What If You Live to 100? Planning for Longevity Risk in Retirement

Explore key ways to address longevity risk in retirement, from income planning to tax efficiency and healthcare considerations.

We’re living longer than ever, and that’s great news. Advances in medicine, better nutrition, and healthier lifestyles have made it possible for many Americans to enjoy full lives well into their 90s—and even reach 100. However, this longer lifespan also introduces one of the most underestimated threats to retirement: longevity risk. 

At Paraclete Wealth Partners, we help clients prepare for retirement realities, not outdated rules of thumb. Planning for longevity risk in retirement requires a thoughtful approach that blends tax-free income strategies, risk-adjusted investment planning, and healthcare protections. It’s not just about making your money last—it’s about making it work wisely for the decades ahead. 

Understanding Longevity Risk 

Longevity risk is the possibility that you’ll outlive your retirement savings. While it may seem like a distant concern, the consequences of not preparing for it can be significant. 

According to the Society of Actuaries, a healthy 65-year-old couple has a nearly 50% chance that at least one partner will live past age 90, and a 20% chance one will live to 95. That means your retirement plan may need to cover 30–35 years of living expenses, medical care, inflation, and taxes

The longer you live, the more likely you’ll face: 

  • Increased healthcare expenses 
  • Higher cumulative tax exposure 
  • Greater vulnerability to market volatility 
  • Inflation eroding purchasing power 
  • The need for long-term care services 

Why Traditional Strategies May Fall Short 

Old-school retirement strategies often assume a 20-year horizon after retirement. They emphasize 4% withdrawal rates, tax-deferred savings, and portfolio longevity based on past market performance. But what happens if those assumptions are wrong? 

If you retire at 65 and live to 100, a 4% withdrawal strategy may leave you underfunded in your 80s or 90s—especially if market returns fluctuate or tax rates rise. And relying heavily on tax-deferred accounts like 401(k)s or IRAs can lead to larger Required Minimum Distributions (RMDs) that push you into higher tax brackets over time. 

David McKnight, author of The Power of Zero, emphasizes that a truly modern retirement plan must anticipate these risks—and counter them with strategic action. 

Proactive Strategies to Mitigate Longevity Risk 

To better prepare for a long retirement, we recommend the following approach: 

  1. Create Tax-Free Income Streams

One of the smartest ways to insulate yourself from tax hikes over a long retirement is to shift assets to tax-free vehicles like Roth IRAs or Life Insurance Retirement Plans (LIRPs). As McKnight points out, if you can position yourself in the 0% tax bracket, future tax increases become irrelevant—because 2x zero is still zero. 

  1. Start Roth Conversions Early

If you wait too long, large RMDs can trigger excessive taxes in your 70s and beyond. Starting Roth conversions strategically in your 50s or early 60s can help spread the tax impact and reduce lifetime tax liability. 

  1. Build a Layered Income Plan

Consider structuring your income with multiple sources that kick in at different phases. For example: 

  • Guaranteed income from annuities or pensions 
  • Tax-free income from Roth accounts or LIRPs 
  • Flexible investments for discretionary spending 

This layered approach offers flexibility, stability, and tax efficiency as your retirement needs evolve. 

  1. Plan for Healthcare and Long-Term Care

A longer life often means rising healthcare costs. Consider long-term care coverage as part of your overall strategy. Hybrid policies, which combine life insurance with long-term care benefits, can be a smart addition to protect assets. 

Don’t Just Plan for Retirement—Plan for Longevity 

Longevity risk in retirement is real, and the impact can be profound if it’s not addressed early. The good news? You don’t have to navigate it alone. At Paraclete Wealth Partners, we take an educational, strategy-first approach inspired by David McKnight’s Power of Zero philosophy. We help clients: 

  • Plan for income that lasts through age 100 and beyond 
  • Protect themselves from rising taxes and health expenses
