- 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.

Liquidity vs yield matrix: picking the right business cash account
| Account type | Yield potential | Daily access | Check-writing | Best for |
|---|---|---|---|---|
| Business checking | Low to none | Full | Yes | Operating cash, payroll |
| Business savings | High | Limited (transfer) | No | Tax reserves, emergency fund |
| Business MMA | High | Limited (transfer + check) | Often yes | Flexible reserves, vendor payments |
| Business CD | Highest (locked) | No (penalty) | No | Long-horizon savings |
| Treasury bills / money funds | Competitive | 1 to 3 days | No | Large balances, tax efficiency |
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.
When this recommendation changes
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.
