Two federal retirement numbers arrived within weeks of each other this fall, and they point in opposite directions. The 2027 cost-of-living adjustment for FERS retirees is 2.6%. The average share of the FEHB premium that enrollees pay is rising 10.9%. One number raises your income. The other raises a bill you cannot skip. The question most retirees are asking is simple: does the first cover the second?
The honest answer is that it depends on three things: your annuity, your age and the plan you choose. A retiree with a larger annuity and a Self Only plan may come out slightly ahead. A retiree with a modest annuity and a Self Plus One plan may come out behind. A FERS retiree under 62 receives no COLA at all, yet still pays the higher premium. This guide gives you a quick test you can run in five minutes, plus worked examples that show how different the outcomes can be.
Open season for plan year 2027 runs from November 9 to December 14, 2026, so there is still time to act on what you learn. This article is written for federal employees and retirees in Puerto Rico, and for the small business owners among them, many of whom run a family business alongside a federal pension. By the end you will know how to compare the two numbers fairly, where the real pressure points are and which steps are worth taking before the window closes.

The Scoreboard: Two Numbers, One Budget
Before running any scenario, it helps to know exactly what each number measures. They sound similar, but they are not measured against the same base, and that difference explains most of the confusion.
What the 2.6% COLA Applies To
The Social Security Administration announced a 3.6% cost-of-living adjustment on October 14, 2026, and that full 3.6% applies to Social Security and CSRS. FERS uses a different formula: when the inflation measure exceeds 3%, FERS subtracts one percentage point, which gives 2.6%, as Federal News Network reported. It applies to the basic annuity only, and it generally starts at age 62. The first payment with the new rate arrives in January 2027.
What the 10.9% Premium Increase Applies To
The 10.9% figure is the average increase in the enrollee share of the premium across FEHB and PSHB plans, according to OPM’s open season highlights. It is not the increase in the total premium. The overall average premium, which includes the government’s share, rises 9.3%, and the government’s share rises 8.6%. Because the government pays the larger share, a smaller increase in the total translates into a bigger percentage increase for the enrollee.
Why Averages Hide Your Real Number
An average combines every plan and every enrollment type. Your increase depends on your plan and your tier. Federal Pension Advisors, reading OPM’s rate charts published on September 30, 2026, reports that the Blue Cross Standard Option annuitant share rises to $443.41 a month for Self Only and $974.76 for Self Plus One. That is an increase of roughly $35 and $85 a month, respectively. Some plans rose far more, and some options were flat or lower. That is why checking your own plan matters more than watching the headline.
Why the Two Numbers Do Not Cancel Out
It is tempting to subtract 2.6 from 10.9 and conclude that every retiree falls behind by 8.3%. That arithmetic is wrong, because the percentages apply to different amounts.
Percentages on Different Bases
The COLA applies to your whole annuity, which is a large number. The premium percentage applies only to your premium share, which is a much smaller number. A 2.6% raise on a $3,000 annuity is $78. A 10.9% increase on a $780 premium is about $85. What matters is the dollar comparison, not the percentage comparison.
The Dollar Comparison Is What Counts
For a single retiree, the test is simple: new COLA dollars minus new premium dollars. If the result is positive, the raise covers the premium increase with something left over. If it is negative, the premium takes more than the COLA gives. The size of the annuity decides which side you land on, which is why the same two numbers produce very different outcomes for different households.
A Five-Minute Break-Even Test
To find your break-even annuity, divide the monthly premium increase by the COLA rate. For a Self Only enrollee in the Blue Cross Standard Option, $35.38 divided by 0.026 is about $1,361, so an annuity near $1,400 or more covers the increase. For Self Plus One, $84.52 divided by 0.026 is about $3,251, so an annuity near $3,250 or more is needed. These are simple estimates, and they assume you receive the full COLA. Your own plan and annuity will change the result.
Three Retirees, Three Different Outcomes
Numbers become clearer when they belong to people. The three examples below are hypothetical. They use the Blue Cross Standard Option increases cited above and the 2.6% FERS COLA, with the COLA rounded down to the whole dollar.
Elena: Over 62, Self Only
Elena is 64 and receives a $2,400 monthly FERS annuity. Her COLA is 2.6% of $2,400, or $62.40, which rounds down to $62. Her Self Only premium rises $35.38. She comes out $26.62 ahead each month, or about $319 over the year. The raise covers the increase with a little room to spare.
Roberto: Over 62, Self Plus One
Roberto is 66 with a $3,000 annuity and covers his spouse. His COLA is $78. His Self Plus One premium rises $84.52. He ends up $6.52 behind each month, about $78 over the year. His raise and his increase almost cancel, and a plan with a lower premium could easily tip the result back in his favor.
Wanda: Retired at 57, Not Yet 62
Wanda retired at 57 and is now 58, with a $2,800 annuity and a Self Plus One plan. FERS retirees under 62 generally receive no COLA on their basic annuity, so her adjustment is $0. She still pays the $84.52 increase. She is $84.52 behind each month, or $1,014 for the year. Her situation shows why the age rule matters more than the headline percentage.
A CSRS Comparison
For reference, a CSRS retiree with a $3,000 annuity receives the full 3.6%, or $108. After the same $84.52 increase, that retiree is $23.48 ahead each month. The gap between a FERS and a CSRS retiree with identical annuities is a feature of the law, not a miscalculation, and it has appeared in each of the past several years.
Who Feels the Squeeze the Most
Averages describe the middle of the group. The pressure falls hardest on a few specific situations, and it helps to know whether you are in one of them.
Retirees Under 62
FERS retirees under 62, along with those receiving the FERS supplement, do not receive a COLA on those amounts. They face the premium increase in full and see no offsetting adjustment. Some exceptions apply, such as survivors, certain disability retirees and law enforcement, firefighter and similar retirees, so confirm your category with OPM before assuming.
New Retirees in 2026
The first COLA after retirement is prorated. Generally, a retiree receives one-twelfth of the adjustment for each full month retired during the year. Someone who retired in the second half of 2026 may receive only a fraction of the 2.6%, while the premium increase applies in full from January. The first year after retirement is often the tightest.
Families on Self Plus One
The Self Plus One tier can cost more per month than Self Only by a large margin, and in some plans it can even cost more than Self and Family. A family of two on a Self Plus One plan may find that the tier choice matters more than the plan. Compare all three tiers for your household during open season, as the cheaper-looking option is not always the cheapest.
Closing the Gap: What You Can Do Before December 14
You cannot change the COLA. You can change your plan, your tier and parts of your overall financial picture. These are the levers worth considering.
Mark the Dates That Matter
Open season runs from November 9 through December 14, 2026, and changes take effect for annuitants on January 1, 2027. If you do nothing, you stay in your current plan at the new price. Setting a calendar reminder for the first week of December leaves time to compare plans, gather any family documents and confirm your election before the last day, when websites and phone lines are busiest.
Compare Plans on Total Cost
The premium is only one cost. Deductibles, copays, prescription tiers and out-of-pocket maximums determine what you actually spend. A plan with a lower premium and a higher deductible can cost more for someone who uses care often. The reverse can also be true. Using last year’s claims as a guide, estimate the total cost under two or three plans. When you shop for health insurance in Puerto Rico as a federal enrollee, confirm which plans serve your area for 2027, since OPM’s Puerto Rico plan page lists the options available on the island.
Right-Size Your Coverage Tier
Review who is actually covered. A child who has aged out of eligibility or a spouse who now has other coverage can change the tier you need. Changes require documentation, and adding family members now requires supporting documentation, so gather certificates and records before you make changes.
Coordinate With Medicare
Retirees who are eligible for Medicare may find that pairing Part B with an FEHB plan changes the value of each plan’s benefits. Some plans reduce or waive certain costs for enrollees who have Part B. The Part B premium for 2027 had not yet been announced when this article was written, so weigh that number when it arrives. A licensed professional who knows your situation can help you weigh the tradeoffs.
Use a Calculator, Not a Guess
Build a short spreadsheet or use a retirement planning calculator to compare your new monthly income with your new fixed costs. Include the COLA, the premium change, Medicare costs and any supplemental coverage. Seeing the net monthly change in one number turns a vague worry into something you can manage.
When the Pension Is Only Part of the Picture
For many federal retirees in Puerto Rico, the annuity is one income stream among several. Looking at it alone can overstate or understate how a premium increase will feel.
TSP and Other Savings
Money in the Thrift Savings Plan or other accounts can cover a gap without disrupting the rest of your plan. The key is to decide in advance how much you will withdraw and when, instead of drawing from savings in response to every bill. A steady, documented withdrawal plan is easier to sustain than ad hoc withdrawals. Taxes matter here, too, and a plan for tax efficient retirement in Puerto Rico households can use will consider which accounts to draw from first and how Puerto Rico and federal rules interact.
If You Also Run a Small Business
Many federal employees and retirees in Puerto Rico own or help run a family business: a small shop, a rental, a consulting practice or a service company. Business income can help absorb a premium increase, but it also needs planning. It can affect your taxes, and if you are under the minimum retirement age and receive the FERS supplement, earnings above the annual limit, $25,560 for 2027, can reduce the supplement. Keeping a cash reserve for the business and a separate reserve for your household helps one side of the family budget avoid draining the other.
Setting Priorities
When several costs rise at once, it helps to rank them. Health coverage, housing, food, taxes and debt payments come first. Discretionary spending and large purchases come second. A short written priority list, reviewed once a year, makes it easier to decide where an unexpected increase should come from.
Questions Worth Asking Before You Decide
A short list of questions can turn a stressful decision into a structured one.
Six Questions for Your Next Conversation
Bring these to a benefits counselor or advisor:
- What is my exact COLA in dollars, including any proration for my retirement date?
- What is my exact premium change in dollars for my current plan, and for each alternative plan?
- Does my age or category mean I receive a reduced COLA or none?
- Would a different tier or plan lower my total cost, not just my premium?
- How will Medicare Part B affect the value of my FEHB plan?
- Which accounts should I draw from first if I need to cover a shortfall?
Where Professional Guidance Helps
Federal benefits sit alongside Puerto Rico tax rules, Medicare and personal goals, and the interactions are hard to see from one side. A planner who works with federal employee retirement in Puerto Rico clients can map those pieces together and model a few scenarios. A qualified professional can also review the details specific to you, such as survivor benefits, your retirement date and your family situation. For a broader review of your income, costs and risks, retirement planning services in Puerto Rico that look at the whole picture can be more useful than a single-topic answer.
What to Do This Week
Pull your 2027 premium for your current plan from the OPM plan information, calculate your COLA in dollars, subtract one from the other and write down the result. That single number tells you whether you are ahead, even or behind. If you are behind, spend an hour comparing at least one alternative plan before the window closes.

Conclusion
The 2.6% COLA and the 10.9% average premium increase are both real, but neither tells you what will happen to your budget. The answer comes from dollars, not percentages: your COLA in dollars minus your premium increase in dollars. For some retirees that number is modestly positive. For others, especially those under 62 or on a Self Plus One plan, it is negative.
The encouraging part is that open season gives you a real choice. Comparing plans on total cost, right-sizing your tier and checking how Medicare fits can change the outcome before January. Pair that with a simple written plan for your other income and expenses, and a premium increase becomes a manageable adjustment, not a surprise.
