Business Money Market Accounts: Compare Rates and Top Options

Business money market accounts are a low-risk way for business owners to earn money on idle cash. These accounts have an annual percentage yield, or APY, on par with traditional business savings accounts (if not higher), but they often include check-writing and debit card access.

While your funds are accessible, there are still limits on withdrawals. Many money market accounts cap transactions at six per month. Need more than that? Consider a business checking account.

On the flip side, you may find even higher rates with a business certificate of deposit, if you can stomach locking your funds up for a set term.

What is a business money market account?

A business money market account is a type of business savings account. Most money market accounts offer checks and/or debit cards so you can easily withdraw funds as needed. Like other business bank accounts, money market accounts are FDIC-insured up to $250,000 per depositor.

Interest rates on business money market accounts vary widely from one financial institution to the next: anywhere from 0.01% to more than 4%, depending on the balance you keep. Unlike business CDs, which lock in rates for a selected term, interest rates on these accounts are variable and can rise and fall depending on the rate environment.

Should you open a money market account for your business?

Business money market accounts are a good option for business owners to save emergency funds or excess operating funds. Figure out what balance you can reasonably deposit and maintain, then shop around for the best rates, comparing business money market accounts with other high-yield business accounts. 

If rates are similar and you're debating which savings vehicle is right for you, accessibility can be a useful deciding factor. 

• If you're OK not touching your money at all: Business CDs often offer higher rates than other business savings accounts, and that rate is locked in for your term (anywhere from a few months to a few years). Your funds are also locked up for the term, though, so this option is best for money you don’t need for at least 12 months. 

• If you don't want to be locked out entirely: A standard business savings account can deliver high-yield returns while still giving you access to your funds. You won’t get checks or even ATM access in most cases, but you can transfer money out of your business savings account if needed. Interest rates on business savings accounts are variable, which is a good thing in the current rate environment.

• If you want checks or a debit card, but you make six or fewer withdrawals per month:  Funds in a money market account are more accessible than a standard savings account — you can typically write checks or use a debit card — and you’re not locked in for a specific term, like with a business certificate of deposit. Most business money market accounts do impose transaction limits and charge fees if you exceed six withdrawals per month.

• If you need regular access to your money: High-yield business checking accounts typically have lower rates than other interest-bearing deposit accounts, but your money is easily accessible.

Business money market account rates

The national average rate for money market accounts is 0.63% APY as of this writing, according to the FDIC. While our picks for the best business money market accounts earn well above that rate, many money market accounts for businesses fall far below the national average.

Interest rates on business money market accounts are often tiered: The bigger your balance, the higher your interest rate. You may need a balance in the millions to earn the top-tier rate with some money market accounts. Rates can also vary by location, particularly if a bank has a regional or national footprint.
