Zero-Commission Stock Brokers: Understanding Total Costs


The Zero-Commission Revolution


The rise of Robinhood in 2013 sparked a revolution in stock trading. Today, nearly every major broker offers commission-free trading. But how do they make money, and are there hidden costs?


How "Free" Brokers Make Money


Payment for Order Flow (PFOF)

Brokers may receive compensation for routing orders, depending on market and jurisdiction. Order routing, spreads, execution quality and disclosures vary, so an advertised commission rate is not the total cost.


Interest on Cash

Uninvested cash in your account earns interest for the broker. Some pass a portion to you, others keep it all.


Premium Services

Advanced tools, margin trading, and research reports often require a paid subscription.


Securities Lending

Some brokers lend out your shares to short sellers and keep the revenue.


Top Commission-Free Brokers


1. Interactive Brokers (IBKR Lite)

  • **What to check**: Eligibility for $0 commissions on eligible U.S. stocks and ETFs, plus other product and regulatory charges
  • **Other comparison fields**: Routing, data, account type and regional availability

    • 2. Robinhood

  • **What to check**: Eligible $0 commission products, spread and order-routing disclosures, and country availability
  • **Other comparison fields**: App features, account types and product-specific costs

    • 3. eToro

  • **What to check**: Regional stock commission schedule, currency conversion, withdrawal and product-specific fees
  • **Other comparison fields**: Social features, account tier and country availability

    • Cost Comparison Framework


    A meaningful comparison should use the same instrument, order size, currency, execution time and account type. The following is a framework, not a current quote:


    BrokerCheck advertised commissionCheck spread/executionAdd conversion and regulatory costs
    Any brokerCurrent regional scheduleProvider disclosures and live conditionsAccount/product dependent

    Verdict


    Some brokers advertise $0 commissions for eligible products, but total cost depends on the instrument, spread, execution, conversion, market and account. Compare the current provider schedule rather than relying on a fixed table.
