Money Market Rate Trends
Daily average APYs for business and standard money market accounts
Compiled from thousands of money market rates across 8,500+ banks and credit unions — updated every evening.
What Is a Business Money Market Account?
A business money market account is a deposit account specifically designed for companies, partnerships, LLCs, and sole proprietors. It earns interest on idle cash while keeping business funds legally separate from personal finances — a critical requirement for liability protection, tax compliance, and clean bookkeeping.
All legitimate business money market accounts at FDIC-member banks are insured up to $250,000 per depositor. Credit union equivalents carry NCUA protection for the same amount. Businesses with balances exceeding coverage limits should consider distributing deposits across multiple institutions.
How to Choose a Business Money Market Account
Beyond the headline APY, evaluate: monthly maintenance fees and how to waive them, minimum balance requirements to earn the advertised rate, ACH and wire transfer capabilities, check-writing privileges, and whether the institution also offers business checking or lending services. MonitorBankRates displays each institution’s Safety Grade, Star Rating, and Texas Ratio so you can assess financial health alongside rate competitiveness.
What Idle Operating Cash Could Be Earning
Most businesses hold more in low-yield checking than they need for near-term obligations. Here is what a year of interest looks like on a reserve balance at the current business money market average versus the top verified offer in our table.
| Balance | Earned in 1 Year at 1.11% APY Business average |
Earned at 5.00% APY Top offer in our table | Difference |
|---|---|---|---|
| $10,000 | $110.68 | $500.00 | $389.32 |
| $50,000 | $553.40 | $2,500.00 | $1,946.60 |
| $100,000 | $1,106.80 | $5,000.00 | $3,893.20 |
| $250,000 | $2,767.00 | $12,500.00 | $9,733.00 |
| $500,000 | $5,534.00 | $25,000.00 | $19,466.00 |
Assumes the rate holds for the full year with no withdrawals and monthly compounding. Business money market APYs are variable and usually tiered, and any monthly maintenance fee not waived would reduce these figures. Interest earned is business income and is generally taxable.
Business vs. Personal Money Market Accounts
A business money market works the same way mechanically, but the account terms, paperwork, and fee structure differ in ways that matter once real operating cash is involved.
| Business Money Market | Personal Money Market | |
|---|---|---|
| Who Can Open It | Registered entity — EIN, formation documents, and an authorised signer list | An individual, with an SSN |
| Typical APY | ● Often slightly below personal tiers | ✓ Usually the higher advertised rates |
| Balance Tiers | Common — rates step up at higher operating balances | Common, but tiers start lower |
| Monthly Fees | ● More likely, often waived above a balance minimum | Frequently none |
| Multiple Signers | ✓ Yes — and dual-control options for larger organisations | ✗ Owner and joint owner only |
| Sweep & Treasury Services | ✓ Often available — automatic transfer of idle checking cash | ✗ Rarely offered |
| Deposit Insurance | $250,000 per depositor, per institution, per ownership category — the business is the depositor | $250,000, with the individual as depositor |
A business and its owner are separate depositors for insurance purposes, so a company account and a personal account at the same institution are insured separately — provided the business is a genuinely distinct legal entity. Sole proprietorship funds are generally insured together with the owner’s personal accounts. Confirm your situation with the institution.
What to Check Before Moving Operating Cash
The highest APY is the wrong thing to optimise if the account can’t support how your business actually moves money. Work through these four first.
Transaction Limits and What They Cost
Money market accounts commonly cap the number of outbound transfers and cheques per statement cycle, with a per-item fee beyond that. If the account is going to fund payroll or vendor runs, count your actual monthly transactions before committing — excess fees can wipe out the yield advantage entirely.
Whether the Fee Waiver Is Realistic
Monthly maintenance fees are common on business accounts and usually waived above a minimum balance. Check whether that minimum is an average daily balance or an absolute floor — if your balance dips near month-end when payables clear, an absolute floor will trigger the fee.
Sweep Arrangements
A sweep automatically moves idle cash from operating checking into the money market overnight and back when needed. It is the difference between earning on your average balance and earning on the balance you remember to transfer. Ask what the sweep threshold and timing are.
Signers and Controls
Confirm how many authorised signers the account supports, whether dual approval is available for outbound transfers, and how quickly signers can be changed. For any business beyond an owner-operator, these controls matter more than a few basis points.
Split operating cash into two buckets: the float you touch weekly, which belongs in checking where transaction limits don’t apply, and the reserve you don’t expect to need for months, which belongs here earning yield. Trying to run both from one money market account is what triggers excess-transaction fees.
About Our Business Money Market Rate Database
This page tracks money market accounts available to businesses, drawn from the thousands of verified rates in our database. Every APY is sourced directly from the institution’s own website and re-verified regularly. Business account terms vary more than personal ones — confirm transaction limits, fee waivers, and signer requirements directly with the institution before opening.
The highest verified APY in our table right now is 5.00% APY from Elkton Bank & Trust Company. Money market APYs are variable — the institution can change the rate at any time without notice, so today’s leader may not lead next quarter.

Assumes the APY holds for the entire period and interest compounds monthly with no withdrawals. Money market rates are variable and tiered, and this model does not deduct monthly maintenance fees or excess-transaction charges, which can materially reduce net yield on a business account. Interest is generally taxable business income. Not a rate guarantee, an offer, or tax advice.
