Interactive Brokers is a NASDAQ-listed brokerage (ticker: IBKR) regulated by 10 Tier 1 authorities including the SEC, FCA, and ASIC. It is widely regarded as the lowest-cost broker for direct market access to stocks, options, futures, forex, bonds, and ETFs across 150+ exchanges in 34 countries. Unlike retail forex brokers that embed all costs in the spread, IBKR passes through interbank/exchange pricing and charges a separate, transparent commission — resulting in total trading costs that are consistently among the lowest in the industry.

This guide breaks down every IBKR fee by asset class — stock and ETF commissions (including the IBKR Lite vs. Pro difference), options and futures pricing, forex spreads and commissions, and the non-trading costs that catch new users off guard (especially market data fees). We explain Fixed vs. Tiered pricing, show you what real trades actually cost in dollars, and identify which pricing model saves you the most based on your trading style.

IBKR Fee Summary

Here is every fee Interactive Brokers charges across all major asset classes. This table uses IBKR Pro Fixed pricing as the baseline; Tiered pricing and IBKR Lite differences are detailed in the sections below.

Stock & ETF Commissions

Interactive Brokers offers three pricing options for US stocks and ETFs: IBKR Lite (US residents only, $0 commissions), IBKR Pro Fixed (flat per-share rate), and IBKR Pro Tiered (volume-based rates with exchange rebates). Choosing the right one depends on where you live and how you trade.

IBKR Lite vs. IBKR Pro

*Tiered rate shown is for the first 300,000 shares/month. Rates decrease with higher monthly volume: $0.0020/share at 300K–3M shares, $0.0015 at 3M–20M, down to $0.0005 at 100M+.

Fixed vs. Tiered: Which Should You Choose?

For most retail traders, Tiered pricing is cheaper. Here’s why: the Fixed rate of $0.005/share is an all-inclusive rate that covers exchange, clearing, and regulatory fees. Tiered starts at $0.0035/share but adds exchange and clearing fees on top — however, those external fees are small (often $0.0002–$0.0003/share), and on many exchanges you receive a rebate for adding liquidity with limit orders. The net result: Tiered usually costs less than Fixed for limit-order traders.

Choose Fixed if: you want one predictable rate with no surprises. You trade small positions where the $1 minimum per order matters less. You use mostly market orders (no rebate advantage).

Choose Tiered if: you use limit orders (to earn exchange rebates). You trade higher volume (rates decrease with monthly share count). You want the absolute lowest possible cost per trade.

European and International Stocks

IBKR provides direct market access to 90+ stock exchanges worldwide. Commissions vary by exchange but are consistently low:

Options & Futures Fees

IBKR is widely considered the best-value broker for options and futures trading — combining low per-contract fees with direct exchange access and sophisticated execution tools.

US Options

On the Tiered model, IBKR SmartRouting can earn you exchange rebates when you add liquidity with limit orders. Active options traders using limit orders frequently pay less than $0.65/contract — and in some cases, the rebate exceeds the commission, resulting in a net credit (you get paid to trade). This is unique among retail brokers.

US Futures

Micro futures (E-micro S&P 500, Micro Crude Oil, Micro Gold) are available at reduced rates — useful for traders who want futures exposure with smaller position sizes and lower margin requirements.

Forex Spreads & Commissions

IBKR’s forex model is fundamentally different from retail forex brokers. Instead of marking up the spread and calling it “commission-free,” IBKR passes through raw interbank pricing from 17 of the world’s largest FX dealers and charges a separate, transparent commission. The result: spreads as tight as 0.1 pips on EUR/USD with a small commission on top — total costs significantly below what most retail brokers charge.

Forex Commission Tiers

1 basis point = 0.0001. On a standard lot (100,000 units) of EUR/USD, the Tier 1 commission is: 0.20 bps × $100,000 = $2.00. This is the minimum, so most retail forex trades cost exactly $2.00 in commission.

Forex Spreads

Because IBKR passes through raw interbank quotes without markup, spreads on major pairs are dramatically tighter than retail forex brokers:

IBKR spreads are variable and reflect real-time interbank market conditions. Industry averages sourced from CompareForexBrokers standard account benchmark (May 2026).

Total Cost Per Trade

Here’s what real trades actually cost on IBKR Pro. These examples use Fixed pricing for simplicity; Tiered pricing is often cheaper.

*Commission-free US brokers like Robinhood use payment for order flow (PFOF) — they sell your order to market makers instead of routing to exchanges. This can result in slightly worse execution prices. IBKR Pro uses SmartRouting for best execution, which can save more than the commission cost on larger orders.

Where IBKR Is Cheapest

Forex: the largest cost advantage. At ~$3/lot vs. $8–$11 at retail brokers, IBKR saves active forex traders 60–70% per trade. A trader doing 50 lots/month saves $250–$400/month compared to Exness Standard or AvaTrade.

Options (Tiered): exchange rebates for adding liquidity can reduce effective costs below $0.65/contract, sometimes to near-zero. No other retail broker offers this.

International stocks: IBKR’s currency conversion at 2 basis points and competitive per-trade commissions make it the cheapest way to build a global stock portfolio. Most banks and traditional brokers charge 0.5–1.5% for currency conversion alone.

Where IBKR Is Not the Cheapest

Small US stock trades: the $1 minimum per order means buying $200 worth of stock costs 0.5% in commission. Commission-free brokers (IBKR Lite, Robinhood, Schwab) are cheaper for small, casual US stock purchases — though you trade execution quality for zero commissions.

Very small forex trades: the $2 minimum commission on forex means a micro lot ($1,000) trade costs 0.20% in commission alone. IBKR’s forex pricing makes sense from mini lots ($10,000) upward.

Non-Trading Fees

Inactivity Fee

IBKR charges no inactivity fee. This was eliminated in July 2021. Your account can sit dormant for months or years without any charges. Compare this to AvaTrade ($50/quarter after 3 months) or many traditional brokers that still charge $10–$20/month for inactive accounts. IBKR earns its money from trading commissions and margin interest — not from penalizing dormant accounts.

Market Data Fees

This is the non-trading cost that catches new IBKR users. Basic non-consolidated US stock data is free for all clients. However, if you want consolidated real-time data, Level II market depth, or data for specific exchanges, you need paid subscriptions.

Practical advice: start with the free basic US data. It covers real-time streaming quotes from primary exchanges and is sufficient for most retail traders. Only subscribe to additional data packages if you specifically need consolidated feeds or international exchange data. Many traders pay for market data they never actually use.

Currency Conversion

IBKR charges 0.002% (2 basis points) with a $2 minimum for manual currency conversions. This is extraordinarily cheap — converting $10,000 from USD to EUR costs $0.20 (rounded up to the $2 minimum). For comparison, most banks charge 0.5–1.5%, and retail forex brokers like AvaTrade charge 0.5%.

However, automatic currency conversions (when IBKR settles trades in foreign currencies on your behalf) use a different rate: approximately 0.03% added to the exchange rate. While still cheap by industry standards, this is 15x the manual rate. If you trade international stocks regularly, convert currency manually in the forex section before placing stock orders.

Deposit and Withdrawal Fees

IBKR charges zero fees on deposits. For withdrawals, one per month is free; additional withdrawals cost $10 per wire transfer. For most traders, one withdrawal per month is sufficient.

How to Reduce Your Trading Costs on IBKR

IBKR’s fees are already among the lowest in the industry, but the right choices can reduce them further. Here are six ways to minimize what you pay.

1. Use Tiered pricing with limit orders. Tiered commissions are lower than Fixed for most retail traders, and limit orders earn exchange rebates that further reduce your effective cost. On some exchanges, the rebate can exceed the commission — making the trade effectively free or even earning you a credit.
2. Convert currency manually, not automatically. Manual forex conversion costs 0.002% (2 basis points). Automatic conversion when settling foreign stock trades costs approximately 0.03% (3 basis points). The manual approach is 15x cheaper and takes 30 seconds.
3. Skip unnecessary market data subscriptions. The free basic US data is sufficient for most traders. Don’t subscribe to Level II or international exchange data unless you actively use it. Review your subscriptions quarterly in Client Portal → Settings → Market Data Subscriptions.
4. Consolidate your withdrawals. One withdrawal per month is free. Plan your withdrawals to stay within the free tier. If you need frequent access to cash, withdraw a larger amount once rather than several smaller amounts.
5. Earn interest on uninvested cash. IBKR Pro pays benchmark − 0.5% on USD cash balances. At current rates, that’s over 3% APY on idle cash. Don’t leave uninvested cash in a bank account earning 0% when it could be earning interest in your IBKR account.
6. Use IBKR’s Stock Yield Enhancement Program. If you hold stocks, IBKR can lend your shares to short sellers and split the lending income 50/50 with you. It’s passive income on shares you already own. Enable it in Client Portal → Settings → Account Settings.

Conclusion

Interactive Brokers’ fees are built for serious traders and investors. The cost structure rewards activity across multiple asset classes: forex at ~$3/lot (60–70% below retail brokers), US stocks from $0.35/trade on Tiered pricing, options with potential exchange rebates, and currency conversion at 2 basis points. Combined with zero inactivity fees, zero account maintenance, and the highest interest paid on cash among major brokers, IBKR’s total cost of ownership is consistently ranked among the lowest in the industry.

IBKR is most cost-effective for traders who execute at least $5,000+ per trade, trade across multiple asset classes or international exchanges, and are comfortable managing a more complex platform. Where IBKR is less cost-effective: very small trades (the $1–$2 minimums per order create a higher percentage cost on small positions), and US-only casual stock investors (IBKR Lite or competing zero-commission brokers are cheaper if execution quality isn’t a priority).
