The federal government spent $857 billion on net interest costs in the first nine months of fiscal year 2026, according to the Congressional Budget Office. That amounts to roughly $95.2 billion per month, or $737 monthly per U.S. household when divided among approximately 129 million households. The deficit reached $1.4 trillion over the same period, $35 billion higher than the prior year, pushing the national debt to $39.64 trillion as of July 2026. The interest expense now exceeds spending on the military or Medicare, and analysts warn that rising debt could lead to higher borrowing costs, inflation, and stagnant wages for ordinary Americans.
