Decision Framework

Should I Open a Brokerage or Contribute to My 401k First?

Short answer: 401k match first, always. Then Roth IRA. Then finish your 401k. Brokerage is last. Here's the complete order — and when exceptions apply.

The Speedrun Take

This is the most common question beginners ask, and the answer is almost always the same: your employer's 401k match is a 50-100% guaranteed instant return. Nothing can beat that. After the match, the Roth IRA is next because tax-free growth for 30 years is worth more than the flexibility of a taxable brokerage. The brokerage account isn't "wrong" — it's just the last layer.

The One-Sentence Answer

Capture the employer match → max the Roth IRA → max the 401k → then open a brokerage.

If you're not doing step 1, ignore every other account for now.

Why This Order?

Four steps with the math behind each one.

1

401k Up to the Employer Match

What it is: Your employer matches a percentage of your contributions. Common: 50% match on the first 6% of salary.

The math: $5,000 contribution → $2,500 free money → 50% guaranteed instant return. Nothing beats this.

What to do: Contribute exactly enough to get 100% of the match. Not a penny more (yet).

Example: If your employer matches 50% of the first 6% → contribute 6% of salary.

2

Roth IRA ($7,000/year, if income-eligible)

What it is: Individual retirement account funded after-tax. All growth and withdrawals are tax-free.

Why before finishing your 401k: You control this account. Not tied to your employer. More fund options. Tax-free growth is extremely valuable over 30+ years.

Income limit: Phases out above $146k single / $230k married (2024). Above this → go to step 3.

Where: Open at Fidelity (best for beginners). Takes 10 minutes.

Important: Open it now even if you can only contribute $100 — starts the 5-year clock for tax-free withdrawals.

3

Max Your 401k ($23,000/year, 2024)

Once your Roth is maxed: go back and max out the 401k contributions.

$23k in pre-tax contributions = significant tax reduction now. If you're in the 22% bracket, $23k pre-tax saves $5,060 in taxes this year.

Not everyone can max both — that's fine. Prioritize: match → Roth → 401k → brokerage.

4

Open a Taxable Brokerage

Once all tax-advantaged accounts are maxed: use a taxable brokerage for overflow.

No contribution limit. No income restriction. No early withdrawal penalty.

Tax-efficient funds only: broad index ETFs (VTI, VXUS). Avoid high-dividend or bond funds in taxable.

Open your Roth IRA and brokerage in one place

Fidelity supports both accounts, with 0.00% expense ratio funds like FZROX — a fast way to get steps 2 through 4 started.

But What If I Need Flexibility?

"I might need the money before retirement — shouldn't I use a brokerage instead?"

The Roth IRA Answer

Roth contributions (not growth) can be withdrawn anytime, penalty-free. You put in $7,000 → you can take that $7,000 back at any time with no penalty. Only the growth is restricted until 59½. Roth IRA is MORE flexible than most people think.

The Brokerage Answer

Yes, a brokerage has no restrictions. But you're paying taxes on growth every year and at sale. Use brokerage for money you might need in <5 years. For money you won't touch for 5+ years, tax-advantaged wins.

When to Break the Order

I have high-interest debt (>7% APR)

Pay minimums on debt, still get employer match (too good to skip), then pay off high-interest debt before Roth IRA.

Invest vs pay debt guide

I'm self-employed or a freelancer (no 401k match)

Skip step 1. Go directly to: Roth IRA → Solo 401k → SEP IRA → Brokerage.

Side hustle taxes guide

My 401k has terrible fund options (expense ratio >0.5%)

Capture the match (free money), then skip maxing it. Fund Roth IRA + brokerage instead. Bad 401k funds after the match aren't worth it.

I'm over the Roth income limit

Step 2 becomes: Traditional IRA (if deductible) or Backdoor Roth (if income is high and 401k is maxed).
