“How much do I need to retire?” is the question almost every pre-retiree eventually asks, and the answer the internet usually gives is somewhere between useless and misleading. A single number, a multiple of your salary, or a rule of thumb calibrated for someone with a fraction of your assets.
The reality is that the right number for you depends on a set of variables that are entirely specific to your situation. Two people can retire the same year with the same portfolio balance and have very different outcomes depending on how their income is structured, how their withdrawals are sequenced, and how well their plan accounts for taxes, healthcare, and longevity.
Why “How Much Do I Need to Retire” Doesn’t Have a Simple Answer
The most common shorthand you’ll hear is the 4% rule: save 25 times your annual expenses and you can withdraw 4% per year indefinitely. It’s a reasonable starting point and it’s grounded in legitimate research, but it was developed using historical data that may not reflect what the next 30 years look like, and it doesn’t account for the complexity most high-net-worth retirees are actually navigating.
Your retirement number isn’t just a portfolio balance. It’s the intersection of your spending needs, your income sources, your tax situation, your healthcare costs, and how long you’re likely to need the money to last. Each of those variables can shift the number significantly in either direction.
Someone with $2 million who retires at 62 with no pension, high healthcare costs, and plans to travel extensively faces a very different math problem than someone with $1.5 million who retires at 65 with a pension covering core expenses and Social Security about to kick in. The first person might be underfunded. The second might be in excellent shape.
Start With What You Actually Spend
Before any portfolio calculation makes sense, you need a clear picture of what retirement actually costs you. Not what you think it costs, what the numbers say when you look carefully.
Most people underestimate retirement spending in the early years, when health is good and travel and lifestyle spending tend to be highest, and underestimate healthcare and long-term care costs in the later years. A well-designed retirement budget accounts for both phases, not just a single flat spending number projected forward.
It’s also worth separating essential expenses from discretionary ones. Knowing which costs are fixed and which are flexible gives you a meaningful lever to pull if markets don’t cooperate early in retirement. That flexibility has real financial value and should be part of how you think about your number.
Your Retirement Income Sources Change the Math Significantly
The portfolio balance you need in retirement depends heavily on how much guaranteed income you already have coming in. Social Security, pensions, and annuities that cover a meaningful portion of your essential expenses reduce the burden on your portfolio considerably.
A retiree whose essential expenses are fully covered by Social Security and a pension needs their portfolio to fund discretionary spending and handle unexpected costs. A retiree with no guaranteed income outside of Social Security needs their portfolio to do much more heavy lifting.
This is one reason Social Security timing is such an important decision. Delaying to 70 increases your benefit by roughly 8% per year past Full Retirement Age, which means a larger guaranteed income floor, which means less pressure on your portfolio. For someone with $1.5 million saved, maximizing Social Security can have the same practical effect as having an additional $200,000 to $300,000 in the portfolio.
If you’re within five years of retirement and haven’t modeled what your guaranteed income floor looks like, that’s one of the most valuable things you can do before you set a retirement date.
Taxes Are a Bigger Variable Than Most People Expect
Your pre-tax portfolio balance is not your retirement number. The IRS has a claim on every dollar you withdraw from a Traditional IRA or 401(k), and the effective tax rate on those withdrawals depends on your full income picture in any given year, including Social Security, other income sources, and Required Minimum Distributions that start at age 73.
For someone with $1.5 million in a Traditional IRA, the after-tax value of that account might be closer to $1.1 or $1.2 million depending on their bracket, state tax situation, and withdrawal strategy. That’s a meaningful gap, and it’s one that good planning can partially close through Roth conversions, withdrawal sequencing, and tax-aware distribution strategies.
The question isn’t just how much you have. It’s how much of it you actually get to keep.
This is part of why working with a fee-only fiduciary advisor matters for people in this situation. Tax planning and retirement income planning are inseparable, and an advisor who isn’t thinking about both simultaneously is leaving money on the table.
Healthcare Costs Before Medicare Are Often Underestimated
If you retire before 65 and lose employer-sponsored health coverage, the cost of bridging to Medicare can be significant. A couple in their early 60s purchasing coverage through the ACA marketplace can easily spend $1,500 to $2,500 per month or more depending on the plan and their income, which affects ACA subsidy eligibility as well.
This is a real cost that belongs in your retirement budget and your portfolio calculation. People who retire at 62 and haven’t accounted for three years of healthcare premiums sometimes find themselves spending down their portfolio faster than projected before Medicare even starts.
Long-term care is a separate conversation, but it belongs in any serious retirement readiness discussion. The average cost of assisted living or memory care in Colorado is substantial and rising. Not everyone will need it, but the financial consequences for those who do, without a plan in place, can be significant.
Sequence of Returns Risk Affects How Much You Need
Even if your portfolio balance looks adequate, the order in which market returns arrive in retirement can change the outcome significantly. A major market decline in the first two to three years of retirement, combined with ongoing withdrawals, can create a deficit that later recoveries don’t fully repair.
This means your retirement number isn’t just about the average return you expect. It’s about whether your plan can withstand a bad sequence early on without forcing you to make permanent lifestyle adjustments. A larger initial buffer, a cash reserve strategy, or a guaranteed income floor that reduces early portfolio withdrawals all affect how much you need to retire with confidence.
We covered this in depth in our sequence of returns risk article if you want to understand the mechanics more fully.
So What Is the Number?
For most people targeting a comfortable retirement with meaningful discretionary spending, no pension, and a desire to leave something to heirs, a reasonable range is somewhere between 20 and 30 times annual expenses, depending on retirement age, health, income structure, and tax situation. That’s a wide range, and that’s the point.
Retiring at 60 with no guaranteed income and high spending needs pushes you toward the higher end. Retiring at 67 with a pension covering core costs and a delayed Social Security benefit starting at 70 might allow for a smaller portfolio to support the same lifestyle.
The number also isn’t static. It should be stress-tested against scenarios including a down market in year one, higher-than-expected healthcare costs, a longer lifespan than you’re planning for, and the loss of a spouse. A plan that works under one set of assumptions but falls apart under reasonable alternatives isn’t a plan, it’s a hope.
What a Retirement Readiness Analysis Actually Looks Like
At Inclinevest, when we work through retirement readiness with a client, we’re looking at the full picture: spending needs across different phases of retirement, guaranteed income sources and timing, pre-tax and after-tax portfolio composition, Roth conversion opportunities, Social Security optimization, healthcare cost projections, and estate goals.
We run scenarios, not just averages. What happens if you live to 95? What happens if markets underperform in the first five years? What happens if one spouse needs long-term care at 80? The goal is a retirement plan that holds up across a range of realistic outcomes, not just the best-case version.
If you’re approaching retirement in the Denver metro area and want to work through what your number actually is, we’d be glad to start that conversation. You can also review our services and fees to understand how we work with clients.
Key Takeaways
- There’s no universal answer to how much you need to retire. The right number depends on your spending, income sources, tax situation, healthcare costs, and how long your money needs to last.
- Guaranteed income from Social Security and pensions significantly reduces the burden on your portfolio and can effectively replace several hundred thousand dollars in savings.
- Your pre-tax portfolio balance overstates what you actually have. Taxes on withdrawals from Traditional IRAs and 401(k)s are a real cost that belongs in your retirement math.
- Healthcare costs before Medicare and long-term care costs later in retirement are commonly underestimated and can materially affect how much you need.
- Sequence of returns risk means your plan needs to hold up in bad markets, not just average ones. Build in a buffer for a rough start.
- A retirement readiness analysis should include multiple scenarios, not just a single projection based on assumed average returns.
