At 3% annual inflation and no COLA, a $2,625/month pension loses 45% of its purchasing power in 20 years — the equivalent of living on $1,444 in today's dollars. Even a 2% COLA cap only partially offsets that erosion.
The 2026 FERS COLA is 2.5%. FERS COLA is calculated as CPI-W minus 1 percentage point when CPI-W is between 2–3%, the full CPI-W when under 2%, and capped at 2% when CPI-W exceeds 3%. CSRS receives the full CPI-W adjustment with no reduction.
