A NIT set at 100% of the poverty line with a 50% phaseout rate would've cost $219 billion in 2004 (using 2007) dollars.

This program would eliminate poverty, and payments would phaseout entirely by 200% of the poverty line. Reducing the phaseout rate to 33% would have the payments phaseout by 303% of poverty, and raise the cost to $336 billion.
