How much is the interest on the United States’ National Debt?

National Debt Service

How much is our National Debt Service?  Stated another way, how much is the interest on the United States’ National Debt?

In the fiscal year ended September 30, 2009, the interest on the national debt was $383 billion, making Interest Expense one of the largest components of the federal budget.  In fact, interest on the national debt accounted for over 27% of our 2009 federal budget deficit. That’s a lot of “National Debt Service”, but it could have been much worse.
