How Much Does IBKR Pro Cost?
In most cases, the IBKR Pro pricing plan at Interactive Brokers does not include a separate platform, custody, account-minimum, or maintenance charge. For example, IBKR’s desktop, mobile, and web-based trading platforms have
no platform fees, and there are
no recurring account fees such as annual or low-balance charges.
In addition, when some fees do apply, such as market data fees, the cost under IBKR Pro can be the same as it is under IBKR Lite, depending on the subscription. This can also be true for some commissions. Forex and bond trades, for example, generally use the same commission structure under either pricing plan, Pro or Lite.
There are some situations where the IBKR Pro schedule costs more or less than the Lite plan. Trades of U.S.-listed stocks and ETFs, for example, have commissions on the Pro plan, but eligible trades are commission-free on Lite. Here are the exact trading fees:
IBKR Pro – Fixed
$0.005 per share, with a
$1 minimum commission and a
1% maximum of trade value
IBKR Pro – Tiered
| Monthly share volume | Commission |
|---|
| Up to 300,000 | $0.0035 per share |
| 300,001 - 3,000,000 | $0.0020 per share |
| 3,000,001 - 20,000,000 | $0.0015 per share |
| 20,000,001 - 100,000,000 | $0.0010 per share |
| More than 100,000,000 | $0.0005 per share |
The tiered schedule has a minimum commission of
$0.35. The 1% maximum still applies. Regulatory fees are passed on to the client under either the tiered or fixed plan. Under the tiered plan, exchange fees, clearing fees, and pass-through fees are also paid by the customer.
For options, IBKR Pro accounts can use tiered pricing. The trading fee ranges from
$0.15 to $0.65 per contract, depending on monthly contract volume and option premium. Lite customers pay the fixed rate on the first 1,000 U.S. option contracts traded per month, and the IBKR Pro tiered model applies to U.S. options volume above 1,000 contracts per month. In either case, there is a
$1 minimum commission per trade. Futures have a similar pricing structure, although the base rate for many U.S. dollar-denominated futures and futures options is
$0.85 per contract. Under IBKR Pro tiered pricing, that rate can drop as low as
$0.25 per contract for high-volume traders.
IBKR Pro customers can actually begin saving money when they trade on margin. They pay
5.38% for smaller U.S. dollar margin debits, with rates decreasing as low as 4.38% for larger balances. These figures assume U.S.
dollars are borrowed. Other currencies have different rates. Lite customers pay a flat 6.38% for borrowed money.
And for eligible idle cash balances above $10,000, IBKR Pro clients can earn 0% on U.S. dollar cash when the account’s NAV is at least $100,000.
Lite accounts, by comparison, earn -1% under the same conditions. Accounts with a NAV below $100,000 receive a lower blended rate, and no interest is paid on the first $10,000 of idle cash. Most other currencies also have a 1% difference between Lite and Pro.
As shown above, IBKR Pro accounts can come out ahead compared with Lite accounts if the client trades on margin heavily or keeps a large amount of uninvested cash.
