When I started investing in 2017, I was shocked to discover that buying a single stock could cost me $10 in commissions. Now, in 2026, virtually every major brokerage offers commission-free stock trading, and index fund investing has become accessible to anyone with a few dollars and a smartphone.
This guide will walk you through everything you need to know to start investing with zero commissions—without sacrificing quality or ending up with a questionable brokerage.
Zero commission means you can buy and sell stocks, ETFs, and other securities without paying a per-trade fee. However, it's important to understand what this does and doesn't include:
While trading is free, you still pay indirectly through fund expense ratios—the annual percentage charged by ETFs and mutual funds. A low-cost index fund might have a 0.03% expense ratio, while an actively managed fund could charge 0.80% or more. Over 30 years, that difference compounds into tens of thousands of dollars.
My top recommendation for beginners and experienced investors alike. Fidelity offers commission-free stock/ETF trading, no account minimums, a superb mobile app, and excellent customer service. Their research tools are comprehensive, and they offer a solid lineup of proprietary funds with zero expense ratios.
The king of low-cost investing. Vanguard is purpose-built for long-term, passive index fund investing. If you want to follow the Bogleheads philosophy of buying and holding diversified index funds, Vanguard is often the best choice. The interface is less flashy than some competitors, but the costs are rock-bottom.
Schwab combines zero-commission trading with a wide selection of no-transaction-fee mutual funds. Their customer service is excellent, and they offer free financial planning tools. Schwab's acquisition of TD Ameritrade brought even more resources to their platform.
A solid choice for beginners who want an all-in-one financial hub. SoFi offers commission-free stock, ETF, and crypto trading, plus banking services, student loan refinancing, and personal loans. Their Active Investing and Automated Investing options are both commission-free.
Robinhood pioneered mobile-first, commission-free trading. While its reputation took some hits from the GameStop saga and outages, it remains popular for its simple interface. However, serious investors often outgrow Robinhood due to limited research tools and no mutual fund access.
The best investment for most beginners is a simple, low-cost index fund that tracks the entire stock market. Examples include:
These funds give you instant diversification across thousands of companies, with historically consistent market returns over the long term.
Zero-commission investing has democratized access to the stock market. You no longer need thousands of dollars or Wall Street connections to build wealth through investing. With just a few dollars and a free brokerage account, you can start building your financial future today.
The key is to start. Don't wait for the "perfect" time—historically, the best returns come to those who stay invested consistently, not those who try to time the market. Open an account, buy an index fund, and let compound growth work its magic over decades.
