Detailed Single Year Tables

Category of Change: Level of Monthly Benefits (PIA)

Proposed Provision: For all individuals becoming eligible for OASDI benefits in 2009 and later, use a 

modified primary insurance amount (PIA) formula. The modified formula would increase the first bend 

point to $800 in 2009. Also, a new bend point would be placed between the reset first bend point and 

the current-law second bend point. The new bend point would be equal to the reset first bend point 

plus 75 percent of the difference between the bend points. The PIA formula factor between the new 

bend point and the upper bend point would be lowered from 32% to 20%. The PIA formula factor above 

the upper bend point would be lowered from 15% to 10%.
