US Debt Hits $40 Trillion: What It Means For Your Money

The U.S. just crossed a milestone that would have been almost impossible to imagine a generation ago: $40 trillion in national debt.

For most households, that number is almost impossible to comprehend. Putting it into perspective, the debt comes out to $116,486 per U.S. citizen. And the impact of that debt can extend well beyond the headline figure, as it influences borrowing costs, inflation, taxes, and retirement programs.

Treasury Secretary Scott Bessent has argued that the U.S. can "grow its way out" of the debt, pointing to investments in factories and equipment that could expand the economy and ultimately the tax base.

There is some economic logic behind that argument. A growing economy can make a large debt burden more manageable if GDP expands faster than debt and interest costs. The problem is that current projections don’t show the U.S. moving in that direction.

The Congressional Budget Office projects federal debt held by the public will rise from 101% of GDP in 2026 to 120% by 2036. At the same time, annual interest costs are projected to more than double, from $1 trillion this year to $2.1 trillion in 2036.

That matters to households because government borrowing doesn’t exist in a vacuum. Higher Treasury yields can feed into the rates consumers pay on mortgages, auto loans and other forms of credit. One recent analysis from the Yale Budget Lab estimated that the increase in federal debt from 2015 through 2025 added roughly $2,500 to the annual cost of a median mortgage and $120 to the average auto loan.

For advisors, this is where the $40 trillion headline becomes relevant to everyday planning.

Younger clients may feel it through housing affordability and borrowing costs. Older clients may feel it through the potential impact on inflation, bond yields, taxes and government programs. And across generations, higher rates can change the assumptions behind everything from a home purchase to a retirement-income plan.

The takeaway isn’t to predict a debt crisis. It’s to recognize that fiscal policy is increasingly becoming a household financial issue. Advisors may want to stress-test plans for a world where rates, inflation and government finances don’t behave as favorably as they have in the past.

The $40 trillion milestone may be easy to dismiss as a headline. The ripple effects are harder to ignore.
