Judging your retirement by your portfolio balance is a little like judging your health by your weight.
Useful. Nowhere near the whole story.
A framework published in the Journal of Financial Planning treats retirement as four connected risks to manage, rather than one investment problem to solve.
Longevity. The oldest concern in retirement planning. The hard part isn't a long life — it's not knowing. A plan has to hold up whether retirement runs 15 years or 35, and those can be very different plans.
Market. Volatility, inflation, and the order returns arrive in. Two retirements with identical average returns can end up in very different places depending on when the good and bad years happen.
Health. More than 9 in 10 adults age 65 and older live with at least one chronic condition, according to CDC data. A market downturn is usually something you move through. A serious health event can permanently change what a household spends.
Decision. Retirement brings hundreds of financial decisions, made across decades. Research suggests the ability to make them well peaks in midlife and gradually declines from there. Market declines are episodic. Cognitive change usually isn't.
And they don't stay separate. A health event raises monthly expenses, which means larger withdrawals that happen to land during a downturn. If retirement runs longer than expected, those larger withdrawals have more time to add up.
One change. Several consequences.
A portfolio balance tells you where you stand today. It doesn't tell you how the pieces of your life might move together over 30 years.
