Congratulations! You hit the number.

You know the one: the figure you've been mentally circling for years. The amount that was supposed to mean you're done, finished, free of the work grind. You hit it, or you're close, and retirement is finally starting to feel real.

Here's the part nobody puts on the brochure: the number was probably, well, a little optimistic.

Not because you did anything wrong and not because your math was bad. Nope...it's because retirement has a way of introducing expenses that didn't exist while you were working (at least, not in the same way) - and some expenses that feel, well, new. Some of them are predictable, in hindsight. Some of them will genuinely surprise you. And a few of them will show up wearing a smile, holding a plane ticket, and asking if you want to come along.

In this post we're going to walk through four of the biggest cost categories that catch pre-retirees off guard: taxes on retirement income, healthcare before Medicare kicks in, the sinister (too strong a word??) expense of helping your kids, and healthcare costs later in retirement when things get more complicated. We'll keep it honest, we'll keep it real, and I promise we'll have at least a little fun with it. A little.

The Tax Bill You Didn't See Coming

Most people spend their working years thinking about taxes as something that happens to their paycheck. Your employer handles the withholding, you file in April, life moves on.

Retirement sometimes as a way of changing that relationship...in ways that genuinely catch people off guard.

Here's the thing about all that money sitting in your (pre-tax) 401(k) or Traditional IRA: it has never been taxed.

Not once.

The government has been very patient, and very quiet, and they are absolutely planning to collect. Every dollar you pull out in retirement is ordinary income. Add Social Security on top of that (yes, up to 85% of your Social Security benefit can be taxable depending on your income), and suddenly your retirement income plan has a tax problem baked right into it.

This is why the years between retirement and when required minimum distributions kick in at age 73 (75 if you were born in 1960 or later!) are so important. That window is often the best opportunity to do Roth conversions at a relatively lower tax rate, moving money from pre-tax accounts into tax-free Roth accounts before the IRS forces your hand. Miss that window, and you may find yourself taking larger taxable withdrawals than you wanted, in years where your income is already higher than expected.

Jack and Jane, a couple I work with in a composite example I use, assumed their taxes would drop in retirement. They were partially right. But between Social Security, RMDs, and a small pension Jack had from an earlier job, their taxable income in retirement looked a lot like their taxable income during their working years. The Roth conversion opportunity was sitting right in front of them for three years. They just didn't know to look for it.

Healthcare Before Medicare: The Gap Nobody Budgets For

Medicare starts at 65. Retirement, for a lot of people, starts earlier than that.

If you retire at 62 and Medicare doesn't start until 65, you have a three-year gap to fill. And if you've been covered by an employer plan for most of your career, you may have very little sense of what health insurance actually costs when you're buying it yourself.

Spoiler: it is not cheap.

Marketplace premiums for a couple in their early 60s can run anywhere from $1,200 to over $2,000 a month depending on the plan, the state, and the coverage level. That's before deductibles, copays, and the particular joy of discovering that your preferred doctor is out of network.

This one expense alone can meaningfully shift the math on early retirement. I've sat across from couples who were financially ready to retire at 62 by almost every measure, except this one. Bridging to Medicare became a real part of the conversation, sometimes even influencing the retirement date itself. Check out this post on how to manage healthcare costs when retiring pre-65.

If early retirement is part of your plan, healthcare before Medicare deserves its own line item. Not a footnote. Its own line.

The Kids. Oh, The Kids.

Nobody retires planning to stop loving their children. That's the trap.

This is the expense category that gets the least attention in retirement planning conversations and causes some of the most consistent, low-grade financial pressure I see in real life. It rarely shows up as one big number. It shows up as a series of completely reasonable, completely understandable decisions made out of love.

The wedding contribution. The down payment help. The month the grandkids needed new gear for school and you were just there. The adult child who hit a rough patch and needed a bridge loan that both of you knew would never quite be repaid. The family vacation you hosted because you wanted everyone together and you could make it happen.

None of these are mistakes. Most of them are some of the best money you'll ever spend. But they are real dollars leaving a portfolio that now has no new contributions coming in. And when they happen repeatedly, they can quietly reshape a retirement income plan.

The conversation I try to have with clients is this: generosity is a value worth planning for. If helping your kids and being present for your grandkids matters to you, let's build that into the plan intentionally. Let's put a number on it, or at least a range, so it's a decision and not a surprise.

Healthcare Later in Retirement: The Second Wave

You made it to Medicare. Congratulations, genuinely. But Medicare is not free, and it does not cover everything.

Premiums for Medicare Parts B and D, plus a supplemental Medigap policy, can run $400 to $600 a month per person, sometimes more. And if your income in retirement is above certain thresholds, you'll pay IRMAA surcharges on top of that. IRMAA, or Income Related Monthly Adjustment Amount, is the IRS's polite way of saying that higher earners pay more for Medicare. It's income-based, it looks back two years, and it can show up unexpectedly if you had a high-income year from a Roth conversion, a large withdrawal, or the sale of an asset.

Then there's dental, vision, and hearing. Medicare largely doesn't cover them. For a couple in their 70s and 80s, those costs add up faster than most people anticipate.

And beyond all of that sits long-term care, which deserves its own conversation entirely. If you want to go deeper on that one, I wrote about it recently in a post called "I Thought We'd Be Fine. Then My Husband Got Sick." It's worth a read.

The honest summary is this: healthcare is not a retirement expense that peaks and then goes away. It tends to grow over time, often at a rate faster than general inflation. A retirement income plan that doesn't account for that growth is working with incomplete information.

So What Do You Do With All of This?

None of this is meant to suggest that retirement isn't worth it or that the number doesn't matter. It does. But the number is a starting point, not a finish line.

The goal of a good retirement plan is not just to accumulate enough. It's to understand what "enough" actually has to cover, across a retirement that could last 25 or 30 years, through tax changes, health changes, family changes, and a cost of living that doesn't stay politely still.

That's the work. And honestly, it's some of the most meaningful work I get to do. If you've been following along on The Perfect Retirement Plan? on YouTube (or on the podcast webpage here on the site), you know that's what the whole show is built around. Real conversations about what retirement actually looks like, not just the highlight reel.

Remember, it's not about having the smartest financial advisor, the most money saved, or the highest probability of retirement success. The perfect retirement plan for you is the one you act on!
