How many years were averaged into AIME and how many of them are $0.

Field: AIME computation year counts Unit: count Basis: no dollar basis Computed by: UI-native Status: Complete chain

Calculation records

• Zero years in the averaged earnings Formula record, justified by derivation

  Purpose: Count how many of the years averaged into a worker's AIME have no earnings.

  Statement: socialSecurity/piaFromEarnings.ts#computePiaFromEarnings publishes zeroYearsInAime, the number of entries of yearsUsedInAime, the indexed amounts it averaged into the AIME, that are 0, beside computationYearCount, the number of those years. Units: years. Rounding: none; integers.

  Formula: zeroYearsInAime = count of v in yearsUsedInAime with v = 0

  • yearsUsedInAime: Indexed earnings of the benefit computation years, the largest after the dropout (unit: usd/year) (domain: nonnegative)

  Timing: once per earnings history

  Rounding: none

  Limits:

  • Counts the years this computation averaged, so it follows its computation-year window: always 35 years for a worker whose window has 40, the base years from 22 to 61 (usc-42-415-b-2-b-ii-iii-initial-computation-base-window)

Transformations

• socialSecurity/piaFromEarnings.ts#computePiaFromEarnings publishes computationYearCount and zeroYearsInAime, the number of averaged years whose indexed earnings are $0; the explainer prints both.
