Compare Online Brokers and Robo-Advisors for October 2026

An online broker lets you pick and trade investments yourself, usually with no commission on U.S. stocks and ETFs. A robo-advisor picks a diversified portfolio for you, rebalances it automatically and charges a yearly advisory fee, often a fraction of a percent of your balance.

Choose a broker if you want control and are comfortable building a simple portfolio, for example with one or two broad index funds.

Choose a robo-advisor if you want investing to run on autopilot. On a $20,000 balance, a 0.25% advisory fee is $50 a year, on top of the funds' own expense ratios.

Often nothing beyond your first purchase. Many brokers have no account minimum and sell fractional shares, so you can buy a slice of a stock or ETF for as little as a few dollars. Some robo-advisors require a minimum deposit, commonly a few hundred dollars.

Before you invest, make sure you have an emergency fund in savings and are paying down high-interest debt.

Regular automatic deposits, even small ones, build the habit and spread your purchases across market highs and lows.

The fees that matter most are fund expense ratios, which every fund charges yearly, and advisory fees, if you use a robo-advisor or adviser. Over 20 years, a 1% yearly fee can cost about a sixth of your ending balance compared with no fee.

Also check trading commissions on options or mutual funds, fees to transfer your account to another firm, and fees for paper statements or wire transfers.

Broad index funds and ETFs from large providers often have expense ratios under 0.10% a year.

A taxable brokerage account has no contribution limit and no withdrawal restrictions, but you pay tax on dividends and gains. A traditional IRA may give you a tax deduction now, and you pay tax on withdrawals in retirement. A Roth IRA uses after-tax money, and qualified withdrawals in retirement are tax-free.

The IRS sets a yearly contribution limit for IRAs and income limits for contributing to a Roth IRA directly. Check the current figures at irs.gov before you contribute.

Withdrawing IRA earnings before age 59½ usually triggers income tax and a 10% penalty, with some exceptions.

SIPC protects customers of member brokers up to $500,000, including up to $250,000 in cash, if the brokerage firm fails and customer assets are missing. It does not protect against losses when your investments fall in value.

Check a firm's registration on FINRA BrokerCheck and its SIPC membership before you open an account.

Cash that a broker sweeps into partner banks may be covered by FDIC insurance instead. The broker's cash sweep disclosure explains which applies.

For most people, broad index funds are the simpler choice. S&P's SPIVA scorecards have found that most actively managed U.S. large-cap funds trailed the S&P 500 over 10- and 15-year periods, and index funds usually cost less.

Picking individual stocks concentrates your risk in a few companies. Many investors keep stock picks to a small share of their portfolio and hold the rest in diversified funds.
