Even before Congress passed President Donald Trump\u2019s major tax and domestic policy legislation, the federal government was on track to spend $1.9 trillion more this fiscal year than it collected in revenue, according to the nonpartisan Congressional Budget Office (CBO). The CBO now projects<\/a> that the recently signed \u201cmegabill<\/a>,\u201d as it\u2019s been dubbed, will add nearly $3.4 trillion more in deficit spending over the next decade.<\/p>\n\n\n\n

When the government runs a deficit \u2013 that is, when it spends more in a year than it receives in revenue \u2013 it makes up the difference by borrowing. That means annual budget deficits add to the national debt, which was almost $37 trillion as of Aug. 8. While the \u201cmegabill\u201d raised the federal debt limit by $5 trillion to $41.1 trillion, that\u2019s not likely to be enough: The CBO estimates<\/a> that the nation\u2019s debt will exceed $52 trillion by the end of fiscal 2035.<\/p>\n\n\n\n

How we did this<\/summary>\n

Pew Research Center conducted this analysis to provide an update on the national debt following the passage of a major Republican tax and spending law.<\/p>\n\n\n\n

Most of this analysis deals with \u201ctotal public debt outstanding,\u201d which stood at just under $37.0 trillion at the time of publication. Of that amount, about $115.0 billion is not subject to the statutory debt limit<\/a>. Most of that represents the accounting treatment of certain Treasury securities sold at a discount to their face value ($110.4 billion) and debt issued by the Federal Financing Bank<\/a> ($4.1 billion).<\/p>\n\n\n\n

The Treasury Department makes available extensive information on U.S. public debt, from detailed analyses of its composition and ownership<\/a> to the exact daily balance, calculated down to the penny<\/a>. For this analysis, we used data from several of these publications and datasets, but our primary source was the department\u2019s Monthly Statement of the Public Debt<\/a>.<\/p>\n\n\n\n

Data on gross domestic product came from the federal Bureau of Economic Analysis<\/a>. Figures on interest payments on the debt and overall federal spending came from the Office of Management and Budget<\/a>. FRED, a database of economic and financial data<\/a> maintained by the Federal Reserve Bank of St. Louis, was our source for historical data on the Fed\u2019s interest-rate decisions.<\/p>\n<\/details>\n\n\n\n

Why does the U.S. have a debt limit, anyway?<\/strong><\/summary>\n

Aside from Denmark<\/a>, the United States is the only country with a law setting a specific monetary limit on its national debt. (Australia enacted such a limit during the 2007-09 global financial crisis, only to repeal it<\/a> a few years later. In 2023, Kenya changed its numerical limit to one expressed as a share of gross domestic product<\/a>, or GDP.)<\/p>\n\n\n\n

Other countries also have debt caps linked to GDP, meaning that as their economies grow, the monetary value of the debt limit rises as well. European Union member countries, for example, are supposed to keep their public debts to no more than 60% of GDP, though in practice many countries are well in excess<\/a> of that limit and enforcement has been inconsistent.<\/p>\n\n\n\n

The U.S. has had public debt for longer than it\u2019s been a country<\/a>, but it managed to get along without a debt limit for more than a century and a half. The standard practice was for Congress to authorize specific bond issues for specific purposes \u2013 $11.25 million to fund the Louisiana Purchase<\/a>, $500 million to finance the Civil War<\/a>, $130 million to build the Panama Canal<\/a>, and so forth. Along with the size of the bond issue, Congress might also specify the bonds\u2019 denominations, interest rates, maturity dates, early redemption rules, and other terms and conditions.<\/p>\n\n\n\n

But when the U.S. entered World War I in 1917, it was confronted with the need to borrow unprecedented sums of money. By the time the Treaty of Versailles formally ended the war in 1919, the U.S. had sold $21.5 billion in bonds<\/a>, along with $3.45 billion in short-term certificates, with varying lengths, interest rates, redemption rules and tax treatments. Administering and paying down that debt proved to be too complex for Congress to micromanage.<\/p>\n\n\n\n

The laws authorizing the WWI bonds \u2013 primarily what became known as the Second Liberty Bond Act \u2013 originally spelled out in some detail the terms and conditions of each bond issue. But throughout the 1920s and 1930s, as the various bond issues approached maturity and had to be either paid off or refinanced, Congress gave the Treasury Secretary more and more discretion<\/a> to issue new and different types of debt securities under terms the secretary thought best.<\/p>\n\n\n\n

Gradually, the specifications in the Second Liberty Bond Act (which in amended form came to govern most government borrowing) were replaced by broad caps. In 1939, the few remaining limits were replaced by an overall $45 billion cap that covered nearly all public debt \u2013 the birth of the statutory debt limit as we know it today.<\/p>\n<\/details>\n\n\n\n

With all that in mind, here are facts and figures about the national debt. For more about the statutory debt limit, read \u201cWhy does the U.S. have a debt limit, anyway?<\/a>\u201d above.<\/p>\n\n\n\n

The nation\u2019s debt is considerably bigger than its entire economy.<\/strong> Gross domestic product (GDP), the sum of all goods and services produced by the U.S. economy, was $30.3 trillion at the end of the second quarter of 2025 (June 30), according to the latest estimate<\/a> by the Bureau of Economic Analysis (BEA). That means the debt, which stood at $36.2 trillion at the end of the second quarter, was 119.4% of GDP.<\/p>\n\n\n\n

\"A<\/a><\/figure>\n\n\n\n

The debt-to-GDP ratio is a useful metric for analyzing the debt over long time spans because it puts the debt into the context of the overall economy. Looking at it this way, debt as a share of GDP has gone through three main growth phases in recent decades. These phases have corresponded with periods when the federal government ran large deficits: the Reagan-Bush years<\/a> of the 1980s and early 1990s; the 2008 financial crisis and subsequent Great Recession<\/a>; and the COVID-19 pandemic, when federal debt spiked to an all-time high of 132.8% of GDP in the second quarter of 2020, according to our analysis.<\/p>\n\n\n\n

Private investors are the biggest holders of U.S. debt.<\/strong> Investors own about two-thirds of the national debt, or $24.4 trillion as of March 2025, the latest figures available. The rest is held in various federal trust funds and retirement programs ($7.3 trillion, or 20.1%) or by the Federal Reserve System ($4.6 trillion, or 12.6%).<\/p>\n\n\n\n

Social Security\u2019s two trust funds<\/a> (one for retirement benefits, one for disability insurance) together held nearly $2.7 trillion in special Treasury securities as of July 2025. Various military retirement funds held more than $2.2 trillion. And Medicare\u2019s two trust funds held a combined $425.3 billion.<\/p>\n\n\n\n

Because of data lags, we have to go back to December 2024 for a closer look at the private investors who hold the national debt. At that time, about $8.5 trillion (23.5% of the total) was held overseas, either by individuals or foreign governments. Mutual funds held nearly $4.5 trillion, or 12.4%. Banks and similar institutions held nearly $1.9 trillion, or 5.1%, while states and localities owned almost $1.7 trillion, or 4.6%. Public and private pension funds together held $955.7 billion in U.S. debt, or 2.6%. The rest was held by a mix of individuals, businesses, insurance companies, broker-dealers and others.<\/p>\n\n\n\n

\"A<\/a><\/figure>\n\n\n\n

Japan is the biggest foreign holder of U.S. debt.<\/strong> As of May 2025, Japan held more than $1.1 trillion, or 3.1%, of the country\u2019s total debt. Following Japan were the United Kingdom ($809.4 billion, or 2.2%) and China ($756.3 billion, or 2.1%).<\/p>\n\n\n\n

Interest on the national debt exceeds annual spending on Medicare, as well as national defense.<\/strong> In fiscal 2024, the government\u2019s net interest expense was $879.9 billion, or 13% of all that year\u2019s expenditures, according to data from the Office of Management and Budget. That was the highest share in a quarter-century. In dollars, it was slightly more than the government spent on Medicare ($874.1 billion) or national defense ($873.5 billion) in fiscal 2024. Interest on the debt is now the government\u2019s third-biggest major spending area, behind only Social Security and health care services and research.<\/p>\n\n\n\n

\"A<\/a><\/figure>\n\n\n\n

Net interest on the debt as a share of total federal outlays topped 15% in the mid-1990s. But for more than two decades thereafter, generally falling interest rates helped to constrain the government\u2019s annual interest costs, even as the total debt load continued to grow.<\/p>\n\n\n\n

That changed dramatically in the spring of 2022, when the Federal Reserve began raising its policy rate<\/a> \u2013 ultimately to its highest level in 15 years \u2013 to bring down soaring inflation. One side effect of that policy shift is that the U.S. has started paying more to borrow.<\/p>\n\n\n\n

The average interest rate on all federal debt, which had been as low as 1.556% in January 2022, has more than doubled to 3.352% as of July 2025. While still well below the levels of the 1980s and 1990s, that was the highest average rate since the 2007-09 Great Recession.<\/p>\n\n\n\n
