You’ve heard the number: “The national debt is $38 trillion.” Politicians argue about it. News tickers flash it. But that figure is only half the story – and maybe not even the scary half.

If you look past the headline national debt, you’ll find a much larger number: roughly $107 trillion. That’s America’s total overall debt – the full mountain of promises, IOUs, and unfunded obligations that the U.S. has accumulated. And once you understand it, everything else about the federal budget – defense, Social Security, Medicare, even the interest you pay on your credit card – starts to make sense.

This article explains what that $107 trillion really means, where it comes from, and how it connects to the budget items you see every day.

The Two Numbers You Need to Know

Let’s start with a simple distinction.

1. The national debt (publicly traded)
Around $38.6 trillion as of early 2026. This is the cumulative total of all annual federal deficits. It’s the money the U.S. government has borrowed from investors, foreign governments (like Japan and China), the Federal Reserve, and itself (trust funds like Social Security). This is the number you see on most government websites and news headlines.

2. The total overall debt (the “real” debt)
Approximately $107 trillion – the figure displayed on the U.S. Debt Clock and similar trackers. This number adds three huge layers to the national debt:

Unfunded liabilities (about $73 trillion): The present value of future shortfalls in Social Security and Medicare over the next 75 years. These are promises the government has made but hasn’t set aside money to keep.

State and local government debt (~$3 trillion): Bonds issued by cities, counties, and states.

Agency and other federal debt (~$6 trillion): Debt from Fannie Mae, Freddie Mac, the Tennessee Valley Authority, and other government-sponsored entities.

When you add those to the $38.6 trillion national debt, you get a number somewhere between $107 trillion and $120 trillion, depending on the methodology.

Why Doesn’t Anyone Talk About the $107 Trillion?

Because the government doesn’t have to pay it back tomorrow. Unfunded liabilities are projections, not bills due next Tuesday. But they are real obligations. If Social Security and Medicare continue on their current paths, the trust funds will run out of money, and the government will either have to cut benefits, raise taxes dramatically, or borrow trillions more. Ignoring the $73 trillion doesn’t make it disappear.

Think of it like a household: the national debt is your credit card balance. The unfunded liabilities are your future mortgage payments, car loan, and children’s college tuition – money you will have to spend, even if you haven’t borrowed it yet.

The Four Biggest Items in the Federal Budget – And How They Connect to the $107 Trillion

Here’s where the picture gets clear. The U.S. government spends about $6.5–$7 trillion per year. The four largest line items (from a recent U.S. Debt Clock screenshot) are:

Category Annual Spending Medicare & Medicaid $1.95 trillion Social Security $1.62 trillion Net interest on the debt $0.996 trillion (~$1T) Defense / War$0.934 trillion (~$933B)

Now let’s tie each one back to the $107 trillion total debt.

1. Medicare & Medicaid ($1.95T) and Social Security ($1.62T) – The Drivers of the $73 Trillion Unfunded Liability

These two programs alone account for over $3.5 trillion in annual spending – more than defense and interest combined. They are also the source of nearly all of that $73 trillion in unfunded liabilities. Every year, the government collects less in payroll taxes than it pays out in benefits. The gap is covered by general revenue and borrowing. Over 75 years, the shortfall – in today’s dollars – is the $73 trillion number.

Without reforming these programs, the $107 trillion total debt will only grow, because the government is adding to its future promises every single year.

2. Net Interest on the Debt ($996B) – The Cost of Having Already Borrowed $38 Trillion

Interest is the price tag for the national debt (the $38.6 trillion part). It is not a choice. The government must pay bondholders. As interest rates have risen, net interest has now surpassed the defense budget. By 2036, the CBO projects it will reach over $2 trillion per year – more than either Social Security or Medicare.

Here’s the kicker: interest payments don’t buy anything. They don’t build a single ship, heal a single patient, or pave a single road. They are pure overhead on past borrowing. And because the national debt is part of the $107 trillion total debt, every dollar of interest pushes the total even higher.

3. Defense / War ($933B) – The Political Lightning Rod

The defense budget is the fourth largest item, but it’s the one that gets the most attention. As we discussed earlier, the Trump administration has proposed raising it to $1.5 trillion in FY2027 – a 42% increase. That would make defense the second largest category, behind only Medicare/Medicaid.

But here’s the reality check: even a $1.5 trillion defense budget is dwarfed by the $3.5 trillion spent on entitlements. And the $107 trillion total debt is driven almost entirely by those entitlements’ unfunded liabilities, not by the Pentagon. You could cut the defense budget to zero, and the $73 trillion Social Security/Medicare shortfall would remain virtually unchanged.

The Dollar’s Shrinking Value: The Hidden Tax That Makes the Debt Easier to Bear

One more piece of the puzzle: inflation. Since the Federal Reserve was created in 1913, the U.S. dollar has lost about 96% of its purchasing power. A dollar in 1913 bought what $30 buys today.

That sounds terrible, but it has a silver lining for the government: inflation erodes the real value of debt. When the government borrows $1 trillion today and pays it back with dollars that are worth 2–3% less each year, the real burden shrinks. That’s why the government doesn’t panic about the $38 trillion national debt – it can inflate some of it away.

The flip side is that inflation hurts savers, workers, and anyone on a fixed income. It’s a hidden tax that transfers wealth from creditors to debtors. In the case of the U.S. government, the biggest debtor is also the one printing the money.

So What Does the $107 Trillion Mean for You?

It means future tax increases or benefit cuts are almost certain. The math does not work. You cannot have $73 trillion in unfunded promises without either raising taxes (on income, gas, carbon, wealth – something) or reducing what Social Security and Medicare pay out.

It means interest on the debt will crowd out other spending. As net interest rises to $2 trillion per year, there will be less money for defense, infrastructure, education, and everything else. Congress will have to choose.

It means the “defense vs. welfare” debate is a sideshow. Yes, you could cut all welfare programs (food stamps, housing, etc.) – but those total about $600 billion, not the $3.5 trillion of entitlements. The real choice is between cutting Social Security/Medicare, raising taxes massively, or accepting that the $107 trillion total debt will keep growing until a crisis hits.

A Final Reality Check

No official proposal has ever tried to pay down the $107 trillion total debt. It’s not even a formal target. But understanding it changes how you read the news. When you hear “Congress raised the debt ceiling,” you’ll know they’re only talking about the $38 trillion national debt. When you hear “Social Security is solvent for 10 more years,” you’ll know that’s just the trust fund accounting – the unfunded liability is already sitting there like a glacier.

The $107 trillion is not a doomsday prediction. It’s a scorecard. And right now, the score is not in America’s favor.
