Key Finding: 26% Correct, 74% Misunderstand Medicare
A 2025 study by the TIAA Institute shows that just 26% of U.S. adults accurately grasp how Medicare handles retiree healthcare costs. The data reveal a broad misalignment between expectations and what the program actually covers, at a time when healthcare expenses are a central retirement consideration.
The study lead economist said in a briefing that a wide gap in understanding is a real retirement risk for households planning ahead.
Understanding Medicare's True Coverage
- Only 26% answered correctly when asked how much of a typical retiree’s healthcare costs Medicare covers.
- 74% either overestimate Medicare’s reach or admit they do not know the coverage details.
- Medicare covers roughly two-thirds of retiree health expenses, leaving the rest to out-of-pocket costs such as premiums, copays, deductibles, prescriptions, dental, vision, hearing, and long-term care.
Costs Are Rising; Savings Aren’t Keeping Pace
Industry data underscore the financial pressure on retirees. Fidelity projects that a 65-year-old today could face about $172,500 in healthcare costs during retirement, excluding long-term care. With services inflation running above 3% annually and consumer savings rates hovering near 4%, many households face tighter cash flow as health bills rise.
- Fidelity estimate: approximately $172,500 in retirement healthcare costs per person (not including long-term care).
- Healthcare services inflation remains above 3% annually.
- Personal savings rate sits around 4% in recent data.
Impact on Investors and Retirees
The findings have clear implications for retirement planning and investment strategy. If most americans think medicare covers more than it does, households may underfund future health care costs, risking cash-flow stress during the early retirement years or during periods when Medicare outlays don’t cover rising bills.
In markets and portfolios, the perception gap matters. In markets and households, most americans think medicare will shield them from the bulk of health costs, but the data show otherwise. That mismatch can lead to aggressive withdrawal assumptions that fail when health expenses spike.
What Plan Ahead
- Build a dedicated healthcare budget for retirement, clearly separated from other living costs.
- Review Medicare options—Part B, Part D, and supplemental plans—and compare Medigap versus Advantage routes to balance out-of-pocket exposure.
- Consider long-term care planning now, including options such as private policies, hybrid policies, or self-insurance strategies.
- Leverage tax-advantaged savings for health costs, including an HSA if eligible, to hedge future medical bills.
- Work with a fiduciary financial advisor to model retirement cash flows under various health-cost scenarios.
Market and Policy Context
Healthcare costs continue to loom large for retirees, with service-based inflation outpacing general price growth. The 2025 study arrives as policy debates around Medicare funding and long-term sustainability intensify, potentially affecting benefit design and out-of-pocket costs over the next decade. For investors, this means added emphasis on reliable income streams and flexible withdrawal plans that can adapt to higher-than-expected health spending.
Takeaway for 2025 and Beyond
The numbers deliver a blunt reminder: retirement planning cannot assume Medicare will cover the majority of health bills. For investors and households alike, the path to a durable retirement requires explicit budgeting for health care, contingency funding for long-term costs, and a plan that accommodates health-cost shocks. The phrase most americans think medicare appears frequently in headlines, yet the practical reality is more nuanced; planners should bake that uncertainty into every projection and approach retirement with greater flexibility.
