Schwab offers interest on uninvested cash through its Cash Management Account and Money Market Fund options

When you hold cash in a Schwab brokerage account, that money does not automatically earn interest. You have to move it into a specific product designed to pay you a rate. Schwab's main options are the Schwab Bank Investor Checking account (which earns interest on your balance), the Schwab Money Market Fund, or a sweep into a money market mutual fund. The rate you earn depends on which product you choose and what the Federal Reserve's current rate environment is — rates change over time and vary by account type.

The simplest path for most people is the Schwab Bank Investor Checking account, which automatically sweeps uninvested cash into an interest-bearing account. You do not have to do anything after you set it up. If you want more control or are looking for a specific fund, you can also buy Schwab Money Market Fund shares directly or set up a sweep into a money market fund of your choice.

Key Takeaways

  • Schwab Bank Investor Checking automatically pays interest on your cash balance and is the easiest option if you want passive earnings.
  • Money market mutual funds and money market funds offer another route, but you have to buy shares yourself and monitor the fund.
  • Interest rates on all these products move with Federal Reserve policy and are not fixed — they change throughout the year.
  • You can check your current rate and earnings in your Schwab account dashboard under Cash Management or Account Details.

How Schwab Bank Investor Checking works

Schwab Bank Investor Checking is a checking account linked to your brokerage account. Any cash you deposit or hold in your brokerage account that is not invested in stocks, bonds, or funds automatically sweeps into this checking account, where it earns interest. You do not have to transfer money manually or buy anything — the sweep happens behind the scenes.

The account comes with a debit card, check-writing privileges, and no monthly fees. You can withdraw your cash anytime without penalty. The interest rate is variable, meaning Schwab adjusts it based on market conditions. Schwab publishes the current rate on its website, and you can see what you are earning in your account dashboard.

This account is useful if you want your cash to work for you without taking on investment risk or having to make decisions about where to put the money. It is also useful if you keep a cash reserve for emergencies or upcoming expenses — you earn something on it while keeping it liquid.

Money Market Fund options and how they differ

A money market fund is a mutual fund that invests in short-term, low-risk debt instruments like Treasury bills and commercial paper. Schwab offers its own Money Market Fund (ticker: SWVXX) and also lets you buy other money market funds. The yield on a money market fund is typically higher than a checking account rate, but it comes with a small trade-off: the value of your shares can fluctuate slightly, though the change is usually less than 0.01%.

To use a money market fund, you buy shares of the fund just as you would buy stock. You can set up an automatic sweep so that uninvested cash buys shares of the fund you choose, or you can buy shares manually. When you need the cash, you sell the shares — the sale usually settles in one business day.

Money market funds are useful if you want a slightly higher yield than a checking account and do not mind a tiny bit of price movement. They are also useful if you want to park cash for a few months or longer and do not need immediate access. However, if you need the money within days, the checking account is simpler because you can write a check or use the debit card without waiting for a fund sale to settle.

Setting up a cash sweep in your Schwab account

A cash sweep is an automatic instruction that tells Schwab where to put any uninvested cash. If you have Schwab Bank Investor Checking, the sweep is already set up by default — your cash goes into the checking account automatically. If you want to change where your cash goes, you can adjust the sweep settings in your account.

To change your sweep, log into your Schwab account, go to Account Settings, and look for Cash Management or Sweep Settings. You can choose to sweep into Schwab Bank Investor Checking, a money market fund, or another may be able to access fund. Once you set it, the sweep happens automatically whenever you have uninvested cash.

You can also turn off the sweep entirely if you want to hold cash without earning interest, though there is no reason to do that. Some people turn it off temporarily if they are about to make a large purchase and want to keep the cash separate, but most people leave it on.

What interest rates are available right now

Interest rates on Schwab cash products change frequently because they are tied to the Federal Reserve's benchmark rate. When the Fed raises rates, Schwab's rates go up. When the Fed cuts rates, Schwab's rates go down. The exact rate you earn depends on which product you choose and when you check.

Schwab publishes current rates on its website under the Cash Management section. You can also see your rate in your account dashboard. Money market funds typically offer a yield that is slightly higher than the checking account rate, but the difference is usually small — often less than 0.25%.

Because rates change, it is worth checking your rate a few times a year to see if Schwab has adjusted it. You do not have to do anything if the rate changes — your money stays where it is and earns the new rate automatically.

Comparing Schwab cash earnings to other banks

Schwab's rates on cash products are competitive but not always the highest available. Online banks and some credit unions sometimes offer higher rates on savings accounts or money market accounts. However, if you already have a Schwab brokerage account, keeping your cash at Schwab is convenient because you do not have to move money between accounts or manage multiple logins.

The trade-off is simplicity versus yield. If earning an extra 0.10% or 0.20% per year is important to you, you might shop around at other banks. If you value having everything in one place and do not want to manage multiple accounts, Schwab's rates are reasonable and the setup is straightforward.

Keep in mind that rates change, so a bank that offers a high rate today might lower it next month. Schwab tends to adjust its rates in line with Fed policy, so you can expect consistency rather than surprise rate cuts.

Tax treatment of interest earned on Schwab cash

Interest you earn on cash in a Schwab account is taxable income. Schwab sends you a Form 1099-INT at the end of the year showing how much interest you earned. You report this on your tax return as ordinary income.

If your Schwab account is a traditional IRA or Roth IRA, the interest is not taxed in the year you earn it — it grows tax-deferred (traditional) or tax-free (Roth). If your account is a regular taxable brokerage account, you owe tax on the interest in the year you earn it, regardless of whether you withdraw the money.

The amount of tax you owe depends on your tax bracket. If you earn $500 in interest and you are in the 24% tax bracket, you owe about $120 in federal tax on that interest. This is one reason some people prefer money market funds in taxable accounts — the yield is slightly higher, which can offset some of the tax impact, though the difference is usually small.

Frequently Asked Questions

Can I earn interest on cash in a Schwab brokerage account without opening a separate checking account?

Yes. Schwab Bank Investor Checking is linked to your brokerage account, not separate from it. Your cash stays in your brokerage account and earns interest automatically — you do not have to open a new account or move money anywhere. The checking account is just the vehicle Schwab uses to pay you interest.

What happens if I need my cash quickly?

If your cash is in Schwab Bank Investor Checking, you can withdraw it immediately using the debit card, writing a check, or transferring it to another bank account. If your cash is in a money market fund, you sell the shares and the cash settles in one business day. Both options are fast enough for most situations.

Is my cash safe if I keep it in a money market fund instead of a checking account?

Money market funds are not FDIC insured the way a checking account is, but they are very low-risk because they invest only in short-term government and corporate debt. The value of your shares can move slightly, but the movement is usually tiny. If safety is your main concern, the checking account is the safer choice because it is FDIC insured up to $250,000.

Can I set up a sweep into a money market fund that is not a Schwab fund?

Yes. Schwab lets you sweep into other money market funds, though you may have to set it up manually rather than through a dropdown menu. Call Schwab or check your account settings to see which funds are available for automatic sweep.

How often does Schwab change its interest rates?

Schwab typically adjusts rates when the Federal Reserve changes its benchmark rate, which happens several times a year. Schwab may also adjust rates between Fed meetings if market conditions shift significantly. You can check your current rate anytime in your account dashboard.
