A $900,000 401(k) is not worth more in nominal dollars than a $1.2 million 401(k). It can provide more retirement security relative to its owner’s needs if the 73-year-old has less time to fund, lower spending needs, or more income from Social Security, a pension, or other assets. The balances alone cannot tell you which retiree is better prepared.
The useful comparison is how much after-tax income each household needs from its savings, for how long, and with what tolerance for investment and inflation risk. “Worth more” might mean more dependable lifetime spending, more flexibility, or a larger inheritance; those are different goals.
Why age changes the comparison—but does not settle it
A 62-year-old may need savings to support a longer retirement than a 73-year-old. That longer horizon can mean more years of withdrawals and greater exposure to inflation and market downturns, particularly early in retirement. But age alone does not establish the actual planning horizon: either person could live much longer than expected, and the younger retiree may have wages or other income while the older one may have substantial expenses or dependents.
The right question is not simply which account is larger. It is whether each household’s combined resources can support its intended spending over its own horizon. The $900,000 account could be more adequate for one household; it is not inherently more valuable than the $1.2 million account.

Compare the resources each household can actually spend
Build the comparison around each household’s income and expenses, not the account balance in isolation. Social Security, pension income, employment, savings outside the 401(k), and other assets may reduce the withdrawals needed from retirement savings. Conversely, taxes and household costs affect how much of the balance translates into spendable income.
- Time horizon: Estimate how long savings may need to support spending. Do not assume the 73-year-old needs funds for only a short period.
- Spending target: Identify annual spending needs, separating essential expenses from costs that could be reduced after a market decline.
- Other income: Use actual Social Security estimates, pension amounts, expected work income, and other financial resources.
- Taxes and account types: Pretax 401(k), designated Roth, and after-tax assets do not produce identical spendable dollars. The information given here does not include the tax or household details needed to calculate after-tax income.
- Investment and inflation risk: Returns, inflation, portfolio mix, and losses early in retirement can change how long withdrawals last.
- Household goals: Marital status, survivor income, health, and a desire to leave an inheritance can change the appropriate trade-off between spending now and preserving assets.
Without those details, neither an after-tax income figure nor a personalized conclusion about which account is sufficient can be calculated.

What a withdrawal-rate estimate can—and cannot—show
Morningstar’s 2025 retirement-income research reported a 3.9% starting withdrawal rate for inflation-adjusted withdrawals over a modeled 30-year retirement, with a 90% probability of funds remaining at the end. The figure is a model result based on a selected portfolio and forward-looking assumptions, not a guarantee or an individualized recommendation. It excludes Social Security and other nonportfolio income; Morningstar discusses how guaranteed income and flexible spending affect the analysis. See Morningstar’s December 3, 2025 withdrawal-rate analysis.
Applying that same rate purely as arithmetic would produce a $35,100 first-year withdrawal from $900,000 and $46,800 from $1.2 million. Those amounts are illustrations of multiplying each balance by 3.9%, not separate Morningstar findings or personalized safe-spending amounts. The shared 30-year assumption may not fit either retiree, and the calculation does not account for either person’s other income, taxes, or spending needs.

Social Security is a separate decision that affects the income plan
Retirement benefits can generally be claimed from age 62 through 70, with delayed claiming after full retirement age increasing the benefit. The actual benefit depends on the person’s earnings record and birth year, so an estimate for each retiree is more useful than a general comparison by age. The Consumer Financial Protection Bureau states: “The amount of money you receive by claiming at age 62 is the lowest benefit you can claim.” Read its guide to planning a Social Security claiming age.
For the 62-year-old, claiming sooner or using savings to bridge income while delaying are distinct planning choices. The best fit depends on the household’s needs and circumstances; the account balance by itself does not determine when to claim.
At 73, required distributions are not a spending recommendation
Under current IRS guidance, required minimum distributions (RMDs) generally begin at age 73 for a 401(k) participant. A delay is generally available while the participant continues working for the employer sponsoring the plan, but not for a 5% owner; plan terms and individual facts matter. A plan may require distributions earlier. Designated Roth accounts have different lifetime RMD treatment under current IRS rules. Consult the IRS guidance on required minimum distributions and 401(k) distribution rules.
An RMD is a tax-law minimum distribution, not an instruction to spend the money or proof that a particular lifestyle is affordable. A plan’s distribution choices also depend on its provisions: benefits may be paid as a lump sum or, where offered, through options such as installments or a purchased annuity. Check the plan documents and the IRS pages on when a plan can distribute benefits and 401(k) plan requirements.

- Set each household’s spending target. Estimate annual needs and identify which expenses are essential or flexible.
- List income and assets outside the 401(k). Include actual Social Security estimates, pensions, work income, and other resources.
- Account for taxes. Determine how account type and household circumstances affect spendable income rather than treating every dollar in the balance as equivalent.
- Choose a realistic horizon and risk approach. Consider longevity, inflation, portfolio risk, and the ability to adjust spending after poor returns.
- Compare the result with household priorities. Decide whether the goal is reliable spending, flexibility, survivor protection, or leaving assets to heirs.
This framework can show why the smaller account might be enough for one household while the larger balance may be under pressure for another. It cannot produce a personalized verdict from age and balance alone.
