What Are Online Brokers?

Online brokers are intermediaries that facilitate the buying and selling of securities over the internet. Using an online broker, individual investors can sign up for an account online and start buying or selling quickly.

The shift from in-person to online stock brokers has significantly reduced costs for investors, leading to a rise in no-fee trading and $0 commissions on thousands of mutual funds and ETFs. Many online brokers also offer management services for those who don’t want to manage their own investments. For a hands-off approach to investing with less fees, robo advisors can automate your investing while charging a fraction of the cost of traditional portfolio management.

In addition to buying and selling securities, many online brokers offer investor education, lending services, and banking services.

How Do Online Brokers Work?

Online brokers have access to financial markets (like the NYSE and NASDAQ) where trades are performed. When you choose to buy a security, you place your order and your online broker will match you with a seller of that security.

The trade is then executed and both parties receive a confirmation. Sellers will receive their money automatically and buyers lock in the value of the security purchased (though there’s a “settlement period” of 2-3 days before they own it).

Brokers make sure trades are properly executed and comply with regulations set by the Securities and Exchange Commission (SEC)

How Much Do Online Brokers Charge?

Depending on the services provided, online brokers have several fees and charges:

Trading Fees

Though many brokers offer no-fee trading of stocks and ETFs, there are still many securities that incur trading fees. This is a one-time fee charged for each trade transaction (typically under $10).

Management Fees

A full-service online broker who manages your portfolio will typically charge an assets under management (AUM) fee. This typically ranges from 0.50% to 2% of your total assets.

Account Maintenance (or Inactivity) Fees

Some online brokers will charge an annual maintenance fee on your account (usually under $50). This fee is typically for accounts that drop below a minimum amount.

Brokers that focus on active trading may also charge an “inactivity fee” on accounts that do not trade frequently.

Margin Fees

For investors who borrow money to invest, these “margin” accounts will incur interest charges until paid in full.

Withdrawal Fees

To withdraw funds from an online broker, there may be a one-time withdrawal fee incurred.

How Much Money Do I Need to Start Investing?

Many online brokers have a $0 minimum to open a standard brokerage account and require very little to start investing. You can purchase ETFs for the price of a single share, many starting at under $100.

If the online broker offers “fractional shares”, you can invest for less – sometimes as low as $0.01.

For a retirement account (such as an IRA) many brokerages require a $500 minimum to get started.

How Do Online Brokers Make Money?

From trading and account fees to charging for management services, brokerages have plenty of ways to stay profitable.

Though many online brokers now offer thousands of $0 fee trades, they continue to grow by providing additional services to their customer base.

For example, many brokers now offer banking services, including checking and savings accounts. They use the deposited funds to invest in securities themselves, earning much more interest than they pay their customers.

Many brokers also offer full-service account management, charging upwards of 1% of total assets to manage investments for their customers.

They also act as a lender, offering margin to customers and collecting the interest income.

Are Online Brokers Safe?

Most online brokers carry several types of insurance to protect your assets. The two main types are FDIC insurance (up to $250,000 on cash accounts) and SIPC insurance (up to $500,000 on investment accounts).

FDIC insurance is for cash accounts (i.e. money market, savings, checking) and covers up to $250,000 of cash balance if it were to go missing.

SIPC insurance is similar coverage for investment accounts, covering up to $500,000 in lost or missing securities. If your online broker does NOT have SIPC insurance for your investments, your investments are at risk.

Note: Neither of these types of insurance will protect you from the risk of loss when investing your money into securities.

What Should I Look for In An Online Broker?

We’ve put together a comprehensive list of criteria to look for when choosing an online broker. Evaluate these to find a broker that best fits your investing goals.

Account Fees

When using an online broker, understanding how fees are charged is important to your overall investing strategy.

When looking at the total costs for any online broker, some of the fees to review include:

  • Stock, ETF, and mutual fund trading fees

  • Options and futures contract fees

  • Options per-leg fees

  • Margin interest rates

  • Account minimum or inactivity fees

  • Assets under management fees (for managed accounts)

Most discount online brokers should offer no-fee equity trades, low-cost options contracts ($1 or less), and no per-leg options fees. Unless you choose an active trader platform, most shouldn’t require any account minimum or inactivity fees.

Expense Ratios

When investing in any mutual funds or ETFs, there will be an expense ratio for holding those investments. While most index funds are available for less than 0.25%, mutual funds may have more exorbitant fees (sometimes exceeding 1% of your investment).

For managed accounts, the annual AUM fees may be up to 2% of your total portfolio.

Account Minimums

Depending on the type of investment account you open, there may be a minimum investment amount required. Many online brokers boast $0 minimums for most accounts, but some accounts (like IRAs) may require $500 or more.

When choosing stocks or funds to invest in, make note of the minimum investment required for each security.

Investment Options/Choices

When evaluating your favorite online broker, take a look at their available investment options. Some brokers have a more limited selection of securities to invest in while others have thousands of investment options available.

A few options you may want to have available are:

  • Stocks

  • Bonds

  • Mutual Funds

  • ETFs

  • Options

  • Futures

  • International markets

Investment Account Options

When looking for the right online broker, review which types of accounts are available. Here’s a quick list of account types to consider:

Portfolio Construction

Building the right asset allocation is a critical part of investing. Understanding how your online broker helps build your portfolio (and maintain your asset allocation) is something to consider.

To help stay on track toward your investment goals, look for features like access to pre-defined portfolios and the ability to automatically rebalance.

Tax Strategy

Investing will typically impact your taxes, so understanding how a broker handles tax statements and reporting will save you a headache down the road.

Customer Service and Support

You want to know that your broker is there to provide support. Understanding how customer services works – and when they are available – is very important to your peace of mind.

Look for companies with 24/7 live support, whether over the phone or online via chat. Waiting on an email can feel like years when there is a critical issue with your account.

Mobile Compatibility

We’re in a mobile-first world, so it’s crucial to have access to your investments on your mobile device. Online brokers should have simple access to your accounts via the mobile web (or better yet, through a mobile app).

Account Setup

Signing up for an online broker should be a simple, painless process. Understanding the necessary information to get started and approved for an account is important when researching a potential online broker.

Education and Security

Online education is available through most of the larger online brokers, with some offering extensive libraries to beginner and advanced investors alike.

Regarding security, every broker should carry SIPC insurance (and FDIC insurance for any banking products).

Ease of access

Logging into your investment account and accessing your account tools should be easy. If you want to actively trade, you’ll need a powerful trading platform and mobile app that gives you complete control.

No matter what your investing goals are, your online broker needs to be built with the user in mind.
