Global Access and Product Range
This is where Interactive Brokers has no peer. IBKR provides access to 150+ markets across 33 countries — you can trade stocks in Tokyo, options in Frankfurt, futures in Singapore, and bonds in London, all from one account. No other retail broker offers this breadth.
Fidelity is primarily a US broker. You can access some international stocks through ADRs and a limited international trading feature, but it’s not comparable to IBKR’s global reach. If you want true international diversification beyond US-listed international ETFs, IBKR is the only realistic option.
Margin and Borrowing
IBKR offers the lowest margin rates in the industry — often 1–3 percentage points below competitors. For a $100K margin loan, the difference between IBKR’s rate and Fidelity’s rate can save you $1,000–$3,000 per year. If you use margin regularly, this alone can justify choosing IBKR.
Fidelity’s margin rates are standard for the industry — competitive but not exceptional. For investors who rarely use margin, this isn’t a differentiator.
Platform Experience
IBKR’s Trader Workstation (TWS) is powerful but has a steep learning curve. It’s designed for professionals — customizable layouts, algorithmic order types, real-time risk management, and sophisticated options analytics. The IBKR mobile app and web portal (Client Portal) are more user-friendly but still more complex than Fidelity’s interfaces.
Fidelity’s platforms are designed for a broader audience. Active Trader Pro offers solid charting and tools, while the web and mobile interfaces are clean and intuitive. For everyday investors managing retirement accounts and long-term portfolios, Fidelity’s user experience is significantly better.
Cost Comparison for Active Traders
IBKR Pro’s tiered pricing can be cheaper than Fidelity for high-volume traders. Options commissions start at $0.15/contract for large volumes (vs. Fidelity’s flat $0.65). Futures at $0.25–$0.85 are unavailable at Fidelity entirely. For active traders, IBKR’s cost structure is superior.
For buy-and-hold investors, Fidelity wins: zero-expense-ratio index funds, no commissions on stocks/ETFs, and no account fees. IBKR Lite matches on stock commissions but can’t compete with Fidelity’s proprietary funds.
Key Takeaways
- Interactive Brokers offers global access (150+ markets), the lowest margin rates, and pro-level tools.
- Fidelity is the best all-around US broker — zero-fee funds, excellent research, and superior service.
- IBKR is cheaper for active traders (tiered options/futures pricing); Fidelity is cheaper for passive investors (zero-fee funds).
- Fidelity is more user-friendly; IBKR has a steeper learning curve but more power.
- For most US-focused long-term investors, Fidelity is the better choice. For traders and global investors, IBKR wins.
Frequently Asked Questions
Is Interactive Brokers good for beginners?
IBKR Lite is reasonable for beginners — $0 commissions, fractional shares, and a simplified interface. But the platform is clearly built for experienced traders. Fidelity’s onboarding, education, and interface are better suited for new investors.
What’s the difference between IBKR Lite and IBKR Pro?
IBKR Lite offers $0 commissions on US stocks/ETFs (with payment for order flow) and is designed for casual investors. IBKR Pro uses tiered or fixed pricing with direct market access and better execution quality. Active traders and institutions use Pro; casual investors can stick with Lite.
Can I buy international stocks on Fidelity?
Fidelity offers limited international stock trading in select markets, plus access to ADRs and international ETFs. However, it’s nowhere near IBKR’s 150+ market coverage. For serious international investing, IBKR is the clear choice.
Which has better options pricing?
IBKR Pro’s tiered pricing starts at $0.15/contract for high volumes. Fidelity charges a flat $0.65/contract. For traders executing hundreds of contracts, IBKR is significantly cheaper. For occasional options trades, the difference is minimal.
Does Interactive Brokers offer retirement accounts?
Yes — Traditional IRA, Roth IRA, SEP IRA, and SIMPLE IRA. However, IBKR doesn’t offer HSAs, 529 plans, or Fidelity’s zero-fee index funds. For retirement-specific features, Fidelity has a broader and more cost-effective offering.
