IBKR commissions guide
This tool compares the two IBKR Pro commission plans for US-listed stocks and ETFs.
The calculator applies published IBKR Pro rates for US stocks and ETFs. Under Tiered pricing, venue fees or rebates cannot be known in advance, so they can be entered as a manual adjustment. The IBKR order preview remains the final reference.
IBKR Pro Tiered
The base rate falls as monthly volume rises. Venue, clearing and regulatory fees or rebates are passed through and depend on routing and liquidity.
How to use the comparison
Enter price, quantity and monthly volume tier. For Tiered pricing, add estimated external costs; use a negative number only when a liquidity rebate is expected.
Calculation limits
The result is a pre-trade estimate. It cannot know the execution venue, partial fills, directed orders, OTC securities, fractional shares, sub-dollar rules or later pricing changes.
Markets and currency
The selected market determines currency, minimums and rules. If a plan is unavailable, the tool disables it.
How to read the result
Fixed is a tariff calculation; Tiered may remain a pre-trade estimate when costs or rebates depend on the execution venue.
