school systems paid $21,506,993,000 in interest on long-term debt. That is more than a third of the $60,422,731,000 they spent building or renovating school buildings that same year, and it went out the door before a single new roof, boiler, or classroom was paid for. Meanwhile, the Government Accountability Office's own nationally representative survey of school districts found 54% still need to update or replace multiple building systems — starting with heating and air conditioning, the single most common complaint, in an estimated 36,000 schools nationwide.

NCES's First Look report — compiled with the U.S. Census Bureau from every state's own fiscal filings — puts total FY2022 spending on public elementary and secondary education at $880,677,256,000.▸ Instruction takes the largest single share, $457.02 billion. Operations and maintenance — the function that keeps the lights on, the boilers running, and the roofs from leaking — gets $71.40 billion, a little over 9 cents of the current-spending dollar. Debt interest, $21.51 billion, is a smaller line than either, but it is money that buys nothing: no instruction, no repair, no new classroom. It is simply the cost of having borrowed before.

Spread across the 49,250,394 students NCES counted enrolled that school year, the arithmetic gets starker.▸ NCES's own per-pupil figure for operations and maintenance is $1,450. This article's own division of the same report's national totals puts new construction at roughly $1,227 per pupil and interest on debt at $437 per pupil — meaning the average public-school student is generating nearly a third as much in annual debt interest as the system spends physically maintaining the building they sit in.

The debt buys time, not repair.▸ GAO administered a nationally representative survey of school districts from August to October 2019 and found an estimated 54% need to update or replace multiple building systems or features in their schools. HVAC is the most common single complaint — 40.9% of districts need updates in at least half their schools, representing about 36,000 of the nation's roughly 98,000 public schools. Interior lighting (27.8%), roofing (27.7%), and safety and security systems (26.6%) aren't far behind. GAO's investigators, who visited 55 schools in six states, documented HVAC systems old enough to leak and damage flooring and ceiling tiles, in some cases forcing schools to adjust schedules.

GAO's district survey also found the funding for this work is uneven by design: in about half of districts nationwide, facilities money comes primarily from local property taxes, and high-poverty districts relied more commonly on state funding and less commonly on property taxes than low-poverty districts — meaning the districts with the least local tax base to borrow against are also the ones with the fewest options for financing the repairs GAO found they need.

Operations-and-maintenance money ultimately pays custodians, groundskeepers, and repair technicians — and BLS's own comparison of public and private school staffing shows public schools lean on them more, and pay for it: janitors and cleaners made up 4.0% of public-school employment versus 1.9% in private schools, and janitors in public schools earned $2,580 more a year on average than their private-school counterparts, while general maintenance and repair workers earned $5,150 more.▸ NCES's Digest of Education Statistics put total staff across the nation's public school systems at 6,795,470 in fall 2022 — a workforce whose maintenance corner is being asked to hold back deterioration that the district's own capital budget and GAO's own inspectors say is outrunning the money set aside for it.

Figures cover public elementary and secondary school systems nationwide. Interest, construction, and per-pupil calculations are drawn from NCES's FY2022 (school year 2021-22) First Look report, the most recent year NCES has closed the books on; building-condition figures come from GAO's 2019 district survey, published 2020, the most recent nationally representative facility-condition assessment of its kind; staffing figures compare BLS's May 2021 occupational data by school ownership type against NCES's fall 2022 staff count — the most recent year each agency has published.
