Fidelity Says a Retired Couple May Need $371,000 for Healthcare. That Is Before Long-Term Care.

Medicare covers far less than most retirees expect, and the gaps hiding beneath the surface can turn a carefully built retirement plan into an emergency spending crisis faster than almost any other force in personal finance.

A married couple retiring at 65 this year should plan for roughly $371,000 in healthcare costs across retirement, based on Fidelity’s new 2026 estimate of $185,500 per person. That figure already includes Medicare Parts B and D premiums, deductibles, coinsurance, and prescription costs. What it excludes may be even more unsettling: most dental care, over-the-counter drugs, and the single largest exposure many retirees face, custodial long-term care.

If the number surprises you, it should. Medicare was built to pay for acute medical care, hospitalization, and physician services. Routine dental work and years of help with bathing, dressing, or eating largely sit outside the program. That is where the $371,000 estimate ends and the bigger risk begins.

Where the $371,000 Actually Goes

Fidelity’s breakdown is revealing. Parts B and D premiums account for 45% of the estimate, other medical expenses such as deductibles and coinsurance consume 48%, and prescription costs make up the remaining 7%.

Start with what Medicare charges before anyone gets sick. The 2026 Part B standard premium is $202.90 per month, up from $185.00 in 2025. For a couple, that alone runs about $4,870 a year before either has seen a doctor. Layer on Part D and either Medigap or Medicare Advantage coverage, and retirement healthcare becomes a permanent monthly bill.

Fidelity assumes enrollment in Original Medicare and Part D. A Medigap policy should not simply be added to the estimate without adjusting the modeled cost-sharing it replaces. Medigap trades many unpredictable deductibles and coinsurance charges for a predictable premium.

Then come the costs that ambush careful planners.

The Part A hospital deductible in 2026 is $1,736 per benefit period, not per calendar year. A benefit period ends only after someone has gone 60 consecutive days without inpatient hospital or skilled nursing care. That means the deductible can be charged more than once in a year. Stay past day 60 and daily coinsurance begins at $434 through day 90, then rises to $868 for each lifetime reserve day.

Skilled nursing follows the same unforgiving arithmetic. Medicare covers days 1 through 20 in full after a qualifying stay, then charges $217 per day for days 21 through 100. After day 100, the patient pays everything.

The Observation Status Trap

Here is the gap many retirees have never heard of. Under Original Medicare, the skilled nursing benefit generally requires a qualifying three-day inpatient hospital stay. A patient can spend several nights in a hospital bed while officially classified as an outpatient receiving observation services. Those days do not count.

A retiree sent to a skilled nursing facility after five observation days could owe the full cost from day one, often several hundred dollars daily. The bed looks the same. The wristband looks the same. The billing status is what changes the financial outcome.

Ask the hospital each day whether the stay is inpatient or observation. If observation lasts more than 24 hours, the hospital must provide a Medicare Outpatient Observation Notice explaining the status and its consequences. Certain patients whose status is changed from inpatient to observation now also have appeal rights.

Long-Term Care Is the Real Number

The $371,000 estimate stops before custodial long-term care begins. Medicare generally does not pay for extended help with bathing, dressing, eating, or other daily activities when that is the only care needed.

The 2025 national median cost of a private nursing-home room is $129,575 a year, while assisted living runs about $74,400, according to the latest CareScout survey. One extended stay can make the lifetime Medicare estimate look like the smaller number.

Families generally cover this exposure through personal assets, long-term care insurance, or Medicaid after meeting medical and financial eligibility rules. Medicaid limits vary by state, and married applicants receive protections intended to prevent the spouse remaining at home from becoming impoverished. It is more complicated than spending every account down to a universal $2,000 limit.

What Actually Moves the Number

Cost-of-living adjustments  (COLAS) will not close the gap by themselves. The 2026 Social Security COLA is 2.8%, while the standard Part B premium rose nearly 10%. Three moves give a couple more control:

  1. Fund an HSA Aggressively Before Medicare Enrollment. Contributions must end when Medicare begins, but the balance remains available tax-free for qualified expenses. It can pay Medicare premiums, dental and vision bills, and eligible long-term care insurance premiums within age-based limits. It cannot pay Medigap premiums tax-free.
  2. Price Medigap During the Six-Month Open Enrollment Window. In most states, insurers may medically underwrite applications after that one-time federal window closes. Plan G covers most Original Medicare cost-sharing after the Part B deductible, including the Part A deductible and hospital coinsurance. It does not cover routine dental, vision, drugs, or custodial care.
  3. Investigate Long-Term Care Coverage While You Are Still Insurable. Traditional coverage becomes harder to obtain as health conditions accumulate. If the premiums do not fit, compare reduced-benefit policies, hybrid life/LTC coverage, and a deliberate self-funding plan before assuming Medicaid will handle everything.

Medicare remains strong where it reaches. The costly mistake is assuming its arms stretch farther than they do.
