In FY2025, the federal government will spend approximately $10.1 trillion. That's $10,100,000,000,000 โ a number so large it's essentially meaningless. So let's make it meaningful: if you're an American taxpayer, your share is roughly $63,296.
Where does all that money go? The answer might surprise you. Despite what cable news would have you believe, foreign aid is a rounding error. The real money goes to a handful of massive programs that run largely on autopilot.
The Big Picture: Every Dollar, Accounted For
Here's how the federal government spends every dollar it collects โ and then some, since it borrows roughly 25 cents of every dollar it spends:
๐ก The Autopilot Problem
Over 60% of federal spending is "mandatory" โ meaning it happens automatically without any annual vote from Congress. Social Security, Medicare, Medicaid, and interest on the debt are all on autopilot. Congress only votes on about one-third of total spending each year.
Medicare: The Biggest Line Item ($1.84T)
Medicare is now the single largest federal program, surpassing Social Security in FY2025. It costs $1.84 trillion โ 18 cents of every federal dollar. That's more than the entire defense budget. The program covers 67 million Americans over 65, but its costs have grown 75% since 2017, far outpacing inflation.
The Medicare trust fund is projected to be insolvent by 2031. Neither party has a plan to fix it. Republicans won't touch it because seniors vote. Democrats won't touch it because they want to expand it. The result: a $1.8 trillion program barreling toward insolvency while politicians look the other way.
Social Security: The Third Rail ($1.67T)
Social Security costs $1.67 trillion per year and covers 67 million beneficiaries. The average retired worker receives about $1,907 per month. It's the largest anti-poverty program in American history โ and it's going broke.
The Social Security trust fund is projected to be exhausted by 2033. After that, the program can only pay about 77% of promised benefits from incoming payroll taxes. That means a 23% cut to every retiree's check unless Congress acts. Given that Congress has known about this for 40 years and done nothing, don't hold your breath.
National Defense: $1.42 Trillion
The defense budget is $1.42 trillion when you include all defense-related spending (not just the Pentagon's base budget). This includes the Department of Defense, nuclear weapons programs at the Department of Energy, the VA, intelligence agencies, and other defense-related activities.
The U.S. spends more on defense than the next 10 countries combined. The Pentagon has never passed an audit. In 2023, it failed its sixth consecutive audit, with auditors unable to account for over 60% of its $3.8 trillion in assets. Let that sink in: the world's largest military can't tell you where its own money goes.
Net Interest: The Silent Budget Killer ($1.25T)
Here's the most alarming line item: $1.25 trillion in interest on the national debt. That's 12.4 cents of every dollar โ money that buys absolutely nothing. No roads, no schools, no defense. Just servicing past spending.
Interest costs have nearly tripled since 2017. At the current trajectory, interest will be the largest federal expenditure by 2030, surpassing even Social Security. We are literally borrowing money to pay interest on money we already borrowed.
๐จ The Interest Trap
In FY2025, the federal government will spend more on interest ($1.25T) than on national defense ($886B base Pentagon budget). Every percentage point increase in interest rates costs taxpayers roughly $300 billion per year.
What About Foreign Aid?
Americans consistently overestimate foreign aid spending. Polls show the average American thinks 25% of the budget goes to foreign aid. The real number? About 1% โ roughly $60 billion. It's a rounding error in a $10 trillion budget.
That doesn't mean foreign aid spending shouldn't be scrutinized โ every dollar should be. But if you're looking for the big money, it's in entitlements, defense, and interest. Everything else is a sideshow.
The Bottom Line
The federal budget is dominated by just four things: Medicare, Social Security, defense, and interest on the debt. Together, they consume 61% of all spending. Most of it is on autopilot. Congress barely controls a third of the budget through annual appropriations.
Any serious conversation about fiscal responsibility has to start with these programs. Cutting foreign aid, eliminating "waste," or defunding NPR makes for good political theater, but it doesn't move the needle on a $10 trillion budget. The math is the math.
