Dollar-value assumptions
Social Security COLA: What It Changes
A Social Security cost-of-living adjustment (COLA) changes benefit amounts to reflect inflation. It is different from wage indexing used to calculate AIME and from delayed retirement credits earned by waiting beyond full retirement age.

Three adjustments that are easy to confuse
Wage indexing adjusts earlier earnings before AIME is calculated. The PIA formula converts AIME into the base benefit. Early reductions or delayed credits adjust for the claiming month. COLAs then change benefit amounts over time. Each step has a different purpose.
Constant dollars versus future dollars
Claiming Planner's constant formula-dollar mode excludes projected future COLAs, which makes claiming scenarios easier to compare on one basis. Future-dollar mode applies a visible 2.4% annual planning assumption. That assumption is not a prediction of future SSA announcements.
Do not compare a future nominal amount with a present-dollar budget without adjusting the rest of the plan consistently.
Refresh trigger
SSA determines COLAs from the statutory inflation measure and publishes new amounts. The site's rule set and explanatory pages should be reviewed when SSA releases annual updates. Personalized official benefit estimates remain the authoritative reference for filing.
