Managing uncertainty is one of the most difficult aspects of crafting a retirement strategy. Markets fluctuate, tax laws change, healthcare costs rise unexpectedly, and, perhaps most challenging of all, no one knows how long they will live. However, we believe figuring out longevity—the number of years a person can live in retirement—is one of the most important parts of any financial strategy.
This question becomes even more pressing as people near retirement age. Underestimating life expectancy can lead to running out of money prematurely, whereas overestimating it can result in unnecessary sacrifices during working years. Finding a reasonable, personalized estimate is critical, and longevity calculators can help greatly.
Compass Financial Associates, based in Grand Blanc, Michigan, considers longevity planning one of several components of a personalized retirement strategy. Rather than relying solely on generic averages, we assist clients in determining how long their savings will need to last and how to plan accordingly.
Why Longevity Is So Hard to Predict
Many Americans continue to rely on broad life expectancy averages when planning for retirement. For example, federal statistics may show that someone approaching retirement age today can expect to live into their mid- to late 80s. While these statistics are useful for analyzing population trends, they are insufficient for individual retirees and pre-retirees.
People aren’t average. People’s longevity is influenced by their health, lifestyle, income, education, family history, and access to medical care. Two people of the same age can have dramatically different longevity outcomes.
This uncertainty has grown as retirement income has shifted from traditional pensions to defined-contribution plans like 401(k)s and IRAs. In contrast to pensions, which typically provide lifetime income, these accounts require individuals to save for the long term. Without a clear understanding of longevity risk, retirees may withdraw excessively early or live more sparingly than necessary out of fear.
The Role of Longevity Calculators
Longevity calculators seek to bridge the gap between population averages and individual realities. These tools combine actuarial data with personal information to predict a person’s life expectancy or likelihood of reaching certain ages.
Most calculators require your age and gender, but some go even further. Some common questions are about smoking history, self-rated health, exercise habits, sleep patterns, diet, education level, and income. Some tools take into account previously diagnosed medical conditions or basic clinical measurements like blood pressure.
According to research, self-assessed health is one of the most accurate predictors of longevity. People who rate their health as excellent or very good live far longer than those who rate it as poor. Quitting smoking, maintaining a healthy weight, and engaging in physical activity are all associated with a longer life expectancy.
However, no calculator can offer certainty. These tools are more useful as guides than guarantees. They offer perspective, assisting individuals in avoiding the common tendency to underestimate how long retirement may last—particularly among people in their 50s and 60s, making critical decisions.
Common Mistakes Around Longevity
One common misconception is that one’s personal lifespan will be comparable to that of their parents or grandparents. While family history is important, it does not fully account for medical advances, improved treatments, and changes in living standards, all of which have gradually increased life expectancy over time.
Another issue is oversimplistic assumptions in financial projections. Some retirement projections assume that everyone will live until a certain age, such as 90 or 95. While this method is simple to model, it excludes a wide range of possible outcomes. Some people may find it dangerously optimistic to plan only until the age of 90, while others with serious health issues may find it overly conservative.
Longevity assumptions also influence Social Security claim decisions. Claiming benefits early results in permanently lower monthly payments, whereas delaying benefits increases lifetime income for those who live longer. Retirees who do not conduct a thorough longevity analysis may miss out on significant guaranteed income.
Balancing Optimism and Realism
There is also a risk on the opposite end of the spectrum. Some longevity calculators may overestimate life expectancy for people with multiple positive health factors by adding years for each healthy habit. In reality, when individual behaviors are considered together, their impact is often less significant.
This is why, in our opinion, using calculators in conjunction with professional guidance is the best way to plan for the future. A financial advisor can help interpret results, stress-test options under different scenarios, and ensure that assumptions are neither overly pessimistic nor unrealistically optimistic.
What Longevity Means for Your Retirement Strategy
Planning for a longer life often necessitates major changes to one’s retirement strategy. These could include increasing savings during peak earning years, working for a few extra years, or adjusting investment allocations to support long-term growth.
Longevity assumptions affect withdrawal strategies. A portfolio designed to last 20 years looks very different from one designed to last 30 or 35. As the length of potential retirement increases, healthcare planning, long-term care considerations, and inflation protection become more critical. Perhaps most importantly, longevity planning allows retirees to make more informed and confident decisions.
Why Professional Guidance Matters
While online calculators are useful, they cannot replace a comprehensive financial strategy that is tailored to your specific requirements. Longevity is associated with taxes, investment risk, Social Security, medical expenses, and estate planning. Changes in one area have a wide-ranging impact. Compass Financial Associates can help you incorporate longevity analysis into your retirement strategy. We also work closely with clients to understand their retirement needs, goals, and concerns.
Take the Next Step Toward Confidence
While it’s impossible to predict the future, doing your best to prepare can greatly increase your chances. Understanding how long your savings will last is one of the most important steps you can take to ensure your financial security in retirement.
