How Much Do I Really Need to Retire?

Most people arrive at a number. Sometimes it's $1 million. Sometimes it's $2 million. Sometimes it's "enough to replace my income." And then they spend years wondering whether that number is right.

The honest answer is that the number alone rarely tells you what you actually need to know.

The "how much do I need" question is understandable. It's concrete. It gives you something to aim for. But it collapses a complex, dynamic situation into a single static target — and that's where it starts to mislead.

Here's why: your retirement isn't a single event. It's a 20-, 30-, or even 40-year stretch of life with changing expenses, changing income sources, changing tax situations, and changing health needs. A number that looks sufficient at 65 may look very different at 75 or 85.

The question I find more useful is not "how much do I need?" but "what happens if I retire with what I have?"

You've probably heard the 4% rule — the idea that you can withdraw 4% of your portfolio each year and not run out of money over a 30-year retirement. It's a reasonable starting point, but it was developed under specific market conditions and doesn't account for your actual situation.

It doesn't account for:

• Whether you have a pension or Social Security income that covers part of your expenses
• The tax treatment of your accounts (pre-tax IRA vs. Roth vs. taxable brokerage)
• Whether your spending is likely to increase, decrease, or stay flat over time
• What happens if markets have a rough stretch in your first few years of retirement
• Whether you want to leave something to your children or a cause you care about

A rule of thumb is a starting point. It's not a plan.

In my experience, the clients who retire with the most confidence aren't necessarily the ones with the largest portfolios. They're the ones who understand their situation clearly enough to answer a few key questions:

Where will your income come from? Social Security, a pension, portfolio withdrawals, rental income, part-time work — the mix matters enormously. A client with $800,000 in savings and a pension that covers 70% of their expenses is in a very different position than someone with $1.5 million and no guaranteed income at all.

What will you actually spend? Not what you spend now — what you'll spend in retirement. For many people, some expenses go down (commuting, work clothes, saving for retirement itself) while others go up (travel, healthcare, helping adult children). Getting this right matters more than most people realize.

How will taxes affect your withdrawals? If most of your savings are in a traditional IRA or 401(k), every dollar you withdraw is taxable income. That changes the math significantly. A $1.5 million IRA isn't $1.5 million of spending power — it's $1.5 million minus whatever you'll owe in taxes over the years you draw it down.

What does your healthcare picture look like? For people retiring before 65, healthcare costs before Medicare eligibility can be substantial. Even after 65, Medicare premiums, supplemental coverage, and out-of-pocket costs add up. This is one of the most underestimated expenses in retirement planning.

One thing that surprises many people is how much the timing of market returns matters in retirement — not just the average return over time.

If markets decline significantly in the first few years of your retirement, and you're withdrawing from your portfolio at the same time, you're selling shares at lower prices to fund your expenses. That leaves fewer shares to recover when markets eventually rebound. The same average return over 20 years can produce very different outcomes depending on when the good years and bad years happen.

This is called sequence-of-returns risk, and it's one of the reasons that "I'll just earn 7% on average" isn't a complete answer to the retirement readiness question.

Rather than asking "do I have enough?" I'd encourage you to ask: "What does my retirement actually look like under different scenarios?"

• What happens if I retire now versus in two years?
• What happens if I spend $8,000 a month versus $10,000?
• What happens if markets are flat for the first five years?
• What happens if I delay Social Security until 70?
• What happens if I need long-term care at 80?

These aren't meant to be frightening questions. They're meant to be clarifying ones. Some scenarios will show you that you're in better shape than you thought. Others will show you where the real risks are — and what you can do about them before you retire.

The clients I work with who feel most confident about retirement aren't the ones who hit a magic number. They're the ones who've actually looked at the pathways — who understand what their retirement looks like under a range of realistic scenarios, not just the best case.

That confidence doesn't come from a calculator. It comes from doing the work to understand your specific situation clearly enough that the decision stops feeling like a guess.

If you're asking "how much do I really need?" — that's the right instinct. The next step is to go deeper than the number.
