Which one should you actually pick?
Interactive Brokers. Serious investors who want the widest market access anywhere and the lowest costs at scale.
Charles Schwab is not the wrong answer for everyone. US investors who want a large institution behind them plus a serious trading platform when they need it. Where it struggles: Investors outside the United States, and anyone wanting a simple app with nothing else attached.
The honest framing is that these two are not interchangeable. Interactive Brokers gives you Real stocks (global) with access to 150+ markets, 33 countries, while Charles Schwab gives you Real stocks + funds across US. If you already know which markets you want to hold, that single line decides it faster than any score.
What each one really costs
On the headline number, Interactive Brokers charges from $0 (IBKR lite) and Charles Schwab charges $0. That is the figure both of them advertise, and it is the least useful one for predicting what you will pay.
Where Interactive Brokers actually charges you:
- IBKR Lite: $0 commission on US stocks and ETFs. IBKR Pro: tiered pricing from a very low per-share rate.
- Currency conversion at close to interbank rates, which is far cheaper than the retail apps and matters if you buy foreign shares.
- Market data subscriptions are charged separately, an unfamiliar concept if you have come from a free app.
- No inactivity fee on most account types since 2021.
Where Charles Schwab actually charges you:
- No commission on US stock and ETF trades.
- No account minimum; fractional share investing is supported for certain holdings.
- thinkorswim is included rather than sold as a separate subscription.
- Regulatory pass-through fees apply on sales, and fund expense ratios apply to funds.
For a portfolio under a few thousand, currency conversion and withdrawal fees will almost always cost you more over a year than the commission difference. Work out how you will fund the account and how often you expect to take money out, then compare on that rather than on the per-trade rate.
Is your money safe with either?
Interactive Brokers is regulated by SEC, FINRA, FCA, +. Charles Schwab is regulated by SEC, FINRA. Both are covered by real regulators, so the question is not whether one is legitimate, but which entity your particular account sits under, because that decides your compensation scheme.
Regulated by the SEC and FINRA in the US, the FCA in the UK and multiple other authorities. US accounts carry SIPC protection to $500,000, including $250,000 for cash; UK accounts fall under FSCS to £85,000. IBKR is publicly listed and holds capital far in excess of requirements.
Regulated by the SEC and FINRA, with SIPC protection on client securities up to $500,000, including $250,000 for cash. Schwab is one of the largest brokerages in the United States with a long operating history. SIPC covers broker failure rather than investment losses.
Worth being clear about what that protection is: compensation schemes cover the broker failing and being unable to return your assets. They do not cover your investments losing value. Nothing here removes market risk.
