Notable Observations

  • Highest FERS COLA: 7.7% in 2022 and 2023 (during high inflation period)
  • Lowest FERS COLA: 0.0% in 2010, 2015, and 2016 (during deflation or zero inflation)
  • Most years at 2% cap: 1990s saw 8 out of 10 years capped at 2%
  • Recent trend: 2020s have seen higher volatility with both 0% and 7.7% years
  • Long-term average: FERS COLA has averaged approximately 2.1% since 1987

Important Context: The 2% cap applied in most years between 1987-2021 because inflation remained in the 2-8% range. Only during extreme inflation (2022-2023) did FERS COLA exceed 2% significantly.

Cumulative Impact Analysis

Understanding the cumulative effect of reduced FERS COLA over a typical retirement helps illustrate why this matters for long-term financial planning.

20-Year Retirement Scenario

Assume a retiree begins with a $30,000 annual pension in 1990. Here's how FERS vs CSRS pensions would compare after 20 years:

Metric FERS Pension CSRS Pension Difference
Starting Pension (1990) $30,000 $30,000 $0
Pension After 20 Years (2010) $43,200 $51,600 -$8,400/year
Total Received Over 20 Years $712,000 $798,000 -$86,000
Purchasing Power (2010 dollars) $32,400 $38,700 -16%

Analysis: Over a 20-year retirement, the reduced FERS COLA results in approximately $86,000 less total income and 16% lower purchasing power compared to CSRS.
