Many people estimate their lifespan based on their parents’ experiences, often overlooking generational gains in longevity. As a result, Americans frequently underestimate how long they’ll live and may save less than they need to.
Even modest increases in lifespan can significantly affect outcomes. For example, extending a retirement horizon from 30 to 35 years can increase the risk of depleting savings by 41%, according to research from the Nationwide Retirement Institute and the American College of Financial Services. When you consider inflation and lower returns, that risk can rise substantially.
Addressing longevity risk requires aligning income strategy, withdrawal discipline, and asset allocation. Sustainable withdrawals, diversified income sources, and tools designed for lifetime income — such as annuities and Social Security optimization — help convert savings into durable income.
Here’s how these income strategies function in practice:
- Social Security timing: Delaying benefits increases monthly income and total lifetime payouts, particularly for those who live into their 80s and beyond. This approach may require a plan to bridge income between retirement and age 70, when Social Security reaches its full benefits.
- Annuities: These products provide guaranteed lifetime income, transferring longevity risk to an insurer. They typically involve up-front costs, reduced liquidity, and contractual constraints. These factors make them most appropriate when income certainty is prioritized over flexibility.
- Layered income approach: Relying on multiple income sources reduces dependence on portfolio performance alone. These sources may include Social Security, pensions (if available), retirement account withdrawals, and taxable investments.
- Retirement account strategy: Coordinating withdrawals across pensions, IRAs, and 401(k)s can help maximize income while managing tax exposure and maintaining portfolio longevity.
- Portfolio diversification: Structuring assets by time horizon supports both near-term income needs and long-term growth, reducing the risk of premature depletion.
- Tax-efficient withdrawals: Sequencing withdrawals — such as drawing from Roth accounts in lower-income years and traditional accounts in higher-income years — can extend the life of your savings and improve after-tax outcomes.
While longevity risk cannot be eliminated, it can be managed through deliberate planning and disciplined execution. Because retirement strategies vary widely, working with financial and estate professionals can help tailor an approach to your specific needs.
