Money market account interest rates vary by bank and change weekly, but most currently range from 4% to 5.35% annual percentage yield (APY)

The rate you earn depends on three things: which bank you choose, how much you deposit, and when you check. A large national bank might pay 4.5% APY, while an online bank might pay 5.25% APY for the same account opened on the same day. Rates shift because they follow the Federal Reserve's benchmark rate, which moves several times a year. This means the 5.2% you see today might be 4.9% in three months.

The only way to know the exact rate a specific bank is offering right now is to visit that bank's website or call them directly. Comparison sites like Bankrate, DepositAccounts, and NerdWallet update their listings daily and let you filter by rate, but they show what banks are advertising, not what you will personally receive until you open an account.

Key Takeaways

  • Money market account rates currently range from around 4% to 5.35% APY depending on the bank, and rates change weekly as the Federal Reserve adjusts its benchmark.
  • Online banks typically offer higher rates than brick-and-mortar banks because they have lower overhead costs.
  • Some banks pay higher rates only on balances above a certain threshold, such as $25,000 or $100,000, so check the tier structure before opening.
  • The rate you lock in when you open the account is not may provide—banks can lower rates at any time, though they must notify you in advance.

How bank size affects the rate you earn

Online-only banks almost always pay more than traditional banks with physical branches. An online bank has no tellers, no rent, and no regional offices, so it can pass those savings to depositors. A bank like Marcus, Ally, or American Express Personal Savings might pay 5.25% APY while Chase or Bank of America pays 4.5% APY on the same day.

Credit unions sometimes offer competitive rates too, though not always. Your rate depends on whether the credit union has money to lend and how much they need deposits. Some credit unions pay 4.8% APY; others pay 3.5%. The only way to know is to check with your specific credit union.

Tiered rates and minimum balance requirements

Many banks use a tiered structure: you earn one rate on the first $25,000, a higher rate on $25,000 to $100,000, and an even higher rate above $100,000. This means a $10,000 deposit might earn 4.5% APY while a $150,000 deposit earns 5.15% APY at the same bank.

Some banks advertise a headline rate that only applies to balances above a certain amount. Read the fine print before opening. If you have $15,000 to deposit and the top rate only kicks in at $50,000, you will earn the lower tier rate, not the advertised one.

Why rates change and what happens to your money

The Federal Reserve sets a target range for short-term interest rates. When the Fed raises rates, banks raise what they pay on savings accounts and money market accounts because they are competing for deposits. When the Fed cuts rates, banks cut what they pay you. The Fed has raised rates significantly since 2022, which is why money market rates are much higher now than they were in 2020 and 2021.

Your bank can lower your rate at any time, but federal law requires them to send you written notice at least 30 days in advance. You can then move your money to a different bank if the new rate is too low. This is why it makes sense to check rates every few months—if your current bank drops to 4.2% and another bank is paying 5.1%, you can transfer without penalty.

How to compare rates across banks

Start with a rate comparison site like Bankrate, DepositAccounts, or NerdWallet. Filter by account type (money market), sort by APY, and note the top five to ten options. Then visit each bank's website directly to confirm the rate is still current and to check whether there are tiered rates or minimum balance requirements the comparison site did not show.

Look for any fees that might eat into your earnings. Most money market accounts have no monthly fee, but some charge $10 to $25 per month if your balance falls below a minimum. A 5.2% rate on $10,000 earns you $520 per year—a $15 monthly fee costs you $180 per year, so the net rate drops to about 4.4%. Always subtract fees from the advertised rate to see what you actually keep.

What to do if rates drop after you open your account

When your bank lowers your rate, you have three options: stay put, move your money to a higher-paying bank, or split your deposit across multiple banks to lock in different rates at different times. There is no penalty for moving money out of a money market account—unlike a certificate of deposit (CD), which charges you if you withdraw early.

Some people keep their main balance at a bank paying 5.1% and move smaller amounts to a bank paying 5.3% when that rate is available. Others set a personal threshold—if their current rate drops below 4.8%, they move everything. The choice depends on how much time you want to spend managing the account and how much the rate difference matters to your savings goal.

The difference between APY and APR on money market accounts

APY (annual percentage yield) is what you actually earn because it includes compounding—interest paid on your interest. APR (annual percentage rate) is the simple interest rate before compounding. Banks are required to show you the APY, so that is the number to compare. If a bank shows 5.2% APY, that is what you will earn over a year if you do not touch the money.

Money market accounts compound interest daily or monthly depending on the bank. Daily compounding earns you slightly more than monthly compounding, but the difference is small—on a $10,000 balance at 5.2% APY, daily compounding might earn you $2 to $3 more per year than monthly compounding. It is not worth choosing a bank for this reason alone, but it is worth noting if two banks offer the same APY.

Frequently Asked Questions

Can the bank lower my rate without warning?

No. Federal law requires banks to send you written notice at least 30 days before lowering your rate. You can then move your money to a different bank without penalty. The notice must arrive by mail or email, depending on how you set up your account.

Is the rate I see online the rate I will get?

Usually yes, but not always. Some banks advertise a rate that only applies to new customers or to balances above a certain amount. Visit the bank's website and read the terms before opening. If you have questions, call the bank directly—they can tell you exactly what rate you will earn on your specific deposit amount.

Do I earn interest every day or once a month?

Most banks compound interest daily, meaning they calculate and add interest to your account every day. Some compound monthly. Daily compounding earns you slightly more, but the difference is small. The APY shown already accounts for how often the bank compounds, so you do not need to adjust for it yourself.

What happens to my rate if the Federal Reserve cuts interest rates?

Your bank will likely lower your rate within days or weeks. Banks cut rates faster than they raise them because they want to keep more of the interest spread. If your bank cuts rates and you do not like the new rate, you can move your money to a bank still paying more.

Should I lock in a rate by opening multiple accounts?

You can, but it is not necessary. Money market accounts do not have rate-lock periods like CDs do. If you want to lock in a rate, a CD is the better choice. If you want flexibility to move your money when rates change, a money market account is better—just check rates every few months and move if you find something higher.
