Yes, contributions to a Roth 401(k) and a traditional 401(k) are combined and count towards the same annual elective deferral limit set by the IRS, meaning you can split contributions between them but can't exceed the total, such as the $24,500 limit for under-50s in 2026; however, Roth IRAs have a separate limit, allowing for additional savings, notes Fidelity Investments and Charles Schwab.
Yes, you can contribute to both a traditional 401(k) and a Roth 401(k) in the same year and split your contributions, but the total amount across both accounts (plus any employer contributions) cannot exceed the annual IRS limit, which is $24,500 in 2026 for those under 50, with higher catch-up limits for those 50 and older. It's one combined limit for all your 401(k)s, not separate maximums for each type.
The contribution limits are the same for Roth and traditional versions of 401(k)s and IRAs. One financial strategy, for those who want to maximize their tax-advantaged savings: Open both types of Roth accounts. You can invest up to the combined allowable limits in a Roth 401(k) and a Roth IRA.
The Roth 401(k) contribution limit for 2025 is $23,500 for employee contributions and $70,000 for employee and employer contributions combined. There's also a $7,500 catch-up contribution for those age 50 to 59 and 64 or older, which raises the employee limit to $31,000 for those eligible.
Key Takeaways
Your choice between maxing out a 401(k) or IRA first depends on income level, tax bracket, employer match, and investment goals. Always prioritize enough 401(k) contributions to earn your full employer match—it's free money that compounds over time.
The 4% rule is a retirement guideline: withdraw 4% of your savings in the first year, then adjust that dollar amount for inflation annually, aiming to make your money last 30 years, but it doesn't account for taxes (Roth IRA withdrawals are tax-free, unlike Traditional IRAs) or varying market conditions, so it's a starting point, not a rigid rule, especially for early or very long retirements.
The Roth 401(k) holds the advantage because tax-free growth and withdrawals in retirement mean your savings won't be affected by future tax rates (since you've already been taxed). Both Roth and traditional 401(k) contribution limits are set at $23,500 ($31,000 if you're over the age of 50) for 2025.
A Roth 401(k) doesn't make sense if you expect your tax rate to be lower in retirement than it is now, as you'd prefer the upfront deduction of a Traditional 401(k) for bigger savings, though high earners can always contribute to a Roth 401(k) (unlike Roth IRAs) if their employer offers it, making the choice purely about tax-rate arbitrage between current and future income brackets.
Roth IRA contribution limits for 2026
The Roth IRA contribution limit for 2026 is $7,500 for those under 50, and an additional $1,100 catch up contribution for those 50 and older. Source: "401(k) limit increases to $24,500 for 2026, IRA limit increases to $7,500," Internal Revenue Service, November 13, 2025.
3. You may not get the full benefit, depending on your retirement tax bracket. The nice thing about a Roth 401(k) is that your money is yours to enjoy tax-free later in life. But if your tax bracket ends up being lower in retirement than during your working years, you may not get the full benefit from a Roth 401(k).
It applies to high earners with FICA wages^ over $150,000* in the previous year. The catch-up contribution limit in 2026 is $8,000*, with a “super catch-up” limit of $11,250* if you're age 60–63 and your plan allows it, on top of the standard contribution limit of $24,500* for 2026.
Yes, you can open a Roth IRA even if you already have and contribute to a retirement plan at work, such as a 401(k) or 403(b). Determining how much to contribute to each will depend on your financial goals assuming you fall within Roth IRA income limits.
Having $100k in a 401(k) by age 40 is a solid start, but whether it's "good" depends on your salary and retirement goals, as experts often suggest having 2-3x your salary saved by then; if you earn $50k, you're ahead, but if you earn $80k+, you might need to accelerate savings, aiming for a 15% savings rate (including employer match) for a comfortable retirement.
Dave Ramsey says a 401(k) is a great place to begin retirement savings. Ramsey is clear: A 401(k) is a smart way to approach saving for retirement. “If your employer matches your contributions (and most do), you get an instant 100% return on part of the money you invest in your 401(k),” Ramsey wrote.
Yes, you can live off the interest/returns from $500,000, but it depends heavily on your lifestyle and expenses, with the common 4% rule suggesting about $20,000 annually, which may require a frugal lifestyle, relocation, or significant Social Security income to supplement. With smart investing (e.g., balanced stock/bond mix) and minimal spending, it's feasible for many, but living in a high-cost area or with high expenses would make it difficult.
Only 3.2% of retirees have $1 million in retirement accounts vs. about 2.6% of Americans in general. The average retirement savings for households aged 65-74 is $609,000, while the median is only about $200,000. The number of "401(k) millionaires" in America reached a record of about 497,000 last year.
Yes, Dave Ramsey strongly recommends choosing the Roth 401(k) option over a traditional 401(k) if your employer offers it, prioritizing its tax-free growth and withdrawals for a significantly larger retirement nest egg, though he still emphasizes getting the employer match first and using Roth IRAs to complement savings. He believes the Roth's ability to make all withdrawals tax-free in retirement makes it mathematically superior, allowing your money to go further.
A Roth 401(k) doesn't make sense if you expect your tax rate to be lower in retirement than it is now, as you'd prefer the upfront deduction of a Traditional 401(k) for bigger savings, though high earners can always contribute to a Roth 401(k) (unlike Roth IRAs) if their employer offers it, making the choice purely about tax-rate arbitrage between current and future income brackets.
