The Congressional Budget Office estimates that the Budget Control Act of 2011 would reduce budget deficits by at least $2.1 trillion over the period of 2012 to 2021. It would do this by establishing caps on discretionary spending, allowing additional spending for initiatives to reduce improper payments, and establishing an automatic process to trigger spending reductions if other provisions do not achieve targeted savings. Compared to CBO's baseline estimates, the legislation would lower budget authority and outlays on discretionary spending by hundreds of billions of dollars over the next decade.
