The banks and credit unions offering the best rates change month to month

There is no single "best" savings account because interest rates shift constantly and different account types pay different amounts. Right now, online banks typically offer higher rates than brick-and-mortar banks—sometimes 4% to 5% APY on savings accounts, compared to 0.01% at major national chains. Credit unions often match or beat online bank rates, but only for their members. The rate you actually receive depends on the account type (regular savings, money market, or high-yield savings), your balance, and which institution you choose.

The practical approach is to check current rates at three to five institutions that fit your situation, then move your money where the rate is highest. Rates change frequently enough that a rate that was best last month may not be best this month. You are not locked in—you can move money between accounts without penalty, though it takes one to three business days for the transfer to clear.

Key Takeaways

  • Online banks and credit unions currently offer the highest savings rates, typically between 4% and 5% APY, while traditional banks offer less than 0.1%.
  • The rate you receive depends on account type, your balance, and the specific institution—there is no universal "best" choice.
  • Interest rates change weekly or monthly, so comparing rates across multiple banks before opening an account takes 15 minutes and can save you hundreds of dollars per year.
  • You can move money between savings accounts without penalty, so switching to a higher rate later is always an option.
  • Money market accounts and certificates of deposit sometimes pay more than regular savings accounts, but they restrict how often you can withdraw.

Online banks versus traditional banks: why the gap exists

Online banks have lower overhead costs than physical branches, so they pass some of that savings to customers through higher interest rates. They do not maintain buildings, teller staff, or ATM networks. A traditional bank with hundreds of branches needs to cover those costs, which means less money left over to pay you on your savings.

The tradeoff is convenience. An online bank has no branch you can walk into, no teller to speak with, and no ATM network of its own (though many partner with ATM networks or reimburse fees). If you need to deposit cash or speak to someone in person regularly, a traditional bank may be worth the lower rate. If you rarely need those services, an online bank's rate advantage usually outweighs the inconvenience.

Credit unions: membership requirements and rate advantages

Credit unions are member-owned cooperatives that often pay rates as high as online banks. Some credit unions currently offer 4% to 5% APY on savings accounts, matching or beating online banks. The catch is membership—you must meet the credit union's membership requirements before you can open an account. Requirements vary widely: some credit unions accept anyone in a geographic area, others require you to work for a specific employer, belong to a certain organization, or have a family member who is already a member.

If you already may have access to for membership at a credit union, check their rates before opening an account at an online bank. If you do not may have access to for any credit union, online banks are usually your best option. Some people maintain accounts at both a credit union and an online bank to take advantage of whichever has the higher rate at any given time.

How to compare rates across institutions

Start by listing the institutions you can actually use. If you have a workplace, check whether your employer has a credit union. If you have family members who are credit union members, ask which credit union they use and whether you can join. Then add three to five online banks to your list. Visit each institution's website and look for the savings account rate—it is usually displayed prominently on the homepage or under a "Rates" or "Products" tab.

Write down the APY (annual percentage yield), the minimum balance required to earn that rate, and any monthly fees. Some banks pay the advertised rate on all balances; others pay a lower rate if your balance falls below a threshold. A few charge monthly maintenance fees that eat into your earnings. After you have gathered rates from all your options, move your money to whichever account offers the highest rate with no monthly fee and a minimum balance you can meet.

Money market accounts and CDs: when they pay more than savings accounts

Money market accounts sometimes pay slightly higher rates than regular savings accounts at the same institution, but the difference is usually small—often 0.1% to 0.3% higher. The tradeoff is that money market accounts typically limit how many withdrawals you can make per month, usually six. If you need to withdraw money frequently, a regular savings account is more practical even if the rate is slightly lower.

Certificates of deposit (CDs) often pay the highest rates available, sometimes 5% to 6% APY. The catch is that your money is locked in for a set period—three months, six months, one year, or longer. If you withdraw before the term ends, you pay a penalty that can wipe out months of interest. CDs make sense only if you know you will not need the money for the full term and you want to lock in a rate before rates fall.

What happens to your rate if you move your money later

If you open a savings account at a bank offering 4.5% APY and the rate drops to 4% next month, you keep earning 4.5% on your balance. Banks do not lower your rate retroactively. However, if rates rise and you want to move to a higher-paying account, you can transfer your money without penalty. The transfer takes one to three business days, and you will start earning the new rate once the money clears.

Some banks offer "rate bumps" or "rate match guarantees" that let you request a higher rate if the bank raises its rates within a certain period after you open the account. These are rare and usually come with conditions, so read the fine print. In most cases, the simplest approach is to move your money when a significantly better rate becomes available elsewhere.

Frequently Asked Questions

Do I lose interest if I move my money to a different bank?

No. You earn interest up to the day the money leaves your account. Once it arrives at the new bank, you start earning interest at the new rate. The transfer itself takes one to three business days, during which the money is in transit and earning nothing, but this is usually only a few dollars of lost interest.

What if I need to withdraw money before the year is over?

Regular savings accounts and money market accounts let you withdraw anytime with no penalty. CDs charge an early withdrawal penalty if you take money out before the term ends—usually three to six months of interest. Check the penalty amount before opening a CD.

Is my money safe in an online bank?

Online banks are regulated the same way as traditional banks. Most are FDIC-insured, meaning deposits up to $250,000 per account are protected if the bank fails. Check the bank's website to confirm FDIC insurance before opening an account.

Can the bank lower my interest rate after I open the account?

Yes, banks can lower rates at any time. However, they cannot lower your rate retroactively—you keep your current rate on existing balances. If the bank lowers its rate, you can move your money to a higher-paying account without penalty.

How often should I check rates to see if I should move my money?

Rates change weekly or monthly, but moving money for a 0.1% difference costs more in time than you gain in interest. Check rates every three to six months, and move your money only if you find a rate that is at least 0.5% higher than what you are currently earning.
