Life Expectancy

Life expectancy is the average number of years a person can expect to live. It is generally calculated from either year of birth or any specific age. Worldwide, the best predictors of life expectancy are:

  • Lifestyle factors: smoking, poor diet, lack of exercise, nutrition factors
  • Genetic factors: predisposition to disease
  • Environmental factors (such as water, air quality)
  • Access to medical care
  • Income and education level

There may be a number of determinants that influence our life expectancies in retirement. For example, three of them are:

  1. Mental: your state of mind now and in retirement; how you handle stress
  2. Sociological: how you perceive how your reference group sees you
  3. Psychological: how old you see yourself as being

A consideration of these points gives rise to a compelling observation: if a person doesn’t have a positive self-image and a sense of purpose, the retiree can expect their quality of life to deteriorate.

For How Long Will You Be Retired?

The earlier you retire, the longer you’ll need your money to last. If you have good genes, healthy lifestyle habits and are currently healthy, it’s not out of line to use age 95 for your life expectancy in your retirement modelling and calculations.

You’re planning in case you live, so you can ensure your lifestyle won’t be compromised if you do live into your 80s or 90s.
