TRICARE for Life Costs: 2026 Out-of-Pocket Limits and Medicare Premiums
Use this guide to understand the assumptions, inputs, results, and next steps behind the calculator.
For military retirees turning 65, navigating the transition from TRICARE Prime or Select to TRICARE for Life (TFL) marks a major shift in healthcare planning. TFL serves as Medicare wrap-around coverage, meaning Medicare pays your provider first, and TFL pays the remaining out-of-pocket costs for covered services. While TFL itself has no enrollment fees, it is not entirely free. To keep TFL active, you must enroll in and pay monthly premiums for Medicare Part B.
Understanding how much healthcare costs in retirement requires projecting your Medicare Part B premiums, potential income-based surcharges, and your TRICARE catastrophic cap. This calculator estimates your total annual and lifetime out-of-pocket healthcare costs as a military retiree. If you are retiring from the military before age 65, you may also want to use the health insurance bridge calculator to map out your costs until TFL eligibility begins.
2026 TRICARE for Life Out-of-Pocket Thresholds
Your out-of-pocket expenses under TRICARE for Life are primarily limited by two factors: the Medicare Part B deductible and the TRICARE catastrophic cap.
Because TFL acts as a secondary payer to Medicare, you will rarely see a medical bill for services covered by both programs. However, for services covered by TRICARE but not Medicare (or if you receive care overseas where Medicare does not apply), you must meet a small annual deductible before TFL begins paying. Once your out-of-pocket costs reach your catastrophic cap, TRICARE covers 100% of the remaining allowable charges for the year.
| Cost Component | Group A (Entered before Jan 1, 2018) | Group B (Entered on/after Jan 1, 2018) |
|---|---|---|
| TFL Annual Deductible | $150 per individual | $150 per individual |
| Catastrophic Cap (2024 Base) | $3,500 per family | $4,206 per family |
| Est. Catastrophic Cap (2026) | ~$3,641 per family | ~$4,375 per family |
| Medicare Part B Premium | Required (Standard ~$185/mo) | Required (Standard ~$185/mo) |
Note: The catastrophic cap increases annually based on inflation. The calculator automatically projects these caps forward to 2026 and beyond based on historical cost increase rates.
Understanding these limits is vital when using a retirement needs calculator to set your baseline budget. For federal employees who also served in the military, you may need to compare these TFL limits against civilian options using the FEHB vs. Medicare calculator.
How Medicare Part B and IRMAA Impact Your TFL Budget
The most significant recurring cost for a TRICARE for Life beneficiary is the Medicare Part B premium. For 2026, the standard Part B premium is projected to be approximately $185 per month. However, if your income exceeds certain thresholds, you will be subject to the Income-Related Monthly Adjustment Amount (IRMAA).
IRMAA is a surcharge added to your standard Part B premium. Medicare calculates this based on your Modified Adjusted Gross Income (MAGI) from your tax return two years prior. For example, your 2026 Part B premiums are determined by your 2024 tax return.
Projected 2026 IRMAA Surcharge Tiers
| Tier | Single Filer MAGI | Married Filing Jointly MAGI | Est. Monthly Add-On |
|---|---|---|---|
| Standard | Up to $106,000 | Up to $212,000 | $0 |
| Tier 2 | $106,001 - $133,000 | $212,001 - $266,000 | +$73.00 |
| Tier 3 | $133,001 - $166,000 | $266,001 - $332,000 | +$183.00 |
| Tier 4 | $166,001 - $199,000 | $332,001 - $398,000 | +$293.00 |
| Tier 5 | $199,001 - $499,999 | $398,001 - $749,999 | +$403.00 |
| Tier 6 | $500,000 and above | $750,000 and above | +$439.00 |
Values are estimates projected from base data. The calculator applies a custom inflation rate to determine your exact tier.
If you are a high-income retiree, IRMAA can easily double or triple your mandatory healthcare costs. Managing your MAGI through careful withdrawal sequencing or Roth IRA tax planning before age 63 is one of the most effective ways to keep your TRICARE for Life costs low. If you are unsure how traditional IRA withdrawals affect your MAGI, the IRA calculator can help project your future taxable distributions.

Group A vs. Group B: Which TRICARE Category Are You In?
Your TRICARE group determines your catastrophic cap, which is the absolute maximum you will pay out-of-pocket for TRICARE-covered services in a single calendar year.
TRICARE Group A includes service members and retirees who entered the military before January 1, 2018. If you fall into this category, your catastrophic cap is lower, providing a tighter safety net against catastrophic medical events.
TRICARE Group B includes service members who entered the military on or after January 1, 2018. This group aligns with the implementation of the Blended Retirement System (BRS). Group B beneficiaries face a higher catastrophic cap that adjusts annually based on the cost-of-living adjustment (COLA).
If you are a Group B member pursuing early financial independence, you can model your aggressive savings strategies using the FIRE calculator to ensure your portfolio can handle the higher out-of-pocket risk. You can also use the how long will my money last calculator to stress-test your portfolio against a year where you hit your maximum catastrophic cap.
The Math Behind Your Projected TFL Expenses
The calculator projects your total healthcare liability by combining your Medicare premiums, potential IRMAA surcharges, and your expected medical expenses, capped by TRICARE rules.
The calculator applies this formula to determine your Medicare Part B premium:
Part B Premium = (Standard Premium + IRMAA Add On) × 12
Where:
- Standard Premium = The base monthly cost for Medicare Part B, adjusted for annual premium inflation.
- IRMAA Add On = The monthly surcharge based on your MAGI and filing status.
To determine your annual out-of-pocket costs for medical services, the calculator uses this logic:
Annual Service Out Of Pocket = min(Expected Medical Expenses, Catastrophic Cap)
Where:
- Expected Medical Expenses = Your projected total cost for medical services before insurance, adjusted for medical inflation.
- Catastrophic Cap = Your maximum financial exposure based on your TRICARE Group (A or B), adjusted for annual TFL cost increases.
Finally, your total annual cost is calculated and adjusted for inflation to show your real purchasing power:
Total Annual Cost = Part B Premium + Annual Service Out Of Pocket
Real Annual Cost = Total Annual Cost / (1 + General Inflation Rate)^Years
Where:
- Total Annual Cost = The nominal dollar amount you will pay in a future year.
- Real Annual Cost = The cost translated back into today's dollars.
- Years = The number of years from the present day to the projection year.
By running these formulas year by year, you can build a more accurate model in your retirement withdrawal calculator and ensure you are pulling enough income to cover healthcare without depleting your principal. If you are setting a long-term target, the retirement goal calculator can help you factor these lifetime costs into your final number.
Strategic Planning for Military Retiree Healthcare Costs
Even with the robust protection of TRICARE for Life, healthcare will remain a permanent line item in your retirement budget. Because TFL covers so much of the actual medical service costs, your planning should focus heavily on controlling your Medicare Part B premiums.
1. Manage Your MAGI to Avoid IRMAA
Because IRMAA is based on your tax return from two years prior, the income you generate at age 63 dictates your Medicare premiums at age 65. If you plan to sell a business, exercise stock options, or take large taxable distributions from a traditional TSP or 401(k), try to do so before age 63. Alternatively, spreading large withdrawals across several years can keep you from spiking into a higher IRMAA tier.
2. Leverage the TRICARE Pharmacy Program
One of the greatest benefits of TRICARE for Life is the TRICARE Pharmacy Program. Medicare beneficiaries typically have to purchase a separate Medicare Part D plan to cover prescription drugs. TFL beneficiaries do not need Part D because the TRICARE pharmacy benefit is creditable coverage and generally offers lower out-of-pocket costs. Avoiding Part D premiums saves the average retiree hundreds of dollars a year.
3. Plan for Non-Covered Services
While TFL and Medicare coordinate to cover nearly all hospital and medical services, they do not cover everything. Routine dental care, routine vision care, hearing aids, and long-term custodial care are generally excluded. You will need to budget for these separately, perhaps by utilizing the Federal Employees Dental and Vision Insurance Program (FEDVIP) if eligible.
If you are worried you haven't saved enough to cover these non-covered services, read is it too late to save for retirement? for catch-up strategies. You can also use the Social Security leveling calculator to smooth your income if you plan to retire before claiming benefits, ensuring you have the cash flow to cover early medical expenses. Testing your strategy with a safe withdrawal rate calculator can provide peace of mind that your portfolio will survive unexpected medical shocks.

Frequently Asked Questions About TRICARE for Life Costs
What is TRICARE for Life and how does it work with Medicare?
TRICARE for Life is Medicare wrap-around coverage for TRICARE-eligible beneficiaries who have Medicare Part A and Part B. When you receive care, your provider bills Medicare first. Medicare pays its portion, and then automatically forwards the claim to TRICARE. TFL then pays the remaining out-of-pocket costs for TRICARE-covered services.
Is there a monthly premium for TRICARE for Life?
No. There are no enrollment fees or monthly premiums specifically for TRICARE for Life. However, you are legally required to enroll in and pay the monthly premiums for Medicare Part B to maintain your TFL eligibility.
Do I need to buy a Medicare Part D prescription drug plan?
In most cases, no. TRICARE for Life includes the TRICARE Pharmacy Program, which provides robust prescription drug coverage. Because this is considered "creditable coverage," you will not face a late enrollment penalty if you decide to buy a Part D plan later, though very few TFL beneficiaries find Part D necessary.
Does the TRICARE catastrophic cap cover my Medicare Part B premiums?
No. The catastrophic cap only applies to your out-of-pocket costs for TRICARE-covered medical services and prescriptions. Your Medicare Part B premiums do not count toward the catastrophic cap, and you must continue paying them even if you reach the cap.
What happens if my spouse is younger than 65?
TRICARE eligibility is individual. If you turn 65 and transition to TRICARE for Life, your younger spouse will remain on their current TRICARE plan (such as TRICARE Prime or Select) until they reach age 65 and become eligible for Medicare.
Does where I live affect my TRICARE for Life coverage?
TFL coverage is available worldwide. However, Medicare generally does not provide coverage outside the United States and its territories. If you receive care overseas, TRICARE becomes the primary payer, and you will be subject to the standard TRICARE annual deductible and cost-shares until you reach your catastrophic cap. If you plan to retire abroad, you may want to review the best states to retire for taxes to optimize your domestic tax residency.
How does life expectancy factor into my lifetime healthcare costs?
Because Medicare premiums are paid monthly for the rest of your life, a longer retirement means higher total lifetime costs. You can use the Social Security life expectancy calculator to estimate your planning horizon and multiply your projected annual TFL costs by those years to find your total liability.
Next Steps for Your Retirement Plan
Understanding your TRICARE for Life costs is just one piece of the military retirement puzzle. Because your healthcare costs are largely capped, you have a distinct advantage when planning your income strategy compared to civilian retirees.
To see how your military pension, Social Security, and investment withdrawals combine to cover these costs, use the retirement paycheck calculator. If you are still years away from separation and want to ensure your TSP and outside investments are on track, the retirement number calculator can help you set a definitive target for your golden years.
