Social Security accuracy and testing

This page documents how Calwarden builds trust for this calculator: source notes, regression-style default tests, limitations, assumptions, unit handling, rounding, and visible change history.

Formula source

  • The calculator uses standard SSA reduction and credit formulas: • **Early (62)**: Benefit is reduced by ~25-30% compared to FRA. • **Full Retirement Age (66-67)**: You receive 100% of your Primary Insurance Amount (PIA). • **Late (70)**: You earn Delayed Retirement Credits, increasing your benefit by 8% per year up to age 70.

Test cases

Default input regression check

Generated from the checked-in default inputs and calculate function.

Inputs

  • Annual SSA Rule Preset: ssa_2026
  • Est. Benefit at Full Age (PIA): $2,000
  • Manual Max FRA Benefit: $4,152
  • Year of Birth: 1,960

Expected outputs

  • Age 62 (Early): $1,400.00
  • Full Retirement Age: $2,000.00
  • Age 70 (Late): $2,480.00

Known limitations

  • This is an estimator. It assumes a standard FRA of 67 (born 1960+) and simplified reduction factors. Actual SSA calculations involve complex indexing of lifetime earnings.

Assumptions

  • Inputs are interpreted exactly as entered in the calculator form.
  • The calculation runs locally in the browser using the current checked-in calculator definition.

Unit handling
