Understanding how long you may live in retirement

Living to 100 may sound far off, but it’s becoming more possible every day. Thanks to advances in healthcare, technology and access to better resources, life expectancy continues to rise. In fact, since Social Security began, life expectancy in the United States has increased by 17 years and continues to rise.1

Living longer can offer more time to enjoy retirement—but it also means you may need to adjust your planning to ensure long-term financial security. If you’re nearing retirement, now is a smart time to revisit your goals and check your financial readiness for the years ahead.

A recent study conducted by the TIAA Institute and the Global Financial Literacy Excellence Center (GFLEC) reveals that only 32% of adults know how long people tend to live upon reaching retirement age.2 This can lead to underestimating lifespan and misjudging how much retirement savings they need.

Longevity literacy among u.s. adults

On average in the U.S., how long will a 65-year-old man or woman live?

The 2024 P-Fin Index survey included three multiple-choice questions indicative of longevity literacy, each related to the distribution of life expectancy among 65-year-olds in the U.S.

Understanding longevity can better prepare you to make thoughtful decisions not only about your finances, but about your health and lifestyle too.

Three factors affecting your longevity planning

Knowing how long you might live in retirement is only one part of the equation. Equally important is the quality of those years. A fulfilling retirement often depends on social connection, physical and mental wellness, as well as financial confidence.

  • Happiness

  • Studies suggest that strong social connection may contribute to longer life. People with close relationships tend to experience lower rates of anxiety and depression, stronger immune systems, and greater self-esteem.3

    Even small actions—checking in on a friend, calling a loved one, or volunteering—can help foster a greater sense of connection and belonging.

  • Health

  • It’s probably no surprise that eating well and staying physically active are important for longevity, but so is keeping your brain engaged. Mental stimulation plays a big role in long-term wellness. This can include activities like learning a new skill, doing crossword puzzles, or practicing mindfulness to keep your mind sharp and energized.

  • Financial Readiness

  • As we age, financial planning becomes even more important. Today’s retirees often spend twice as long in retirement as previous generations. Understanding how long you may live—and planning accordingly—can help you stay ahead of expenses and avoid financial surprises. Don’t overlook major expenses, like retirement healthcare costs and housing, which can significantly impact your budget.

    Being financially prepared is essential at any age. The average retiree today can expect to spend about 20 years in retirement, but many are living well beyond that.4

    That’s why understanding your potential lifespan and how to support it is crucial—especially early in your career when you may be laying the foundation for future financial security. The earlier you begin retirement planning and saving, the better positioned you’ll be to manage long-term costs and maintain your quality of life.

Prepare for the future

You can’t predict how long you will live, but you can prepare for it. A financial tool, like an annuity, which offers guaranteed retirement income, could be a way to replace your salary in retirement for as long as you live. If you’re considering this option or just want to learn more, a financial professional at TIAA can help.
