A money market account (MMA) is a bank deposit account that pays more than a standard savings account and often includes limited check-writing and debit card access. On the bank pages we read on October 15, 2026, money market accounts at online banks paid about 3.40%-4.05% APY — comparable to the best high-yield savings accounts — while the FDIC national average for money market accounts was 0.63% (October 19, 2026).
What Is a Money Market Account?
A money market account is a federally insured deposit account offered by banks and credit unions. It works like a savings account — your money earns interest while it sits — but may also let you write checks or use a debit card, which a standard savings account does not allow.
Key characteristics:
| Feature | Money Market Account | Regular Savings Account |
|---|---|---|
| Interest rate (top online banks we checked, Oct. 2026) | 3.40%–4.05% APY | 3.10%–4.05% APY (Ally to Bread Savings) |
| Interest rate (FDIC national avg) | 0.63% APY (Oct. 2026) | 0.38% APY (Sept. 2026) |
| Check writing | Often yes | No |
| Debit card | Sometimes | Rarely |
| Minimum balance | $0–$25,000 | $0–$500 |
| FDIC insured | Yes | Yes |
| Withdrawal limits | Varies by bank | Varies by bank |
How Money Market Accounts Work
When you deposit money into an MMA, the bank pays you interest — typically daily, credited monthly. The bank uses your deposits (along with others) to fund loans and investments. Because banks require a larger average balance to offer MMA features like checks, they typically pay slightly different rates than on basic savings accounts.
Online banks compete aggressively for MMA deposits and often offer the highest rates with the lowest minimum balances.

Who Should Open a Money Market Account?
Best fit for:
- An emergency fund you want to access occasionally without a full transfer
- Savings above your regular checking buffer
- Anyone who wants check-writing access without a fully transactional checking account
- People with larger cash reserves who want higher FDIC coverage (use multiple banks to exceed $250K limit)
Less ideal for:
- Day-to-day spending (use a checking account)
- Long-term savings goals where a CD lock-in would earn more
- People who need frequent access and don’t want to manage balances
Money Market Account vs. Alternatives
| Account type | Best for | Top APYs we checked (Oct. 2026, confirm) | Access |
|---|---|---|---|
| Money market account | Flexible high-yield savings | 3.40%–4.05% | Checks + debit |
| High-yield savings account | Pure savings, no spend | 3.10%–4.05% | Transfer only |
| CD | Fixed-term savings | 12-month rates we read ranged from 3.50% to 4.50% (Oct. 2026) | Locked (penalty to withdraw) |
| Checking account | Daily spending | 0.00%–1.00% | Full |
| Money market fund | Short-term investing | Roughly tracks short-term Treasury yields (~3.5%–4.0%) — confirm current fund yield | Not FDIC insured |
FDIC Safety
All money market accounts at FDIC-member banks are insured up to $250,000 per depositor, per bank, per ownership category. This is the same protection as a savings account or checking account.
Important: Money market funds — sold by brokerages and mutual fund companies — are completely different. They are investment products, not bank accounts, and are not FDIC insured. Never confuse the two.
