This table represents the unfunded liability by age of United States Citizens from ages 21 to 100 in 1999. The unfunded liability was calculated by using the OASI Formula and United States Census estimate for the middle population projection. The amount of money required to fully fund OASI to each age group was calculated. It is assumed everyone continues paying the current OASI tax rate.

In summary a person who turned 65 in 1999 would need to contribute an additional $148,662 to OASI before being able to draw their first check. On the other hand a 21 year old need pay nothing since their age is young enough to fully fund their OASI benefit working from age 23 to 65. The younger person has not paid into Social Security many years and as such has many more years remaining to pay in. On the other hand a person who is age 60 has only five more years left to pay into Social Security. Considering Social Security's large unfunded liability, it becomes obvious the sum total of all of this persons contributions went to previous retirees and not one cent was set aside for them. In other words they have not yet contributed to their OASI Benefit!
