How to Retire at 58: Step-by-Step Plan

Retire at 58, and you may have a retirement lasting four decades or more. Planning for that span of time means accounting for inflation and healthcare costs before Medicare. You’ll also face a delay in Social Security benefits. Meanwhile, consider how early withdrawals from retirement accounts are taxed and whether your savings can sustain growing annual expenses.

Consider working with a financial advisor for help as you put together your retirement plan.

Estimate Your Retirement Expenses

The first step is to calculate the annual expenses you expect to incur in a comfortable retirement. 

This depends heavily on your lifestyle and personal needs, as well as where you live. A city dweller who rents will need to anticipate ongoing housing payments, whereas a homeowner who owns their home outright will not. If you want to travel, this should be in your budget, whereas a homebody may require less cash.

Don’t just ballpark this. To maintain your current standard of living based on today’s spending, how much retirement income would you need per year? Start there, then adjust based on reasonable expectations. Reviewing your bank and credit card statements can help.

If you’re young, don’t forget that your standard of living will probably increase. Also, remember to account for insurance expenses during the seven years before you can enroll in Medicare. Finally, make a reasonable effort to estimate how inflation will affect your projected expenses.

Accounting for Healthcare Costs

This may be your single greatest retirement expense, as you’ll have seven years between losing employer benefits and becoming eligible for Medicare. 

First, find out what private insurance will cost after you retire. You can’t know for sure, but estimate how much you’ll need each year for premiums and other costs on a single-payer plan. Include that in your cost estimates when deciding how much you need to retire.

Second, determine how much additional money you will need for healthcare once you enroll in Medicare. Medicare significantly reduces your expenses, though not entirely. It is not a comprehensive program. This isn’t unique to early retirees, but everyone should prepare for medical costs.

For reference, a 65-year-old who retired in 2025 can expect to spend approximately $172,000 on health care in retirement, according to Fidelity’s annual Retiree Health Care Cost Estimate. ¹ Therefore, retiring at age 58 will mean spending considerably more since you’ll need to obtain private insurance for seven more years.

Planning Your Retirement Income

If you assume a 100-year life expectancy, retiring at 58 means that you’ll need 42 years’ worth of income. Suppose you need $50,000 from your investments in your first year. This will help you cover your living expenses. Since inflation reduces your purchasing power, you’ll need more than $50,000 in withdrawals each year after that.

If you expect to increase the size of your withdrawal by 2.5% each year to match the estimated inflation rate, you’ll need approximately $1.34 million in savings by age 58. This also assumes your investment portfolio will grow by a modest average of 5% year.

However, don’t forget to account for Social Security and any pension income you can expect to collect in retirement. You won’t be eligible to collect Social Security until age 62. ² Using a Social Security calculator, estimate how much your benefits will be based on when you start to collect them. For reference, the average monthly benefit for a retired worker was around $2,071 per month in January 2026. ³

How Long Will Your Retirement Savings Need to Last?

A key consideration is how many years your nest egg needs to last. 

To retire at 58, you are essentially adding up to 12 years to your retirement plan. While difficult to pin down, a conservative rule of thumb nowadays is to plan on living until you’re 100. This may seem like a stretch, but the CDC reports that life expectancy actually rose in 2024 to 79 years. ⁴ As healthcare continues to improve, that number will almost certainly improve every year.

You can use the Social Security Administration life expectancy calculator above, but financial advisors recommend adding five to 10 years to the results, depending on how conservatively you want to plan.

Don’t underestimate this, as the longevity risks of underestimating your own lifespan are serious. In your early retirement, you can always try to go back to work. However, in your 90s with failing health, it will likely be impossible to do so.

Anticipating Your Income in Retirement 

Cash flow in retirement will come from two sources: the government and private retirement savings accounts, such as IRAs and 401(k)s. It’s imperative to understand what each of these two sources can actually deliver.

Social Security Benefits

If you retire at 58, you will have anywhere from four to 12 years between when you retire and when you begin collecting Social Security. Therefore, you’ll need to save enough to cover this gap.

The earliest you can start collecting Social Security benefits is age 62. ⁵ However, the monthly payments will be less than 100% of what you would receive if you waited until the full retirement age of 67. ⁶ If, on the other hand, you delay your benefits past full retirement age, you will receive more.

When you reach age 70, you’re entitled to 124% of the monthly benefits you would have received starting at age 67. ⁷ However, after this point, there are no more increases in monthly benefits. (Note: All figures in this article apply to people born in the year 1960 or later.) 

Also, keep in mind that you cannot enroll in Medicare until age 65. ⁸

In 2026, the maximum monthly benefit at full retirement age is $4,152, while the most a person can collect at age 70 is $5,181. On the other hand, the cap on benefits at 62 is $2,969 per month. ⁹

Retirement Account Withdrawals

If you want to retire at 58, you must account for the rules surrounding tax-advantaged retirement accounts.

With a 401(k), you ordinarily cannot withdraw money penalty-free before age 59 ½. ¹⁰ However, there is an exception called the Rule of 55. ¹¹ Under this rule, the IRS allows you to begin making standard withdrawals from a 401(k) account if you leave your job during or after the year you turn 55. This rule also applies to similar programs, such as a 403(a) or 403(b).

The Rule of 55 does not apply to IRAs and Roth IRAs. If you withdraw money from either of these programs before turning 59 ½ years old, you pay extra taxes on the withdrawals unless you are eligible for an exemption. ¹²

For those retiring at 58, this is a relatively minor difference. You can begin making 401(k) withdrawals immediately, and you can begin withdrawing money from your IRA within 18 months of retirement at most.

This means that, so long as you anticipate that 18-month gap, you can include your retirement accounts in your early retirement planning.

Managing Your Investment Portfolio’s Asset Allocation

Your asset allocation is critical because it will help determine how long your investment portfolio must sustain you.

However, this doesn’t mean investors should rid themselves of stocks, says Morningstar’s John Rekenthaler. Equity-heavy portfolios support higher safe withdrawal rates than bond-heavy ones. They may also produce significant surpluses, even after 30 years of retirement spending.

While past results don’t guarantee future performance, equities should play an even larger role in a retiree’s investment portfolio. That’s all the more true given continual expansions of longevity.

“Should the future resemble the past, the lesson will remain valid. Retirees should invest heavily in equities, most likely more than they currently do,” Rekenthaler said. “But the advice rests upon that initial assumption.”

How to Cover the Gap Before Social Security and Medicare

Retiring at 58 creates a defined gap between leaving work and receiving government benefits. During this period, there is no Social Security income and no access to Medicare, while living expenses continue. Planning for this gap means determining your sources of income and how long each source needs to last.

The first source is typically taxable savings, such as brokerage accounts, cash reserves and other non-retirement assets. These can all be used without age-based penalties. You can draw on these first to cover everyday expenses and insurance premiums before tapping tax-advantaged accounts.

Employer retirement plans may also play a role. If you leave your job in or after the year you turn 55, the Rule of 55 allows penalty-free withdrawals from that employer’s 401(k). This can provide steady income until age 59½, when IRA withdrawals also become available. The timing of these withdrawals matters because they are taxed as ordinary income.

Roth accounts offer additional flexibility, allowing you to withdraw Roth IRA contributions at any time without taxes or penalties. Meanwhile, earnings generally require waiting until age 59½ and meeting holding rules. ¹³ Some early retirees use Roth contributions to smooth income during low-tax years, while leaving earnings invested longer.

The key checkpoint is whether your available income sources can cover the full gap without forcing large withdrawals later. Mapping out which accounts are used each year, and how those withdrawals affect taxes and future balances, helps reduce the risk of running short before Social Security and Medicare begin.

How an Advisor Can Help You Build a Comprehensive Plan

If you plan to retire at 58, financial advice becomes especially useful once your decisions start overlapping.

You are no longer deciding only how much to save. Instead, you are deciding how to fund years without Social Security, how to cover private health insurance and which accounts to draw from first without creating tax problems later.

These often require trade-offs that can have long-term effects. You may need to choose between using taxable assets and taking Rule of 55 withdrawals. You will also need to decide whether to delay Social Security versus preserving portfolio balance and whether you should pay higher health insurance costs now versus higher taxes later. These choices interact, meaning one decision changes the outcome of another.

An advisor helps you test those interactions in several ways.

• Building year-by-year cash flow projections from age 58 through Medicare eligibility
• Modeling different Social Security start dates
• Comparing withdrawal sequences across taxable, traditional, and Roth accounts
• Estimating how inflation and healthcare costs affect sustainability

Advisors also review asset allocation in the context of a 40-year retirement, not a standard 25-year horizon.

Be sure to ask your financial advisor targeted questions, such as these.

• Which accounts should I use between 58 and 62?
• How much can I withdraw before pushing myself into a higher tax bracket?
• Does delaying Social Security improve my long-term outcome if markets underperform early?
• How much can my plan absorb private insurance costs before adjustments are needed?

The value of advice at this stage comes from timing and downside control. Mistakes made early in retirement compound forward, while missed tax opportunities are often temporary.

As complexity increases, coordination matters more than optimization in one area, and that coordination helps keep your plan workable across decades rather than just the first few years.

Bottom Line

Planning to retire at 58 requires much the same process as planning for any other retirement stage. The key difference is anticipating a gap in government benefits and the loss of income during peak earning years. Aside from that, you must estimate what you’ll need each year to ensure your funds last throughout your golden years.
