The Bottom Line

Opening a brokerage account takes about 15 minutes at Fidelity, Schwab, or Vanguard — all three are excellent choices with $0 commissions and low-cost index funds. Before you open a taxable account, make sure you’ve maxed out tax-advantaged options first (401(k) match, Roth IRA). The most important decision isn’t which brokerage — it’s starting early and investing consistently in low-cost index funds.
