One inflation number sets next year's raise for about 75 million Americans: the CPI-W average for July, August, and September 2026. But that single number flows through five different statutory formulas, and depending on which retirement system you're in, the identical 3.6% produces 3.6%, 2.6%, or nothing.

Update, October 14, 2026: the number is in. September CPI-W came in at 330.654, putting the 2027 COLA at 3.6% for Social Security, CSRS, military High-3 and BRS retired pay, and (once Congress passes the annual act) VA compensation. FERS annuitants age 62 and over get 2.6%; REDUX and Career Status Bonus retirees get 2.6%. The two-month running count read 3.3%, but a flat September was never going to hold it. The tables below now show the settled figure for each system.

Five Systems, One Input

Every one of these formulas starts from the same place: the percentage change in the average CPI-W for the third quarter of 2026 versus the third quarter of 2025. What happens next depends on the statute:

System Formula Official 2027 COLA
Social Security Full CPI-W (42 U.S.C. 415(i)) 3.6%
CSRS Full CPI-W (5 U.S.C. 8340) 3.6%
FERS, age 62+ Diet COLA (5 U.S.C. 8462): full up to 2%, flat 2% in the 2-3% band, CPI-W minus 1 above 3% 2.6%
Military retired pay (High-3, BRS) Full CPI-W (10 U.S.C. 1401a) 3.6%
CSB/REDUX (before age 62) CPI-W minus 1 point when COLA exceeds 1% 2.6%
VA disability compensation Matched to the Social Security COLA by annual act of Congress 3.6% (once the act passes)
FERS, under 62 subject to the age bar No COLA until age 62; eligible special-provision, disability and survivor annuities follow separate rules 0% for retirees subject to the age bar

Two details in that table carry most of the arguments on Reddit. First, the military number is not special: High-3 and BRS retirees get exactly the Social Security percentage. Second, the FERS 2-to-3% band pays a flat 2%, not CPI-minus-1. That is why FERS paid 2.0% in both 2025 and 2026, and why the 3% line, crossed this year, switches the formula to CPI-W minus a point.

The Dollar Matrix

Here is what the official 3.6% pays across systems and benefit levels. This is the comparison nobody publishes side by side:

Annual benefit SS / CSRS / Military High-3 / VA (+3.6%) FERS 62+ / REDUX (+2.6%) FERS under 62 subject to the age bar
$24,000 +$864/yr (+$72/mo) +$624/yr (+$52/mo) $0
$35,000 +$1,260/yr (+$105/mo) +$910/yr (+$76/mo) $0
$45,000 +$1,620/yr (+$135/mo) +$1,170/yr (+$98/mo) $0
$60,000 +$2,160/yr (+$180/mo) +$1,560/yr (+$130/mo) $0

FedTools computation at the official 2027 COLA (annual = benefit × rate; monthly = annual ÷ 12, rounded to the dollar). Gross annual increases; the VA column applies once the annual act passes. The last column covers FERS retirees subject to the age-62 bar in 5 U.S.C. § 8462(c)(3); retirees under the special provisions (law enforcement, firefighter, air traffic controller and similar), disability annuitants and survivor annuitants receive COLAs under their own rules.

A household with a CSRS annuity and a spouse on a FERS annuity will see two different percentages on the same news story. A military retiree drawing both retired pay and VA disability gets the full rate on both. A 58-year-old VERA taker gets zero on the annuity but the full rate on any Social Security they claim later, because the under-62 freeze applies only to the FERS annuity itself.

How the Last Three Years Compare

System 2025 2026 2027 (official)
Social Security / CSRS / Military High-3 / VA (VA pending the annual act) 2.5% 2.8% 3.6%
FERS 62+ 2.0% 2.0% 2.6%
CSB/REDUX 1.5% 1.8% 2.6%

Notice the FERS row: 2.0%, 2.0%, and now 2.6%, even as the full-COLA systems climbed. The flat-2% band caught FERS retirees in both 2025 and 2026. With the COLA above 3%, the formula has flipped to minus-1, which at 3.6% means 2.6% for FERS against 3.6% for CSRS, a 1-point gap on every dollar. Our FERS diet-COLA cumulative-loss analysis totals what that gap has cost since 2000.

REDUX retirees carry the same minus-1 in a different wrapper: it applies in any year the COLA tops 1%, with a one-time catch-up at 62 before the penalty resumes.

The Timing Fine Print

The percentages get announced together in mid-October, but the checks move on slightly different schedules:

  • Social Security: higher payment arrives January 2027.
  • CSRS/FERS: COLA effective December 1, 2026, first visible in the January 2027 annuity payment. First-year retirees get a prorated share based on months on the annuity roll.
  • Military retired pay: same December effective date, January payment.
  • VA disability: January 2027 payment, once the annual COLA act passes. It has virtually always passed.

No data release remains: BLS published the September CPI-W (330.654) on October 14, and the three-month average settled the number. August's release on September 11 had moved the count from 3.1% to 3.3%; September carried it to 3.6%. We keep the live 2027 COLA tracker as the month-by-month record.

Frequently Asked Questions

What is the 2027 COLA?

3.6% for Social Security, CSRS, military High-3 and BRS retired pay, and VA disability once the annual act passes. FERS retirees 62 and over and REDUX retirees get 2.6%. BLS published September CPI-W at 330.654 on October 14, 2026.

Is there a separate military COLA?

No. Military High-3 and BRS retired pay use the same CPI-W formula as Social Security.

Why is the FERS number lower?

The statutory diet-COLA: flat 2% in the 2-3% band, CPI-W minus 1 above 3%. And most FERS retirees under 62 get nothing at all. At the official 3.6%, FERS 62+ gets 2.6%.

Does VA disability automatically match Social Security?

By annual act of Congress rather than permanent formula, but it has virtually always passed, so in practice the rates match.

When will I see the money?

January 2027 payments for Social Security, CSRS, FERS and military retired pay, following the October 14 announcement; the increase is effective December 1, 2026. VA's projected 3.6% increase depends on enactment of the annual Veterans' Compensation COLA Act.
