Roth IRA vs 401(k): Which Is Better and in What Order?

Short answer: in the Roth IRA vs 401(k) comparison, neither is always better. A 401(k) has a much higher limit ($24,500 in 2026) and often an employer match, while a Roth IRA ($7,500 limit) gives tax-free withdrawals and more investment choices. A common order is to contribute enough to the 401(k) to get the full match, then fund a Roth IRA, then return to the 401(k) for the rest.

Key takeaways

• The 401(k) limit for 2026 is $24,500, and the IRA limit is $7,500. You can use both in the same year.
• An employer match is a part of pay you only receive by contributing, so it usually comes first.
• A Roth IRA is funded with after-tax money and is tax-free in retirement when the rules are met. Income limits apply.
• If your tax rate now equals your rate later, traditional and Roth end in the same place. The choice rests on which rate you expect to be lower.

How do a Roth IRA and a 401(k) compare?

Roth IRA eligibility phases out between $153,000 and $168,000 for single filers and $242,000 and $252,000 for married couples filing jointly in 2026. Above that you may use a Roth 401(k), if your plan offers one, which has no income limit. Check current figures at IRS.gov.

What order can you use them in?

1. Get the full 401(k) match. Contribute at least enough to receive it. If the plan matches 100% up to 4% of pay on a $60,000 salary, that is $2,400 a year of free money.
2. Clear high-interest debt. A card at 20% or more costs more than you are likely to earn. See the debt payoff plan.
3. Fund a Roth IRA up to $7,500 if you are eligible, for the wider choice and low fees.
4. Return to the 401(k) to raise your rate toward its limit.
5. Consider a taxable account once the tax-favoured ones are full.

Some people reverse steps 3 and 4 when their 401(k) has poor, high-fee funds, or when they want the 401(k)'s larger tax deferral. Neither choice is wrong. The point is to get the match, keep fees low and save steadily. See how fund fees add up.

Roth or traditional: how do the taxes work?

A traditional 401(k) contribution lowers your taxable income now, and you pay tax on withdrawals. A Roth contribution gets no deduction now, and qualified withdrawals are tax-free. Take a 22% taxpayer putting $1,000 into a traditional account. It lowers that year's tax by $220, so it costs $780 of take-home pay. The same $780 in a Roth account buys exactly $780 of investments.

They match because the tax rate is the same going in and coming out. If you expect a lower rate in retirement, traditional comes out ahead. If you expect a higher rate, perhaps because you are early in your career, Roth does. Many people split between the two for flexibility, since no one knows future tax rates.

How much could each account grow to?

If you saved the maximum each year for 30 years, with contributions at year end and a steady 7% return, the totals would be:

Few people reach the 401(k) limit, so the realistic gain comes from contributing consistently and capturing the match. Learn the basics in what a 401(k) is and Roth IRA for beginners.
