Best Money Market Accounts: How to Compare MMA vs HYSA
Quick answer
A money market account (MMA) is a deposit account that typically pays interest and offers limited check-writing or debit access — a middle ground between a savings account and checking. It suits money you want to keep accessible but not spent daily: an emergency fund you might need by check, or savings you want slightly more reachable than a CD. It is not a money market *fund* (an investment product, not FDIC-insured) — do not confuse the two.
Key takeaways
- A money market account blends savings-level yield with limited check and debit access — a middle ground between savings and checking.
- Compare the APY at your balance, not the top tier: tiered rates can pay much less on a modest balance.
- Check minimums, monthly fees and waiver conditions, monthly transaction limits, and how and when the variable rate changes.
- Confirm FDIC (bank) or NCUA (credit union) insurance; the standard limit is $250,000 per depositor, per institution, per ownership category.

Our HYSA-vs-money-market comparison explains the yield/access trade-off in depth; this page focuses on how to choose among MMAs themselves.
• Typical yield: Money market account: Competitive with savings; often tiered by balance; High-yield savings: Often the highest deposit yield; Checking: Low or none
• Access: Money market account: Checks/debit, often with monthly transaction limits; High-yield savings: Transfers; no checks usually; Checking: Unlimited transactions
• Best for: Money market account: Accessible emergency/goal savings; High-yield savings: Maximum yield on idle savings; Checking: Daily spending and bills
• Insurance: Money market account: FDIC/NCUA deposit insurance; High-yield savings: FDIC/NCUA deposit insurance; Checking: FDIC/NCUA deposit insurance
Worked example (hypothetical, tiers matter)
Suppose an MMA advertises a top-tier APY but only above a high balance, with a lower APY below it. A saver with a modest balance earns the lower tier — possibly less than a straightforward high-yield savings account with no tiers. Always locate your tier before comparing headlines. APY itself is explained in our how-APY-works guide: it annualizes the rate including compounding, so compare APY to APY, not APY to a simple interest rate.
When an MMA is the wrong tool
• Daily spending: transaction limits and fees make checking better.
• Money you must not touch until a date: a CD's fixed term enforces discipline (with an early-withdrawal penalty as the cost of breaking it).
• Maximum yield above all: a no-tier HYSA may beat a tiered MMA at your balance.
Checklist
1. Confirm FDIC/NCUA insurance and the institution's status.
2. Find your APY tier at your actual balance.
3. Check monthly fee, waiver, and transaction limits against your expected use.
4. Confirm check/debit access works the way you expect (some MMAs limit check writing).
5. Re-check the rate periodically — variable means variable.
At a glance
| Criterion | What to check |
|---|---|
| APY and tiers | Rate at your balance, not the top tier you will never reach; how tiers are structured |
| Minimums | To open, to avoid a monthly fee, to earn the advertised APY |
| Monthly fee + waiver | Fee amount and realistic waiver condition |
| Transaction limits | Monthly check/debit/transfer limits and excess-transaction fees |
| Access | Debit card, checks, ATM network, mobile deposit |
| Insurance | FDIC (bank) or NCUA (credit union); $250,000 standard limit per depositor, per institution, per ownership category |
| Rate variability | MMAs pay variable rates; ask how and when the rate changes |
Comparison criteria
What this means for you
An MMA earns its place only when your balance actually reaches its paying tier and you stay inside its transaction limits. Otherwise the simpler high-yield savings account usually pays more for less effort.
FAQ
Is a money market account the same as a money market fund?
No. An MMA is a bank/credit-union deposit account, FDIC/NCUA-insured up to the standard limit. A money market fund is an investment product, not insured, and its value can fluctuate.
Can I write checks from an MMA?
Usually yes, within transaction limits — confirm check availability, limits, and any excess-transaction fee before relying on it for bills.
