Interactive Brokers vs Schwab is a tie on the everyday trade: IBKR Lite and Schwab both charge $0 to buy a US stock or ETF online.2 The differences come from who each broker was built for. Interactive Brokers adds a per-share Pro plan and pays interest on idle cash above $10,000, while Schwab offers thousands of no-transaction-fee mutual funds and a robo advisor that charges no advisory fee. This guide compares Interactive Brokers and Schwab across trading costs, options, cash, and margin, and what each offers inside an IRA.

What is Interactive Brokers?
Interactive Brokers is a broker built for active traders that sells two pricing plans: IBKR Lite, with $0 commissions on US stocks, and IBKR Pro, which charges by the share in exchange for direct order routing and volume pricing. Pro also pays a higher rate on idle cash. The plan you pick changes most of the costs below.
What is Charles Schwab?
Charles Schwab is a full-service broker that charges $0 online commission on listed stocks and ETFs, sets no account or trade minimums, and sells thousands of mutual funds with no transaction fee through its OneSource list. Schwab also runs Schwab Intelligent Portfolios, a robo advisor with a $5,000 minimum and no advisory fee.
The Charles Schwab review covers Schwab's research, support, and account range.
Interactive Brokers vs Schwab features compared
Each section below opens with the broker that comes out ahead on that feature, and says so plainly when Tweed couldn't confirm one side.
Stock and ETF trading
Neither broker wins on a plain stock trade, because IBKR Lite and Schwab both charge $0 online for US stocks and ETFs. IBKR Pro charges by the share. A trader pays for Pro to get routing control and volume discounts, not a cheaper single trade.
| IBKR Pro US stock pricing | Rate |
|---|---|
| Fixed | $0.005 per share, $1.00 minimum per order, maximum 1% of trade value |
| Tiered, up to 300,000 shares a month | $0.0035 per share |
| Tiered, above 100 million shares a month | $0.0005 per share |
Options trading
Schwab costs slightly less for someone who trades one contract at a time, because both brokers charge $0.65 per contract but Interactive Brokers sets a $1.00 minimum per order.3 On orders of two contracts or more the price is identical. IBKR's rate applies up to 10,000 contracts a month on options priced at $0.10 or more, a ceiling most individual traders never reach.
Mutual funds and managed accounts
Schwab wins for a fund investor or a hands-off investor, because it sells thousands of mutual funds with no transaction fee through OneSource. Schwab also runs Intelligent Portfolios with no advisory fee once you meet the $5,000 minimum.4 Funds outside OneSource cost up to $74.95 per purchase. Interactive Brokers' funds and managed portfolios weren't part of this check.
Cash interest and margin
Interactive Brokers wins on cash, because it's the only one of the two whose rate Tweed could confirm. IBKR pays nothing on the first $10,000 of idle US dollar cash, then 3.380% above that line on IBKR Pro.5 IBKR Lite pays 2.380%, a full point less. In an account worth under $100,000, IBKR scales either rate by net asset value divided by $100,000. Neither broker wins on margin. IBKR prices loans off a benchmark rate in tiers that fall as the balance grows, but neither IBKR's tier table nor Schwab's margin rates could be read for this update.
Transferring an account out
Neither broker wins on transfers out, because neither fee could be confirmed on the broker's own site for this update. Ask each broker about the transfer-out fee before you move. Tweed doesn't list a fee it couldn't check.
Interactive Brokers vs Schwab fees for three kinds of investor
Interactive Brokers vs Schwab fees differ only for certain kinds of use, so the tables below price a year for three investors: a single-contract options trader, an active stock trader, and an investor holding idle cash. Commissions and interest come from each broker's published schedule; returns, fund expense ratios, and pass-through regulatory fees aren't modeled.
An options trader who buys one contract at a time
A single-contract options trader pays $0.35 more per order at Interactive Brokers because of IBKR's $1.00 minimum. The gap disappears at two contracts.
| Orders per year | Contracts per order | Interactive Brokers | Schwab |
|---|---|---|---|
| 100 | 1 | $100 | $65 |
| 250 | 1 | $250 | $162.50 |
| 100 | 5 | $325 | $325 |
An active stock trader on IBKR Pro
An active trader on IBKR Pro Fixed pays by the share, while Schwab and IBKR Lite charge nothing per online trade. Pro is worth its cost only if routing control or volume pricing is worth the commissions to you. The table assumes each trade is large enough in dollar value that the 1% cap never applies.
| Order size on IBKR Pro Fixed | Cost per order | Cost for 250 orders a year |
|---|---|---|
| 100 shares | $1.00 (the minimum) | $250 |
| 500 shares | $2.50 | $625 |
| 1,000 shares | $5.00 | $1,250 |
| Schwab or IBKR Lite, any size | $0 | $0 |
An investor holding idle cash
An investor who parks cash at Interactive Brokers earns interest only on the balance above $10,000. Below $100,000 of net asset value, IBKR reduces the rate in proportion to account size. The table assumes the cash is the whole account, so a $25,000 account earns a quarter of the headline rate. A separate column shows the same cash inside an account worth $100,000 or more. Benchmark-linked rates change, so these figures reflect October 2026 rates only.
| Idle cash balance | IBKR Pro, cash-only account | IBKR Lite, cash-only account | IBKR Pro, account of $100,000+ | Schwab |
|---|---|---|---|---|
| $10,000 | $0 | $0 | $0 | Not confirmed |
| $25,000 | $126.75 | $89.25 | $507 | Not confirmed |
| $50,000 | $676 | $476 | $1,352 | Not confirmed |
| $100,000 | $3,042 | $2,142 | $3,042 | Not confirmed |
Interactive Brokers vs Schwab for a Roth IRA
For a Roth IRA, Tweed could confirm more on Schwab's side than on Interactive Brokers'. Schwab's IRA page lists $0 opening and maintenance fees across traditional, Roth, rollover, inherited, and custodial IRAs. Interactive Brokers offers IRAs too, but IBKR's account types weren't confirmed on its own site for this update. The Interactive Brokers IRA reviewcovers them. Neither broker lists an IRA match.
| Roth IRA | Interactive Brokers | Schwab |
|---|---|---|
| IRA match | None listed | None listed |
| Opening and maintenance fees | Not confirmed | $0 |
| Stock and ETF trades | $0 on IBKR Lite | $0 online |
| Managed Roth | Not part of this check | Intelligent Portfolios, $5,000 minimum, no advisory fee |
| Interest on idle cash | 0% on the first $10,000 under IBKR's published schedule | Not confirmed |
| Fee to close or transfer out | Not confirmed | Not confirmed |
The cash row matters in a Roth. A new Roth funded at the 2026 limit of $7,500 sits below IBKR's $10,000 line, so the Roth's uninvested cash earns nothing under the published schedule. The Schwab IRA review covers Schwab's five account types in full.
Should you choose Interactive Brokers or Schwab?
The choice between Interactive Brokers and Schwab depends on how you use the account. Both brokers charge $0 for the trade most people make. If Fidelity is also on your list, Interactive Brokers vs Fidelitycovers that pairing.
Choose Interactive Brokers if
- You trade in enough volume that IBKR Pro's per-share pricing and order routing are worth paying for
- You keep more than $10,000 in cash in an account worth $100,000 or more and want a published rate on it
Choose Schwab if
- You want mutual funds, or a robo portfolio with no advisory fee from $5,000 up
- You need a rollover, inherited, or custodial IRA at the same broker as your Roth
- You place lots of single-contract options orders, where $0.65 beats a $1.00 minimum
Price your own year before you open an account
The dollar value of a per-share commission or a cash rate depends on how much you trade or hold. Price your year with the three examples above, then run theTweed retirement calculator to see what a few hundred dollars a year in fees or interest compounds to by the time you retire. The best brokerage accounts roundup compares both brokers with other brokers. If Schwab fits, you can open a Charles Schwab account. If Interactive Brokers fits, you can open an Interactive Brokers account through Tweed's referral link.
Frequently asked questions about Interactive Brokers vs Schwab
Can I have a Roth IRA at both Interactive Brokers and Schwab?
Yes, you can hold a Roth IRA at both Interactive Brokers and Schwab, but every IRA you own shares one IRS limit. For 2026 that's $7,500 in total, or $8,600 at 50 and older, split however you like. Money paid in above the limit owes a 6% excise tax for each year it stays uncorrected.
Why can't I withdraw all my money from IBKR?
You usually can't withdraw all your money from IBKR because part of the balance is tied up: trades that haven't settled, a recent deposit still on hold, or cash backing a margin loan or an open position. These limits are standard across brokers. Money inside an IRA follows IRS withdrawal rules on top of that.
What is the downside to Charles Schwab?
The downside to Charles Schwab is the cost of less common services, not everyday trades. Broker-assisted trades add $25 each, and secondary bond trades carry a $10 minimum. Schwab also pays nothing on IRA contributions. A few app-first brokers now pay a match to win savers who contribute every year.
Is Charles Schwab good for day trading?
Yes, Charles Schwab is good for day trading stocks and ETFs on price, since online trades cost $0 and there's no account minimum. Pattern day trader rules apply at Schwab and Interactive Brokers alike, so a small margin account can't trade in and out freely at either. IBKR Pro's per-share plan exists for traders who want routing control.
Is Charles Schwab safe?
Yes, Charles Schwab is safe in the sense that matters if a broker fails, because its brokerage is a SIPC member. SIPC protects up to $500,000 per customer, including $250,000 for cash. SIPC does not cover market losses. The value of what you own can still fall.
Is Interactive Brokers good for beginners?
Yes, Interactive Brokers can suit a beginner who's comfortable with a busier platform, because it sets no account minimums and IBKR Lite charges $0 on US exchange-listed stocks and ETFs. The drawback is cash interest. A starter balance under $10,000 earns no interest there, and the choice between Lite and Pro is one more decision to make up front.
What brokerage is better than Schwab?
No brokerage is better than Schwab for everyone, but a few beat it on specific costs. Fidelity charges $0 to transfer an account out and sells index funds at a 0% expense ratio. Robinhood and Public pay a match on IRA contributions, while Interactive Brokers publishes a rate on idle cash above its threshold.
