Ever stared at your paystub and wondered where that chunk of change actually disappears to? Most people think it’s all going to some vague "government waste" or maybe just foreign aid. Honestly, the reality is way more interesting—and a bit more lopsided—than the memes on social media suggest.
The U.S. government spent roughly $7.01 trillion in fiscal year 2025. That’s a seven with twelve zeros. It’s a number so big it basically loses all meaning. To put it in perspective, that’s about 23% of the entire U.S. economy. If the U.S. was a giant household, we’d be the ones with the massive mortgage and a serious habit of spending more than we bring in. In 2025, the government only collected $5.23 trillion in revenue, leaving us with a $1.78 trillion deficit.
The Big Three: The "Unstoppable" Spending
When we talk about the breakdown of federal spending, we have to start with the stuff that’s on autopilot. This is called mandatory spending. Congress doesn't even vote on this every year; it just happens because of existing laws.
Social Security is the absolute heavyweight champion here. In 2026, it’s projected to eat up about 22% of the total budget. It’s simple math: more Baby Boomers are retiring, and they're living longer. Then you've got Medicare at about 15%. If you combine Social Security, Medicare, and other health programs like Medicaid, you're looking at nearly half of the entire federal budget.
It’s kinda wild when you think about it. Most of your tax dollars aren't going to "the government" in some abstract way; they're being redistributed to your grandparents or your future self.
The Interest Trap
There’s a new player in town that’s climbing the charts faster than a viral pop star. Net interest on the debt.
For a long time, interest was a footnote. But because the national debt is over $35 trillion and interest rates haven't stayed at zero, we are now spending roughly **$1 trillion a year** just on interest. That’s about 15% of all federal spending.
Think about that for a second. We are spending as much on interest—literally paying for past spending—as we are on Medicare. The Bipartisan Policy Center noted that in early fiscal year 2026, interest payments actually jumped by 14% in just a few months. It's a treadmill that's getting faster.
The Discretionary Slice: What Congress Actually Fights Over
This is the part you hear about on the news. Discretionary spending is the money Congress has to actually sit down and argue about every year. If they don't pass a bill, the government shuts down. This happened at the start of fiscal year 2026, leading to the longest shutdown in history before a continuing resolution was finally signed in November 2025.
Defense is the big dog in this category. For FY 2026, the budget request pushed defense spending toward $900 billion to $1 trillion. It accounts for more than half of all discretionary spending.
Then you have Non-Defense Discretionary (NDD). This is everything else.

- Education: Programs like Pell Grants and K-12 support.
- Transportation: Fixing bridges and keeping the FAA running.
- Veterans Benefits: Providing healthcare for those who served.
- International Affairs: This is the "foreign aid" everyone talks about, but in reality, it's usually only 1-2% of the total budget.
Why the 2026 Budget Looks Different
The 2026 fiscal year has seen some massive shifts. The current administration’s "skinny budget" proposed deep cuts to non-defense programs—we're talking 20-30% cuts in departments like Labor, Interior, and the EPA—while trying to shift that money over to the military and border security.
One of the most dramatic changes was a proposed 83% cut to the State Department’s base funding. That’s not a typo. The idea is to move away from international development and double down on domestic priorities like the "Golden Dome" missile defense system and nuclear modernization.
The Tariff Factor
On the revenue side, things got weird too. While we're talking about spending, you can't ignore how we pay for it. Customs duties (tariffs) skyrocketed in 2025 and 2026. In the first two months of FY 2026, tariff revenue was up nearly 290% compared to the previous year. That’s a lot of extra cash coming in, but it’s still not enough to cover the deficit.
Real-World Impact: What This Means for You
You might feel like this is all just "billionaire math," but it hits your wallet directly.
For instance, Medicare Part B premiums are hitting $202.90 a month in 2026. That’s up about 10% from 2025. Why? Because the cost of healthcare is rising faster than the rest of the economy, and the federal spending breakdown has to reflect that.
Also, when interest on the debt goes up, it puts upward pressure on all interest rates. Your mortgage, your car loan, your credit card—they’re all subtly tethered to how much the government has to pay its own creditors.

Actionable Insights for the Taxpayer
Understanding the breakdown of federal spending helps you cut through the political noise. Most "waste" people point to is a rounding error compared to the "Big Three" (Social Security, Medicare, and Defense).
If you want to stay informed or protect your finances, here are a few things you can actually do:
- Track the CBO reports: The Congressional Budget Office is non-partisan and provides the most "honest" look at where the ship is headed.
- Watch the Interest-to-GDP ratio: If net interest continues to consume more than 3% of our GDP, expect higher taxes or lower services down the road.
- Adjust your retirement expectations: With Social Security and Medicare taking up such a huge slice, keep an eye on "Means Testing" debates. If you’re a high earner, future benefits might look different than they do for today's seniors.
- Follow the Appropriations Bills: Don't just look at the President's budget (which is a wish list). Look at what the House and Senate actually pass. That’s where the rubber meets the road.
The federal budget is a reflection of a nation's priorities. Right now, those priorities are heavily weighted toward the past (debt interest) and the elderly (Social Security/Medicare), with a massive side of national security. Everything else—from NASA to cancer research to highway repairs—is fighting for the leftovers.
