Retirement Planning | 6-minute read

You planned for the basics. But there are hidden costs that quietly drain retirement savings every year. Here’s what to watch for.
Most people spend decades saving for retirement, carefully budgeting for housing, food, and travel. But when the paychecks stop coming, a surprising number of retirees discover that their carefully planned budget has holes in it. Unexpected costs show up early, they compound over time, and they can throw even well-prepared people off course.
Per research from Mutual of Omaha, approximately 36% of retirees have faced unexpected costs since retiring and only 59% have at least three months of emergency savings set aside to handle them.
This guide covers seven of the most common and most overlooked retirement expenses, explained in plain language so you can plan ahead and protect the savings you worked so hard to build.
1. The healthcare gap Medicare doesn’t fill
Many people assume that once they turn 65 and qualify for Medicare, their medical costs are largely covered. That assumption can be expensive. According to Fidelity Investments, a 65 year old retiring in 2025 can expect to spend an average of $172,500 on medical and healthcare expenses throughout retirement – and for a married couple, that figure reaches $345,000. And that doesn’t even include dental, most vision care, or hearing aids.
Medicare Part B premiums alone start at $185 per month in 2025, and you are still responsible for deductibles, copayments, and coinsurance on top of that, per Citizens Bank 2025. Prescription drug coverage through Medicare Part D adds an average premium of $46.50 per month.
What Medicare doesn’t cover:
routine dental exams, dentures, routine eye exams, eyeglasses, hearing aids, and most hearing tests. These are often called the “dental, vision, and hearing gap” – and they can cost thousands of dollars a year out of pocket.

Long – term care: the cost that surprises everyone
People rarely plan for the possibility that they might need daily help with bathing, dressing, or getting around. But statistically, most people eventually do. And the costs are staggering.
According to the 2024 Genworth Cost of Care Survey, the national median cost of a home health aide runs about $77,792 per year. A semi – private room in a nursing home comes in at a median of $111,325 per year, while a private room jumps to $127,750. AARP reports that assisted living communities saw costs rise 10% from 2023 to 2024, reaching a national median of $70,800 per year.

Standard Medicare does not cover ongoing nursing home or assisted living care. Medicaid can help, but typically only after you have spent most of your assets down to very low levels.

Dental, vision, and hearing: three bills Medicare ignores
Original Medicare (Parts A and B) does not cover routine dental cleanings, fillings, dentures, routine eye exams, eyeglasses, or hearing aids, as confirmed by Medicare’s own published coverage guidelines. For many retirees, these three categories alone represent hundreds or even thousands of dollars per year in unexpected costs.
Consider what a single year might look like without coverage: a dental crown can run $1,500 out of pocket; new progressive eyeglass lenses can cost $600; and a pair of quality hearing aids is often quoted between $2,000 and $6,000 (per Palmetto Mutual’s 2025 consumer guide). Hearing loss is particularly common as we age, and researchers indicate that untreated hearing loss has been linked to social isolation, depression, and an increased risk of cognitive decline.
The good news: Medicare Advantage plans increasingly include some dental, vision, and hearing coverage. As of 2025 and going into 2026, nearly 90% of individual Medicare Advantage plans offer some form of these benefits (per KFF’s Medicare Advantage 2025 Spotlight report) – though coverage depth varies significantly from plan to plan.

What you can do
Compare Medicare Advantage plans in your area specifically for dental, vision, and hearing benefits. You can also purchase standalone dental and vision plans. Private dental insurance for seniors typically runs between $30 and $70 per month, depending on the plan and your location.
Home maintenance and “aging in place” upgrades
Retiring with a paid – off home feels like a win – and it is. But owning a home still means paying for it. Property taxes, homeowner’s insurance, utilities, and routine maintenance don’t stop when you stop working. And as your home ages (and as you do), unexpected repair bills will arise.
Here’s what many people don’t factor in: the cost of making your home safer and more accessible as you get older. A survey by American Advisors Group found that around 82% of seniors would prefer to remain in their current home for the rest of their lives. This is a great goal, but it often requires real investment. Doorways may need to be widened for wheelchair access, a bathroom may need to be renovated with grab bars and a walk – in shower, or a bedroom may need to be relocated to the main floor.
Home insurance is also rising sharply across the country. The Consumer Federation of America shows the typical homeowner’s annual premium increased by an average of 24% between 2021 and 2024 – and analysts at Insurify forecast an additional 8% increase in 2025, pushing the national average toward $3,520 per year.

Taxes in retirement: they don’t disappear
Many retirees assume their tax bills will shrink dramatically once they stop working. Sometimes they do – but often not as much as expected. Social Security benefits, pension income, and withdrawals from traditional IRAs and 401(k) accounts can all be subject to federal income tax.
At the federal level, Fidelity confirms that up to 85% of your Social Security benefit can be taxable, depending on your combined income from all sources. On the state level, nine states still tax Social Security benefits in 2025: Colorado, Connecticut, Minnesota, Montana, New Mexico, Rhode Island, Utah, Vermont, and West Virginia (per The Motley Fool).
Required Minimum Distributions (RMDs): Once you reach age 73, the IRS requires you to start taking annual withdrawals from your traditional IRA or 401(k) – whether you need the money or not. These withdrawals are taxed as ordinary income, which can push you into a higher tax bracket or increase the taxable portion of your Social Security benefits.
Rising home values have also caused property taxes to climb in many areas, even for retirees who have lived in the same house for decades.

Inflation: the slow leak in your retirement savings
Inflation never sends you a bill. It just quietly makes everything cost more over time. And for retirees living on a fixed income, this steady erosion of purchasing power is one of the most serious long- term threats to financial security.
If inflation holds at its long – term average of around 3%, The Motley Fool indicates your purchasing power could be cut roughly in half over 25 years. That means if you’ve planned to live on $60,000 per year in retirement, by your late 80s that same amount of money would only buy what $30,000 buys today.
Healthcare inflation is especially worrisome for retirees because medical costs rise faster than overall prices. The U.S. Bureau of Labor Statistics shows healthcare costs were rising at 3.9% annually as of late 2025, compared to the broader inflation rate of about 3%. Insurance is another area of concern: per AARP, home insurance surged 11% in 2023 and another 11.4% in 2024, while auto insurance premiums have been rising at double or even triple the overall inflation rate.


Helping family: the generous expense nobody budgets for
This one rarely appears in retirement planning guides, but it shows up in real life constantly. Adult children who hit financial trouble, grandchildren’s education costs, helping aging parents who need care, or contributing to family emergencies – these are expenses that feel impossible to say no to, and they can quietly drain a retirement nest egg.
Many retirees are caught between two generations: children who may still need financial support and elderly parents who may need help with living expenses or care. This situation is common enough that it has a name: the “sandwich generation.” And while the emotional pull to help is completely understandable, financial advisors consistently flag family financial support as one of the most underestimated retirement expenses.
A practical perspective: Financial planners sometimes compare retirement savings to an airplane oxygen mask: you need to secure your own before helping others. If you deplete your savings helping family members, you may eventually become financially dependent on them, which creates a bigger burden in the long run.

The best time to plan for these costs is before they arrive
None of these expenses have to derail a comfortable retirement. But they do require awareness and planning. Talk with a certified financial planner who specializes in retirement income, review your Medicare options each year, and build a budget that accounts for the unexpected – because in retirement, the unexpected tends to show up right on schedule.
