Key Differences Between Fidelity and Interactive Brokers
ETF Selection and Research Tools
Fidelity provides access to 2,000+ ETFs with excellent research tools, while Interactive Brokers offers 13,000+ ETFs with excellent research capabilities. Interactive Brokers offers a wider selection of funds, which is beneficial if you want access to specialized or thematic ETFs alongside your core holdings. Both brokers provide excellent research tools, so you won't sacrifice analytical capabilities with either choice.
Fractional Shares and Minimum Investment
Both Fidelity and Interactive Brokers support fractional share investing, which is excellent news for beginners who want to start small. You can invest as little as $1 in any ETF on either platform, making it easy to build a diversified portfolio regardless of how much capital you have. This eliminates the need to save up hundreds of dollars just to buy a single share of a popular ETF like VOO.
Trading Costs and Fees
Both Fidelity and Interactive Brokers offer commission-free ETF trading, which has become the industry standard among major brokerages. You will not pay any fees to buy or sell ETFs on either platform. The real cost difference comes down to the ETFs themselves — their expense ratios. Both platforms provide access to the lowest-cost ETFs from Vanguard, Schwab, and iShares, so your costs will depend on which funds you choose rather than which broker you use. Neither platform charges account maintenance fees or inactivity fees, and both have $0 minimum deposit requirements.
Mobile Experience and Usability
Both Fidelity and Interactive Brokers offer mobile apps for managing your ETF portfolio on the go. The quality of mobile experience varies considerably between platforms. Fidelity (overall best for beginners) and Interactive Brokers (global etf investors and professionals) approach design differently. If you plan to primarily manage your investments from your phone, testing both apps before committing is wise. For long-term ETF investors who only check their portfolio occasionally, the mobile experience matters less than research tools and fund selection.
