Social security PIA annualized

A claimant's monthly primary insurance amount (the full-retirement-age benefit, in the plan's first year) times twelve, as the couple primer prints it.

Field: PIA annualized Unit: US dollars Basis: today's dollars (real) Computed by: UI transformation Status: Complete chain

Appears in: ss-page (CoupleStrategyPanel couple primer "full-retirement-age benefit (PIA): $X/yr against $Y/yr")

Calculation records

• The PIA a Social Security stream is paid from Composition record, justified by derivation

  Purpose: Resolve a stream's monthly PIA once, for the projection, its insights and the Social Security pages.

  Statement: socialSecurity/piaFromEarnings.ts#resolveStreamPiaMonthly returns the entered PIA as entered; otherwise, for a stream with an earnings history, the PIA #computePiaFromEarnings gives on the history and its projection (#streamPiaFromEarningsInput, the projection defaulting to the person's retirement age), raised by #piaWithCostOfLivingIncreases from the eligibility year through the year before the projection starts, with the years whose increase SSA has not announced; otherwise no PIA, with the reason: no PIA and no earnings history, or the computation's error. projection/simulate.ts#simulatePlan, the claim-milestone insight and the planner's Social Security pages all call it. The couple primer prints the resolved PIA x 12. Units: dollars a month. Rounding: the PIA's own, to the dime.

  Limits:

  • An entered PIA is taken to be in the first year's dollars already, as a PIA shown on a current SSA statement is
  • The yearly figure the couple primer prints is PIA x 12, the benefit at full retirement age, not the benefit at the claim age
