The Retirement Blind Spot: Why Longevity Literacy Matters for South Africans

The Retirement Blind Spot: Why Longevity Literacy Matters for South Africans 

For many South Africans approaching or even well into their working years, retirement planning often centres on familiar themes: pension contributions, investment returns, and lifestyle goals. Yet, one critical factor is routinely overlooked — longevity literacy. Without a clear understanding of how long one might live, even the most well-structured retirement plan can unravel prematurely. 

Longevity literacy refers to a person’s ability to realistically estimate how long they are likely to live. It’s not about wishful thinking, but about incorporating data, genetics, lifestyle, and social trends to plan for an increasingly longer post-retirement life. In a 2022 global study by the TIAA Institute and the Global Financial Literacy Excellence Center, only 12% of respondents could accurately estimate life expectancy at age 60 — a figure that underscores the severity of this blind spot (Yakoboski et al., 2022). 

In South Africa, this issue is especially pertinent. According to the World Health Organization, life expectancy at birth has risen steadily, and for those reaching 60, the average woman can expect to live another 21 years and the average man another 17 years — figures that may extend further with access to improved healthcare and healthier lifestyles. Yet, retirement planning models used by many South Africans are often based on outdated assumptions, with many planning for only 15 to 20 years post-retirement. 

The consequences of this underestimation are stark. Many retirees outlive their savings, placing pressure on families, social welfare systems, and personal well-being. A 2023 Sanlam Benchmark Survey found that more than 60% of retirees were unable to maintain their standard of living post-retirement, largely due to inadequate savings compounded by underappreciated longevity (Sanlam, 2023). 

Beyond financial security, longevity literacy also impacts decisions around healthcare, living arrangements, and intergenerational support. For instance, if individuals underestimate their lifespan, they may delay investing in annuities or long-term care solutions that could offer security later in life. 

At PW Harvey & Co., we advocate for a shift in retirement planning paradigms — one that places longevity literacy at the core of financial strategy. This means encouraging individuals to: 

• Regularly reassess their expected lifespan using updated actuarial data. 
• Model scenarios that project income sustainability into their 90s or beyond. 
• Consider hybrid retirement options, such as phased retirement or part-time work, which can ease financial pressure and maintain social engagement. 

Financial advisors play a pivotal role in bridging the gap. By educating clients about realistic life expectancy and incorporating longevity scenarios into financial plans, we empower South Africans to retire with confidence, not guesswork. 

Retirement should be a time of fulfilment, not fear. Elevating longevity literacy can help ensure that more South Africans don’t just reach retirement — they thrive through it.
