Introduction

Depending on who you ask, President Barack Obama added anywhere from $2.8 trillion to $9 trillion to the national debt. With such a big gap, you might be wondering who’s lying. None of them, because there are three ways to look at the debt added by any president.

The first and most common method is to subtract the debt level when Obama took office from the debt level when he left. The second and more accurate method is to add together Obama’s projected budget deficits. The third method is the fairest but also the most complicated. It adds just the deficits created by the president’s specific initiatives.

Let’s take a look at each method and see what they tell us about the deficits President Obama added to the nation’s debt.

Methods

Method 1: Debt Added Since Obama Took Office

The largest number comes from calculating how much the debt increased during Obama’s two terms. When Obama was sworn in on Jan. 20, 2009, the debt was $10.626 trillion. When he left office on Jan. 20, 2017, it was $19.937 trillion. It explains why some would say Obama added $9 trillion to the debt.

Method 2: Obama’s Budget Deficits

The second method is to add up all of the budget deficits incurred while Obama was in office. You shouldn’t hold any president accountable for the deficit incurred during the first year. Most of that deficit belongs to the previous president since he created the federal budget for that year.

President George W. Bush’s last budget—for Fiscal Year (FY) 2009—created a deficit of $1.4 trillion.2 That fiscal year began on Oct. 1, 2008, and continued until Sept. 30, 2009. Although most of that deficit occurred after Obama took office, it was a result of Bush’s budget. Similarly, the first deficit that occurred after President Donald Trump took office was due to Obama’s last budget.

Here are Obama’s deficits by year. They total $6.807 trillion.

1. FY 2009:
   • Congress added $253.1 billion from Obama’s Economic Stimulus Act to Bush’s last budget after Obama took office.
   • This emergency funding was to stop the Great Recession. That $253 billion accrues to Obama, not Bush.
   • Once the $253 billion is subtracted from the FY 2009 deficit, it means Bush’s true budget deficit was $1.16 trillion.
2. FY 2010: Obama’s first budget created a deficit of just under $1.3 trillion.
3. FY 2011: This budget deficit was $1.3 trillion.
4. FY 2012: The deficit was $1.1 trillion.
5. FY 2013: This was the first Obama budget where the deficit, $680 billion, was less than $1 trillion.
6. FY 2014: The deficit was $483 billion.8 Tax revenue rose to $3.02 trillion.
7. FY 2015: The deficit fell further to $439 billion.
8. FY 2016: The deficit rose to $587 billion.
9. FY 2017: The deficit was $665 billion.
   • It was $162 billion more than the $503 billion deficit estimated in Obama’s budget request.

Like most presidents, Obama’s contribution to the debt was higher.

There’s a difference between the deficit and the debt.

Method 3: How Obama’s Policies Increased the Debt

The third method is to measure the debt incurred by Obama’s specific policies.

The Congressional Budget Office (CBO) has done that for many of them.

The American Recovery and Reinvestment Act (ARRA) contributed $830 billion between 2009 and 2019.

More than 90% of its budget impact occurred by the end of 2012.

It cut taxes, extended unemployment benefits, and funded job-creating public works projects.

Like the tax cuts, the ARRA stimulated the economy after the 2008 financial crisis.

Obama’s largest contribution to the debt was the Obama tax cuts, an extension of the Bush tax cuts.

They added $858 billion to the debt in 2011 and 2012.

Obama also increased military spending, with the highest level of spending occurring in 2011.

Here’s a breakdown:

1. Department of Defense base budget: $528.3 billion
2. Spending by defense-related agencies: $166.7 billion
3. Homeland Security: $41.9 billion
4. Veterans Affairs: $56.4 billion
5. State: $50.1 billion
6. FBI and Cybersecurity: $7.8 billion
7. National Nuclear Security Administration: $10.5 billion
8. Overseas Contingency Operations for DoD and defense-related agencies: $159.5 billion

 

Using this same methodology, Obama’s total defense spending was $6.3 trillion:

1. 2010: $857.7 billion
2. 2011: $854.5 billion
3. 2012: $816.3 billion
4. 2013: $746.1 billion
5. 2014: $753.3 billion
6. 2015: $735.4 billion
7. 2016: $767.2 billion
8. 2017: $773.5 billion

 

Summary

As a result, Obama’s policy of increased defense spending added $1.3 trillion to the debt over the baseline established by Bush.

The Patient Protection and Affordable Care Act added to the debt after 2014.

That’s when the health insurance exchanges opened, and coverage was extended to more low-income people.

Obamacare’s tax increases offset these costs by $143 billion between 2010 and 2019.

When all of this is added up, Obama and his policies increased the national debt by $2.8 trillion.

 

The Bottom Line

Depending on the method you use, Obama contributed between $2.8 trillion and $9 trillion to the overall U.S. national debt.

While that’s a large amount, it’s worth comparing to the national debt added by every other president.

That’s the best way to understand why the U.S. debt is so big.
