How Charles Schwab Makes Money

Direct answer: Charles Schwab generates revenue primarily through net interest income (the largest segment, earned on client cash held in bank and sweep accounts), asset management and administration fees on its investment products and advisory services, trading revenue from options commissions and other transaction fees, and bank lending. After acquiring TD Ameritrade in 2020, Schwab became one of the largest retail broker-custodians by assets.

Schwab as a bank-brokerage hybrid

Charles Schwab is often categorized as a brokerage, but its revenue model is more accurately described as a bank-brokerage hybrid. The largest revenue segment is net interest income, which is a banking concept: it represents the difference between the yield Schwab earns on interest-bearing assets and the cost of the liabilities (deposits and borrowings) funding those assets. This model is fundamentally different from Robinhood's PFOF-led model or Fidelity's fund management model, even though all three are brokerage competitors.

The bank is Schwab Bank, a federally chartered savings bank and wholly-owned subsidiary of The Charles Schwab Corporation. Client cash from brokerage accounts is swept into Schwab Bank deposits. Schwab Bank invests those deposits in a portfolio of interest-earning assets: short-duration fixed income securities, residential mortgages, and other loans. The spread between the yield on those assets and the rate paid on deposits is net interest income. At scale, with hundreds of billions of dollars in client cash, even a modest spread generates substantial revenue.

Schwab is a public company listed on the NYSE (ticker: SCHW), which means its financial statements, including the detailed revenue breakdown by segment, are publicly available in SEC filings. This makes Schwab one of the most transparent companies in the brokerage industry from a revenue perspective. Anyone who wants to understand the current revenue mix in detail can read Schwab's most recent annual report or quarterly earnings supplement.

Net interest income: the primary driver

Net interest revenue is consistently the largest single segment in Schwab's reported financials. In peak rate years such as 2023, it has represented approximately 50-60% of total net revenues. In near-zero rate years like 2020 and 2021, this share compressed significantly, and Schwab's overall profitability declined correspondingly.

The mechanics are straightforward. Client cash swept from brokerage accounts into Schwab Bank earns Schwab a spread. If short-term rates are 5% and Schwab pays depositors 0.5%, the gross spread before expenses is 4.5%. On $200 billion of client cash, that is a very large number. Schwab also earns net interest income on margin loans extended to clients and on its portfolio of securities held at the bank level.

The interest rate environment is therefore the most important single variable in Schwab's earnings model. When the Federal Reserve raises rates, Schwab's net interest income rises. When rates fall, net interest income falls. The 2022-2023 rate cycle was historically beneficial for Schwab's net interest revenue; the subsequent rate-cutting cycle from late 2023 onward has reduced it.

This sensitivity creates an unusual situation: Schwab's earnings are substantially higher in a high-rate environment than in a low-rate one, even if nothing else about its business changes. Investors in SCHW stock are, in effect, taking a long position on short-term interest rates through the brokerage model. This is spelled out clearly in Schwab's SEC filings under its risk factors.

The controversy around Schwab's cash sweep rates (discussed in the FAQ below) is directly related to this model. The spread Schwab earns on client cash is larger when Schwab pays depositors less. The default sweep rate at Schwab Bank has historically been substantially below prevailing money market rates, which is how Schwab maximizes net interest income but also how it creates the tension with customers seeking competitive returns on idle cash.

Asset management and administration fees

Schwab's second major revenue segment is asset management and administration fees. This includes management fees earned on Schwab's proprietary ETFs and mutual funds, fees from advisory and managed account programs, and certain fund platform fees.

Schwab is a significant ETF provider. The Schwab ETF family spans U.S. equity (SCHB, SCHX, SCHG), international equity (SCHF, SCHI), fixed income (SCHZ, SCHP), sector, and other exposures. These funds carry low expense ratios, competing with Vanguard and iShares on cost. Schwab earns the management fee on assets invested in these ETFs across all platforms, not just Schwab accounts.

Schwab's managed account and advisory programs include Schwab Intelligent Portfolios (a robo-advisor that charges no direct advisory fee but invests in Schwab ETFs and maintains a cash allocation swept to Schwab Bank), Schwab Intelligent Portfolios Premium (charges an advisory fee on top of the portfolio), and Schwab Managed Portfolios (separately managed accounts run by professional managers). The fee structures vary: some charge a percentage of assets, others charge a flat fee, and the robo product generates revenue indirectly through fund management fees and cash sweep economics.

Mutual fund and ETF marketplace fees, charged for certain funds purchased through the Schwab OneSource platform, also fall into this segment. Schwab acts as a fund supermarket, distributing third-party funds alongside its own, and charges fund companies for that distribution access.

Trading revenue

Schwab eliminated stock and ETF trading commissions in October 2019, prompting TD Ameritrade, E*TRADE, and others to follow within days. This removed the most visible trading revenue from the model. Trading revenue now comes from options commissions ($0.65 per contract as of 2026), futures commissions, forex spread income, and transaction fees on certain mutual fund trades.

Options trading is the most significant remaining source of trading revenue. Schwab and TD Ameritrade (now integrated into Schwab) had a large combined options-active customer base. The thinkorswim platform, acquired with TD Ameritrade, is particularly popular with active options traders, and these customers generate disproportionate options commission revenue relative to their account count.

Trading revenue represents a smaller share of total net revenues than either net interest income or asset management and administration fees. At the scale of the combined Schwab-TDA entity, options commissions are still a meaningful number in absolute terms, but as a percentage of total revenue, trading is a secondary contributor in the current business mix.

The TD Ameritrade acquisition

Schwab acquired TD Ameritrade in October 2020 for approximately $22 billion in an all-stock transaction. At the time of announcement (November 2019), it was one of the largest financial services mergers in recent history. The acquisition gave Schwab approximately 12 million additional accounts, roughly $1 trillion in additional client assets, the thinkorswim active trading platform, TD Ameritrade's institutional advisor custody business (TD Ameritrade Institutional, now Schwab Advisor Services), and TD Ameritrade's physical branch locations.

The integration was a multi-year process. Customer accounts migrated from TD Ameritrade's systems to Schwab's platform in waves through 2023. Some thinkorswim features were preserved as a platform within the Schwab ecosystem, recognizing that the TD Ameritrade active trading customer base would not simply accept a less capable platform.

The revenue impact of the acquisition is substantial across every segment. More client cash means more net interest income. More assets under custody means more fund and advisory fees. More options-active accounts means more trading revenue. The combined entity is materially larger than either predecessor, and the incremental revenue from the combined asset base compounds across all revenue streams simultaneously.

Schwab Advisor Services and institutional custody

Schwab Advisor Services provides custody, technology, and support services to independent registered investment advisers. It is the largest institutional custodian for RIAs by assets in the U.S. following the TD Ameritrade integration. Revenue from the institutional segment comes from the same sources as the retail brokerage, but at institutional scale: net interest income on custodied cash, fund management fees on Schwab products used in advisor portfolios, transaction fees, and securities lending.

The institutional custody business is strategically important beyond its direct revenue contribution. Advisers who custody client assets with Schwab are deeply integrated into Schwab's technology platform, creating high switching costs. Those custodied relationships also include wealthy individual client accounts that may eventually become direct Schwab wealth management customers if the adviser relationship changes.

The merger of Schwab Advisor Services and TD Ameritrade Institutional created a dominant institutional custodian. The combined entity serves tens of thousands of advisory firms and trillions of dollars in assets, providing a durable, fee-generating institutional business that is largely independent of retail market conditions.

Bank lending

Through Schwab Bank, the company extends loans to retail clients and maintains a mortgage and loan portfolio. Pledged asset lines (PALs) allow clients to borrow against their investment portfolios without selling securities. The bank also held a portfolio of agency mortgage-backed securities, which became a source of duration and mark-to-market risk when rates rose sharply in 2022-2023 (discussed in the FAQ below).

Bank lending revenue is included within net interest income because loan interest and the portfolio income are part of the same spread calculation. The composition of Schwab Bank's earning asset portfolio (how much is in short-duration securities versus longer-duration mortgages and agency MBS) determines how quickly the bank can reprice in a changing rate environment, which in turn determines how net interest margin moves through a rate cycle.

Interest rate sensitivity and business model risk

The most important structural characteristic of Schwab's business model is its sensitivity to the interest rate environment. This is different from the risk profile of a pure broker or a pure asset manager. A pure broker's revenue depends on trading volumes and market activity. A pure asset manager's revenue depends on asset levels and fee rates. Schwab's primary revenue driver is the spread between short-term rates and the deposit rates it pays, which is a function of the Federal Reserve's policy rate.

This creates a business that earns more in high-rate environments and substantially less in low-rate environments, regardless of how well-run the underlying operations are. During the 2020-2021 near-zero rate period, Schwab's net interest income was compressed and earnings fell. During the 2022-2023 rate-hiking cycle, earnings rose sharply. As rates decline from 2024 onward, net interest income is again declining.

Investors and observers who compare Schwab's year-over-year earnings without adjusting for interest rate changes are comparing across incomparable environments. Schwab's management has tried to diversify revenue toward asset management and advisory fees, which are less interest-rate-sensitive, but the bank model remains the dominant revenue driver and the dominant source of earnings volatility.

For customers, this model means that Schwab's default behavior around cash sweep rates is directly tied to the company's profit motive in a way that creates a structural conflict: Schwab earns more when customers accept lower rates on idle cash. Understanding this is important for making informed decisions about where to hold uninvested cash within a Schwab account.
