Trying to sort out FEHB and Tricare can make your head spin fast. A lot of people ask the same thing: Do I need both? Can I keep FEHB with Tricare? Which one should my spouse use? If you're a military retiree, a federal worker, or both, this choice affects your monthly budget and your access to care.
Here’s the good news: you usually do not have to pick just one forever. In many cases, you can keep both, use one, or switch during Open Season. The hard part is knowing what makes sense for your family. That’s why the easiest way to get your exact numbers is to use this free FEHB guide calculator. It helps you compare costs and avoid guessing.
FEHB and Tricare basics: what each plan does
Before we compare Tricare vs FEHB, let’s make sure we’re talking about the same things.
What FEHB is
FEHB stands for the Federal Employees Health Benefits Program. It is the main health insurance program for federal workers and many federal retirees. You pick a plan from a menu of options, and the government pays a big share of the premium.
With FEHB, your cost depends on:
- The plan you choose
- Self Only, Self Plus One, or Self and Family coverage
- Whether you are an employee or retiree
- The plan’s deductible, copays, and network
You can review official plan rules at OPM’s FEHB page and broader benefit info at OPM.gov.
What TRICARE is
TRICARE is the health program for uniformed service members, retirees, and eligible family members. Military retirees often use:
- TRICARE Prime
- TRICARE Select
- TRICARE For Life at age 65 with Medicare Part A and Part B
TRICARE costs are often much lower than FEHB premiums, but coverage rules work differently. Networks, referrals, pharmacy rules, and overseas access can vary. The official source is TRICARE.mil. Military families can also get plain-English help from Military OneSource.
Why this question matters so much
For a federal employee health insurance military retiree, the gap in monthly cost can be huge. A FEHB family plan can cost several hundred dollars per month. Some TRICARE options cost far less.
But lower premium does not always mean better fit. FEHB may offer:
- Wider provider choice in some areas
- Better coverage for certain doctors or hospitals
- Easier access for family members who are not TRICARE-eligible
- A way to keep FEHB into retirement if you meet the rules
If you’re close to retirement, also read our guide on can you keep FEHB when you retire? The 5-year rule explained. That rule matters a lot here.
Can I keep FEHB with Tricare? Yes, but the smart answer depends on timing
The short answer to can I keep FEHB with Tricare is yes. If you are eligible for both, you can usually stay enrolled in FEHB and also have TRICARE. You can even suspend FEHB in some retirement cases and come back later, which is a big advantage.
While you are still a federal employee
If you are an active federal employee and also a military retiree with TRICARE, you generally have a few choices:
- Enroll in FEHB and keep TRICARE
- Use only TRICARE and decline FEHB
- Cover one family member under FEHB and others under TRICARE, depending on eligibility
Important point: if you decline FEHB as an employee, that may affect your ability to carry FEHB into retirement later. To continue FEHB in retirement, you usually must:
- Retire on an immediate annuity, and
- Be enrolled in FEHB for the 5 years right before retirement, or since your first chance to enroll
That is why many people keep FEHB at least late in their career, even if TRICARE is cheaper now.
After you retire from federal service
Once you retire from your civilian federal job, you may be able to suspend FEHB if you are covered by TRICARE or another qualifying program. Suspension is better than cancellation.
Why? Because suspension may let you re-enroll in FEHB later. If you cancel, getting it back is much harder or impossible in many cases.
This is one of the biggest planning points in the whole FEHB and TRICARE discussion.
Example: why the 5-year rule changes the answer
Let’s say Mark is 57, a GS-12 federal employee, and a retired Army E-7. He has TRICARE Select. FEHB Self Plus One would cost him about $280 per pay period for a mid-range plan, or roughly:
- $280 × 26 pay periods = $7,280 per year
His TRICARE Select retiree family enrollment fee might be around $365 per year, plus cost-shares.
If Mark drops FEHB now to save money, that could save thousands each year. But if he retires from federal service in 4 years and has not met the FEHB 5-year rule, he may lose the right to carry FEHB into retirement.
That is a very expensive mistake.

Tricare vs FEHB: which one is better for military retirees and spouses?
This is where things get personal. Tricare vs FEHB is not really about which one is “best” for everyone. It is about which one fits your doctors, your family, and your retirement plan.
When TRICARE often wins
TRICARE often looks better on pure cost.
For many military retirees, TRICARE premiums or enrollment fees are much lower than FEHB premiums. That can free up money for TSP savings, debt payoff, or just breathing room in your budget.
TRICARE may be a strong fit if:
- You already use military or TRICARE network providers
- Your family is fully TRICARE-eligible
- You want lower monthly costs
- You are comfortable with referrals or network rules
When FEHB may still be worth it
FEHB can still make sense if:
- Your favorite doctors do not take TRICARE
- Your spouse or child is not TRICARE-eligible
- You want more plan choices
- You are protecting your right to keep FEHB in retirement
- You expect to suspend FEHB later, not lose it forever
A lot of FEHB military spouse questions come down to eligibility. A military spouse may be covered under TRICARE because of the service member’s retirement. But if family status changes due to divorce, remarriage, or age-out rules for children, the best setup can change fast.
Spouse angle: one size does not fit every family
Here’s a common setup:
- Federal employee spouse has access to FEHB
- Military retiree spouse has TRICARE
- Children may be eligible for TRICARE
- The family is trying to avoid paying for duplicate coverage
In that case, some families choose:
- FEHB Self Only for the federal employee
- TRICARE for the military retiree and children
Others choose:
- No FEHB now
- TRICARE for everyone eligible
- Then revisit FEHB before federal retirement if needed for the 5-year rule
The right answer depends on ages, retirement timing, and whether you need FEHB later.

FEHB military spouse and dual-eligibility scenarios
Let’s look at a few common situations that cause confusion.
Scenario 1: Federal employee is the military retiree
You served 20 years, retired from the military, and now work as a GS employee. You have TRICARE and access to FEHB.
Main question: should you pay for FEHB now?
Things to weigh:
- FEHB premium cost today
- Whether you need the FEHB 5-year rule for retirement
- Whether TRICARE already covers your family well
- Whether your doctors accept TRICARE
Scenario 2: Federal employee is married to a military retiree
This is a classic FEHB military spouse case. The federal employee can enroll in FEHB. The spouse and kids may have TRICARE through the military retiree.
Main question: should the federal employee carry family FEHB, self-only FEHB, or no FEHB?
This often comes down to whether the federal employee wants to preserve FEHB for retirement. If yes, Self Only FEHB may be the lowest-cost way to keep that door open.
Scenario 3: One spouse is nearing federal retirement
This is where mistakes happen. If you are 2 to 5 years from federal retirement, the answer may be very different than it was 10 years earlier.
A cheap choice now can close off FEHB later. That is why many people run the numbers more than once. The free FEHB guide calculator is useful here because it helps you compare current premiums with long-term retirement value.

Practical examples with real numbers
Let’s put some simple numbers on this.
Example 1: Retired E-7 now working as GS-11
James is a retired Army E-7 and now a GS-11 employee. He has a spouse and one child.
Option A: FEHB Self and Family
- Premium: about $340 per pay period
- Annual cost: $340 × 26 = $8,840
Option B: TRICARE Select family
- Annual enrollment fee: about $365
- Cost-shares: let’s estimate $1,200 for the year
- Total estimated annual cost: $1,565
Estimated savings with TRICARE:
- $8,840 - $1,565 = $7,275 per year
That’s real money. But if James plans to retire from federal service in 3 years and has not had FEHB for 5 years, dropping FEHB could cost him future access.
Example 2: Federal employee spouse wants to protect FEHB
Sara is a GS-13 employee. Her husband is a retired Marine using TRICARE. Sara can use TRICARE as a spouse, but she wants to keep FEHB rights for retirement.
Option A: FEHB Self Only
- Premium: about $170 per pay period
- Annual cost: $170 × 26 = $4,420
Option B: No FEHB, use TRICARE only
- Immediate premium savings: roughly $4,420 per year
If Sara is 8 years from retirement, she might decide to use TRICARE now and enroll in FEHB later in time to meet the 5-year rule. But if she is only 4 years from retirement, waiting may be too late.
Example 3: Age 65 changes the picture
Tom is a retired Air Force member and federal retiree. He has FEHB and TRICARE. At 65, he becomes eligible for Medicare. To use TRICARE For Life, he generally must have Medicare Part B.
Part B has a monthly premium. In 2025, the standard Medicare Part B premium is $185.00 per month, or:
- $185 × 12 = $2,220 per year
Now Tom’s choices may include:
- FEHB + Medicare + TRICARE For Life
- Suspend FEHB and use Medicare + TRICARE For Life
- Keep FEHB if he wants its extra coverage or provider access
This is why health coverage planning should not be done in a vacuum. CMS.gov has Medicare rules, and VA.gov can help if you also use VA care.
You can also use the tax calculator to see how premium changes affect your take-home pay.
Common mistakes people make with FEHB and Tricare
Here are the big ones.
- Thinking cheaper now means better later. It might not. The FEHB 5-year rule can change everything.
- Canceling FEHB instead of suspending it in retirement. Suspension may let you come back later.
- Assuming spouses have the same best option. They often do not.
- Ignoring provider networks. A lower premium does not help if your doctors are out of network.
- Forgetting Medicare at 65. TRICARE For Life has its own rules tied to Medicare Part B.
- Using bad info from forums. Online groups can help, but always verify with OPM.gov, TRICARE.mil, and Military OneSource.
It also helps to read trusted coverage from places like FedWeek, GovExec, Federal Times, and Military.com.
Step-by-step: how to choose between FEHB and Tricare
Here’s a simple way to make the decision.
Step 1: List who is eligible for what
Write down each family member and note:
- FEHB eligible?
- TRICARE eligible?
- Medicare eligible?
- VA health care eligible?
Step 2: Check your federal retirement timeline
Ask yourself:
- How many years until I retire from federal service?
- Will I meet the FEHB 5-year rule?
- Do I want the option to carry FEHB into retirement?
If you are close to retirement, this step is huge.
Step 3: Compare annual cost, not just monthly premium
Look at:
- Premiums or enrollment fees
- Deductibles
- Copays
- Prescriptions
- Specialist visits
- Expected surgeries or big care needs
A plan with a lower premium can still cost more overall.
Step 4: Check your doctors and hospitals
Make a short list of:
- Primary care doctor
- Main specialists
- Hospital system
- Pharmacy
Then verify each one under FEHB and TRICARE.
Step 5: Decide whether FEHB is for current use or future protection
Some people keep FEHB because they actively prefer it. Others keep Self Only FEHB mainly to preserve retirement rights.
Both can be reasonable.
Step 6: Run your own numbers
This is where a tool saves time. Try the free FEHB guide calculator to see your personal results. It’s much faster than guessing from message boards, and it helps you compare the real cost of your options.

Bottom line on FEHB and Tricare
If you’re asking about FEHB and Tricare, here’s the simple answer: yes, you can often have both, but that does not mean you should pay for both forever. For many military retirees, TRICARE is cheaper. For many federal workers, FEHB is still worth keeping because of provider choice and the 5-year rule for retirement.
The best choice depends on your retirement date, your spouse’s eligibility, your doctors, and whether you want to protect future FEHB access. Don’t make this call based only on today’s premium.
