The claim's $600 billion-per-point figure is roughly double or more the cost estimates in the sources, which run from about $95 billion to roughly $300–400 billion a year per percentage point, depending on the model. The direction is right, since higher rates do raise federal interest costs, but the magnitude is grossly off.

This claim is about the present, so it is judged as of the day it was checked.

What was said

… Let's, let's play that little clip that we have. We could have a GDP of ten, twelve, 15 times if they just leave us alone. Let us, let the rates go down. We should pay the lowest interest rates. You know, every point of interest is 600 billion dollars. Think of that. Every point of interest is 600 billion. Two points means we make a fortune, but we keep driving it up. It's a very unfair system, and I've said it now for a long time. When our country does well, interest rates should go down. …

What we found

Contradicts. Bank of America's estimate, reported by Fortune, puts a 1 percentage point rate increase at about $95 billion a year in national debt interest, far below the claimed $600 billion.[2]

Contradicts. CBO figures in the same Fortune report imply about $330 billion a year per point: a 1.5-point scenario adds $4.9 trillion in net interest over 2026–2036, and a 0.5-point scenario adds $1.9 trillion.[2]

Contradicts. Earlier CBO and Washington Examiner estimates put the cost per percentage point at about $180–200 billion a year, also well below $600 billion.[3][4]

Context. Brookings reports the federal government spent about $970 billion on interest in fiscal year 2025, with an average rate of 3.3% on the debt. A full 1-point repricing of that debt would cost roughly $300 billion a year, which is about half the claimed figure.[1]

Context. The National Review quote of Trump using the figure of $650 billion is the claimant's own statement and cannot corroborate the claim. Source 11 says Trump made the $600 billion argument on August 19, 2026, and treats it as a rhetorical claim that mixes several ideas.[5][6]
