Key Takeaways
  • On $100,000 in a business money market account at 4.50% APY versus a traditional business MMA at 0.20% APY, the annual earnings difference is $4,300. On $250,000, the gap grows to $10,750 per year.
  • A business money market account is better than a savings account when you need occasional check-writing or debit access. It is better than business checking for any balance you do not need daily access to.
  • Most business MMAs use tiered rates: higher balances earn higher APYs. Confirm your typical balance hits the qualifying tier before opening.

The bottom line

A business money market account sits between business checking (maximum liquidity, minimal yield) and a business savings account (maximum yield, minimal access). It is the right tool when your business carries a reserve that you occasionally need to write a check against or transfer quickly, without going through the checking account. For a tax reserve, emergency fund, or vendor payment buffer that you rarely touch, a business savings account often pays as much or more. The MMA earns its place when you need occasional access that savings does not offer.

What $100,000 earns at different APYs

Dollar impact: $100,000 in business cash

At 4.50% APY (top online business MMA): $100,000 x 4.50% = $4,500/year

At 0.20% APY (traditional bank business MMA): $100,000 x 0.20% = $200/year

Annual gap: $4,300

At $250,000:

  • Top MMA at 4.50%: $11,250/year
  • Traditional at 0.20%: $500/year
  • Annual gap: $10,750

These are illustrative. Verify current APYs before opening.

The key insight: only operating cash belongs in a low-yield checking account. Tax reserves, emergency funds, and payroll buffers all earn meaningfully more in a savings or money market account.

When a business MMA beats a savings account

A business money market account is the right choice over a business savings account when:

  • You need to write occasional checks from the reserve (vendor payments, tax payments).
  • You want debit or ACH access without the friction of transferring from savings to checking first.
  • Your balance is large enough to qualify for the top tier rate, which may equal or exceed the savings rate.

A business savings account is preferable when:

  • You never need to write checks from the reserve.
  • The savings APY equals or exceeds the MMA APY.
  • You want the simplest possible setup.
Watch Out: Business money market accounts often have tiered rates. If your balance drops below the qualifying threshold (e.g., below $10,000 or $25,000), the rate resets to the lower tier, which can be 0.10% to 0.50% at some banks. Watch your balance and understand the tier structure.

When this recommendation changes

When the answer flips

If your balance regularly drops below the tier minimum: The high-tier rate disappears and a no-fee savings account may pay more for the same balance.

If you frequently write checks from the account: Consider a business checking account instead. Too many transactions on an MMA can trigger fees.

If rates fall: Business MMA rates are variable. If you want to lock a rate on long-horizon cash, a business CD may be the better move.

If your balance exceeds $250,000: Consider spreading across institutions or using an ICS account (Insured Cash Sweep) to maintain FDIC coverage on amounts above the single-institution limit.

Frequently Asked Questions

What is a business money market account?
A business money market account (MMA) is a deposit account that typically pays a higher APY than a standard checking account while providing limited check-writing or debit card access. It is FDIC or NCUA insured and combines some yield with limited liquidity, making it suitable for business reserves or funds you access occasionally.
What is the difference between a business savings account and a business money market account?
Both are deposit accounts that pay higher interest than checking. A business money market account typically allows check-writing and sometimes debit card access. A savings account usually does not. Money market accounts often have higher minimum balance requirements and may pay higher rates at higher tiers.
What APY can I expect on a business money market account?
Top business money market accounts pay APYs in the range of 4.00% to 5.00% APY, similar to top savings accounts. Traditional bank business money markets often pay less than 0.25%. Verify current rates with each institution, as they are variable and change with market conditions.
Is a business money market account FDIC insured?
Yes, if opened at an FDIC-member bank. Coverage is up to $250,000 per depositor per ownership category per institution. Business accounts held in the name of a legal entity (LLC, corporation) are insured separately from the owner's personal accounts at the same bank.
Can I use a business money market account as my main operating account?
Not typically. Business money market accounts are designed for reserves, not daily operations. Transaction limits may apply (some banks limit transfers out to 6 per month, a holdover from the old Regulation D rules). Use a business checking account for day-to-day operations and the MMA for reserves that earn yield.
What balance do I need to earn the best rate on a business MMA?
Many business money market accounts use tiered rates: a higher balance earns a higher APY. Some accounts require $10,000 to $25,000 to access the top tier. Check the tier structure before opening to confirm your typical balance qualifies for the advertised rate.
