The current debt is about a trillion dollars, so you can multiply 0.01 by a trillion. That gives you the steady-state increase. In practice, of course, that debt is of varying maturity, so in the first year it will be the amount that rolls over in the first year. In the second year it will.... When the whole thing rolls over it will be 0.01 times a trillion. That could take several years.
