Interactive Brokers and TD Ameritrade are two of the biggest names in the industry. And with so many features in common, the right platform for your portfolio depends entirely on your level of trading experience.

Which one is better?

  • Choose Interactive Brokers if you’re a day trader or professional investor.
  • Choose TD Ameritrade if you’re a new to intermediate investor.

Interactive Brokers and TD Ameritrade are notoriously well-known in the trading industry — and for good reason. They stand as two of the best-equipped, most sophisticated platforms on the market. Naming one of these platforms an unequivocal winner isn’t only tough — it’s complicated. And that’s because when these platforms are put head to head, it becomes starkly evident that Interactive Brokers and TD Ameritrade have a lot to offer — a point further complicated by the fact that many of their available features are the same. Among the common offerings we find a sweeping selection of tradable securities, numerous account options, elaborate charting tools, robust research resources, paper trading, robo-advisors and no less than five unique trading platforms apiece.
With so much in common, where do we draw the line? It comes down to the type of trader each platform is best equipped to serve.
To be fair, TD Ameritrade is more than capable of satisfying the advanced investor. And Interactive Brokers offers IBKR Lite — a platform designed with the beginner investor in mind. But when push comes to shove, Interactive Brokers is the better platform for professional traders, boasting numerous third-party software integrations and wider access to international markets. And TD Ameritrade is more approachable for beginners, with less complex pricing and 24-hour customer support.

Benefits
  • International markets. Investors have access to tradable securities across 140 international markets.
  • ESG scores. While TD Ameritrade offers a limited lineup of ETFs with high ESG scores, Interactive Brokers provides a deep-dive on individual stock performance across each category.
  • Third-party integrations. Outside its impressive lineup of in-house platforms, Interactive Brokers also integrates with a variety of portfolio management, order management, post-trade allocation and compliance software, including trader favorite, DAS Trader.
  • Forex pairs. TD Ameritrade’s 75 forex pairs are nothing to sniff at, but for traders who intend to swap currencies, IB’s 110 forex pairs offer more coverage.
  • 24/7 support. Not many platforms offer round-the-clock support — but TD Ameritrade offers 24-hour live chat assistance for active members.
  • Uncomplicated pricing. With TD Ameritrade, what you see is what you get. Its commission-free stocks and ETFs cost nothing to trade no matter which of its platforms you use.
  • No account minimums. You can open a TD Ameritrade brokerage account with any amount, opening the door for new traders to get started without any capital requirements.
  • No inactivity fee. Investors are free to trade as often or infrequently as they see fit without having to worry about inactivity fees.
Drawbacks
  • Complex fee structure. Interactive Brokers may be a low-cost platform, but its pricing is far from straightforward. Its pricing scheme includes fixed per-share pricing, tiered per-share pricing by monthly trading activity and commission-free trades for IBKR Lite members that trade stocks and ETFs through specific trading portals.
  • Inactivity fee. IBKR Pro traders face inactivity fees of up to $10 monthly if their net liquidation value falls below $10,000 or if they fail to generate at least $10 in trading commissions over the calendar month.
  • Commissions on mutual funds. TD Ameritrade charges a whopping $49.99 on no-load mutual funds — more than triple Interactive Brokers’ fee of $14.95.
  • FINRA disclosures. TD Ameritrade has 191 FINRA disclosures — legal infringements that are assigned by brokerages don’t follow the rules that govern how securities can be marketed and traded. For comparison, Interactive Brokers only has 64 disclosures.
