The formula

How this estimate works

For a quick planning estimate, the calculator multiplies your current gross monthly benefit by the COLA percentage, then adds that increase to your current benefit. It also multiplies the monthly results by 12 for annual figures.

Important limitation

Why SSA's exact number may differ

SSA applies COLA within its statutory benefit formula and uses specific truncation and rounding steps. Claiming-age adjustments, family benefits, withholding, and Medicare can also affect your final payment.
