How Much Should Someone in Their 20s Put Into a 401(k) vs a Roth?

One of the most common financial questions young professionals ask is: Should I invest in a Traditional 401(k) or a Roth account? The answer depends largely on your current income and tax bracket—but the good news is that starting early matters far more than getting the split perfectly right.

Here’s a practical guide to thinking about the balance between Traditional and Roth retirement savings.

First: Understand the Difference

A Traditional 401(k) lets you contribute pre-tax income. This lowers your taxable income today, but withdrawals in retirement are taxed as ordinary income.

A Roth account (Roth IRA or Roth 401(k)) works the opposite way. You contribute after-tax dollars now, but qualified withdrawals in retirement are completely tax-free—including all the investment growth.

The core decision comes down to a simple question: Are your taxes likely lower now or in retirement?

Income Under ~$50,000: Lean Toward Roth

If you’re early in your career and in the 10–12% tax bracket, Roth contributions are often the best deal.

You’re paying taxes at a relatively low rate today, and locking in tax-free growth for decades.

Suggested mix:
• 70–100% Roth
• 0–30% Traditional

For many people in this range, maxing a Roth IRA while contributing enough to a 401(k) to capture any employer match is a strong strategy.

Income $50,000–$90,000: A Balanced Approach

As income rises into the 12–22% bracket, diversification between account types becomes valuable.

Suggested mix:
• 50–70% Roth
• 30–50% Traditional

This approach gives you both tax-free money and tax-deferred savings, which creates flexibility when you withdraw funds in retirement.

Income $90,000–$160,000: Start Favoring Traditional

Once you move into higher tax brackets (around 22–24%), the tax deduction from Traditional contributions becomes more valuable.

Suggested mix:
• 60–80% Traditional
• 20–40% Roth

Many investors in this range still contribute to a Roth IRA if they’re eligible, but focus more heavily on pre-tax 401(k) contributions.

Income $160,000+: Mostly Traditional

At higher tax brackets (32% and above), maximizing the tax deduction today usually makes the most sense.

Suggested mix:
• 80–100% Traditional
• 0–20% Roth

Higher earners often use strategies like backdoor Roth contributions to maintain some tax-free assets.

Why Having Both Types Matters

In retirement, having both Traditional and Roth accounts allows you to control how much taxable income you generate each year.

For example, you might withdraw:
• $40,000 from a Traditional 401(k)
• $20,000 from a Roth IRA (tax-free)

This flexibility can help reduce taxes, avoid certain Medicare surcharges, and manage Social Security taxation.

The Real Secret: Start Early

While the Traditional vs. Roth decision matters, the most important factor is simply starting early and contributing consistently.

Even modest contributions in your 20s can compound dramatically over time. The difference between starting at 22 versus 32 can easily mean hundreds of thousands of dollars by retirement.

If you’re just getting started, focus on three priorities:

  1. Contribute enough to your 401(k) to get the full employer match.
  2. Build regular contributions to a Roth IRA if you can.
  3. Gradually increase your total retirement savings toward 10–15% of income.


You don’t have to get the strategy perfect—you just have to get started.
