Ask Explore Build Tailor Social Security States Generations Bill tracker Build Build a package Each policy carries a ten-year score, most of them published by CBO, JCT, Treasury or a research group; the source is named under each. Ticking one that conflicts with another swaps them. A positive figure adds to the deficit; a negative one reduces it.
Start from your values Pick a starting philosophy and the calculator chooses a package for it. The choice is mechanical: each policy carries tags for who pays, the size of government, the growth cost and the generations it falls on, and the same values always give the same package. It is a starting point, not a verdict; everything stays editable in the list below.
