Social Security Projected To Run Out Of Funds In 20 Years, CBO Analysis

From Congressional Budget Office analysis, "As the Population Ages, Social Security’s Spending Is Projected to Outpace Its Tax Revenue" October 2, 2012:

CBO estimates that in fiscal year 2012, spending for Social Security totaled $773 billion, equal to about 5 percent of gross domestic product and one-fifth of federal spending. As more members of the baby-boom generation retire and the U.S. population grows older in the coming decades, Social Security outlays are projected to grow more rapidly than the economy and more rapidly than the program’s dedicated tax revenues.

Over the next 10 years, outlays will exceed dedicated tax revenues by about 10 percent, on average. That gap will grow larger in the 2020s, and by 2030, Social Security outlays will be about 6 percent of gross domestic product and will exceed dedicated tax revenues by about 20 percent. As a result, under current law, resources available to the Social Security program will become insufficient to pay full benefits in about 20 years, CBO projects.
