How much did the U.S. national debt grow during Biden’s presidency compared to Trump’s tenure?
This fact-check may be outdated. Consider refreshing it to get the most current information.
Executive summary
Analyses disagree on exact totals, but major nonpartisan trackers show that debt held by the public rose roughly $6.0 trillion during Trump’s four-year term and about $6.9 trillion during Biden’s first three years and five months as measured by the Committee for a Responsible Federal Budget (CRFB) [1]. Other widely cited tallies put the dollar increase under Biden’s full four years between about $8.4 trillion and $8.5 trillion and Trump’s four years around $7.8–8.4 trillion, depending on methodology and inclusion of pandemic relief [2] [3] [4].
1. How different groups measure “debt added” — and why numbers vary
Observers diverge because they measure different things: “debt held by the public” excludes intragovernmental obligations and cash balances and is the economists’ preferred metric (CRFB), while headline figures often refer to gross national debt (which includes trust funds) or to authorized ten-year borrowing; sources also differ on whether to include one-off pandemic relief or executive actions [1] [5]. CRFB reported debt held by the public grew $6.0 trillion during Trump’s term and $6.9 trillion through Biden’s first three years and five months, while CRFB’s alternate counts of approved borrowing show Trump approved $8.4 trillion in new borrowing versus $4.3 trillion for Biden through mid-2024 when pandemic measures are counted differently [1].
2. The most-cited headline comparisons and their origins
Several widely cited tallies put Biden’s four-year debt increase at roughly $8.4–8.5 trillion and Trump’s at roughly $7.8–8.4 trillion. Investopedia reports Biden added about $8.4 trillion over four years and lists Trump’s first term at $7.8 trillion in its dataset [2]. Congressional and political statements—such as a 2025 Senate hearing and House Republican releases—have echoed similar $7.8–8.4 trillion ranges when assigning gross debt changes to each presidency [3] [6]. Those figures reflect gross debt-accounting and timing choices rather than a single neutral standard [2] [3].
3. Pandemic relief and executive actions are the largest complicating factors
Pandemic-era relief skews comparisons. CRFB shows excluding COVID relief changes the picture: Trump’s borrowing attributable to non‑pandemic policy falls from $8.4 trillion to $4.8 trillion; excluding the American Rescue Plan reduces Biden’s approved borrowing from $4.3 trillion to $2.2 trillion in their earlier analysis — illustrating how inclusion or exclusion of emergency legislation produces very different conclusions [1] [7]. News outlets such as Axios and The Hill relied on CRFB’s exclusions to note Trump’s non-pandemic additions were roughly double Biden’s [8] [7].
4. Politics shape how figures are presented — and disputed
Partisan actors contest methodology to advance narratives: House Republicans and the White House use different baselines to credit or blame each administration for debt trajectories — for example, the White House’s policy documents project improved debt-to-GDP under Trump’s proposed legislation while House Republicans have published “fact checks” disputing CRFB’s methods [9] [10]. The House Budget Committee explicitly accused CRFB of undercounting Biden’s contribution and overstating Trump’s relative performance, emphasizing rising interest costs as politically useful framing [10].
5. What independent fact-checkers and nonpartisan analysts say
PolitiFact and CRFB underscore that assigning debt to a president is inherently imprecise because long-standing laws and economic cycles drive much of the trajectory; PolitiFact noted Biden had accumulated about $6.32 trillion in his first three years and that CBO projected a $1.582 trillion deficit for his final year, which would push his four‑year total past Trump’s one-term figure in their analysis [4]. CRFB’s detailed work provides both a “debt held by the public” view and an “approved borrowing” tally, offering multiple lenses rather than a single definitive number [1] [5].
6. Bottom line for readers
Available sources do not agree on a single definitive number because definitions and timeframes matter; using CRFB’s preferred public-debt metric gives Trump +$6.0 trillion and Biden +$6.9 trillion through mid-2024 [1], while full-term gross-debt tallies reported elsewhere place Biden around $8.4–8.5 trillion and Trump near $7.8–8.4 trillion [2] [3]. Readers should treat any single headline as a product of methodological choices and look for whether pandemic relief, intragovernmental debt, and the chosen time window are included before drawing conclusions [1] [5].
Limitations: this summary relies only on the provided sources and therefore does not reflect any subsequent revisions or additional datasets beyond those documents [2] [1] [4].
