Reducing America’s mounting federal debt could eventually leave the average household with almost $36,000 more annual income than under a rapidly rising debt scenario, according to new analysis examining the economic consequences of persistent government borrowing.
The Committee for a Responsible Federal Budget, or CRFB, argues that stabilising the US national debt relative to the economy could improve household finances through several channels, including lower interest rates, slower price growth and stronger private investment. Its analysis comes after gross federal debt passed $40 trillion and as borrowing costs remain a growing part of Washington’s budget pressures.
A $36,000 Difference for American Households
The CRFB bases its long-term income estimates on modelling from the Congressional Budget Office. It says real income per person could rise by $46,500 over the next three decades under a stable-debt scenario, compared with $32,350 if debt increases rapidly.
That difference translates into $14,250 more annual income per person by the end of the period, or almost $36,000 per household, according to the committee. The figure describes the estimated difference between economic scenarios rather than an immediate payment or guaranteed increase in household earnings.
Borrowing costs provide a more immediate illustration of the argument. CRFB estimates that a 1.5 percentage point reduction in interest rates would cut the annual cost of a new $500,000 mortgage by about $5,800. The same rate reduction would save roughly $500 annually on a new $50,000 car loan.
The committee argues that smaller federal deficits could reduce pressure on interest rates by limiting Treasury borrowing and helping moderate inflation. It also says lower government borrowing could leave more capital available for private-sector investment.
The argument matters while inflation remains above the Federal Reserve’s 2% target. CRFB estimates prices have increased 24% since March 2021, compared with an 11% increase had inflation remained at the Fed’s target throughout the period.
Why Federal Borrowing Can Reach Private Balance Sheets
The link between government debt and household prosperity is largely about capital allocation. When Washington borrows heavily, government financing competes with companies and households for available capital. CRFB cites CBO estimates suggesting every dollar of additional federal borrowing reduces private investment by roughly 33 cents.
Less private investment can eventually mean a smaller stock of equipment, buildings, software and research available to workers. That can weigh on productivity and, over time, incomes.
The scale of federal borrowing gives the issue greater significance. CBO’s February 2026 baseline projected a $1.9 trillion federal deficit for fiscal 2026 and forecast debt held by the public rising from 101% of GDP this year to 120% by 2036. CBO attributed the longer-term increase partly to Social Security, Medicare and rising net interest costs.
That distinction is important because gross federal debt and debt held by the public measure different things. The $40 trillion headline figure includes intragovernmental holdings, while debt held by the public is generally the measure economists use when examining federal borrowing relative to the wider economy.
There is also no single agreed threshold at which government debt automatically becomes unsustainable. The economic consequences depend on interest rates, growth, inflation, investor demand and the policies used to address deficits. Reducing deficits through spending changes can produce different effects from doing so through higher taxes, particularly across different income groups.
The Trade-Off Behind Lower Deficits
The potential household gains therefore depend heavily on how Washington approaches fiscal consolidation. CRFB argues that deficit reduction can support lower inflation and borrowing costs, but fiscal policy cannot independently resolve housing shortages, energy costs, healthcare expenses or other pressures on household budgets.
CBO research also illustrates why timing matters. Its analysis of debt stabilisation found that delaying action requires larger subsequent policy changes and can result in higher interest costs and weaker household consumption over the long term.
For investors and businesses, the key indicators will be the trajectory of federal deficits, Treasury yields and interest expenditure rather than the $40 trillion headline alone. Those measures will help determine whether government borrowing increasingly absorbs capital that might otherwise finance homes, corporate investment and productivity growth.
The central question for Congress is therefore not simply whether debt should fall, but what combination of spending, taxation and economic growth could stabilise it without creating offsetting costs elsewhere in the economy.
