National Debt by Year Compared to GDP and Major Events

U.S. Debt by Year Since 1929

Updated September 18, 2018

The U.S. national debt is more than $21 trillion. It exceeded that amount on March 15, 2018. It's greater than the economic output of the entire country. It occurred despite Congressional attempts to cut government spending. These included threats to not raise the debt ceiling and the U.S. debt crisis in 2011. That's when the U.S. headed toward a debt default. It continued with the fiscal cliff crisis in 2012 and a government shutdown in 2013.

Sequestration slowed, but didn't halt, deficit spending beginning in 2013.

You can't look at a country's national debt in isolation. Sometimes expansionary fiscal policy, such as spending and tax cuts, was needed to spur the economy out of recession. Other times, the United States increased military spending to respond to national threats.

For those reasons, the national debt by year should be compared to the size of the economy as measured by the gross domestic product. This gives you the debt to GDP ratio. You can use it to compare the national debt to other countries. It also gives you an idea of how likely the country is to pay its debt back.

The government creates debt with either excessive spending or deep tax cuts. If this expansionary fiscal policy boosts growth, it can begin to lower the debt. That's because a growing economy will produce more tax revenues to pay back the debt. The theory of supply-side economics says the growth will be enough to replace the tax revenue lost.

But that only occurs if taxes are too high, say above 50 percent of income.

There are other events that can increase the national debt. For example, the U.S. debt grew after the 9/11 attacks as the country increased military spending to launch the War on Terror. Between FY 2001-FY 2017, it cost $1.9 trillion.

This included increases to the Department of Defense and the Veterans Administration.

In the table below, the U.S. debt by year is compared to GDP and national events since 1929. Please note that the debt and GDP are given as of the end of the third quarter (September 30) in each year to coincide with the fiscal year. That's the best way to accurately determine how spending in each fiscal year contributes to the debt and to compare it to economic growth. Please note: GDP in the years up to 1947 are not available for the third quarter, so year-end figures are used.
