A money market account works best if you have money sitting idle and want a higher rate than a regular savings account, but you need to be able to leave it mostly untouched for months at a time.
Money market accounts pay more interest than standard savings accounts because banks can lend out your money for longer periods. The tradeoff is that you get limited withdrawals per month—usually three to six—before fees kick in or the account converts to a regular savings account. If you need to move money in and out frequently, a money market account will frustrate you and cost you money.
The real question is whether the higher rate is worth the withdrawal restrictions for your specific situation. That depends on what you're saving for, how soon you might need the money, and what rates your bank is actually offering right now.
Key Takeaways
- Money market accounts pay higher interest than regular savings accounts because they restrict how often you can withdraw money each month.
- Most banks limit you to three to six withdrawals per month before charging a fee or closing the account.
- A money market account makes sense only if you have money you won't need to touch for at least several months.
- Compare the interest rate difference between a money market account and a high-yield savings account at your bank—sometimes the gap is too small to justify the restrictions.
- If you need the money within a few months or expect to make frequent transfers, a regular high-yield savings account is usually the better choice.
When the withdrawal limits actually matter
Federal rules allow banks to limit money market accounts to six withdrawals per month. Most banks set the limit at three to six. If you go over, you'll either pay a fee (usually $10 to $25 per excess withdrawal) or the bank will convert your account to a regular savings account, which means you lose the higher interest rate.
This sounds like a minor inconvenience until you actually need the money. If you're saving for a car down payment and you want to move money to your checking account to make the purchase, that's one withdrawal. If you need to transfer money to pay a medical bill two weeks later, that's two. If you're using the account as a backup emergency fund and you make a withdrawal, then realize you need more a few days later, you've hit your limit and now you're paying fees.
The restriction is designed to keep you from treating it like a checking account. If you find yourself thinking "I might need this soon," a money market account is the wrong tool.
Compare the rate difference at your actual bank
The interest rate advantage of a money market account over a regular savings account varies by bank and changes constantly. Some banks offer nearly identical rates on both products. Others pay 0.5% more on a money market account. That difference matters only if you're keeping a large balance for a long time.
If you have $10,000 and your bank pays 4.5% on a money market account and 4.0% on a high-yield savings account, the difference is about $50 per year. If you have $50,000, it's about $250 per year. But if you pay a $25 fee because you needed to make a fourth withdrawal, you've erased months of that gain.
Check your bank's website or call and ask for the current rates on both products. Calculate what you'd actually earn in a year, then decide whether that amount is worth the withdrawal restrictions.
Money market accounts work for specific savings goals
A money market account makes sense if you're saving for something you know you won't need for at least six months to a year. Examples include a down payment on a home (if you're not buying when ready), a car purchase planned for next year, or a vacation fund you're building over several months.
The key is that you know roughly when you'll need the money and you're confident you won't have to touch it before then. You're also comfortable with the fact that if an emergency happens, you can withdraw the money but you'll either pay a fee or lose the higher rate.
A money market account does not work well for emergency funds, because emergencies don't follow your withdrawal limit. It also doesn't work for money you might need within the next few months, or for savings you're actively adding to each week or month.
High-yield savings accounts often offer the same benefit without the restrictions
Many banks now offer high-yield savings accounts with rates nearly as high as money market accounts, and with no withdrawal limits. You can move money in and out as often as you need without penalties or losing the rate.
If your bank's high-yield savings rate is within 0.25% of its money market rate, the high-yield savings account is almost always the better choice. You get most of the interest benefit and all of the flexibility. The only reason to choose a money market account is if the rate difference is significant enough to justify the restrictions.
Some online banks and credit unions offer particularly competitive high-yield savings rates. It's worth checking what's available outside your current bank before deciding.
What happens if you exceed the withdrawal limit
The consequence depends on your bank's policy. Some charge a fee per excess withdrawal, usually $10 to $25. Others convert the account to a regular savings account, which means future interest payments drop to the regular savings rate. A few banks will straightforward refuse the withdrawal and ask you to move the money to a checking account first.
Read your account agreement or call the bank and ask what happens if you make more than the allowed withdrawals. This matters because it changes whether the account is actually usable for your situation. If your bank charges $25 per excess withdrawal, you need to be very confident you won't exceed the limit.
The math: when the higher rate is worth it
Use this straightforward calculation to decide. Take the difference between the money market rate and the high-yield savings rate at your bank. Multiply that by your balance. That's your annual gain from choosing the money market account.
For example: if you have $25,000, the money market rate is 4.5%, and the high-yield savings rate is 4.0%, the difference is 0.5%. That's $125 per year. If you're confident you won't make more than three withdrawals in a year, that's a reasonable gain. If you think you might make five or six withdrawals, the risk of fees outweighs the benefit.
If the rate difference is 0.1% or less, the math almost never works in favor of the money market account. The gain is too small to justify the restrictions.
Frequently Asked Questions
Can I use a money market account as an emergency fund?
Technically yes, but it's not ideal. Emergencies don't respect withdrawal limits. If you need to make multiple withdrawals in a month, you'll hit the limit and either pay fees or lose the higher rate. A regular high-yield savings account is better for emergency money because you can access it freely.
What's the difference between a money market account and a money market fund?
A money market account is a bank product insured by the FDIC up to $250,000. A money market fund is an investment product that's not insured and can lose value. They're completely different despite the similar names. This article covers accounts, not funds.
Do I need a minimum balance to open a money market account?
Most banks require a minimum opening deposit, usually $1,000 to $2,500, though some have no minimum. Many also require you to maintain a minimum balance to avoid a monthly fee. Check your bank's requirements before opening.
Can I add money to a money market account whenever I want?
Yes. The withdrawal limit applies only to money coming out, not money going in. You can deposit as much as you want whenever you want. The restriction is on how often you can take money out.
What if my bank's money market rate drops after I open the account?
Banks can change rates at any time. Your rate will adjust, usually within a few days of the bank's announcement. This is normal and happens with all savings products. If rates drop significantly, you can move your money to a different bank, though you'll need to close the account and open a new one elsewhere.
