Donald Trump entered the White House with bold promises — cut wasteful spending, slash deficits, and reduce national debt. Yet, he is on track to add more than $12 trillion to the national debt, setting a record for any US president in history.

Debt Levels Reach Historic Heights

The US national debt has now hit $37 trillion. Experts project it will cross $50 trillion within the next decade. Strikingly, more than a third of this new debt will directly stem from Trump’s policies.

This outcome is the exact opposite of what Trump pledged during the start of his second term. His administration launched the Department of Government Efficiency (Doge), cut over 100,000 government jobs, shut departments, ended many programs, and drastically reduced foreign aid. These moves aimed to lower borrowing. However, the overall effect went in the other direction — debt kept rising.

The Cost of the ‘One Big Beautiful Bill’

According to the Congressional Budget Office (CBO), Trump’s signature economic policy — the One Big Beautiful Bill (OBBB) — will add about $5 trillion to the national debt over the next ten years.

The breakdown includes:

• $4.1 trillion from OBB itself — $3.4 trillion in primary debt and $700 billion in extra costs.

• An additional $900 billion if temporary OBB provisions become permanent.

The Bigger Picture by 2034

By 2034, this Trump-driven $5 trillion debt will combine with the already expected $12.6 trillion increase in national debt. Together, this will push the total debt to $54.6 trillion, CBO estimates.

Trump’s first term (2017–21) had already added $7.8 trillion to the debt. Adding this to his second-term figures, his presidency will contribute around $12.8 trillion in total — the highest debt increase by any American president.

Trump’s Share of the Debt

By 2034, Trump’s policies will account for $12.8 trillion of the projected $54.6 trillion debt — about 23.44 percent of the total.
