  • Research tools: Stock screeners, analyst reports, earnings calendars
  • Fractional shares: Invest any dollar amount in expensive stocks
  • Educational resources: Videos, articles, and courses for ongoing learning
  • Mobile app quality: You'll use it daily — it must work well and quickly

Frequently Asked Questions

Is my money safe in a brokerage account?

Your investments are protected by SIPC (Securities Investor Protection Corporation) up to $500,000 per account ($250,000 cash) against broker failure — not investment losses. All recommended brokerages carry additional private insurance beyond SIPC limits. Your investments are also held separately from the broker's own assets.

When do I pay taxes on brokerage investments?

You pay taxes on: (1) dividends when received, (2) capital gains when you sell a position at a profit. Holding over 12 months qualifies for lower long-term capital gains rates (0%, 15%, or 20% depending on income). Short-term gains (held under 12 months) are taxed as ordinary income. You don't pay taxes just for holding — only when you sell.

2026 Broker-by-Broker Breakdown

All major brokerages now charge $0 commission on US stock and ETF trades — commissions are no longer the real differentiator. What actually varies: cash sweep yields on uninvested money, fund expense ratios, and platform tools. Terms verified against provider pages as of August 2026.

Fidelity
Commissions: $0 stocks/ETFs, $0.65/options contract  |  Minimum: $0  |  Best for: Best overall for most investors
Zero-expense-ratio proprietary index funds (FZROX, FZILX), a strong 4.9%+ APY default cash sweep via SPAXX, and 200+ Investor Center branches — a genuinely well-rounded default choice.
Charles Schwab
Commissions: $0 stocks/ETFs, $0.65/options contract  |  Minimum: $0  |  Best for: Active traders and investors who want banking integrated
The thinkorswim platform (inherited from TD Ameritrade) is a genuine strength for active traders; note Schwab's default cash sweep yields far less (often under 0.5%) unless you proactively opt into a higher-yield money market fund.
Vanguard
Commissions: $0 stocks/ETFs, up to $1.00/options contract  |  Minimum: $0  |  Best for: Committed buy-and-hold index investors
The industry benchmark for low-cost index funds (average expense ratio ~0.07%), though its mobile app and web interface trail Fidelity and Schwab in usability.
Robinhood
Commissions: $0 stocks/ETFs/options (Gold: $0 options)  |  Minimum: $0  |  Best for: Mobile-first beginners who want the simplest interface
Robinhood Gold ($5/month) unlocks a 3% IRA contribution match and a competitive cash yield — a genuinely useful upgrade if you're maxing out IRA contributions.
Interactive Brokers
Commissions: $0 (IBKR Lite), low margin rates  |  Minimum: $0  |  Best for: Global and advanced traders wanting access to international markets
The only major broker offering true access to 170+ global markets beyond US-listed ADRs, with the industry's lowest margin rates.

What Actually Matters Now That Commissions Are Zero

  • Interest on uninvested cash — on a $50,000 account, the gap between a strong sweep yield (Fidelity's ~4.9%) and a weak one (Schwab's default ~0.45%) can be roughly $2,000/year — a meaningful, often-overlooked difference.
  • Fund expense ratios — Fidelity's ZERO funds charge 0% expense ratio; Vanguard's VOO charges 0.03% — small differences that compound significantly over decades on a large portfolio.
  • Account types supported — not every broker supports SEP-IRAs, trust accounts, or 529 plans — worth checking against your specific needs before committing.

It's OK to Use More Than One Broker

Many experienced investors intentionally split accounts across brokers — using one for core long-term index holdings where fund selection and expense ratios matter most, and another for active trading where platform tools and options pricing matter more. There's no requirement to consolidate everything into a single broker if your needs genuinely span both use cases.
