Federal debt outstanding crossed $40 trillion on or around Aug. 19, 2026. That doubling has revived ranking presidents by debt added. Using Treasury’s “Debt to the Penny” series from start to end of term in nominal dollars, Joe Biden’s single term added roughly $8.45 trillion, placing him third among the last five presidents. Donald Trump ranks first; Barack Obama second.
Five-President Debt Ranking
Measured by actual increase in total public debt outstanding: Trump, both terms combined, roughly $11.63 trillion, of which roughly $7.80 trillion came in term one and roughly $3.83 trillion in the first 19 months of term two; Obama, two terms, roughly $9.32 trillion; Biden, one term, roughly $8.45 trillion; George W. Bush, two terms, roughly $4.90 trillion; and Reagan, two terms, roughly $1.86 trillion.
Trump ranks first because his two non-consecutive terms are combined. Measured term by term, Biden’s roughly $8.45 trillion exceeds Trump’s first term of roughly $7.80 trillion. His second term is still in progress, so his total will keep growing and is not a finished, comparable number like the others. Combining terms is a legitimate approach and the one Newsweek used in its Aug. 20, 2026 analysis, which independently produced essentially the same totals.
What “Added to the Debt” Means
The “$8 trillion” is rounded shorthand for the roughly $8.45 trillion Treasury figure. A debt increase reflects the gap between spending and revenue plus other financing needs, not spending alone. Tax cuts, revenue shortfalls, and interest costs each contribute independently. “Spending president” is common shorthand; the label is imprecise.
A separate measurement matters. The nonpartisan Committee for a Responsible Federal Budget, in an April 3, 2025 analysis, estimated that Biden-era legislation and executive actions added a projected $4.7 trillion in new debt over a 10-year window, scored at enactment. That figure differs from Treasury’s $8.45 trillion. CRFB counts only new policy choices as scored at enactment; it excludes pre-existing mandatory spending growth, revenue performance, and rising interest costs on existing debt. The two figures are not in conflict.
CRFB’s breakdown includes $2.06 trillion for the American Rescue Plan and COVID relief, $1.61 trillion in FY2022-2024 appropriations, $440 billion for the Bipartisan Infrastructure Law, and $620 billion in student loan initiatives, partially offset by the Fiscal Responsibility Act debt-limit deal at negative $1.53 trillion and the Inflation Reduction Act at negative $250 billion.
Trump’s Second Term
The Congressional Budget Office’s final conventional score for the One Big Beautiful Bill Act was roughly $3.4 trillion over 10 years, reported in July 2025. CRFB later published a dynamic score of roughly $4.7 trillion on March 11, 2026, incorporating economic feedback and debt-service costs. On the revenue side, tariff refunds following court rulings produced negative net customs receipts for three consecutive months in 2026, and July 2026 alone posted a $432 billion monthly deficit, the fourth-highest in U.S. history.
Structural Reality
Mandatory spending, Social Security, Medicare, Medicaid and veterans’ benefits, consumes about 60% of the roughly $7 trillion annual federal budget. Interest payments now exceed Pentagon funding and rank second only to Social Security. With the 10-year Treasury yield at 4.7% and the 30-year at 5.23% as of Aug. 24, 2026, refinancing gets more expensive with every maturing bill.
Treasury Secretary Scott Bessent, on the milestone: “There’s nothing magic about the $40 trillion number. We can grow our way out of that.” Margaret Spellings of the Bipartisan Policy Center disagrees: “Federal debt is already raising the cost of living and choking out other spending and investment.”
Debt growth under any president is not solely his doing. Congress writes and passes legislation. Entitlement spending grows on autopilot. Interest costs track the debt’s accumulated size and prevailing rates. Reagan-era figures rest on secondary compilations, since Treasury’s daily dataset only begins in April 1993. All five of the last five presidencies added trillions in nominal terms. Nominal dollars added, percentage increase, and legislation enacted each produce different answers. This ranking is one defensible measure, not the final word.
