The Number Most Retirement Plans Get Wrong
When most people model their retirement, they think in terms of housing, food, travel, and maybe some leisure spending. Healthcare shows up as a vague line item — a few hundred dollars a month tacked on as an afterthought. This is a structurally dangerous mistake.
Fidelity Investments' annual retirement healthcare cost study puts the average out-of-pocket healthcare cost for a retired couple at $315,000 — and that number excludes long-term care entirely. It's after Medicare. It's just the cost of being alive and managing health in retirement: premiums, copays, dental, vision, hearing aids, prescriptions, and procedures Medicare doesn't fully cover.
That's $315,000 that needs to come from your portfolio — on top of your living expenses. If you're planning for $60,000 a year in retirement spending and haven't carved out a separate healthcare reserve, your plan has a six-figure blind spot.
At 5.4% annual healthcare inflation, today's $12,600 per couple annual cost becomes approximately $21,700 in 10 years and $37,400 in 20 years. The Retirement Calculator lets you model this as a separate, faster-inflating cost bucket.
Model your real retirement number →Why Healthcare Inflation Is a Different Problem
General CPI inflation runs around 3.8% in 2026. Healthcare inflation has historically run at 5.4% — nearly 1.5 percentage points higher. That differential compounds badly over a 20- or 30-year retirement horizon.
If you're using a general inflation assumption in your retirement calculator, your healthcare costs are being systematically underestimated. You're projecting them at 3.8% when they'll grow at 5.4%. Over 20 years, that gap produces a six-figure shortfall in purchasing power — just for healthcare.
The Inflation Calculator lets you run this scenario directly: enter your current annual healthcare estimate, set inflation to 5.4%, and project 10 or 20 years out. Then re-run at 3.8% and see the gap. That gap is the amount your retirement plan is currently ignoring.

The Pharmaceutical Tariff Wildcard
Layered on top of the structural inflation problem is a 2026-specific risk: pharmaceutical tariffs. The Trump administration has signalled tariffs of up to 200% on imported pharmaceuticals, with implementation targeted for mid-2026. The US imports significant volumes of pharmaceutical ingredients and finished drugs from India, China, Ireland, and Germany.
The direct consumer impact is uncertain — drug manufacturers may absorb some costs, and Medicare's new drug negotiation provisions may buffer others. But for retirees on multiple prescription medications, even a 10–15% increase in drug costs adds hundreds to thousands of dollars per year to an already substantial healthcare bill.
This is not a reason to panic. It is a reason to build conservatism into your healthcare line item — to assume the high end of the range, not the low end, and to stress-test your plan against a scenario where prescription costs rise meaningfully faster than historical healthcare inflation.
The Retirement Calculator lets you set a dedicated "other expenses" category for healthcare and apply a different inflation rate than your general cost-of-living assumption. Model $12,600/year at 5.4% healthcare inflation versus your general 3.8% CPI assumption — and see the dollar gap in your plan.
Add healthcare to your plan →The Bridge Period Problem: Ages 62 to 65
Healthcare cost risk is highest in the bridge period between early retirement and Medicare eligibility at 65. If you retire at 62, you face three years of paying for full private insurance coverage — without employer subsidies, without Medicare.
ACA marketplace premiums for a 62-year-old couple can easily reach $2,000–$3,000 per month depending on location and plan tier, before any subsidies. Subsidies are income-based and phase out above 400% of the federal poverty level. A couple with $80,000 in retirement income may receive minimal subsidy and face $20,000–$30,000 in annual pre-Medicare health insurance premiums.
This bridge period cost can fundamentally change the viability of early retirement at 62 versus 65. It's a line item that needs to be explicitly modelled — not assumed away.
Long-Term Care: The Number Behind the Number
The $315,000 figure from Fidelity deliberately excludes long-term care — nursing home stays, assisted living, in-home care. This is not an oversight; it's an acknowledgment that long-term care costs are so variable and so person-specific that a single aggregate number would be misleading.
But the aggregate data is still alarming: the median annual cost of a private room in a nursing facility is approximately $108,000 in 2026. The average length of a nursing home stay is 2.5 years. That's $270,000 — in addition to the $315,000 in ordinary healthcare costs.
Not everyone will need nursing home care. But the probability of needing some form of paid long-term care at some point after 65 is approximately 70%. Most retirement plans model this risk as zero. That's a structural blind spot in American retirement planning.
The HSA Is Your Best Tool — Before Medicare
If you're still working and enrolled in a high-deductible health plan (HDHP), the Health Savings Account (HSA) is the most efficient vehicle for pre-funding retirement healthcare costs. Contributions are pre-tax. Growth is tax-free. Withdrawals for qualified medical expenses are tax-free. After 65, withdrawals for any purpose are taxed at ordinary income rates — making the HSA functionally equivalent to a traditional IRA as a fallback.
The 2026 HSA contribution limits are $4,400 for self-only coverage and $8,750 for family coverage (plus a $1,000 catch-up contribution for those 55 and older). Maxing your HSA for 10 years and investing it at 7% returns produces approximately $62,000 (self-only) to $124,000 (family) — a meaningful contribution toward the $315,000 healthcare reserve.
See the full HSA strategy article for the complete model and 2026 limit details.
Use the Compound Interest Calculator to model a dedicated healthcare savings bucket. Enter $300/month at 7% for 20 years. That builds a $185,000 reserve specifically earmarked for healthcare — a substantial portion of the Fidelity $315,000 target.
Build your healthcare reserve →How to Build Healthcare Into Your Retirement Plan
The practical steps are straightforward, even if executing them requires discipline:
1. Isolate the line item. Don't bundle healthcare into a general living expense assumption. Give it its own row in your retirement budget, with its own inflation rate (5.4%, not 3.8%).
2. Model the bridge period separately. If you plan to retire before 65, project pre-Medicare insurance costs explicitly. Don't assume you'll figure it out later.
3. Build a dedicated reserve. Whether through an HSA, a taxable account specifically earmarked for healthcare, or a conservative bond allocation, treat healthcare as a separate bucket with a separate drawdown strategy.
4. Stress-test pharmaceutical costs. Run a scenario where your prescription drug costs rise 15–20% in the next two years due to tariff pass-through. Does your plan still work? If not, you need more margin.
5. Address long-term care separately. Long-term care insurance, hybrid life/LTC policies, or a larger portfolio buffer — but don't leave it as an implicit zero in your plan.
