Most retirees expect their income to rise when prices rise. For many federal retirees, that’s only partly true.
Social Security, a FERS pension, and the FERS supplement each follow their own inflation rules. The same inflation rate can give you a full raise on one check, a smaller raise on another, and no raise at all on a third.
If your retirement plan assumes all of your income keeps pace with inflation, it may be overstating what your money will actually buy.
Why This Matters Right Now
Inflation has been running hot this year. In August 2026, the CPI-W, the index used to calculate cost-of-living adjustments (COLAs), rose 3.5% over the past 12 months. Energy drove much of it, with gasoline up 27.4% year over year.
The Federal Reserve took notice. On September 16, it raised its benchmark rate to a range of 3.75% to 4%, noting that inflation remains elevated.
So the real question isn’t just “Will I get a raise next year?” It’s this:
Which parts of my income get a raise, how much, and starting when?
How the Social Security COLA Works
First, an important point: the 2027 Social Security COLA has not been announced yet. Any number you see today is a projection.
The Social Security Administration (SSA) calculates the COLA using the CPI-W. It compares the average for July, August, and September of this year with the same three-month average from the last year a COLA took effect.
That means August’s 3.5% reading is a strong signal, but it isn’t the final answer. September still counts. The September inflation report is scheduled for release on October 14, 2026, and the COLA announcement is expected soon after.
For context, the 2026 COLA was 2.8%.
Here’s what matters most: Social Security receives the full inflation adjustment. No cap. No age requirement.
How FERS COLAs Work
FERS uses the same inflation index. But it applies a different formula and an age rule that Social Security doesn’t have.
The FERS formula (often called the “diet COLA”)
For eligible FERS retirees, the pension adjustment works in tiers:
- Inflation of 2% or less: your COLA matches inflation.
- Inflation above 2%, up to 3%: your COLA is 2%.
- Inflation above 3%: your COLA is inflation minus 1 percentage point.
You can see the difference in this year’s numbers. For 2026, the Office of Personnel Management (OPM) applied a 2.8% increase for CSRS retirees and 2% for FERS retirees. Same inflation. Different raise.
The under-62 rule
This is the rule that surprises many new retirees. According to OPM, FERS retirees under age 62 generally do not receive COLAs.
In plain English: if you retired under regular FERS rules before 62, your pension typically stays at the same dollar amount until you turn 62, even if prices keep climbing.
Who is exempt
The under-62 rule doesn’t apply to everyone. OPM’s exceptions include:
- Survivor annuitants (spouse, former spouse, or insurable interest)
- Certain disability retirees
- Those who retired under special provisions for law enforcement officers, firefighters, Capitol Police, and air traffic controllers
- Certain military reserve technicians and Joint Payroll Office FERS Special annuitants
Also note: if part of your annuity was earned under CSRS, that portion follows CSRS rules and can receive COLAs before 62.
The FERS supplement never gets a COLA
If you retired before 62 with an immediate, unreduced annuity, you may receive the FERS annuity supplement. It’s designed to bridge the gap until you’re eligible for Social Security.
OPM is clear on this point: FERS COLAs apply only to the basic annuity, not the supplement. The supplement stays flat the entire time you receive it, and it ends at 62.
Same Inflation, Four Outcomes: A Hypothetical Example
This example is hypothetical. It assumes a 3.5% inflation adjustment for illustration only. The actual 2027 COLA has not been announced.
| Income source | Monthly amount | Adjustment | New amount |
|---|---|---|---|
| Social Security | $2,400 | 3.5% | $2,484 (+$84) |
| FERS annuity, retiree age 63 | $3,000 | 2.5% | $3,075 (+$75) |
| FERS annuity, regular retiree age 57 | $3,000 | 0% | $3,000 (+$0) |
| FERS supplement, retiree age 57 | $1,200 | 0% | $1,200 (+$0) |
Look at the 57-year-old retiree. Their $4,200 in monthly income doesn’t move. If their living costs rise 3.5%, they’d need about $147 more each month just to stay even.
And the gap compounds. If inflation averaged 3.5% for five years, a flat income would buy roughly 16% less by the end of that stretch.
The takeaway: your retirement income plan should not assume that every dollar of income will receive the same inflation adjustment.
The 2025 Early-Retirement Wave Makes This Timely
In 2025, many federal employees left service earlier than they planned. OPM reported that roughly 154,000 employees resigned under the Deferred Resignation Program, while others left through Voluntary Early Retirement Authority (VERA) and other programs.
VERA opened retirement to younger employees: those at least age 50 with 20 years of service, or any age with 25 years. For VERA retirees, the FERS supplement generally doesn’t begin until they reach their Minimum Retirement Age.
Not everyone who left in 2025 is affected the same way. Some are over 62. Some retired under special provisions. Some deferred their annuity.
But for a regular FERS retiree in their 50s, 2027 may be the first year of higher inflation without a pension raise. Many of those decisions were made when inflation was cooler, so the assumptions behind them deserve a fresh look.
Healthcare: The Cost That Doesn’t Wait
Inflation isn’t the only pressure on your budget. Healthcare costs tend to rise on their own schedule.
Medicare Part B premiums come directly out of Social Security checks. The standard premium is $202.90 per month in 2026. The Medicare Trustees have projected about $209.50 for 2027, but that’s an estimate. The official number is expected later this fall. Higher-income retirees also pay income-related surcharges on top of the standard premium.
Before 65, federal retirees also carry FEHB premiums. Either way, healthcare deserves its own line in your plan, not just a spot inside a general inflation estimate.
Your Inflation Gap Review: 10 Questions to Ask
Understanding the rules is step one. Applying them to your own numbers is where the real clarity comes from.
If you’re approaching retirement, or already retired, and you’re not sure how inflation, Social Security, your pension, taxes, and healthcare costs fit together, a personalized review can help you see where the gaps or uncertainties are. Schedule a Wealth Clarity Call and we’ll walk through it with you.
Whether you review on your own or with help, start with these questions:
- Which income sources adjust for inflation? List every one: Social Security, FERS annuity, supplement, military retired pay, other pensions, annuities, and rental income.
- Which don’t? Mark each source that stays flat, and for how long.
- When does each adjustment start? For regular FERS retirees, that’s generally age 62.
- What share of my income is non-adjusting? The higher the percentage, the more inflation matters to you.
- What if inflation stays elevated? Run your plan at several inflation rates, not one average.
- Are healthcare costs built in realistically? Include FEHB before 65, Medicare at 65, and possible income-related surcharges.
- How does my Social Security timing fit? Your claiming age affects how much of your lifetime income is fully inflation-adjusted, and it connects directly to the supplement ending at 62.
- How flexible are my TSP and investment withdrawals? Know what happens if you need to draw more when prices rise.
- How do taxes affect my real income? Bigger withdrawals can mean higher taxable income. What matters is what you keep.
- Which original assumptions need a stress test? Revisit your inflation rate, spending needs, retirement age, investment returns, and how long your money needs to last.
Practical Ways to Manage an Inflation Gap
Every situation is different, but these planning approaches help many retirees think more clearly about the gap.
Sort your income by inflation protection.
Group your income into three buckets: adjusts fully, adjusts partially, and doesn’t adjust. This simple exercise often reveals more than a complex projection.
Treat the pre-62 years as their own phase.
If your pension and supplement are flat until 62, budget that window separately. Decide ahead of time which resources will absorb rising costs during those years.
Give your TSP a clear job.
Many retirees use savings to supplement fixed income when prices rise. Having a plan for that, instead of reacting in the moment, protects both your balance and your peace of mind.
Plan the age-62 transition on purpose.
At 62, the supplement ends and pension COLAs generally begin. That’s a natural point to coordinate your Social Security decision with the rest of your income.
Look at taxes across several years, not just one.
The timing and order of withdrawals can affect your taxes and, for some retirees, Medicare premiums. Review this with a qualified tax professional.
Update your plan every October.
Once the COLA is announced, run the new number through each income source separately. Your plan is only as good as its latest assumptions.

The Real Goal: Purchasing Power
Retirement isn’t only about how much you’ve saved. It’s about how reliably that money can produce purchasing power over time.
Two retirees with the same pension and the same TSP balance can live very different retirements, depending on how much of their income keeps pace with rising prices.
The earlier you spot an inflation gap, the more options you have to plan around it. When the 2027 COLA is announced this October, don’t just look at the headline number. Run it through each of your income sources and see what your raise really looks like.
