Retirement planning conversations tend to focus on investment returns, withdrawal rates, and Social Security timing. These are all important. But there is one number that consistently blindsides retirees — one that dwarfs most other budget line items and grows faster than almost any other expense in retirement.
That number is the cost of healthcare. And in 2026, the data has never been clearer about just how significant it is.
The Numbers That Should Be in Every Retirement Plan
According to the 2026 Milliman Retiree Health Cost Index — published just weeks before this article — a healthy 65-year-old couple retiring in 2026 will need to have saved approximately 18,000 just to cover healthcare costs over the course of their retirement under Original Medicare with Medigap Plan G plus Part D coverage. That figure is up 0,000 from 2025 — a 7.7% increase in a single year.
Over their remaining lifetime, that same couple is projected to spend an average of 37,000 on healthcare expenses.
Let that figure land properly. 37,000. On healthcare alone. Not housing. Not food. Not travel. Healthcare.
And that is the average for a healthy couple. For couples with significant health conditions, or who need long-term care, the figure climbs considerably higher. Some couples with costly prescription drug requirements may need up to 69,000 in savings for healthcare under certain Medicare configurations, according to EBRI research.
Why Healthcare Costs Are Accelerating Faster Than Most Budgets Assume
The 2026 HealthView Services Retirement Healthcare Costs Data Report identifies a troubling structural trend: healthcare cost inflation is running at a projected long-term rate of 5.8% annually, while Social Security cost-of-living adjustments are projected to rise at only 2.4%. The gap compounds relentlessly.
The practical consequence of this gap is stark: a healthy 55-year-old couple with average Social Security benefits will need 104% of their projected Social Security income just to cover medical premiums and out-of-pocket expenses. Their healthcare costs will effectively consume their entire Social Security benefit — and then some.
Medicare Part B premium alone rose from 85 in 2025 to 02.90 per month in 2026 — a nearly 10% increase in one year. The Part A hospital deductible increased to ,736 per benefit period. These are baseline costs before supplemental coverage, dental, vision, hearing, and out-of-pocket expenses are added.
For a healthy 65-year-old couple, total annual healthcare costs for standard Medicare programmes are projected to rise from 7,003 in the first year of retirement to 5,513 at age 85, according to HealthView actuarial data. Annual healthcare costs more than triple over the course of a typical retirement.
The Expense Most People Forget Entirely: Long-Term Care
Even the sobering figures above do not include long-term care — and this is where retirement healthcare costs can become genuinely catastrophic for unprepared families.
The baseline statistics on long-term care are unambiguous:
- Approximately 70% of people who reach age 65 will need some form of paid long-term care before they die
- The average duration of care for those who need it is 3 years
- 20% of people who need long-term care require it for more than 5 years
- A 3-year care scenario in assisted living costs between 62,000 and 52,000 at current rates
When long-term care costs are added to standard healthcare costs, a couple’s total lifetime healthcare exposure can easily exceed 00,000 to million in a higher-need scenario.
This is not a figure designed to alarm. It is a figure designed to inform. The retirees who are financially prepared for this are the ones who understood the number well in advance and made decisions in their 40s and 50s accordingly.
The Investment Most People Overlook: Your Own Health
Here is the part of the healthcare-in-retirement conversation that is almost never discussed: your physical health is one of the most powerful financial instruments available to you.
The research on this point is consistent and striking. People who reach retirement in good metabolic health, with low inflammatory markers, healthy cardiovascular fitness, and good cognitive function have dramatically lower healthcare expenditures in retirement than their peers who arrive in poor health. The gap is not marginal — it is often measured in tens or even hundreds of thousands of dollars over the course of retirement.
Every chronic condition you avoid through preventive lifestyle investment is a potentially six-figure saving on your retirement healthcare budget. Every year of additional healthy function is a year your care needs are minimal rather than intensive. The return on investment from prioritising your health in your 40s and 50s is, in purely financial terms, extraordinary.
What Staying Healthier Longer Actually Saves You
To make this concrete, consider two hypothetical retirement scenarios for a 65-year-old couple:
Scenario A — Average Health Retirement
A couple retiring with average health, typical lifestyle habits, and moderate chronic disease risk follows the standard Milliman projection: 18,000 in required healthcare savings, 37,000 in projected lifetime healthcare spend.
Scenario B — Above-Average Health Retirement
A couple retiring in the top quartile of health for their age — non-smokers, regular exercisers, healthy diet, well-managed weight and blood pressure — consistently demonstrates 20 to 30% lower healthcare expenditure in published research, alongside meaningfully lower long-term care needs. On the Milliman figures, this could represent a saving of 0,000 to 90,000 in healthcare costs over retirement.
The gap between Scenario A and Scenario B is not determined at age 65. It is determined by the lifestyle choices made in the decades before retirement.
Where to Start: Know Your Longevity Profile
The first step in planning for retirement healthcare costs accurately is understanding your personal health and longevity trajectory — not the population average, but your own picture based on your lifestyle, habits, and current health behaviours.
Our free longevity quiz at Turn Back Clock is designed to give you exactly that in two minutes. It asks the eight lifestyle questions with the strongest evidence for predicting both health and longevity outcomes, and gives you a personalised assessment of where you stand and where the biggest opportunities to improve are.

Understanding your longevity profile is not just about living longer. It is about living in a way that minimises your future healthcare costs, maximises your retirement quality, and ensures that the savings you have spent decades building are not consumed by preventable medical expenses.
Practical Steps to Reduce Your Retirement Healthcare Exposure
- Start an HSA now if you are eligible: Health Savings Accounts offer a rare triple tax benefit. In 2026, contribution limits are ,400 for individuals and ,750 for families. Money carries over indefinitely and can be invested for growth
- Prioritise preventive health investment in your 40s and 50s: Exercise, diet quality, sleep, and stress management are the highest-leverage interventions for reducing long-term healthcare costs
- Budget healthcare as a hard number in retirement planning: Use 18,000 as your baseline couple’s healthcare savings target and adjust based on your personal health profile
- Research long-term care insurance in your 50s: Premiums are significantly lower when purchased before significant health changes occur
- Understand Medicare options thoroughly before age 65: The choice between Original Medicare with Medigap and Medicare Advantage has lifetime cost implications that vary substantially based on health status and care needs
Key Takeaways
- A healthy 65-year-old couple retiring in 2026 needs approximately 18,000 in savings for healthcare costs alone, according to the 2026 Milliman Retiree Health Cost Index — up 0,000 from 2025
- That couple is projected to spend 37,000 on healthcare over their remaining lifetime under standard Medicare with Medigap coverage
- Healthcare cost inflation is running at 5.8% annually — more than double the projected Social Security COLA of 2.4%
- 70% of people reaching 65 will need paid long-term care, adding a potential 60,000 to 50,000+ to lifetime healthcare costs
- The lifestyle choices you make in your 40s and 50s are among the most powerful financial decisions you will make for retirement
- Retiring in good health can save 0,000 to 90,000 or more in lifetime healthcare expenditure compared to retiring in average health
