how are stock brokers paid: complete guide

How are stock brokers paid

Understanding how are stock brokers paid helps investors spot costs, conflicts of interest, and the best broker for their goals. This article explains the main compensation methods used by brokers and advisory firms for U.S. equity markets — from per-trade commissions to asset-based fees, spreads, payment-for-order-flow, interest income and embedded product charges — and shows how those costs can affect long-term returns.

Note: this guide focuses on stock-market brokerage (full-service, discount, robo-advisors and RIAs) and related securities (options, mutual funds, ETFs, bonds). It does not cover unrelated uses of "broker."

截至 2026-01-23，据 SEC and FINRA 报道 regulators continue to require clear fee disclosures; investors should check up-to-date broker agreements and fund prospectuses for the latest rates and terms.

Quick takeaway: if you ask "how are stock brokers paid?" the answer is multi-part — some fees are explicit (commissions, AUM fees), others are embedded (spreads, fund expense ratios, 12b-1 fees), and some revenue sources (PFOF, interest) create incentives that matter for execution quality and cost.

Types of brokers and advisors

Different broker types use different compensation models. Knowing which you’re dealing with helps answer how are stock brokers paid in each case.

• Full-service brokers: Provide personalized advice, research, and client service. They commonly combine commissions, AUM/advisory fees, and account/service charges.
• Discount and online brokers: Focus on trade execution and lower costs. Many now offer zero-commission trades for stocks/ETFs but rely on indirect revenue (spreads, payment-for-order-flow, interest) and fees for other products.
• Robo-advisors and digital advisory platforms: Typically charge a percentage of assets under management (AUM) for automated portfolio management; trading costs are often bundled or very low.
• Registered Investment Advisors (RIAs): May charge AUM fees or flat advisory fees and are often held to fiduciary standards; some RIAs also use commission-based arrangements depending on services.

Full-service brokers

Full-service brokers provide research, investment recommendations, and tailored account management. When investors ask "how are stock brokers paid" about full-service firms, the answer often includes a mix of:

• Commissions per trade when brokers execute transactions on behalf of clients.
• AUM/advisory fees for managed accounts or wealth management services.
• Account charges, service fees, and product-level fees (mutual fund loads, 12b-1 fees).

Because full-service brokers deliver advisory time and human guidance, their total cost of service tends to be higher than discount options.

Discount and online brokers

Discount brokers focus on low-cost trade execution. Many firms advertise commission-free trading for U.S. stocks and ETFs, which changes the direct answer to "how are stock brokers paid":

• They may charge zero commissions on many equity and ETF trades.
• They still earn revenue indirectly via payment-for-order-flow (PFOF), interest on uninvested cash, margin interest, and exchange routing rebates.
• Fees remain for certain products (mutual funds, bonds, options trade components) and services (wire transfers, paper statements).

Robo-advisors and registered investment advisors (RIAs)

Robo-advisors and many RIAs typically use asset-based fees:

• AUM fees are expressed as an annual percentage (for example, 0.25%–1.00% of assets) and charged monthly or quarterly.
• Robo platforms may bundle trading and rebalancing costs into that AUM fee and use low-cost ETFs to keep product expenses down.
• Some advisors also charge performance fees or flat subscription fees in special arrangements (see Performance fees below).

When asking "how are stock brokers paid" for automated platforms, the short answer is mostly AUM fees plus the embedded costs inside the funds they use.

Direct transaction-based compensation

Direct transaction fees are visible charges that clients see on trade confirmations or monthly statements.

Commissions (per-trade)

Traditional brokerage commissions are charged each time you buy or sell a security. They may be:

• A flat fee per trade (e.g., $4.95 per trade).
• A per-share fee (e.g., $0.005 per share).

In recent years many online brokers moved to zero-commission stock and ETF trades. Nevertheless, commissions still appear for certain products (some mutual funds, OTC securities) and for trades placed through a human broker rather than online order entry.

Flat fees and per-share pricing

• Flat fees: Simple and predictable for small or larger trades.
• Per-share fees: Scale with trade size; often used historically for small retail trades or certain broker-dealers.

Options trading often uses a combination of a flat base fee plus a per-contract charge. For example: $0.00–$5.00 base + $0.65 per contract (rates vary across firms and over time).

Option and contract fees

Options trades typically incur a per-contract charge, and some brokers charge additional base fees. Bond trades and more complex securities may carry markups or negotiated commissions depending on liquidity.

Asset-based and advisory fees

Many advisory services charge based on assets under management (AUM). This model directly answers "how are stock brokers paid" for managed accounts.

AUM / advisory fees

• AUM fees are quoted as an annual percentage of assets (e.g., 0.25%–1.00% annually).
• They are usually charged pro rata (monthly or quarterly) based on account value.
• AUM fees can cover portfolio construction, rebalancing, reporting, and advisor time.

Robo-advisors frequently charge 0.15%–0.50% AUM. Human RIAs or wealth managers may charge higher rates but offer more personalized advice.

Performance or incentive fees

Some advisors (especially hedge funds and certain wealth managers) charge performance fees — a share of returns above a benchmark. Performance fees can align advisor and client interests but also raise conflicts and are subject to regulatory disclosure requirements.

Indirect or embedded revenue sources

Many brokers earn revenue that is not shown as a line-item "commission." These indirect sources affect the economics of trading and answering "how are stock brokers paid."

Bid-ask spreads and markups/markdowns

• Market makers and dealers earn the spread between bid and ask prices. Retail order execution that crosses the spread effectively pays this cost.
• If a broker executes from inventory or routes to specific liquidity providers, markups/markdowns may apply.

Payment for order flow (PFOF) and order routing

• Payment for order flow is when market makers or wholesalers pay brokers for routing retail orders to them.
• PFOF helps many brokers fund zero-commission trading but creates potential conflicts: a broker might route orders to the highest payer rather than the venue with the best execution quality.
• U.S. regulators require disclosure of PFOF arrangements; execution quality metrics are also reported. Investors should review these disclosures when evaluating how are stock brokers paid at a particular firm.

Interest income (cash sweep and margin)

• Brokers earn interest on uninvested cash via cash-sweep programs (moving client cash into interest-bearing bank accounts or funds). The broker often keeps a portion of the interest spread.
• Margin interest: Clients borrowing to trade pay interest on margin loans; this is a substantial revenue source for many brokerages.

Rebates, routing fees, and exchange/clearing fees

• Exchanges and routing venues may pay rebates for adding liquidity or charge fees for taking liquidity; brokers' routing choices can affect the net cost to investors.
• Clearing and regulatory fees are often passed through to clients as small line items but ultimately affect total cost.

Soft dollars and research credits

• Soft-dollar arrangements let brokers or funds use client commissions to pay for research and other services. These are regulated and must benefit clients, but transparency and potential conflicts are important to monitor.

Product-level embedded fees

Some of the costs that answer "how are stock brokers paid" come from the investment products they sell or recommend.

Mutual fund loads (front-end/back-end) and 12b-1 fees

• Loads: Sales charges on mutual funds (front-end reduces the amount invested; back-end charges on redemption) compensate intermediaries.
• 12b-1 fees: Ongoing annual fees inside a fund for marketing and distribution (commonly 0.25% or more) that pay intermediaries and reduce investor returns.

Expense ratios (mutual funds and ETFs)

• Expense ratios are annual operating costs of funds expressed as a percentage of assets. They directly reduce a fund’s returns.
• Funds with higher expense ratios pass more revenue to fund managers and distributors than low-cost peers. Expense ratios are a major component of the answer to "how are stock brokers paid" when brokers distribute or recommend funds.

Account and service charges

Beyond trading and product costs, brokerage firms may charge various account and service fees. These include:

• Account maintenance or custodial fees.
• Inactivity fees for dormant accounts.
• Wire transfer, ACH or electronic funds transfer fees.
• Paper statement fees and postage.
• Account transfer (ACAT) or account closing fees.
• Minimum-balance or advisory minimum fees for managed accounts.

While each fee may be modest, together they contribute to how are stock brokers paid and can matter for smaller accounts.

Regulatory disclosure and consumer protections

Regulators require firms to disclose compensation arrangements so investors can answer "how are stock brokers paid" for any provider.

Required disclosures (Form CRS, fee schedules, prospectuses)

• Form CRS: Many broker-dealers and RIAs must provide a Client Relationship Summary describing services, fees and conflicts.
• Fee schedules and account agreement documents show explicit transaction and service fees.
• Fund prospectuses list loads, 12b-1 fees, and expense ratios for mutual funds and ETFs.

Investors should review these documents before opening an account or accepting recommendations.

FINRA, SEC and other oversight

• FINRA and the SEC oversee broker conduct and require disclosures about fees and conflicts. BrokerCheck (FINRA) and Investor.gov (SEC) are tools investors use to research broker backgrounds and regulatory actions.
• As of 2026-01-23, regulators continue to emphasize transparency and execution-quality reporting to help investors compare how are stock brokers paid across firms.

Conflicts of interest and transparency issues

Different payment methods create different incentives:

• Commission-based pay can encourage higher trading frequency (churning).
• AUM fees incentivize growth of account balances, which may not always align with low-cost product recommendations.
• PFOF and routing rebates can create incentives to route orders for payment rather than best possible execution.

Disclosure, fiduciary duties (for RIAs), and comparing execution-quality reports help mitigate these concerns.

Impact on investor returns and examples

Fees matter because they compound over time and reduce net returns. A clear answer to "how are stock brokers paid" should include the effect of fees on long-term wealth.

Illustrative example (hypothetical):

• Starting investment: $100,000
• Annual gross return before fees: 7%
• Scenario A (AUM fee 1.00% annually): net return = 6.00%
• Scenario B (AUM fee 0.25% annually): net return = 6.75%
• Scenario C (zero commission trading but fund expense ratios total 0.30%): net return = 6.70%

Using compound growth over 30 years:

• Scenario A (6.00% net): Future value ≈ $574,349
• Scenario B (6.75% net): Future value ≈ $745,984
• Scenario C (6.70% net): Future value ≈ $733,925

Difference between a 1.00% AUM fee and a 0.25% AUM fee over 30 years on $100,000 at 7% gross can be roughly $171,635 in this example. This simple numeric illustration shows why answering "how are stock brokers paid" requires attention to fee structure and long-term compounding.

(Actual outcomes vary with returns, taxes, and fees. All numbers here are illustrative.)

How to evaluate and minimize broker costs

Practical steps to answer "how are stock brokers paid" for any particular firm and to reduce costs:

• Compare commission schedules and AUM/advisory fees across firms.
• Review execution-quality disclosures and PFOF reports to understand trade execution outcomes.
• Favor low-cost index funds and ETFs with competitive expense ratios.
• Avoid mutual funds with front-end/back-end loads and high 12b-1 fees.
• Consolidate accounts where possible to meet advisory minimums and negotiate AUM rates for larger balances.
• Minimize unnecessary trading to reduce per-trade and opportunity costs.
• Consider cash-sweep options and compare the interest paid on uninvested cash.

Special considerations for different investor types

• Active traders: Per-trade costs, option contract fees, and execution speed matter most. Zero-commission stock trades are helpful, but watch spreads, PFOF disclosures, and margin rates.
• Buy-and-hold investors: Expense ratios, mutual fund loads, and AUM fees dominate long-term performance. Low-cost index funds and robo-advisors with low AUM fees often perform well.
• Small accounts: Flat per-trade fees can be costly for small balances. Look for brokers with low or no minimums and low per-trade charges.
• High-net-worth clients: Personalized service from full-service brokers or private wealth teams may justify higher fees, but negotiate AUM rates and confirm value added.

Frequently asked questions

Q: Are there truly commission-free trades?

A: Many brokers offer commission-free trades for U.S. stocks and ETFs. However, "commission-free" does not mean cost-free — indirect revenues (PFOF, spreads, fund fees) still apply and should be evaluated.

Q: How does payment-for-order-flow affect me?

A: PFOF can help fund zero-commission offerings but may create conflicts. Review the broker’s PFOF disclosures and execution-quality reports to assess whether routing practices impact trade prices and fills.

Q: What’s the difference between fee-based and commission-based advisors?

A: Fee-based advisors charge AUM, hourly, or flat fees and may also earn commissions on certain products. Fee-only advisors receive no commissions. Fee-based arrangements require careful review of conflicts and disclosures.

Q: Can I negotiate broker fees?

A: Yes — large accounts often can negotiate lower AUM fees or better margin rates. For retail investors, shop for low-cost brokers and funds.

Q: Where can I find exact fee numbers?

A: Read the broker’s fee schedule, Form CRS, account agreement, and fund prospectuses. Regulatory sites like FINRA and SEC (Investor.gov) also provide educational material about fees.
