Interactive Brokers vs Charles Schwab — which broker is better?

Pros

• US stocks from USD 0.0035 per share on the Tiered plan, minimum USD 0.35 per order and capped at 1% of trade value
• Currency conversion at 0.20 basis points (minimum USD 2) — an order of magnitude cheaper than most European brokers' 0.25%–1.5%
• Roughly 160 market destinations in 36 countries from a single multi-currency account, with 28 settlement currencies
• No inactivity fee since 2021, plus no custody fee and no platform fee
• Trader Workstation offers over 100 order types plus a mature Python/Java/REST API used widely by retail algo traders
• Nasdaq-listed parent (IBKR) with published quarterly financials and around USD 21 billion of equity capital
• Top-tier licences in the US, UK, Ireland, Australia, Singapore and Hong Kong, with per-entity investor compensation disclosed
• Paper trading account mirrors the live platform, including the full API

Cons

• Customer support is the most common complaint: many requests go through the ticket system, and public reviews (e.g. on Trustpilot) often cite slow replies and template answers
• Trader Workstation has a genuinely steep learning curve; the first session is intimidating even for experienced traders
• The fee schedule is complicated: Fixed versus Tiered, pass-through exchange fees, and per-exchange minimums make cost prediction harder than it should be
• Real-time market data is a paid subscription per exchange, so the headline commissions understate the true monthly cost for active traders
• Account opening is longer and more document-heavy than at app-first brokers, and the website navigation is poor
• Spot crypto is only available to US clients via a separate arrangement; EEA clients get futures and exchange-traded products instead

Pros

• USD 0 commission on every online listed US stock and ETF order, with no share cap and no proprietary-fund restrictions
• thinkorswim desktop, web and mobile are included free — full options chains, thinkScript, backtesting and paperMoney simulation
• Options at USD 0.65 per contract, with the fee waived on buy-to-close orders at USD 0.05 or less
• Around 7,700 no-transaction-fee mutual funds in Mutual Fund OneSource, plus USD 0 new-issue Treasuries at auction
• 24/7 phone and chat support backed by close to 400 physical branches — an unusual combination for a discount broker
• SEC/FINRA-regulated with SIPC cover and an affiliated FDIC-insured bank; parent company SCHW is NYSE-listed and reports publicly
• Schwab Global Account gives online access to 12 foreign markets in local currency from the same login

Cons

• No spot cryptocurrency trading — only ETFs, futures and crypto-adjacent equities, which puts Schwab behind Fidelity and well behind Robinhood
• The default uninvested cash sweep pays close to nothing (0.01% at the time of writing); you have to manually move idle cash into a money market fund
• Transaction-fee mutual funds cost up to USD 49.95 per purchase, with a USD 74.95 ceiling for some fund families
• Margin rates sit near the top of the US market — roughly 11.8% below USD 25,000, versus mid-single digits at Robinhood
• Stock Slices fractional investing is limited to S&P 500 constituents, so it will not cover a small-cap or ADR watchlist
• Trading foreign stocks through a broker costs the greater of USD 100 or 0.75% of principal, which makes ad-hoc international orders expensive
• Currency conversion adds a percentage charge on top of the commission: 1% of principal per conversion below USD 100,000 in the Schwab Global Account, tapering to 0.2% from USD 1,000,000 — USD 100 on a USD 10,000 conversion. Except on small orders, the conversion charge is larger than the online commission. Outside the Global Account, Schwab's pricing guide allows a markup of up to 300 basis points (3%) on USD/foreign-currency conversions
