A discount broker provides reduced commissions on trades. While these rates are relatively inexpensive, discount brokers do not provide other services that full-service brokers typically would, like investment advice, analysis, and retirement planning. Many cost-conscious traders look for brokers with very low fees. This type of broker can also be attractive to more experienced traders who do not need investment advice or analysis. When looking at our top discount brokers, we overweighted the cost categories in our methodology and ensured that trading technology was still an important factor. Here are our top five discount brokers:

  • Interactive Brokers
  • Robinhood

What Do Brokers Charge To Trade?

Brokers can charge a variety of fees depending on the services they offer. Here are some fees you can typically expect at a brokerage:

  • Stock Trade Fee (per trade): Typically between $0.00 and $6.95
  • Stock Trade Fee (per share): Typically between $0.006 and $0.01
  • Broker-Assisted Trade Fee: Typically between $0.00 and $50.00
  • Mutual Fund Trade Fee: Typically between $0.00 and $50.00


Some brokers charge a per-leg fee for options trades, so frequent spread traders might want to look for brokers who only charge a per-contract fee.

Rise of Free Trading

The landscape of the online brokerage industry has changed dramatically over the last few years, most notably with the change in costs for clients. As volatility returned in 2018 many investors retreated to the sidelines. As a result, brokers needed to make their platforms as attractive as possible to bring fearful investors back.

One method for doing so was by reducing commission fees which, in some cases, went as far as making trades completely free. As brokerages reduced costs, it caused a chain reaction. Brokers needed to remain competitive and lower their prices.

While most brokers were simply reducing costs for their clients, others were going a different route by completely eliminating commissions. One of the early pioneers of commission-free trades was Robinhood. Though they charge no commissions for trades, they make money in other ways, including payment for order flow and interest on cash in accounts.

Discount Brokers vs. Full-Service Brokers

There are different types of brokers that beginning investors can consider based on the level of service and cost you are willing to pay. A full-service, or traditional, broker can provide a deeper set of services and products than what a typical discount brokerage would. Full-service brokers can offer their clients financial and retirement planning as well as tax and investment advice. These additional services and features usually come at a steeper price.

If you are looking for a cheaper, more hands-on approach, a discount broker is a better choice. Discount brokers offer low-commission rates on trades and usually have web-based platforms or apps for you to manage your investments. Discount brokers are less expensive, but require you to pay close attention and educate yourself. Luckily, most discount brokers provide educational resources to help you learn to trade and invest.

Pros & Cons of Discount Brokers

Discount brokers can be ideal for those looking to save money, but if you are newer to the investment world and need more hands-on guidance they may not be worth it for you.


  • Lower cost

  • No need to worry about biased investment recommendations

  • Access to basic educational resources to help you do it yourself


  • No advice or guidance

  • Possible hidden fees

  • Less hands-on customer service


Investopedia’s mission is to provide investors with unbiased, comprehensive reviews and ratings of online brokers. Our reviews are the result of six months of evaluating all aspects of an online broker’s platform, including the user experience, the quality of trade executions, the products available on their platforms, costs and fees, security, the mobile experience and customer service. We established a rating scale based on our criteria, collecting over 3,000 data points that we weighed into our star scoring system.

In addition, every broker we surveyed was required to fill out a 320-point survey about all aspects of their platform that we used in our testing. Many of the online brokers we evaluated provided us with in-person demonstrations of their platforms at our offices.

Our team of industry experts, led by Theresa W. Carey, conducted our reviews and developed this best-in-industry methodology for ranking online investing platforms for users at all levels. Click here to read our full methodology.
