Longevity shift demands holistic retirement planning, MIT AgeLab and Transamerica report
Researchers argue that the conventional focus on leisure-centric retirement is obsolete, urging a framework that integrates well-being, work, and finances across three distinct phases of adulthood.

A joint study by MIT AgeLab and Transamerica, based on surveys of approximately 1,200 individuals and 10 focus groups, indicates that traditional financial planning models are increasingly inadequate. The report argues that conventional approaches, which prioritise leisure-centric retirement, are insufficient given rising American longevity. The research proposes a new framework focusing on well-being, work, and finances across three phases of adulthood.
The data highlights a significant shift in demographic trends. Average US life expectancy grew from 68 years in 1950 to nearly 79 years by 2009. Consequently, the average retirement length for men increased from less than 13 years in 1970 to nearly 19 years in 2020. A 65-year-old in 2023 has a 50% likelihood of living for another two decades, with the number of Americans aged 80 and over projected to nearly triple by 2045.
Midlife adults face complex challenges, including career advancement and caring for both children and parents. The study found this cohort reported the lowest exercise rates and least frequent healthy eating among all age groups surveyed. Researchers suggest that financial advisors should act as coaches to help clients navigate these dynamic stages, prioritising social, emotional, and physical health alongside financial goals.
Traditional financial planning was historically built around comparatively short retirements, focusing primarily on building a nest egg for leisure. However, the report notes that older adulthood is a dynamic phase where clients may celebrate past savings goals while preparing for several more decades of life. This requires a shift from a static view of retirement to one that accommodates changing priorities and life circumstances.
The study was published via SmartAsset’s SmartReads platform. It emphasises that getting financial advice in each phase of adulthood is key to achieving a retirement characterised by overall well-being. This includes having an adequate emergency fund, building net worth, and planning for long-term needs such as Social Security and Medicare.
