How Much Should You Have in Your 401(k) at Every Age?

The most widely used retirement benchmarks say you need to save 1x your salary by 30, 3x by 40, 6x by 50, and 10x by 67. Those numbers come from Fidelity’s retirement guidelines, and they are useful shorthand built on assumptions that may not match your life. The number you are supposed to hit might be too high or too low, depending on your actual spending needs.

What the Benchmarks Actually Assume

The guidelines assume you will need to replace 70% to 80% of your pre-retirement income and that Social Security will cover a meaningful portion of that gap. For a median earner, Social Security replaces around 40% of pre-retirement income. The 401(k) benchmark is designed to cover the rest. That math works if your spending in retirement tracks your pre-retirement income, but for many people it does not.

Someone with a paid-off home, no dependents, and modest travel habits may need to replace only 55% to 60% of their income. At that level, the 6x benchmark at age 50 is more than enough. Someone supporting adult children, carrying a mortgage into retirement, or planning extensive travel could need 12x or more. The benchmark does not know which one you are.

The Gap Between the Benchmark and Reality

Vanguard’s preliminary “How America Saves 2026” data, which tracks nearly 5 million 401(k) participants, reveals a persistent gap between the average balance and what most savers actually hold. Driven by strong market performance across equities and bonds in 2025, the average account balance rose 13% to $167,970, setting a new record. The median balance reached $44,115, a 16% gain year over year. Even so, that gap between average and median is large because a relatively small number of participants with very high balances pull the average upward.

The median number tells a more honest story for workers approaching retirement. Those aged 45 to 54 have a median 401(k) balance of $67,796, and those aged 55 to 64 have a median of $95,642, based on Vanguard’s 2025 report covering year-end 2024 data. Meanwhile, a 60-year-old earning $80,000 who follows the Fidelity benchmark should have about $640,000 saved. The typical person in that age group has less than $100,000, meaning tens of millions of households face a savings gap that cannot be closed with small adjustments.

The strain is showing in withdrawal patterns as well. Hardship withdrawals from 401(k) accounts hit a record 6% in 2026, triple the pre-pandemic average, with roughly 35% of those tapping funds citing the need to prevent foreclosure or eviction. For a growing segment of the workforce, the 401(k) is functioning as a high-stakes emergency fund rather than a long-term retirement vehicle.

Why Averages Mislead and Medians Tell the Truth

The average is skewed by high earners who max contributions every year, receive generous employer matches, and have been investing since their 20s. The median reflects the person in the middle of the distribution, a far more honest picture of where most savers actually stand. When you read that Americans have “record high” 401(k) balances, that headline reflects the average. Most savers are not in the top tier pulling the average upward.

Benchmarks are typically calibrated against averages, not medians. If you are measuring yourself against the wrong number, you may feel ahead of schedule when you are not, or feel hopelessly behind when you are actually fine given your specific spending needs.

The Contribution Window Most People Miss

If you are behind on the benchmarks and still working, the contribution rules start working in your favor as you get older. For 2026, the standard 401(k) contribution limit is $24,500. Workers aged 50 and older can add a catch-up contribution of $8,000, bringing the total to $32,500 per year.

SECURE 2.0 added a provision that many participants have not heard of. Workers who are age 60, 61, 62, or 63 in 2026 qualify for a “super catch-up” contribution of $11,250 instead of the regular $8,000, raising the total annual limit to $35,750. For someone who is behind on savings but still earning a solid income, those four years create a powerful window to make up a large part of the gap.

The 2026 High-Earner Roth Mandate

A significant regulatory shift under SECURE 2.0 changes how high earners must handle extra savings beginning in 2026. Any worker whose prior-year FICA wages exceeded $150,000 is required to direct all catch-up contributions into a Roth (after-tax) account. This disrupts traditional pre-tax sheltering strategies for upper-income earners and requires those affected to verify that their employer’s plan actually supports an after-tax Roth option. Plans that lack a Roth feature cannot legally accept catch-up contributions from affected workers.

The Tax Cost That Arrives With Every Withdrawal

Hitting your savings benchmark is only half the battle. How you withdraw the money in retirement often determines how much you actually get to keep. Traditional 401(k) withdrawals are taxed as ordinary income, and once you cross certain thresholds, they trigger costs that many retirees do not see coming until it is too late.

Medicare’s Income-Related Monthly Adjustment Amount (IRMAA) adds a surcharge to your Part B premiums when income crosses set thresholds. In 2026, the standard Part B premium is $202.90 per month. For single filers, the first IRMAA tier begins at $109,000 of modified adjusted gross income and adds $81.20 per month to the premium (with an additional $14.50 Part D surcharge on top of that). Because of IRMAA’s two-year lookback, a large 401(k) withdrawal you make today will raise your Medicare premiums in 2028. A married couple can easily pay hundreds of extra dollars per year in premiums because of a single withdrawal decision made two years earlier.

Above roughly $34,000 in combined income for a single filer, up to 85% of Social Security benefits can become taxable. A retiree pulling from a traditional 401(k) in the 22% tax bracket who also triggers Social Security taxation and IRMAA can face an effective tax rate on those dollars well above their stated bracket.

The Blind Spot: Out-of-Pocket Healthcare Costs

Conventional retirement targets typically leave out the steep cost of medical care, assuming standard cost-of-living adjustments cover health expenses. Fidelity’s 2025 Retiree Health Care Cost Estimate puts the figure at $172,500 for a single 65-year-old retiring today, a 4% increase from the prior year’s estimate. For a couple, that doubles to $345,000, and neither figure includes long-term nursing care. Building a Health Savings Account (HSA) alongside a workplace retirement account remains the most tax-efficient way to ring-fence money specifically for those costs, thanks to the triple tax advantage: contributions reduce taxable income, growth is tax-free, and qualified medical withdrawals are also tax-free.

Four Actions Worth Taking Now

1. Recalculate your personal benchmark using your actual expected spending in retirement, not a percentage of current income. If your mortgage will be paid off and your children are financially independent, your target may be 20% to 30% lower than the standard guideline. If you have significant ongoing obligations, it may be higher.
2. If you are between 60 and 63, confirm with your plan administrator that you are capturing the full super catch-up contribution of $11,250 this year. Many participants are unaware this provision exists, and the window is only four years wide.
3. If your salary crossed $150,000 last year and you are age 50 or older, verify with your retirement platform that your payroll system is correctly routing catch-up deductions into a Roth account to maintain compliance with current federal guidelines.
4. If your combined retirement income, including Social Security and 401(k) withdrawals, will exceed $109,000 as a single filer or $218,000 as a married couple, speak with a fee-only advisor about a Roth conversion strategy before you retire. IRMAA’s two-year lookback means the planning window closes earlier than most people expect.

Editor’s note: This update refreshes the Vanguard balance figures to the 2026 preliminary report, where the average balance reached $167,970 and the median rose to $44,115. The Fidelity healthcare cost estimate has been updated to $172,500 per individual (and $345,000 per couple) from the 2025 Retiree Health Care Cost Estimate, and new data on record-high 401(k) hardship withdrawals in 2026 has been added.
