When planning for retirement, most people focus on the risks they can measure: Market volatility, inflation, withdrawal rates and how long their savings need to last.
Healthcare is usually handled differently. It’s often treated as a number to estimate, not something to actively manage, which can fall short of how these costs actually develop.

When care doesn’t hold up in real life, costs build into what might be called hidden “carry costs” (recurring out-of-pocket expenses such as extra appointments, repeated prescription changes and additional lab work) that aren’t fully captured in most retirement projections.
A 65-year-old couple may need roughly $315,000 after tax to cover healthcare expenses throughout retirement, excluding long-term care.
While that figure is often used as a baseline, it assumes a relatively stable path. It doesn’t fully account for the variability that can occur when chronic conditions become difficult to manage or care plans break down.
So the question isn’t only how much healthcare will cost. It’s how those costs build in the first place.
Why prevention matters for your finances
Prevention is often discussed as a health goal, but it also has direct financial implications. When chronic conditions are left untreated or managed inconsistently, they tend to become more complex over time.
What might have been manageable early on can turn into something that requires more frequent visits, more testing, more medication changes and more intensive care.
That progression is expensive, and in many cases, it could have been mitigated earlier. This matters even more in retirement, when income is typically fixed, and repeated out-of-pocket expenses can put real pressure on a carefully planned budget.
Prevention, in this context, isn’t just about avoiding illness. It’s about reducing downside risk and limiting how often manageable problems turn into high-cost events.
Why healthcare costs often come down to behavior
According to the CDC, nearly 90% of adults over age 65 live with at least one chronic condition, and many manage several. These conditions require ongoing care and consistent follow-through, which is where things can begin to break down.
If a care plan is hard to tolerate or doesn’t fit easily into someone’s routine, people adjust in small ways that add up over time. A dose of medication gets skipped, refills get delayed, follow-up visits are postponed, and sometimes the medication is stopped altogether.
Medication nonadherence alone has been linked to hundreds of billions in avoidable healthcare spending each year in the U.S. To put that in individual terms, research published in Annals of Internal Medicine estimates that nonadherence contributes to about 125,000 deaths and up to 25% of hospitalizations annually — each of which carries significant out-of-pocket costs for the patient or their family.
Whether care is followed consistently is not just a clinical issue, it is a cost driver.
In investing, this would be called execution risk. A strategy can look sound on paper, but if it can’t be followed consistently, the results break down. Most retirement plans assume regimens will be followed as prescribed. In reality, that’s often one of the least reliable assumptions in the entire plan.
Where personalized medicine can help
In practical terms, personalized medicine isn’t about cutting-edge technology. It’s about making sure a regimen is something the person can follow consistently day to day. Two people with the same diagnosis can respond very differently to the same regimen. Differences in tolerability, metabolism, sensitivities and daily routine all affect whether a plan is sustainable.
That’s where a more individualized approach can help. Adjusting dose, timing or delivery method can make care easier to follow consistently. In some cases, providers may also consider a compounded formulation — a medication prepared by a compounding pharmacy in a customized strength or form — when standard options may not meet an individual patient’s needs.
A fair question is whether more individualized care comes at a higher upfront cost. In some cases, it does. But for some patients, working with their healthcare provider to find a better-fitting care plan may help support more consistent follow-through over time.
How better-fit care can reduce costs over time: A real-world example
Consider a retiree managing a thyroid condition. A standard medication may address the diagnosis clinically, but if it causes side effects that make daily use inconsistent, instability tends to follow. Doses are missed, symptoms fluctuate, follow-up visits increase, and the prescription is adjusted — then adjusted again.
Each adjustment often comes with additional lab work, specialist visits and time spent navigating changes in care.
A thyroid panel typically costs $50 to $200 out of pocket; an endocrinologist visit can run $200 to $400 without strong insurance coverage. If a patient goes through three or four rounds of adjustments over two years, the ancillary costs alone could easily reach $2,000 to $5,000 — not counting the medication itself or any related hospitalizations.
Now imagine that earlier in the process, the patient works with their provider to adjust tolerability and routine. The condition still requires management, but the goal is a more stable experience with fewer adjustments needed over time .
The difference isn’t perfect outcomes. It’s a care plan designed to be more sustainable, which may support greater consistency over time.
A more practical way to plan for healthcare in retirement
Most people nearing retirement ask a simple question: How much will healthcare cost?
It’s a fair question, but it’s not the only one that matters. It’s also worth asking where care is most likely to break down and what would make it easier to maintain.
Retirement plans aren’t tested only by large, unexpected events. They’re shaped by everyday patterns — including how consistently care is followed, how often it needs to change and whether it becomes stable over time.
Healthcare expenses will always be part of retirement, but not all of those costs are unavoidable.
Retirement planning isn’t just about managing investments. It also depends on whether your care plan is something you can realistically stick with over time. Care that doesn’t hold up is often what makes costs spiral, and that’s a risk worth planning for.
Compounded medications are not FDA-approved and are prepared by licensed compounding pharmacies based on a practitioner’s prescription for an individual patient.
