The Retirement Risk You're Probably Not Planning For

For a lot of people, the real anxiety isn’t outliving a portfolio. It’s health. It’s the cost of care. It’s the fear of becoming a burden, or of watching a single medical event drain the savings that were supposed to last. Those worries don’t map neatly onto a market-return assumption, which may be exactly why the standard planning process tends to skip past them.

That gap matters, because health-related costs behave very differently from investment risk. A down market recovers. A long-term care need often does not, and it can run for years. The cost of extended care in many parts of the country now rivals or exceeds what a comfortable household spends on everything else combined. Yet it’s frequently treated as a footnote, a line item to look into later, rather than a central planning question.

Part of the problem is that these risks are uncomfortable to model. You can’t put a clean probability on your own future health, and no one enjoys imagining decline. So the conversation drifts toward the parts that feel more solvable, like asset allocation and withdrawal rates, and away from the parts that actually determine whether a retirement holds together.

A better approach starts by naming the real fears out loud. What happens if one spouse needs care for five years? Who would provide it, and what would it cost? Is there a plan for the surviving spouse, whose expenses often don’t fall as much as people expect? These questions rarely have tidy answers, but working through them tends to reshape the whole plan. It changes decisions about insurance, about housing, about how much cash to keep on hand, and about which assets you would tap first in a crisis.
Longevity and markets still matter. They’re just not the entire story, and they may not even be the part of the story that worries you most. A plan that only optimizes for portfolio survival can still leave you exposed to the very thing you were afraid of in the first place.

If your retirement plan is mostly a set of return assumptions and a withdrawal rate, it’s worth asking what it says about the harder stuff. That’s usually where the real security, or the real gap, turns out to be.
