401(k) Return by the Numbers
Figures are drawn from this article and reflect 2026 limits plus historical and hypothetical planning estimates, which are not guarantees of future results.
The average 401(k) return most planners use sits around 5% to 8% per year net of fees, and where you land inside that band depends almost entirely on your stock and bond mix, your plan’s costs, and how close you are to retirement.
A realistic long-run 401(k) return is roughly 5% to 8% per year net of fees, depending on your stock and bond allocation. A 60/40 portfolio has historically averaged about 6% to 8% (Vanguard), while an all-stock mix runs higher but swings much harder. After roughly 2.5% to 3% inflation, a 4% to 5% real return is a reasonable planning figure.
What is the average 401(k) rate of return?
The average 401(k) rate of return commonly used for planning is 5% to 8% per year, measured net of fund fees. Vanguard has cited about 6% to 8% annually for a 60/40 stock and bond portfolio. That figure is lower than the roughly 10% nominal long-run return of the S&P 500 because most 401(k) accounts hold bonds and cash alongside stocks.
Two numbers get confused here. The S&P 500 has returned close to 10% per year nominally from 1926 through 2025, but that is a 100% stock index, not a diversified 401(k) that also holds bonds and cash. Your own 401(k) return is not a fixed rate; it is an average of many uneven years, and the mix of funds inside your plan sets your realistic range.
Why “the average” is the wrong number to plan around
The average return is a useful benchmark but a poor forecast for any single year, because 401(k) returns almost never actually land on the average. A portfolio that averages 7% over 30 years may gain 24% one year and lose 18% the next. Planning as if every year returns a smooth 7% overstates certainty and hides real risk.
Mean and median also diverge. Because a handful of very strong years pulls the average up, most calendar years feel worse than the headline number suggests, and the typical year usually sits below the long-run mean. This is why the sequence of returns, not just the average, drives outcomes, a point covered in detail below.
What is a realistic 401(k) return by age?
A realistic 401(k) return by age falls as your allocation shifts from stocks toward bonds along a glide path. Younger investors holding 80% to 90% stocks can reasonably plan for roughly 8% to 9.5% long-run before inflation, while investors near or in retirement holding 40% to 60% stocks plan closer to 5% to 6.5%. The table below maps each stage to an expected range.
| Life stage | Typical stock/bond mix | Expected long-run return (nominal) | Character |
|---|---|---|---|
| 20s and 30s | 80/20 to 90/10 | 8% to 9.5% | Highest growth, largest swings |
| 40s | 70/30 to 80/20 | 7% to 8.5% | Still growth-tilted |
| 50s | 60/40 to 70/30 | 6.5% to 8% | Beginning to de-risk |
| 60s (pre-retirement) | 50/50 to 60/40 | 5.5% to 6.5% | Protecting the balance |
| In retirement | 40/60 to 50/50 | 5% to 6% | Income and stability first |
These ranges are planning estimates, not guarantees, and target-date funds inside most 401(k) plans follow a similar glide path automatically. The 2026 bond environment, with higher yields than the prior decade, makes the forward return on the bond side look better than the 2010s trailing average.
In your 20s and 30s (80% to 90% stocks)
In your 20s and 30s, an 80% to 90% stock allocation supports a long-run planning return near 8% to 9.5% nominal. This is the phase where volatility is a feature, not a bug, because decades of compounding and ongoing contributions absorb the down years. A 40% drop stings, but time and dollar-cost averaging on future paychecks work in your favor.
In your 40s and 50s (60% to 70% stocks)
In your 40s and 50s, a 60% to 70% stock allocation lines up with a roughly 6.5% to 8% long-run return. Balances are larger now, so each percentage point matters more in dollars, and many investors start trimming risk. The account still needs stock exposure to outpace inflation across a retirement that may last 30 years.
In your 60s and in retirement (40% to 60% stocks)
In your 60s and into retirement, a 40% to 60% stock allocation points to about a 5% to 6.5% long-run return. The goal shifts from maximum growth to protecting the balance you spent decades building. Holding some stocks still matters for longevity, but the priority becomes limiting the damage from a bad market right when withdrawals begin.
Nominal vs. real return: what inflation does to your 8%
Nominal return is the raw percentage your 401(k) earns; real return subtracts inflation and is the number that actually determines your future spending power. If a balanced portfolio earns 7% to 8% nominal and inflation runs 2.5% to 3%, your real return is only about 4% to 5%. That real figure, not the headline, is the honest planning number.
Over the long run the S&P 500 has delivered roughly 6.5% to 7% real (after inflation) since 1926. Readers who anchor on 8% and forget inflation overestimate how much their balance will actually buy at retirement.
Real return also shapes tax decisions. Understanding your true after-inflation growth helps you weigh moves such as a Roth conversion strategy, where the timing of taxable income interacts with how fast the account is compounding.
Why sequence-of-returns risk matters more than the average near retirement
Sequence-of-returns risk is the danger that poor returns arrive early in retirement, when you are withdrawing rather than contributing, and it can matter more than the average return itself. Two retirees can earn the identical average over 30 years and end with very different results based purely on the order in which the good and bad years fall.
During accumulation, when you are adding money, the order of returns barely changes the outcome. But once withdrawals begin, a steep loss in the first few years forces you to sell more shares at low prices, permanently shrinking the base that must recover. The same average, arriving in a different order, can move a retirement outcome by years of income.
The danger zone is roughly the five years on either side of your retirement date. This is when a market drop does the most lasting harm, because the account is at its largest and withdrawals are just starting. Many investors respond by holding one to two years of spending in cash or bonds and coordinating withdrawals with tax planning, including required minimum distributions that begin at age 73 (age 75 for those born in 1960 or later).
This is a common blind spot in most “average return” articles: the average tells you almost nothing about survival risk in the decade around retirement. Managing the sequence often protects a plan more than chasing a higher average.
What actually drives your 401(k) return
Five factors drive your 401(k) return: asset allocation, the fund menu your plan offers, fees and expense ratios, how consistently you contribute, and your employer match. Allocation sets the ceiling and floor of your range, but fees and match capture quietly decide how much you keep.
- Asset allocation: The stock and bond split is a major driver, setting both your expected return and your volatility.
- Plan investment menu: A 401(k) can only hold what its lineup offers. Low-cost index funds and a sensible target-date option make a strong plan; an expensive, thin menu drags on results.
- Fees and expense ratios: Costs compound against you. An account paying a 1% expense ratio instead of 0.25% can give up tens of thousands of dollars over 20 years on the same gross return.
- Consistency of contributions: Steady payroll deferrals buy shares in down markets automatically, smoothing your entry price over decades.
- Employer match: A 50% match on your contributions is effectively an instant 50% return on that money before markets do anything, which is why funding at least to the full match is a common first priority.
Fees deserve a close look. Cutting the expense ratio from about 1% to 0.25% means about 0.75% more of the return stays invested each year, and that difference compounds over decades. The drag is invisible on a statement but shows up in the ending balance.
Is a 7% return on your 401(k) good?
Yes, a 7% return on a 401(k) is generally good for a balanced, long-run portfolio, because it sits right in the historically normal 5% to 8% range and comfortably beats inflation. For a diversified 60/40 style account measured over many years, 7% net is a healthy, sustainable result rather than an outlier.
Context matters, though. A 7% year for an aggressive 90% stock investor may be below their long-run average, while for a conservative retiree it may be strong. Many investors weigh their return against their own allocation and a multi-year window, rather than a single hot year.
How much will a 401(k) grow in 20 or 30 years?
A 401(k) grows substantially over 20 to 30 years thanks to compounding, even before new contributions. A single $10,000 balance left invested becomes roughly $38,700 in 20 years and about $76,100 in 30 years at a 7% return. The table shows how the same lump sum compounds at 6%, 7%, and 8%.
| Starting balance | Rate | After 20 years | After 30 years |
|---|---|---|---|
| $10,000 | 6% | about $32,100 | about $57,400 |
| $10,000 | 7% | about $38,700 | about $76,100 |
| $10,000 | 8% | about $46,600 | about $100,600 |
These figures assume a one-time lump sum and no further deposits. Real 401(k) balances grow far faster because you add money every paycheck; in 2026 the employee deferral limit is $24,500. Ongoing contributions plus compounding are what turn modest balances into retirement-sized accounts.
Average 401(k) return vs. average 401(k) balance by age
Average 401(k) return and average 401(k) balance by age answer two different questions that search results often conflate. Return is the annual percentage your investments earn (the 5% to 8% range on this page). Balance by age is a dollar snapshot of what typical savers have accumulated, which depends on contributions and years invested, not just performance.
If you came here to benchmark your rate of return, the ranges above are your answer. If instead you want to know whether your total saved is on track, that is a separate benchmark: see our companion guide on how much you should have in your 401(k) by age, the mechanics of how a 401(k) works, and the current 2026 retirement contribution limits.
Frequently asked questions
These are the questions savers most often ask about 401(k) returns, from what counts as a good year to how far a balance can compound over time. The short answers below summarize the ranges covered above, and each one reflects a diversified, long-run portfolio rather than any single strong or weak market year.
Is a 7% rate of return on a 401(k) good?
Yes, a 7% rate of return on a 401(k) is good for a diversified long-run portfolio. It falls inside the historically typical 5% to 8% range and clears inflation of about 2.5% to 3% with room to spare, leaving a healthy 4% or higher real return. Whether it is strong for you depends on your allocation and the time period you measure.
What is a typical 401(k) rate of return?
A typical 401(k) rate of return used for planning is 5% to 8% per year net of fees. Vanguard has cited about 6% to 8% for a 60/40 stock and bond portfolio. All-stock accounts can average higher, closer to the roughly 10% long-run S&P 500 nominal return, but with much larger year-to-year swings.
What is the average 30-year 401(k) return?
Over a 30-year horizon, a diversified 401(k) has commonly averaged in the 6% to 8% nominal range, depending on the stock and bond mix held across those decades. A more aggressive, stock-heavy account can trend higher, nearer the long-run equity average, while a conservative account lands lower. No single year will match the 30-year average.
How much will a 401(k) grow in 20 years?
A single $10,000 balance grows to roughly $32,000 to $47,000 over 20 years at 6% to 8%, before any new contributions. With steady payroll deferrals added each year (up to the $24,500 employee limit in 2026), a real 401(k) grows far more, because compounding works on both your gains and your ongoing deposits.
How much can my 401(k) grow by retirement?
Your 401(k) balance at retirement depends on your contributions, years invested, employer match, and return. Compounding does the heavy lifting: money invested early has decades to grow at 5% to 8%. Consistent contributions plus a full employer match, left to compound, are what most often carry an account to a retirement-sized balance rather than any single strong market year.
Can I expect double-digit returns from my 401(k)?
Most planners do not count on double-digit returns from a 401(k). Individual years can top 10%, and an all-stock account may average near the S&P 500’s roughly 10% nominal long-run figure, but a diversified account with bonds realistically averages 5% to 8%. Planning around 10%-plus overstates growth and understates the risk of down years.

Your return range is only one lever; how you draw the account down and manage taxes on the way out can matter just as much. Many investors near retirement weigh a partial Roth conversion and run a conversion break-even analysis to coordinate growth, future required distributions, and thresholds such as the net investment income tax.
