This calculator allows users to place specific tax or spending numbers
in the context of the total U.S. budget. It converts dollar amounts
into either dollars per capita, that is per U.S. citizen, or into a percentage
of total revenues, total discretionary spending, or the total budget
(including nondiscretionary spending). It also provides a visual
comparison showing the size of the specific spending or revenue item
relative to projected defense spending over the time period in question.
