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.
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.
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.
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.
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 guideI'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 guideMy 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).

$146k/$161k thresholds are 2024 single-filer limits. Married limits are $230k/$240k.
| Income | Priority Order |
|---|---|
| <$50k | Match → Roth (most impactful; both) |
| $50k–$100k | Match → Roth → Max 401k |
| $100k–$146k | Match → Roth → Max 401k |
| $146k–$161k | Match → Traditional IRA or backdoor → Max 401k |
| >$161k | Match → Backdoor Roth → Max 401k → Brokerage |
