Which online brokers charge no commissions?
7 of the 7 brokers we list charge $0 for online US stock and ETF trades (for example Fidelity Brokerage Account, Charles Schwab Brokerage Account and Interactive Brokers (IBKR Lite and IBKR Pro)). Options, phone-assisted trades, margin loans and transfers can still cost money, so the product pages list those too.
What does a broker pay on cash I have not invested?
It varies a lot. Among the brokers that publish a default rate, Vanguard Brokerage Account was highest at 3.81% (7-day yield) and Public lowest at 0.00%. Money market funds quote a 7-day yield and banks an APY. Rates are variable and each is dated on its product page.
What is payment for order flow?
It means a trading firm pays the broker to send it your orders. It is legal and disclosed in each broker's order-routing report, and it is one reason trading can be free. Each product page says whether the broker reports receiving it.
Is my money safe at an online broker?
SIPC protects up to $500,000 per customer, of which $250,000 can be cash, if a member firm fails (SIPC.org, checked 2026-10-14). It does not protect against investment losses.
Can I open an IRA at an online broker?
Yes. 7 of the 7 brokers we list offer Traditional and Roth IRAs. For 2026 you can put in up to $7,500 across all your IRAs ($8,600 if you are 50 or older). See our IRA roundup for the comparison.
How do you rank these brokers?
Brokers are sorted by our editorial review, which weighs what trading, options and idle cash really cost, how openly the broker says how it is paid, its track record and who can use it. It is not a sort by one fee, and nobody pays for a place in it.
