2027 COLA for Federal Retirees: Monthly Tracker and What FERS Retirees Need to Know
Last Updated: April 12, 2026
The 2027 COLA for federal retirees will be announced in October 2026. But the CPI-W data that determines it is released monthly, so we can track where it's heading right now.
Through March 2026 data: approximately 2.0% running count. That's a significant jump from January's 0.2%, driven by a March inflation spike tied to rising energy prices. Analyst projections for the final 2027 COLA have shifted upward to the 2.8%-3.3% range. For context, the 2026 COLA was 2.8% for CSRS retirees but only 2.0% for FERS retirees, thanks to the FERS cap.
This page tracks the 2027 COLA month by month and explains exactly how the FERS COLA cap works, because it costs FERS retirees money every single year that inflation runs above 2%.
April 2026 update: inflation spike shifts the outlook
April 12, 2026
March 2026 changed the picture. The CPI-W came in at 323.500, a 3.3% year-over-year increase and a notable monthly surge. That single reading pushed the Q1 running count from 0.7% at the end of February to roughly 2.0% against the Q3 2025 baseline.
FedSmith published an analysis on April 10 explaining what drove it: an energy shock following the outbreak of the Iran war in late February sent oil and gasoline prices higher, and those costs cascaded into transportation and consumer goods prices. The March CPI reading was the first full month to capture that effect. Forecasters are split on whether it will stick through summer. The Senior Citizens League now projects 2.8% for the full year, CBO projects 3.1%, and some OECD scenarios run as high as 4.2% if oil prices remain elevated into Q3.
What this means for the 2027 COLA projection:
Before the March data, projections were clustered around 2.6%-2.8%. After it, estimates moved to 2.8%-3.3%, with the range depending on how energy prices behave through the summer months that actually determine the final COLA (July, August, and September 2026).
FedSmith laid out three scenarios:
| Scenario | Energy Price Path | Projected 2027 COLA |
|---|---|---|
| Conflict eases | Oil prices retreat | 2.5%-3.0% |
| Elevated energy persists | Prices stay high | 3.0%-3.5% |
| Prolonged disruption | Prices keep rising | Above 3.5% |
The FERS cap is now a real factor. If the final COLA lands above 3%, FERS retirees get CPI-W minus 1 percentage point. A 3.2% COLA means CSRS and Social Security recipients get 3.2% while FERS retirees get 2.2%. A 3.5% COLA means FERS gets 2.5%. Watch July and August CPI-W releases closely. Those two months will tell us whether this is a sustained inflation trend or a transient spike that fades.
Key Takeaways
- The 2027 COLA running count through March 2026 CPI-W is approximately 2.0% (Q3 2025 baseline: 317.265)
- March inflation jumped to 3.3% year-over-year, pushing projections upward to 2.8%-3.3%
- Energy prices tied to Middle East conflict are the main variable -- the summer months will determine the final number
- FERS retirees face the cap if the COLA exceeds 3%: they receive the full percentage minus 1 point
- Final COLA announced in mid-October 2026 after Q3 CPI-W data
- Next CPI-W release (April 2026 data): May 13, 2026
Monthly COLA tracker
This table updates as new CPI-W data is released, typically around the 13th of each month.
| Month (2026 data) | CPI-W | Change from Q3 2025 Baseline (317.265) | Running COLA Count | Release Date |
|---|---|---|---|---|
| January | 317.942 | +0.21% | 0.2% | Feb 13, 2026 |
| February | 319.422 | +0.68% | 0.7% | Mar 11, 2026 |
| March | 323.500 | +1.97% | ~2.0% | Apr 10, 2026 |
| April | Pending | - | - | May 13, 2026 |
| May | Pending | - | - | Jun 11, 2026 |
| June | Pending | - | - | Jul 11, 2026 |

| August | Pending | - | - | Sep 10, 2026 |
| September | Pending | - | - | Oct 14, 2026 |
Only July, August, and September matter for the final COLA calculation. The earlier months are useful for tracking the trend, but the official COLA is based on the average CPI-W for Q3 2026 compared to the Q3 2025 baseline of 317.265.
Current projections: where the 2027 COLA might land
| Source | 2027 COLA Projection | Date of Projection |
|---|---|---|
| FedSmith (updated range) | 2.8%-3.3% | April 2026 |
| Congressional Budget Office (CBO) | 3.1% | 2026 |
| Senior Citizens League (TSCL) | 2.8% | April 2026 |
| March CPI-W running count | ~2.0% | April 2026 |
The range has widened since January. That's not unusual -- Q1 data moves around a lot, and the summer months are what actually count. What has changed is the direction: the risk is now tilted toward higher inflation, not lower. If that holds through Q3, FERS retirees will almost certainly be in the cap zone again.
If the COLA lands between 2% and 3%, FERS retirees get capped at 2%. If it comes in above 3%, FERS gets the COLA minus 1 percentage point. Only if it's 2% or below do FERS retirees get the full amount.
How the COLA calculation works
The federal retiree COLA is based on the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W), published monthly by the Bureau of Labor Statistics.
Here's the formula:
- Take the average CPI-W for July, August, and September 2026
- Compare it to the Q3 2025 baseline (average CPI-W for July-September 2025 = 317.265)
- The percentage increase is the COLA for CSRS retirees and Social Security recipients
- FERS retirees get a modified version based on the cap rules
FERS COLA cap rules
| If CPI-W increase is... | FERS COLA is... |
|---|---|
| 2% or less | Full amount |
| Between 2% and 3% | Capped at 2% |
| Above 3% | CPI-W increase minus 1 percentage point |
Recent COLA history
| Year | Full COLA (CSRS/SS) | FERS COLA | Difference |
|---|---|---|---|
| 2026 | 2.8% | 2.0% | -0.8% |
| 2025 | 2.5% | 2.0% | -0.5% |
| 2024 | 3.2% | 2.2% | -1.0% |
| 2023 | 8.7% | 7.7% | -1.0% |
| 2022 | 5.9% | 4.9% | -1.0% |
In 5 of the last 5 years, FERS retirees got less than the full COLA. The only way FERS gets the full COLA is if inflation stays at or below 2%, which hasn't happened since 2020.
Why the FERS COLA cap matters more than you think
The gap between CSRS and FERS COLAs looks small in any single year. But it compounds.
Over 20 years of retirement with an average 0.7% annual gap (typical based on recent history), a FERS retiree's pension loses about 13% of its purchasing power relative to a CSRS retiree's pension. On a $3,000/month pension, that's roughly $390/month in lost purchasing power by year 20.
This is the hidden cost of FERS that most retirement planning guides don't emphasize enough. Your pension is partially inflation-protected, not fully. The TSP and Social Security fill some of that gap, but only if you've planned for it.
Use the FERS Retirement Calculator to model different COLA scenarios and see how the cap affects your pension over 10, 20, and 30 years of retirement.
What this means for your retirement planning
If you're still working, the COLA cap is one more reason to maximize your TSP contributions. Your FERS pension won't fully keep up with inflation. Your TSP balance, invested in stock funds, has historically outpaced inflation over the long term.
If you're already retired, the COLA is set. You can't change it. But you can adjust your spending and withdrawal strategy based on what's coming. A 2% COLA on a $36,000 annual pension adds $720/year, or $60/month. A 3% COLA adds $1,080, but FERS retirees would only get 2% ($720) while CSRS retirees get the full $1,080. If the COLA comes in at 3.2%, CSRS retirees get $1,152 more per year while FERS retirees get $792 -- a $360 annual gap on a $36,000 pension.

Frequently asked questions
What is the 2027 COLA estimate for federal retirees?
As of March 2026 CPI-W data, the running count is approximately 2.0%. FedSmith projects the final 2027 COLA in the 2.8%-3.3% range after a March inflation spike. The Senior Citizens League predicts 2.8% and the CBO projects 3.1%. The final number will be announced in mid-October 2026, based on the average CPI-W for July through September 2026.
How is the federal retiree COLA calculated?
The average CPI-W for July through September 2026 is compared to the Q3 2025 baseline of 317.265. The percentage increase becomes the COLA for CSRS retirees and Social Security. FERS retirees get a reduced COLA if the increase exceeds 2%.
Why do FERS retirees get a smaller COLA than CSRS retirees?
FERS COLAs are capped. If the CPI-W increase is 2% or less, FERS gets the full amount. If between 2% and 3%, FERS is capped at 2%. If above 3%, FERS gets the CPI-W increase minus 1 percentage point. In 2026, CSRS got 2.8% but FERS only got 2.0%.
When will the 2027 COLA be announced?
Mid-October 2026, after the September CPI-W data is released. Monthly CPI-W updates come out around the 13th of each month.
How does the FERS COLA cap affect my pension over time?
The cap means your pension loses purchasing power during moderate inflation (2-3%). Over 20 years with a typical 0.7% annual gap, a FERS pension loses about 13% of its relative purchasing power. Use the FERS Retirement Calculator to model this for your specific pension amount.
