Roth IRA vs. 401(k): Which one’s better?

Roth IRAs and 401(k)s have different benefits and drawbacks, and one is offered through an employer while the other is opened individually. So, you’ll have to consider certain factors to determine which is better for you.

When to consider a Roth IRA

A Roth IRA is a good option if you:

  • Want more investment control. Depending on the IRA custodian, invest in anything from stocks and bonds to ETFs, mutual funds and alternative assets like cryptocurrency.
  • Prefer tax-free distributions in retirement. Because you contribute after-tax money, qualified distributions are tax-free. This may be a good option if you think you’ll be in a higher tax bracket when you retire.
  • Don’t want RMDs. Unlike traditional IRAs and 401(k)s, Roth IRAs have no RMDs. Mandatory withdrawals are only required after the death of the account owner(5).
  • Want access to your contributions. Withdraw your Roth IRA contributions at any time tax- and penalty-free.

When to consider a 401(k)

A 401(k) is a good option if you:

  • Have an employer who will match your contributions. Matching contributions is essentially free money you shouldn’t leave on the table.
  • Prefer mutual funds. Mutual funds are the primary investment options for most 401(k)s.
  • Want to reduce your taxable income. 401(k) contributions are made using pre-tax dollars, and every dollar you save will reduce your taxable income by an equal amount.

The similarities between a Roth IRA and a 401(k)

Roth IRAs and 401(k)s don’t have much in common other than allowing you to grow your retirement savings tax-free. Investment options are different, contribution amounts are different and individuals open IRAs while 401(k)s are employer-sponsored.

Roth IRA vs. 401(k): Where to open these accounts

Open a Roth IRA through banks or traditional brokerages, including Fidelity and Charles Schwab, or with stock trading apps like Robinhood and SoFi Invest.

401(k)s are only available through an employer.

Alternatives to a Roth IRA and a 401(k)

While Roth IRAs and 401(k)s are great options to help you save for retirement, keep in mind that there are other ways to save:

  • High-interest savings accounts. Consider a high-yield savings account if you want easy access to cash savings for an emergency fund
  • Health savings accounts (HSAs). An HSA is a tax-advantaged savings account that can help you pay for healthcare expenses. Using an HSA, you can put money away and withdraw it tax-free when you need it for qualified medical expenses. At age 65, you can take penalty-free distributions from the HSA for any reason. However, you still need to use your money for medical expenses to avoid taxes.

    Frequently asked questions

    Is it better to keep money in a 401(k) or Roth IRA?

    When deciding whether to keep money in a traditional 401(k) or a Roth IRA, consider the pros and cons of both. For instance, 401(k) money goes in pre-tax, and your contributions to the account reduce your taxable income. However, you have to pay taxes when you withdraw funds in retirement. With a Roth IRA, you contribute post-tax dollars and don’t get a tax deduction for contributing, but you don’t have to pay taxes on qualified distributions in retirement.

    Is Roth 401(k) better than a traditional IRA?

    A Roth 401(k) isn’t better or worse than a traditional IRA. The two types of accounts are simply different. A Roth 401(k) might be better for you than a traditional IRA if you want to invest easily through payroll deductions and enjoy tax-free withdrawals in retirement. A traditional IRA might be better if you want more control over your investment options and take a tax deduction on your contributions.

    Why is the Roth IRA better?

    A Roth IRA is good if you like to have control over the types of assets you can own in your retirement portfolio. It’s also good if you would rather invest with post-tax dollars and not pay taxes when you take qualified distributions in retirement.

    Is it better to do Roth or pre-tax 401(k)?

    It’s better to save with a Roth 401(k) than a pre-tax 401(k), often called a “traditional” 401(k), if you prefer not to pay taxes on your retirement savings when you withdraw them in retirement. A pre-tax 401(k) is better for those who want to reduce their taxable income in the year they contribute.
