Maxing out your 401(k) could make you a millionaire. Literally. At the 2026 limit, contributing the maximum for 30 years at a 7% average return grows to more than $2.31M. Here's how to make it happen.
2026 Contribution Limits
Employee Contribution Limit
$24,500
Up from $23,500 in 2025
Total Limit (with employer match)
$72,000
Includes employee + employer contributions
Catch-Up Contributions (Age 50+)
Standard Catch-Up (Age 50+)
+$8,000
Total: $32,500
Super Catch-Up (Age 60-63)
+$11,250
Total: $35,750
The "super catch-up" from SECURE Act 2.0 allows even higher contributions in the years you turn 60 through 63. Starting in 2026, if your prior-year FICA wages from the employer sponsoring the plan exceeded $150,000, catch-up contributions must go into the plan's Roth option.
Use the left and right arrow keys to read each column. The same figures are in the table below.
The limit rises to $32,500 at 50, peaks at $35,750 in the years you turn 60 through 63, and falls back to $32,500 from 64. If your prior-year FICA wages from the plan's employer topped $150,000, the catch-up part must go in as Roth, so only the $24,500 base can be pre-tax.

Employer Match: Free Money
Never Leave Free Money on the Table
If your employer offers a 401(k) match and you don't contribute enough to get the full match, you're literally giving up free money. This is priority #1—before paying extra on debt, before other investments.
Common Employer Match Formulas
- 100% match up to 3%
- Contribute 3% → Get 6% total
- 50% match up to 6%
- Contribute 6% → Get 9% total
- 100% match up to 6%
- Contribute 6% → Get 12% total
- Dollar-for-dollar up to $X
- Flat amount regardless of %
Understanding Vesting
Your contributions are always 100% yours. Employer matches often have a vesting schedule:
| Years of Service | Cliff Vesting | Graded Vesting |
|---|---|---|
| 1 year | 0% | 20% |
| 2 years | 0% | 40% |
| 3 years | 100% | 60% |
| 4 years | 100% | 80% |
| 5+ years | 100% | 100% |
Strategies to Max Out
Calculate your per-paycheck amount
$24,500 ÷ number of paychecks = amount per paycheck. For bi-weekly (26 paychecks): $942 per paycheck. With the age-50 catch-up it is $1,250.
Set up automatic increases to reach this over time if you can't start at the max.
Use the "save your raise" strategy
Every time you get a raise, increase your 401(k) contribution by half that amount. You still see more take-home pay, but your savings grow.
A 4% raise → increase 401(k) by 2% and keep 2%.
Front-load contributions (carefully)
Max out early in the year to get money in the market sooner. But watch out for losing employer match if your company matches per-paycheck.
Check if your employer does "true-up" to catch any missed match.
Automate increases
Most plans let you set automatic annual increases (e.g., +1% per year). Set it and forget it.
If you can't max out now, set auto-escalation to gradually reach the maximum.
Budget backwards
Instead of saving what's left after spending, contribute to 401(k) first and spend what's left.
Pay yourself first. You adapt to living on less faster than you think.
Roth 401(k) vs Traditional 401(k)
Traditional 401(k)
- •Contributions reduce taxable income NOW
- •Pay taxes when you withdraw in retirement
- •Required minimum distributions (RMDs) at 73, or 75 if born in 1960 or later
- •Best if you're in a high tax bracket now
Roth 401(k)
- •Contributions are after-tax (no deduction)
- •Withdrawals are 100% tax-free in retirement
- •No RMDs starting in 2024 (SECURE 2.0)
- •Best if you expect higher taxes in retirement
Which Should You Choose?
Choose Traditional if: You're in the 32%+ tax bracket, expect lower income in retirement, or need the tax deduction now.
Choose Roth if: You're early in your career (lower bracket now), expect higher taxes later, or want tax-free income in retirement.
Consider both: Many experts suggest splitting contributions for tax diversification in retirement.
401(k) or IRA: Which Should You Fund First?
The 401(k), up to the full employer match, always comes first. After that, the classic order is to fund an IRA for its wider investment choice and then return to the 401(k). For most readers over 50 with a good plan and a solid income, the better order is simpler: keep filling the 401(k), because it has far more room, a much larger catch-up, and tax benefits that an IRA often cannot match at higher incomes.
The two accounts do the same job in different ways. A 401(k) is run by your employer: contributions come out of your paycheck, the employer may add a match, and you choose from the plan's menu of funds. An IRA is an account you open yourself at any brokerage, with almost any investment you like, but a much lower limit and income tests that decide whether you can deduct a traditional contribution or make a Roth contribution at all. Both come in traditional (tax deduction now, taxed on withdrawal) and Roth (no deduction, tax-free qualified withdrawals) versions.
| 2026 | 401(k) | IRA |
|---|---|---|
| Base contribution limit | $24,500 | $7,500 |
| Catch-up at 50+ | +$8,000 ($32,500 total) | +$1,100 ($8,600 total) |
| Catch-up at 60 to 63 | +$11,250 ($35,750 total) | Same as 50+ |
| Employer match | Often | None |
| Investment choice | The plan's menu | Almost anything |
| Income limit to contribute | None, for traditional or Roth | Roth phases out at $242,000-$252,000 (married), $153,000-$168,000 (single) |
| Deduction for traditional | Always pre-tax | Phases out at $129,000-$149,000 (married), $81,000-$91,000 (single) if you are covered by a workplace plan |
| RMDs on traditional money | At 73, or 75 if born in 1960 or later; delayed while you still work there unless you own 5%+ | At 73, or 75 if born in 1960 or later, working or not |
| Penalty-free access before 59½ | If you leave the job in or after the year you turn 55 | No age-55 exception |
| Charitable distributions (QCDs) | Not allowed | Up to $111,000 a year from 70½ |

When the classic order still makes sense
Fund the IRA before going past the match in the 401(k) if one of these is true:
- •Your plan is expensive. If the cheapest broad index fund on the menu costs well over 0.5% a year, a low-cost IRA is worth using first.
- •You can contribute to a Roth IRA directly. Married couples with modified AGI under $242,000 can, and a Roth IRA has no required distributions for the owner and flexible access to contributions.
- •A spouse is not working. A married couple filing jointly can fund an IRA for a spouse with no earnings, as long as the working spouse's compensation covers both contributions (IRS). That doubles the household's IRA room to $17,200 if both are 50 or older.
How the answer changes after 50
After 50, the gap between the two accounts widens. The 401(k) catch-up is $8,000; the IRA catch-up is $1,100. A worker who maxes the 401(k) with catch-up can shelter $32,500, more than three times the IRA's $8,600. And by your 50s your income is often above the line where a traditional IRA contribution is deductible for someone covered by a workplace plan, which removes the IRA's main tax benefit. A nondeductible traditional IRA contribution defers tax on growth but adds paperwork and little else.
One new wrinkle: starting in 2026, if your FICA wages from the employer were above $150,000 in the prior year, your 401(k) catch-up must go in as Roth. The base $24,500 can still be pre-tax. That is not a bad outcome for most high earners in their late 50s, who will face required distributions on large pre-tax balances later, but it does mean the catch-up no longer cuts this year's tax bill.
Ages 60 to 63: the 401(k) wins clearly
In the years you turn 60, 61, 62 and 63, SECURE 2.0 replaces the regular catch-up with a larger one of $11,250, for a total of $35,750. The larger catch-up applies to workplace plans only; IRAs stay at $8,600. A married couple who both work and are both in this window can put $71,500 into their 401(k)s in a single year, before any employer money. For someone planning to retire at 63 or 64, these four years are the last and best chance to add to tax-advantaged savings, and worth prioritizing over an IRA.
If your income is too high for a Roth IRA
The usual route is a "backdoor" Roth: a nondeductible traditional IRA contribution converted to Roth. It works cleanly only if you have no other pre-tax IRA money, because the IRS pro-rata rule taxes the conversion in proportion to all your traditional, SEP and SIMPLE IRA balances (reported on Form 8606). Many readers in their 50s and 60s have a large rollover IRA, which makes the backdoor mostly taxable. If your 401(k) accepts roll-ins, moving the rollover IRA into it first can clear the way. Some plans also allow after-tax contributions above the regular limit, up to the $72,000 total, with in-plan Roth conversion, often called a mega backdoor Roth. Ask your plan administrator whether yours does.
Near retirement: leave it in the 401(k) or roll to an IRA?
The same trade-off shows up on the way out. Leaving money in the 401(k) keeps two advantages: if you leave the job in or after the year you turn 55, you can take withdrawals without the 10% early-distribution tax, and if you keep working past 73 at that employer, you can usually delay its RMDs. Rolling to an IRA gives you wider investment choice, one place to consolidate old plans, and access to qualified charitable distributions from 70½, which count toward RMDs without adding to taxable income. Many retirees keep the 401(k) until 59½ and roll over after that. Our guides to Roth vs. traditional IRAs and Roth conversions before RMDs cover what to do with the money once you stop contributing. Our guide to rolling a 401(k) into an IRA covers the rules, the RMD-year trap and company stock.
Choosing Investments
The Simple Approach: Target Date Funds
Pick a fund with your expected retirement year (e.g., "Target 2055"). It automatically:
- ✓Diversifies across stocks and bonds
- ✓Automatically rebalances
- ✓Gets more conservative as you age
This is a perfectly fine choice for most people. Don't overthink it.
DIY Approach: 3-Fund Portfolio
If you want more control (and lower fees), build your own:
- US Total Stock Market Index
- 50-60%
- International Stock Index
- 20-30%
- US Bond Index
- 10-30%
Adjust bond allocation based on age: roughly (age - 10)% in bonds is a common guideline.
Watch Out for High Fees
Some 401(k) plans have terrible, high-fee options. Look for index funds with expense ratios under 0.20%. A 1% fee difference can cost you hundreds of thousands over a career.
Mistakes to Avoid
Not contributing enough to get the full match
Fix: At minimum, always contribute enough to get 100% of your employer match.
Cashing out when changing jobs
Fix: Roll over to new employer's 401(k) or an IRA. Early withdrawal = 10% penalty + taxes.
Being too conservative when young
Fix: With 30+ years until retirement, you can handle stock market volatility. Don't keep everything in bonds.
Never increasing contributions
Fix: Set automatic annual increases. You'll barely notice 1% more per year.
Taking 401(k) loans
Fix: You lose compound growth, and if you leave your job, the loan is due immediately.
Ignoring your investments
Fix: Review annually. Make sure your allocation still matches your goals and risk tolerance.
Savings Priority Order
If you can't max everything, prioritize in this order:
Questions to ask your CPA or adviser
Use this guide to understand the numbers, then take these questions to the professionals who know your whole situation.
- Were my FICA wages from this employer above $150,000 last year, so my catch-up has to go in as Roth? Bring last year's W-2.
- Given the RMDs our pre-tax balances will produce, should my base $24,500 go in as traditional or Roth this year, and what bracket do you expect us to be in after RMDs start?
- In the years I turn 60 through 63, can I afford the full $35,750, and what does it save in tax compared with the regular $32,500?
- After the match, should the next dollar go to the 401(k), a Roth or spousal IRA, a backdoor Roth or an HSA? Does a rollover IRA make a backdoor Roth taxable under the pro-rata rule?
- Does my plan allow after-tax contributions with in-plan Roth conversion, and does it accept roll-ins of IRA money? Bring the plan's summary plan description.
- What do the funds on our plan menu cost, from the annual fee disclosure, and if you would manage the money outside the plan instead, what would you charge and what would we get for it?
Key Takeaways
- ✓The 2026 contribution limit is $24,500 ($32,500 if 50+, $35,750 if 60-63)
- ✓Take the match first. After 50, the 401(k) usually beats the IRA for extra dollars: its catch-up is $8,000 against $1,100, and at 60-63 only the 401(k) gets the larger catch-up
- ✓ALWAYS contribute enough to get your full employer match—it's free money
- ✓Use automatic increases to gradually reach the maximum contribution
- ✓Consider both Traditional and Roth for tax diversification
- ✓Target date funds are a solid, simple choice for most people
- ✓Never cash out when changing jobs—always roll over
