The 90+ Rule of Retirement emphasizes planning for a retirement that could extend into your 90s or beyond. With Americans living longer than ever, traditional retirement planning may fall short. This guide explores strategies for financial security, healthcare planning, lifestyle choices, and real-life examples to ensure a fulfilling and sustainable retirement.


Why the 90+ Rule Matters

Retirement is no longer a brief period of rest following decades of work. Advancements in healthcare, better living conditions, and improved medical interventions mean that many Americans are living well into their 90s. While this is great news, it also presents unique challenges. Financial plans that once seemed sufficient may now fall short if we fail to account for longer lifespans, rising healthcare costs, and lifestyle changes.

The 90+ Rule of Retirement encourages individuals to plan as if they will live to age 90 or beyond, taking into account finances, health, and overall life satisfaction. By adopting this approach, you can prevent running out of money and ensure a retirement filled with purpose, comfort, and independence.


The Case for the 90+ Rule

1. Increased Life Expectancy

According to the Centers for Disease Control and Prevention (CDC), average life expectancy in the U.S. has steadily increased over the past decades. As of 2025, many Americans who reach 65 are likely to live well into their 80s or 90s. This longevity makes traditional retirement plans—often based on a 20–25 year horizon—potentially insufficient.

Example:
Consider John, a 65-year-old retiree in 2025. If he only plans for 20 years, he may run out of funds by age 85, leaving his last years of life financially constrained. By planning for 90+, John ensures that he can maintain his lifestyle even if he lives longer than expected.

2. Rising Healthcare Costs

Healthcare expenses tend to increase with age, and many retirees underestimate these costs. The Fidelity Retiree Health Care Cost Estimate suggests that a 65-year-old couple retiring today could need approximately $300,000 to cover healthcare throughout retirement. This includes premiums, out-of-pocket costs, prescriptions, and long-term care.

Tip: Start saving early for healthcare and consider options such as long-term care insurance to mitigate financial strain.

3. The Uncertainty of Social Security

Social Security benefits provide a foundational income stream, but the system is changing. Delaying benefits can increase monthly payouts, but it also means you need other financial resources to bridge the gap. Planning around a longer lifespan ensures you can leverage Social Security without risk of running out of funds.


Core Strategies for the 90+ Rule

1. Financial Planning for Longevity

Financial planning is the cornerstone of the 90+ Rule. Without a solid plan, retirees risk exhausting their resources decades before the end of life.

Key Steps:

  • Estimate Retirement Expenses Thoroughly:
    Include daily living costs, travel, hobbies, healthcare, and long-term care. Use retirement calculators to model various scenarios.
  • Diversify Income Sources:
    Avoid relying solely on Social Security. Include pensions, investments, annuities, and part-time work. A mix of guaranteed income and flexible investment portfolios can reduce financial stress.
  • Adjust Withdrawal Strategies:
    Traditional guidelines, like the 4% rule, may not be sufficient for a retirement exceeding 30 years. Consider a lower withdrawal rate or a dynamic strategy that adjusts with market conditions.

Example:
The Johnsons, a couple in their 60s, retired early and traveled extensively. Without planning for 30+ years of retirement, they had to downsize and take part-time work to sustain their lifestyle. Their experience highlights the importance of conservative financial assumptions and flexible plans.


2. Healthcare Planning

As we age, medical expenses increase significantly. Proper planning ensures that healthcare does not erode your retirement funds.

Recommendations:

  • Long-Term Care Insurance:
    Consider policies that cover nursing homes, assisted living, or in-home care.
  • Understand Medicare:
    Medicare Parts A, B, C, and D cover different needs. Research options like Medicare Advantage and supplemental insurance to fill coverage gaps.
  • Adopt a Healthy Lifestyle:
    Preventive care—exercise, balanced nutrition, and regular check-ups—reduces medical costs and improves quality of life.

Example:
Margaret, a 72-year-old widow, lives independently thanks to long-term care insurance and healthy habits. She volunteers and maintains social connections, demonstrating how proactive planning promotes both financial and emotional well-being.


3. Lifestyle Considerations

Money isn’t everything. Retirement longevity demands attention to purpose, social interaction, and living conditions.

Strategies:

  • Stay Socially Connected:
    Engage in clubs, volunteering, or community activities to combat isolation and depression.
  • Pursue Hobbies and Interests:
    Travel, creative pursuits, or learning new skills contribute to a meaningful retirement.
  • Housing Planning:
    Evaluate whether your current home meets future needs. Consider downsizing, retrofitting for accessibility, or exploring senior living communities.

2. How Do I Estimate My Retirement Expenses?

Include housing, utilities, healthcare, transportation, lifestyle, travel, hobbies, and long-term care. Use calculators and conservative assumptions to create realistic projections.
