Key Takeaways
-
Even though you can keep your Federal Employees Health Benefits (FEHB) coverage into retirement, the cost structure often changes more than most retirees anticipate.
-
Understanding how premiums, Medicare integration, and survivor benefits affect your FEHB expenses is critical to protecting your retirement budget.
Why FEHB Still Matters in Retirement
The Federal Employees Health Benefits (FEHB) Program remains one of the strongest health coverage options for public sector retirees. It offers continued access to group rates, extensive plan choices, and guaranteed coverage into old age. However, what surprises many is that the cost of maintaining FEHB is not static after you retire.

The Shift in Premium Payments After Retirement
One of the first shocks comes when you realize how premium payments change once you retire. As an active employee, your FEHB premiums are paid with pre-tax dollars. Upon retirement, premiums are deducted from your annuity on an after-tax basis.
This shift makes a bigger difference than you might expect:
-
Your tax savings decrease.
-
Your take-home income reduces by the amount of tax you now have to pay on those dollars.
-
Your budget might feel tighter than you planned.
Understanding this tax impact ahead of retirement can help you better estimate your “real” cost of keeping FEHB in retirement.
Annual Premium Increases Are Often Overlooked
Many retirees are caught off guard by the steady climb of FEHB premiums. In 2025, for instance, FEHB premiums rose by an average of 11.2% compared to 2024. While the government continues to cover a significant portion of the premium, your share inevitably increases with each passing year.
The typical pattern looks like this:
-
Premium adjustments are announced each fall for the next calendar year.
-
Increases tend to range from 5% to 15% annually, depending on the plan.
-
Some years, premium hikes outpace the cost-of-living adjustments (COLAs) added to your retirement annuity.
Not planning for these yearly cost escalations can seriously strain your financial plan over a 20- or 30-year retirement.
How Medicare Integration Affects Your Costs
Once you reach age 65, Medicare becomes a key part of your healthcare strategy. How you coordinate FEHB with Medicare can significantly impact your expenses.
Most public sector retirees enroll in Medicare Part A (hospital insurance) because it is usually premium-free if you have enough work credits. However, Part B (medical insurance) comes with a monthly premium—and it is optional.
Choosing whether or not to enroll in Medicare Part B is a major decision because:
-
If you enroll, your out-of-pocket costs for services can decrease.
-
Some FEHB plans reduce deductibles, copayments, and coinsurance when you have both FEHB and Medicare.
-
However, you must pay both your FEHB premium and your Medicare Part B premium, adding to your monthly expenses.
In 2025, the standard Medicare Part B premium is $185 per month, not including income-related adjustments. That’s a considerable additional cost that you must factor into your retirement healthcare budget.
What Happens to FEHB When a Retiree Passes Away
Another cost trap involves survivor benefits. To allow your spouse to continue FEHB after your death, you must:
-
Elect a survivor annuity at retirement.
-
Maintain the appropriate level of FEHB coverage (Self and Family or Self Plus One).
Without these elections, your spouse loses access to FEHB forever. Survivor annuities typically reduce your own retirement annuity—often by around 10% of your full annuity amount—which is an added “cost” you need to understand well before you retire.
FEHB vs. Other Health Insurance Options
Some retirees wonder whether switching to private health insurance after retirement could save money. In reality, leaving FEHB for a private health plan often comes with significant risks:
-
Loss of guaranteed group rates.
-
Less comprehensive coverage.
-
Difficulty re-enrolling in FEHB later, especially outside Open Season or a qualifying life event.
Once you drop FEHB, you might not be able to get it back—a choice that could haunt you later when healthcare costs are highest.
Common Misconceptions About FEHB Costs
Several misunderstandings persist about FEHB in retirement. Clearing them up can save you thousands of dollars over time.
1. “My premium stays the same after I retire.”
Not true. Your share of the premium continues to rise each year. Retirees sometimes notice premium hikes even more because they are no longer getting annual salary increases.
2. “Medicare will replace my FEHB.”
Incorrect. FEHB continues to be your primary health insurance, while Medicare acts as secondary (if you enroll in Part B). You generally want to keep both for the best protection.
3. “I can change FEHB plans anytime I want.”
Changes are typically only allowed during the annual Open Season (November to December) or after a qualifying life event, such as marriage or divorce.
Planning Tips to Manage FEHB Costs After Retirement
Smart planning now can help you avoid being blindsided later. Here are some important strategies:
-
Project premium increases: Assume at least a 5%-10% annual increase when forecasting future expenses.
-
Account for taxes: Remember that your FEHB premiums will be after-tax costs.
-
Consider Medicare Part B carefully: Weigh the added monthly cost against the savings in out-of-pocket healthcare expenses.
-
Protect survivor benefits: Elect the appropriate survivor annuity if you want your spouse to keep FEHB after your death.
-
Use Open Season wisely: Review available plans each year to see if a lower-cost option with better Medicare integration exists.
The Timeline: What Happens and When
Understanding key dates can also help you better manage FEHB costs:
-
Retirement: Premiums shift to after-tax.
-
Age 65: Medicare eligibility begins; decide on enrolling in Part A and/or Part B.
-
Every November-December: Open Season provides an opportunity to review and change FEHB plans.
-
Upon death (if married): Survivor benefit elections determine whether your spouse keeps FEHB.
Mapping out these events ensures you are not making hasty or expensive decisions.
Why FEHB Is Still Worth It
Despite the costs, FEHB remains one of the best retiree health coverage options available. Compared to the individual insurance market, FEHB plans typically offer:
-
Lower out-of-pocket costs.
-
Comprehensive nationwide networks.
-
Consistent benefits into very old age.
Giving up FEHB without careful analysis could expose you to much higher health expenses in later years.
Managing Healthcare Costs for a Secure Retirement
Retaining FEHB is only one piece of the puzzle. To truly protect your retirement income, consider building a broader healthcare strategy that includes:
-
Health Savings Accounts (HSAs) before retirement.
-
Budgeting for Medicare Part B premiums.
-
Understanding long-term care insurance options.
-
Setting aside funds for annual premium increases.
Healthcare is one of the largest expenses in retirement—larger even than housing for some retirees. A proactive approach ensures that your retirement funds last as long as you need them to.
Protect Your Healthcare Coverage With Smart Planning
The truth is that FEHB costs after retirement can easily catch you off guard—but they don’t have to. With early planning, clear understanding, and strategic choices, you can retain the exceptional coverage FEHB offers without sacrificing your financial security.
