I found slightly different numbers, but the exact details don't matter. If $12.5k is spent per child per year, and there are 20 children per classroom, that's $250k. Combining random sources (which use widely different divisions), I see numbers like: 60-90% instruction salary/benefit and related (higher numbers likely include non-teacher staff) 55-60% salaries 20-25% employee benefits (probably health insurance, which is really expensive in America no matter who pays for it) 5-20% capital/operations/contractors 10% administration 8% supplies 5-35% support (likely varies depending on what counts as "support") 0-5% debt 4% other
