April inflation hit 3.9%. The 2027 COLA just locked in a new trajectory.
April 2026 CPI-W came in at +3.9% year-over-year — the highest reading since 2023 — and pushed the 2027 COLA running count to 2.92%. The number is one tenth of a point away from crossing the 3.0% threshold that flips FERS retirees out of the 2% flat cap. With five months until the official announcement, the math has shifted: this is no longer a 2% year for FERS.
1. What the April CPI actually said
The Bureau of Labor Statistics released April 2026 CPI data on May 13. The numbers that matter for federal retirees:
- CPI-W rose 3.9% year-over-year in April 2026 — the index Social Security and federal retirement use for COLA calculations
- Broad CPI rose 3.8% year-over-year, the highest reading since May 2023
- April CPI-W came in at 326.541, up 0.94% from March alone
- The driver was energy: gasoline and fuel prices led the increase, with shelter, food, and transportation also rising
The April reading doesn’t directly enter the 2027 COLA calculation — only the third quarter does — but it changes the trajectory. Two months ago, the running count was around 1.1% and forecasters were calling for a 2026-style sub-3% COLA. The March reading bumped it up. The April reading bumped it again, and harder.
The current running count: April 2026 CPI-W of 326.541 is 2.92% above the Q3 2025 baseline of 317.265. We’re less than one tenth of a percentage point away from crossing the 3.0% threshold, with five more monthly readings to come before the September data closes the calculation.
The FERS COLA formula has a hinge point at exactly 3.0%. Below that, FERS retirees get a flat 2% (or the full CPI-W if it’s under 2%). Above 3.0%, the formula switches to CPI-W minus 1 percentage point. A CPI-W of 3.0% and a CPI-W of 3.1% both produce a FERS COLA of 2.0% to 2.1% — barely different at the boundary. But every tenth of a point above 3.0% adds to the FERS COLA directly. At 3.9%, FERS retirees would receive 2.9% — nearly a full point more than the 2.0% they got for 2026.
2. The FERS cap mechanics, with current numbers
The full FERS COLA rule applied to a range of possible 2027 outcomes:
| If CPI-W ends at | CSRS / Social Security gets | FERS gets | Gap | FERS rule applied |
|---|---|---|---|---|
| 2.0% | 2.0% | 2.0% | 0.0 pts | Full (CPI-W ≤ 2%) |
| 2.5% | 2.5% | 2.0% | 0.5 pts | Capped at 2% (between 2–3%) |
| 2.8% | 2.8% | 2.0% | 0.8 pts | Capped at 2% |
| 3.0% | 3.0% | 2.0% | 1.0 pts | Boundary — still capped at 2% |
| 3.5% | 3.5% | 2.5% | 1.0 pts | CPI-W minus 1 |
| 3.9% (TSCL projection) | 3.9% | 2.9% | 1.0 pts | CPI-W minus 1 |
| 4.2% (Mary Johnson) | 4.2% | 3.2% | 1.0 pts | CPI-W minus 1 |
The pattern: FERS retirees lose nothing relative to CSRS when inflation is low. The gap widens as CPI-W moves from 2.0% to 3.0%, peaks at exactly 3.0% (1.0 point gap), and stays at 1.0 point above that. Above 3.0%, FERS COLA mathematically rises in lockstep with CSRS — one point lower, but moving the same direction.
For the 2027 COLA at the current trajectory, FERS retirees are looking at something in the 2.5% to 3.2% range, depending on how the remaining monthly CPI-W readings come in. That’s meaningfully higher than the 2.0% they received for 2026.
3. What it means for your annual annuity
The percentage moves real money. For typical FERS annuity amounts, here’s what each scenario adds:
| Current gross annuity | At 2.0% FERS COLA | At 2.5% FERS | At 2.9% FERS (CPI-W 3.9%) | At 3.2% FERS (CPI-W 4.2%) |
|---|---|---|---|---|
| $20,000 | +$400 / $33 mo | +$500 / $42 mo | +$580 / $48 mo | +$640 / $53 mo |
| $30,000 | +$600 / $50 mo | +$750 / $63 mo | +$870 / $73 mo | +$960 / $80 mo |
| $40,000 | +$800 / $67 mo | +$1,000 / $83 mo | +$1,160 / $97 mo | +$1,280 / $107 mo |
| $50,000 | +$1,000 / $83 mo | +$1,250 / $104 mo | +$1,450 / $121 mo | +$1,600 / $133 mo |
| $60,000 | +$1,200 / $100 mo | +$1,500 / $125 mo | +$1,740 / $145 mo | +$1,920 / $160 mo |
For a federal retiree with a $40,000 annuity, the difference between the 2.0% scenario (where many were budgeting) and the current 2.9% trajectory is about $30 a month, or $360 a year. Over a 25-year retirement, that compounding difference is roughly $9,000 of additional income — not adjusted for the fact that subsequent COLAs compound on the higher base.
The compounding piece deserves attention. COLA is applied to the previous year’s annuity, so a 2.9% bump in 2027 makes every future COLA work off a larger base. A retiree who locks in an extra point of COLA this year carries that delta forward forever.
The difference between the 2% year FERS retirees were braced for and the 2.9% trajectory currently in view isn’t cosmetic. For a $40,000 annuity, it’s the equivalent of working an extra month of pre-retirement service for free — every year going forward.
4. What to do with this right now
Three practical responses for federal retirees and near-retirees:
If you’re building a 2027 budget, plan for 2.5% to 3.0% FERS, not 2.0%. The current trajectory could pull back if May, June, and July CPI-W show inflation cooling, but starting from the 2.0% assumption is no longer the central case. Better to plan for a moderate increase and treat anything higher as upside than to budget tight and adjust upward.
If your 2027 income planning includes Social Security, remember it gets the uncapped number. A FERS retiree who also draws Social Security sees both adjustments — FERS at the capped/reduced rate, Social Security at the full CPI-W. The Social Security side is doing more of the inflation-protection work in years like this.
If you’re a near-retiree planning retirement around the 2027 calendar, the timing isn’t materially affected. Federal annuities receive their first COLA in the January following retirement only if the retiree retired before December 1 of the prior year. A retirement in 2026 captures the 2027 COLA; a retirement in early 2027 generally doesn’t until 2028.
If you’re a CSRS retiree, you receive the full CPI-W — whatever it ends up being. The cap doesn’t apply to CSRS. Same for Social Security beneficiaries. The full inflation pass-through is one of the structural advantages CSRS retirees have always had over FERS.

The April 2026 CPI-W data referenced in this dispatch was released by the Bureau of Labor Statistics on May 13, 2026. The May 2026 CPI release is scheduled for June 11, 2026, and will refine the trajectory further. The official 2027 COLA is set by the Q3 2026 CPI-W average (July through September), announced by the Social Security Administration on October 14, 2026. Numbers in this dispatch are accurate as of publication; the running count and projections will continue to move with each monthly release.
Frequently asked questions
When is the 2027 COLA officially announced?
The Social Security Administration officially announces the 2027 COLA on October 14, 2026, after the Bureau of Labor Statistics releases the September 2026 CPI data. The COLA is calculated by averaging CPI-W for July, August, and September 2026 and comparing that average to the same three months in 2025. The percentage increase, rounded to the nearest tenth, becomes the COLA. Only third-quarter data drives the final number — April, May, and June readings shape projections but don’t enter the calculation.
Why is the FERS COLA always smaller than the CSRS COLA?
By statute, FERS COLAs are reduced when inflation exceeds 2.0%. If CPI-W rises 2.0% or less, FERS retirees receive the full CPI-W increase. If CPI-W rises between 2.0% and 3.0%, FERS retirees receive a flat 2.0% — capped. If CPI-W rises above 3.0%, FERS retirees receive CPI-W minus 1.0 percentage point. CSRS retirees and Social Security beneficiaries always receive the full CPI-W increase, never capped. The gap between FERS and CSRS is always 0 to 1 percentage point depending on the inflation level.
Do FERS retirees under 62 get the 2027 COLA?
Most do not. FERS retirees under age 62 generally do not receive any COLA until they reach 62. The exceptions are special-category retirees (law enforcement officers, firefighters, air traffic controllers), disability retirees, and survivor annuitants — all of whom receive COLAs regardless of age. Standard FERS retirees who retire under MRA+30, age 60+20, or MRA+10 typically see their first COLA in the January following their 62nd birthday.
Can the 2027 COLA change between now and October?
Yes. The official COLA is fixed only by third-quarter CPI-W data, so May and June CPI-W can pull the number up or down before July, August, and September even land. The current running count is informative but not binding. A sudden drop in inflation through summer could pull the COLA back to the 2.5% to 3.0% range. A continued surge could push it above 4%. The projections from TSCL, Mary Johnson, and the Federal Reserve all reflect different inflation assumptions for the remaining months.
