FERS COLAs: Why Your Pension Lags Inflation (and Pays Nothing Until 62)

Updated June 2026 · Educational only — not financial, tax, or legal advice

In 2026, CSRS retirees and Social Security recipients got a 2.8% cost-of-living raise. FERS retirees got 2.0%. Same inflation, smaller adjustment — and that's not a mistake. It's the FERS "diet COLA," and paired with a second rule that withholds COLAs entirely until age 62, it's the quiet reason a FERS pension slowly loses ground to inflation over a long retirement. Here's how it works, and why it matters more than most people realize.

Rule 1: The "diet" COLA

CSRS and Social Security get the full change in the CPI. FERS gets a reduced version whenever inflation runs above 2%:

That's why 2026's 2.8% CPI became a 2.0% FERS COLA. In a high-inflation year — say CPI at 5% — FERS retirees would get 4%, losing a full point. It sounds small in any single year. Over decades, it compounds.

Rule 2: No COLA until 62

Most FERS retirees receive no COLA at all until the year they turn 62 — even if they retired at 57. Retire early and your pension is frozen in nominal dollars during exactly the years you're relying on it most, then begins adjusting (at the diet rate) once you hit 62.

There are important exceptions. COLAs are paid regardless of age to:

• Special-provisions retirees — law enforcement officers, firefighters, and air traffic controllers;
• Disability retirees; and
• Survivor annuitants.

If you're in one of those groups, the age-62 freeze doesn't apply to you. Everyone else: plan around it.

What the gap does over time

The diet COLA looks trivial year to year. Stretched across a 30-year retirement, it opens a real gap between your pension and the cost of living it was meant to track.

What you can — and can't — do about it

You can't change the COLA rules, but you can plan for the erosion they cause:

• Lean on the leg you control: the TSP. Your pension's inflation protection is weak by design; your TSP and its growth are where you build the buffer. This is a core reason the three income legs work together — see building your retirement paycheck.
• Remember Social Security gets the full COLA. Delaying Social Security raises a benefit that does keep full pace with inflation — a meaningful hedge for the later decades. See when to claim.
• Don't expect the supplement to help. The FERS supplement gets no COLA at all and ends at 62 — it's a flat bridge, not an inflation-protected one.
• Factor the early-retirement freeze into your date. Retiring at 57 means up to five years of a frozen pension before COLAs even begin. It's one more input into choosing when to go.
