The Healthcare Cost Gap: Why Retirees Get It Wrong

Study after study arrives at the same conclusion: Americans consistently and significantly underestimate what healthcare will cost in retirement. This is not simply a knowledge problem — it reflects a systematic set of planning assumptions that do not align with the reality of retirement healthcare costs.

The consequences of underestimating healthcare costs are concrete and serious: retirement income that runs short, forced reductions in other spending categories, depletion of savings that were intended for other purposes, and in some cases, financial hardship in later years when healthcare needs — and costs — are at their peak.

How Large Is the Underestimation?

Research on retirement preparedness consistently finds that retirees estimate healthcare costs at half to two-thirds of what they actually end up spending. A couple who expects to spend $150,000 on healthcare in retirement is more likely to actually spend $300,000 or more — and that is before any long-term care costs are included. When long-term care is added, total lifetime healthcare exposure for a couple can easily exceed $500,000 to $600,000.

The Most Common Mistakes in Healthcare Cost Estimation

Mistake 1: Assuming Medicare Is Nearly Free

Many people enter retirement with the impression that Medicare is essentially free or very low cost because they have paid Medicare taxes throughout their career. In reality, Medicare has meaningful premiums — Part B premiums are paid monthly by all enrollees and increase with income. Part D prescription drug plans carry additional premiums. And most retirees benefit from adding supplemental coverage (Medigap or Medicare Advantage) to manage cost-sharing, adding another layer of premium cost.

Mistake 2: Forgetting Medicare's Gaps

Original Medicare has no out-of-pocket maximum, meaning a serious illness could generate unlimited cost-sharing without supplemental coverage. Dental, vision, and hearing — common and significant expenses for older adults — are largely excluded. Many retirees are surprised to find that a dental procedure, hearing aids, or vision correction represent costs they must pay entirely out of pocket.

Mistake 3: Using General Inflation for Healthcare Projections

Healthcare costs have historically risen at 4% to 6% annually — considerably faster than the 2% to 3% general inflation rate most retirement models use. A 20-year retirement projection that uses general inflation for healthcare will systematically understate costs in the later, more expensive years of retirement. Applying a healthcare-specific inflation rate to medical cost projections produces significantly more realistic estimates.

Mistake 4: Treating Long-Term Care as a Separate Issue

Long-term care is frequently excluded from healthcare cost estimates, treated as a distinct concern to be addressed separately — or not at all. But long-term care is, for the majority of Americans who need it, the single largest healthcare cost of retirement. Approximately 70% of Americans who reach 65 will need some form of long-term care; the average duration is 3 years; the annual cost of a private nursing home room exceeds $95,000 nationally. Excluding this exposure from healthcare cost modeling creates a major planning gap.

Mistake 5: Planning for Average Costs Without Stress-Testing

Average healthcare cost estimates provide a useful baseline, but individual experience can vary significantly from the average. A serious health event, a complex chronic condition, or an extended long-term care need can generate costs far above the average projection. Stress-testing a retirement income plan against above-average healthcare cost scenarios — not just the midpoint estimate — is essential for robust planning.

Building a Realistic Healthcare Cost Estimate

A more accurate approach to retirement healthcare cost estimation includes these components:

• Medicare premiums: Part B (with IRMAA projection based on expected income), Part D, and supplemental coverage
• Out-of-pocket medical costs: Deductibles, copays, coinsurance beyond what supplemental insurance covers
• Dental, vision, hearing: Realistic annual budgets for these excluded categories
• Healthcare inflation adjustment: 4% to 6% compound annual growth on medical costs
• Long-term care: Modeled separately with a dedicated funding strategy covering the realistic range of care scenarios

Correcting the Underestimation: What to Do Now

If your current retirement plan uses optimistic healthcare cost assumptions, there are practical steps to address the gap:

• Revise healthcare cost projections with realistic inflation assumptions and full cost component accounting
• Evaluate whether current guaranteed income streams are sized to cover revised healthcare costs
• Address the long-term care gap with dedicated coverage before health changes make coverage harder or impossible to obtain
• Review Medicare supplemental coverage options to ensure out-of-pocket exposure is appropriately managed
• Maximize HSA contributions before retirement to build a dedicated, tax-advantaged healthcare reserve
