National Debt

Overview

The national debt is the total amount of money the federal government has borrowed, plus interest. This borrowed money supplements taxpayer dollars to fund government operations, from national defense to welfare programs.

While taxes help pay for these programs, government spending often exceeds the revenue collected. The US government primarily sells bills, notes, and bonds (collectively called securities) to domestic and foreign individuals, companies, and other governments to cover the gap. This is called public debt. The government also has intragovernmental debt, or money one government sector owes to another. In both cases, the government promises to pay back the original value of the security plus interest to make it worth it for the lender.

The US has accrued debt since its infancy. Only seven years into nationhood, debts from the Revolutionary War totaled $43M. In recent years, the wars in Afghanistan and Iraq, the 2008 recession, and the COVID-19 pandemic have significantly increased the national debt. It surpassed US GDP in spring 2026, when the country's public debt was estimated to be $31.3T.
