Charles Schwab vs Interactive Brokers (2026): Margin Rates, Global Markets, Fees and Which Broker Wins
Choose Charles Schwab if you want an easy, full-service broker with branches, 24/7 phone support, banking (Schwab Bank checking with ATM fee rebates), the thinkorswim platform and simple retirement accounts. Choose Interactive Brokers if you borrow on margin (IBKR's rates are typically far lower than Schwab's posted rates), want to trade international stocks in 150+ markets from one account, earn interest on cash, or trade actively. Both charge $0 on online US stock and ETF trades (IBKR Lite) and are SIPC members.

Rates and fees change often. Verify on each broker's pricing pages.
Where Interactive Brokers wins
1. Margin rates. This is the biggest gap. Schwab's posted margin rates are tiered off a base rate around 10%, so smaller borrowers often pay 10%–12%. IBKR ties rates to a benchmark plus a spread that shrinks as balances grow; many comparisons show IBKR at roughly half Schwab's rate. On a $50,000 margin loan, a 5-percentage-point difference is $2,500 a year.
Margin magnifies losses as well as gains. Read what a margin account is before you borrow.
2. Global investing. IBKR lets you buy shares directly in Tokyo, London, Frankfurt, Toronto, Hong Kong and more than 150 markets, and hold cash in multiple currencies. Schwab users mostly rely on US-listed ADRs.
3. Cash interest. IBKR pays competitive interest on eligible uninvested cash. Schwab's default sweep to Schwab Bank pays much less, though you can manually buy money market funds.
4. Active trading tools. Trader Workstation is one of the most powerful platforms available to retail investors. Our guide on opening an Interactive Brokers account explains Lite vs Pro.
Where Schwab wins
1. Ease of use. Schwab's website and app are simpler. Most investors can find what they need without a learning curve.
2. People. Over 300 branches and 24/7 phone support. For a 401(k) rollover, inheritance or a complicated transfer, that's valuable.
3. Banking. Schwab Bank's high-yield investor checking account reimburses ATM fees worldwide, popular with travelers.
4. thinkorswim. Schwab inherited TD Ameritrade's thinkorswim platform, a favorite among options and chart-focused traders.
5. Funds. Schwab's own low-cost index ETFs and mutual funds are among the cheapest in the industry. Our guide to opening a Schwab account covers setup.

Hidden costs to check
- Cash sweep yield. Leaving $20,000 in cash at a low sweep rate can cost hundreds a year in lost interest.
- Margin rates. Only matter if you borrow, but they matter a lot.
- Transfer fees. If you might switch later, IBKR charges $0 for a full outgoing transfer.
- Broker-assisted trades. Both charge extra for trades placed by phone with a representative.
The bottom line
Interactive Brokers is the cost leader for margin, global stocks, cash interest and active trading. Charles Schwab is the better choice for investors who want simplicity, branches, banking and service. For a basic Roth IRA or taxable account full of index ETFs, both are excellent; pick the one whose platform you find easier to use.
