Where Interactive Brokers shines
IBKR Lite: Interactive Brokers has long been a popular broker for advanced traders, but in 2019 the company launched a second tier of service — IBKR Lite — for more casual investors. With IBKR Lite, you get unlimited free trades of stocks and exchange-traded funds that are listed on U.S. exchanges.
Investment selection: If you're interested in trading other investments, including options, futures, mutual funds, fixed income and more, you can do that on 135 exchanges in 33 countries with a Lite account, but the trading costs will be the same as what IBKR Pro investors pay.
Advanced platform: As the name implies, IBKR Pro is geared toward advanced traders. If that's you, you'll probably like the broker's per-share pricing of $0.005 per share (the minimum is $1), advanced trading platform, unmatched range of tradable securities — including foreign stocks — and ridiculously low margin rates.
Both tiers of service have a $0 account minimum and offer fractional shares of stock. IBKR Lite and IBKR Pro have no account maintenance or inactivity fees.
Where Interactive Brokers falls short
Website ease-of-use: Interactive Brokers provides a great deal of information on its website, but finding and interpreting the information you want isn't always easy. For IBKR Pro customers, the various commission and fee structures can make it hard to quickly identify what your costs will be. Portions of the website are dedicated to institutional, broker and proprietary trading accounts, and that can be confusing.

Interactive Brokers in more detail
Account minimum: 5 out of 5 stars
Interactive Brokers allows you to open an account with no minimum required.
Stock trading costs: 5 out of 5 stars
If you're a casual investor, it’s hard to beat the free trades you'll enjoy with IBKR Lite. But even advanced traders who opt for IBKR Pro will like the low stock and ETF commission structure at Interactive Brokers, which favors frequent, high-volume traders at just $0.005 per share. There’s a $1 minimum trade commission and a maximum of 1% of the total trade value, and exchange and regulatory fees are included.
The broker also offers tiered pricing to lower rates even more. Investors who trade up to 300,000 shares a month can pay $0.0035 per share; tiered rates based on trading volume go as low as $0.0005 per share for clients who trade more than 100 million shares a month. Exchange and regulatory fees are extra on this plan.
Options trades: 4 out of 5 stars
Options trading is offered at competitive pricing, for both Pro and Lite customers, with a $.65 charge per contract and no base, plus discounts for larger volumes. The minimum options trade commission is $1 per order.
Account fees: 5 out of 5 stars
Interactive Brokers charges no annual, account, transfer or closing fees, which is relatively rare among brokers we review.
Number of no-transaction-fee mutual funds: 5 out of 5 stars
The retirement-investor set will be happy with the broker's impressive list of no-transaction-fee mutual funds — over 7,700 in all, above and beyond the vast majority of the broker's competitors.
Tradable securities available: 5 out of 5 stars
Interactive Brokers offers something for everyone here: Advanced traders will love the huge selection of products, from standard offerings of stocks, options and ETFs to precious metals, forex, warrants and futures.
Interactive Brokers also offers fractional shares. The ability to purchase a portion of a company's stock, rather than a full-priced share, makes it easier to invest in companies that have lofty share prices. That, in turn, makes it easier to maintain a diversified portfolio, especially for investors with smaller accounts.
Crypto availability: 5 out of 5 stars
Interactive Brokers introduced cryptocurrency trading in 2021, giving users access to bitcoin, ethereum, litecoin and bitcoin cash. And while the service doesn't offer commission-free trading like some brokers do, the fees are pretty minimal, ranging from 0.12% to 0.18%, depending on monthly volume. There is also a $1.75 minimum per order.
Trading platform: 5 out of 5 stars
The casual traders who find IBKR Lite appealing will find the Client Portal platform adequate for their trading needs. But both IBKR Lite and IBKR Pro traders seeking something more powerful can now enjoy access to Interactive Brokers’ Desktop Trader Workstation, which is considered one of the best trading platforms available for advanced traders.
The platform is fast and includes standard features such as real-time monitoring, alerts, watchlists and a customizable account dashboard. An options strategy lab lets you create and submit both simple and complex multileg options orders and compare up to five options strategies at one time.
Other tools include a volatility lab, advanced charting, heat maps of sector and stock symbol performance, paper trading and a mutual fund replicator, which helps users identify ETFs that replicate the performance of a selected mutual fund but offer lower fees. Interactive Brokers For You notifications offer customized alerts about events that could affect a trader’s investments.
Worth noting: Another broker we review, Zacks Trade, offers its customers access to white-labeled versions of Trader Workstation. Zacks Trade charges higher trade commissions, but offers clients free calls with support reps who are licensed brokers. It's an option worth considering for traders who want the power of Interactive Brokers' trading platforms alongside a bit more personal support.
For investors looking to trade with a conscience, Interactive Brokers offers an Impact Dashboard, free to all users on Trader Workstation, the Client Portal or mobile apps. The dashboard allows investors to select their personal investment criteria from 13 principles (including clean air and water, LGBTQ inclusion and gender equality). Investors can also exclude investments based on 10 categories, such as animal testing, corporate political spending and lobbying and hazardous waste production.
Mobile app: 3 out of 5 stars
The IBKR mobile app, available to both Lite and Pro customers, is Trader Workstation on the go, with advanced trading shortcuts, over 400 data columns, option exercise and spread templates, news, research, charting and scanners. Users can create order presets, which prefill order tickets for fast entry. Presets set up on Trader Workstation are also available from the mobile app. However, the app gets only average ratings from both Android and iOS users.
Research and data: 5 out of 5 stars
Interactive Brokers provides access to a huge selection of research providers and news services, many for free, including Fundamentals Explorer, which offers fundamentals data from Thomson Reuters on over 30,000 companies, plus more than 5,500 analyst ratings, and reports and newswires from 82 companies. Other research providers available to all clients include Zacks Investment Research, Morningstar Equity Ownership, Market Realist, 24/7 Wall Street and Seeking Alpha. Over 100 additional providers are also available by subscription.
Customer support: 4 out of 5 stars
Interactive Brokers offers 24-hour phone, email and chat support, six days a week. However, there are no physical branches, so you won't be able to schedule an in-person meeting, if that's your preference.
While many brokerages are only open to U.S. investors, Interactive Brokers is available to investors in 218 countries and territories. As noted above, Interactive brokers opens the door to investing on 135 exchanges in 33 countries, and lets clients fund and trade accounts in 23 currencies.
Is Interactive Brokers right for you?
Interactive Brokers has always been a great choice for active traders, especially those who can move into the broker's cheaper volume-pricing setup. With the availability of free trades through IBKR Lite, even casual traders might find Interactive Brokers a strong contender. But beginner investors might prefer a broker that offers a bit more hand-holding and educational resources.
How do we review brokers?
NerdWallet’s comprehensive review process evaluates and ranks the largest U.S. brokers by assets under management, along with emerging industry players. Our aim is to provide an independent assessment of providers to help arm you with information to make sound, informed judgements on which ones will best meet your needs. We adhere to strict guidelines for editorial integrity.
We collect data directly from providers through detailed questionnaires, and conduct first-hand testing and observation through provider demonstrations. The questionnaire answers, combined with demonstrations, interviews of personnel at the providers and our specialists’ hands-on research, fuel our proprietary assessment process that scores each provider’s performance across more than 20 factors. The final output produces star ratings from poor (one star) to excellent (five stars). Ratings are rounded to the nearest half-star.
