Charles Schwab's revenue comes from four main sources, not from charging you trading commissions

Charles Schwab stopped charging commissions on stock and ETF trades in 2019, but the company still makes substantial money from customer accounts. The revenue flows from interest on cash balances, fees on certain account types, lending against your securities, and payments from market makers who route trades through Schwab's systems. Understanding where Schwab's money comes from helps explain why they can offer commission-free trading and what services cost extra.

The largest revenue source is net interest income. When you hold cash in your Schwab account, the company lends that money out to other customers, businesses, or uses it in their own operations, and keeps the difference between what they pay you and what they earn. If Schwab pays you 0.01% annual interest on your cash balance but earns 2% lending it out, they pocket roughly 1.99% of that balance as profit. Multiply that across millions of accounts and billions in customer cash, and the total becomes substantial.

Key Takeaways

  • Schwab's primary income comes from the interest spread on customer cash balances, not from trading commissions.
  • Margin accounts and options trading generate fees and interest charges that Schwab collects directly from account holders.
  • Market makers pay Schwab for the right to execute trades routed through their systems, a practice called payment for order flow.
  • Schwab earns money by lending out customer securities through stock lending programs, though you may receive a small share of that revenue.

Interest income from cash balances and margin lending

Every dollar sitting in your Schwab account as cash is a potential revenue source. Schwab holds these balances in their own sweep accounts or deposits them into partner banks. The company earns interest on the full amount while paying you a smaller rate. The gap between what Schwab earns and what it pays you is called the net interest margin, and it is the single largest profit driver for the company.

Margin accounts amplify this revenue stream. When you borrow money from Schwab to buy securities, you pay interest on the borrowed amount. Schwab's margin interest rates typically range from 5% to 11% depending on your account balance and the amount borrowed, though these rates change with market conditions. A customer borrowing $50,000 at 8% generates $4,000 in annual interest revenue for Schwab. The company also charges a margin maintenance fee on some account types, though this varies by account structure.

Fees on options trading and account services

While stock and ETF trades are commission-free, options trading carries a per-contract fee. Schwab charges $0.65 per contract for most options trades, meaning a single options order involving 10 contracts costs $6.50. This fee structure is standard across the industry, but it generates meaningful revenue from active options traders. A trader executing 20 options trades per month pays roughly $130 in fees annually.

Certain account types and services also generate fees. Schwab charges annual fees for some retirement accounts, advisory services, and specialized account structures. Schwab Institutional accounts used by financial advisors may include platform fees. International wire transfers, wire transfers out of the account, and some research tools carry explicit charges. These fees are smaller individually but add up across the customer base.

Payment for order flow and market maker arrangements

When you place a trade on Schwab, the order does not automatically go to the stock exchange. Instead, Schwab routes many retail orders to market makers — firms that stand ready to buy or sell securities at quoted prices. These market makers pay Schwab for the right to execute your trade. This payment is called payment for order flow, or PFOF.

The market maker profits by buying from you at a slightly lower price than they sell to others, or vice versa — a difference called the spread. They are willing to pay Schwab for your order flow because the volume is profitable. Schwab does not disclose the exact per-share payments, but industry estimates suggest it ranges from a fraction of a cent to several cents per share depending on the security and order size. On millions of trades per day, this becomes a significant revenue stream.

Schwab publishes quarterly reports on payment for order flow, showing which market makers pay for which order types. This transparency allows you to see that Schwab is routing your trades to firms that pay for the privilege, though Schwab argues this arrangement benefits retail traders by enabling commission-free trading.

Stock lending and securities lending programs

Schwab lends out customer securities to other firms, primarily short sellers who need to borrow shares to execute short sales. When you hold stocks or ETFs in a margin account, Schwab may lend those securities without your explicit permission, though you can opt out. The borrower pays interest on the borrowed securities, and Schwab keeps most of that revenue while paying you a small share or nothing at all, depending on your account type.

Some Schwab account holders receive a portion of stock lending revenue, typically through a rebate or credit to their account. The amount varies based on which securities are lent, how long they are borrowed, and current demand. For most retail investors, stock lending revenue is minimal — often less than $10 per year — but for accounts holding large positions in heavily-shorted stocks, the amount can be more meaningful.

Advisory services and managed accounts

Schwab generates revenue from advisory services beyond basic brokerage. Schwab Intelligent Portfolios, an automated investment service, charges no advisory fee but generates revenue through the interest spread on cash holdings and market maker payments. Schwab Intelligent Portfolios Premium, which includes access to human advisors, charges 0.30% annually on assets under management. Schwab also offers robo-advisor services and financial planning consultations that carry separate fees.

Schwab's acquisition of TD Ameritrade expanded its advisory business. Schwab Advisor Services, which serves independent financial advisors, generates revenue through platform fees, custody fees, and other service charges. These advisory revenue streams are smaller than net interest income but represent a growing part of Schwab's business model.

How Schwab's revenue model affects you

Understanding Schwab's revenue sources explains several features of your account. The company can afford commission-free trading because it makes money from your cash balances and order flow. If you keep large cash balances in your account, Schwab profits more from the interest spread, which is why they offer competitive cash management rates — they want your money. If you trade options or use margin, you pay fees directly.

The payment for order flow model creates a potential conflict of interest: Schwab profits when your trades go to market makers who pay for order flow, even if a different execution venue might offer a slightly better price. Schwab is required to execute trades at prices that are at least as good as the best available price, but the spread between the best bid and ask price is where market makers make their money and where Schwab's incentive lies.

None of this makes Schwab unusual — every major brokerage uses similar revenue models. The transparency around payment for order flow and the elimination of trading commissions represent genuine changes in how the industry operates. Knowing where Schwab makes money helps you understand what services are truly free and which ones carry hidden costs.

Frequently Asked Questions

Does Schwab make money if I don't trade?

Yes. If you hold cash in your account, Schwab earns the interest spread on that balance. If you hold securities in a margin account, Schwab may lend those securities and earn lending revenue. Even inactive accounts generate some revenue for Schwab through these mechanisms.

Why does Schwab pay such low interest on cash balances?

Schwab pays you less interest than it earns because the difference is how the company profits. The rate Schwab offers on cash balances moves with market interest rates, but Schwab always keeps a spread. Higher rates would reduce Schwab's net interest margin and cut into profits.

Can I opt out of payment for order flow?

You cannot opt out of Schwab routing your trades to market makers who pay for order flow. You can choose to route trades to a specific exchange manually, but this is not practical for most retail investors. Schwab is required to execute your trades at prices at least as good as the national best bid and ask.

Do I get paid for stock lending?

Most retail Schwab customers do not receive payment for stock lending. Schwab keeps the lending revenue. Some account types or advisory clients may receive a small rebate, but the amount is typically minimal for standard brokerage accounts.

Is Schwab's business model different from other brokerages?

No. All major brokerages use similar revenue models: net interest income, payment for order flow, advisory fees, and lending revenue. Schwab's scale and customer base are larger, but the underlying economics are the same across the industry.
