Live side-by-side comparison of government debt. United States currently owes about 440.3× more — a gap of $39.81 trillion. Updated every second from IMF baselines.
By total government debt, Iran ranks 56th-largest and United States ranks 1st-largest among the 137 sovereigns tracked on this site.
On a per-citizen basis the picture can look different from the nominal totals: a resident's notional share of the national debt in United States is roughly 114.0× that in Iran ($118,739 vs $1,042 per person).
The debt-to-GDP picture is asymmetric here: United States sits at 124% of GDP, well above Iran's 40%, meaning United States owes far more relative to the size of its own economy — even where the nominal, dollar-for-dollar comparison above suggests otherwise.
The gap between them is widening: United States's debt is growing faster in dollar terms ($60K/sec vs $254/sec for Iran), adding roughly $5,179,334,400 to the difference each day.
Scale is part of the story too: United States's population (336M) is about 3.9× Iran's (87M), which is part of why the nominal and per-capita comparisons above can point in different directions — a government's debt load scales loosely with the size of both its economy and its population, not either alone.
