The highest APY changes weekly, so there is no permanent answer

The bank with the highest APY today will not have it next month. Interest rates move based on Federal Reserve decisions, market competition, and how much money each bank wants to attract. Online banks and credit unions tend to lead traditional brick-and-mortar banks, but the gap shrinks and widens constantly.

Right now, some online savings accounts and money market accounts pay between 4% and 5.35% APY, while traditional banks often pay 0.01% to 0.5%. But those numbers shift. A bank that pays 5% one week might drop to 4.75% the next if they have enough deposits. The only way to know what is available today is to check current rates yourself—not to read an article written last month.

What matters more than chasing the highest rate is understanding where to look and what catches your money if a bank changes its rate after you deposit.

Key Takeaways

  • Online banks and credit unions currently offer higher APY than traditional banks, but rates change weekly based on Federal Reserve policy and bank competition.
  • Money market accounts and high-yield savings accounts are the two account types most likely to pay competitive rates; regular savings accounts almost never do.
  • Your deposits are protected up to $250,000 per account type per bank by FDIC insurance (or NCUA insurance at credit unions), regardless of the rate offered.
  • A bank can lower its APY without notice after you open the account, so locking in a rate is not possible—only moving your money if rates drop elsewhere.
  • Comparing rates across multiple banks takes 15 minutes and can mean hundreds of dollars more per year on a $10,000 deposit.

Where the highest rates actually live

Online-only banks pay more than branches because they have no physical locations to maintain. They pass the savings to depositors through higher rates. Marcus by Goldman Sachs, Ally Bank, American Express Personal Savings, and Discover Bank have historically competed for the top spot, but the leader changes. Credit unions like Connexus Credit Union and Pentagon Federal Credit Union also run competitive rates, though you must meet membership requirements to open an account.

Money market accounts typically pay slightly more than high-yield savings accounts at the same bank, but the difference is often less than 0.1%. The trade-off is that money market accounts may limit how many withdrawals you can make per month (though this rule is rarely enforced now). If you need to move money in and out frequently, a high-yield savings account is simpler.

Traditional banks—Chase, Bank of America, Wells Fargo, Citibank—rarely compete on rate. They rely on branch convenience and brand recognition instead. Their savings accounts typically pay 0.01% to 0.05% APY. If you keep money at a traditional bank for the rate, you are leaving hundreds of dollars on the table each year.

How to find and compare rates today

Bankrate, DepositAccounts, and the Federal Reserve's own National Information Center let you filter by account type and see current rates across dozens of banks. Enter your state (some banks operate regionally), sort by APY, and note the top five. Then visit each bank's website directly to confirm the rate has not changed since the comparison site updated.

Check the minimum deposit requirement and any conditions tied to the rate. Some banks pay the advertised rate only if you maintain a certain balance or set up direct deposit. Others pay the full rate on all balances. Read the fine print before opening an account.

Once you have narrowed it to two or three banks, open an account at the one with the highest rate and the lowest friction. If the rate drops later, you can move your money to a new bank—it takes about five business days for an ACH transfer to clear.

What happens when a bank lowers its rate

Banks can lower APY without notice and without your permission. You will not receive a warning email or a phone call. You may see the rate drop when you log in, or you might not notice until you check your monthly statement and see less interest posted than before.

You have no contractual right to keep the old rate. The bank can change it at any time. Your only recourse is to move your money elsewhere. Most online banks make this easy—you can initiate a transfer online in minutes, and the funds arrive within five business days.

This is why comparing rates every few months makes sense if you have a large balance. A 0.5% drop on $50,000 costs you $250 per year. Moving that money to a bank paying 0.5% more takes 15 minutes and five days.

FDIC and NCUA insurance protects your deposits regardless of rate

The rate a bank pays has nothing to do with how safe your money is. FDIC insurance covers up to $250,000 per depositor per bank per account type. That means if you have $250,000 in a savings account and $250,000 in a money market account at the same FDIC-insured bank, both are fully protected if the bank fails.

Credit unions are insured by NCUA (National Credit Union Administration) under the same $250,000 limit. Online banks are FDIC-insured just like traditional banks. A bank paying 5% APY is no riskier than one paying 0.01%—the insurance is identical.

Before opening an account, confirm the bank displays an FDIC or NCUA logo on its website. If it does not, the deposits are not insured, and you should not keep money there.

The math: how much the rate difference actually costs you

The gap between a traditional bank (0.05% APY) and an online bank (4.5% APY) is enormous in real terms. On a $10,000 deposit held for one year:

  • Traditional bank at 0.05%: $5 in interest
  • Online bank at 4.5%: $450 in interest
  • Difference: $445 per year

On $50,000, that gap becomes $2,225 per year. On $100,000, it is $4,450. These are not small numbers. Moving money to a higher-rate bank is one of the few ways to earn more on cash you are already holding without taking risk.

The rate matters most if you are saving for a goal six months to two years away and do not want to invest in stocks or bonds. For money you need within weeks, the rate barely matters. For money you will not touch for five years, a stock index fund or bond fund will likely outpace any savings account rate.

Account features that matter as much as the rate

A bank paying 5% APY is not worth it if you cannot access your money when you need it. Check whether the bank allows unlimited transfers out, or if it caps you at six per month (some still do, though the rule is rarely enforced). Confirm you can link an external bank account for transfers in and out.

Some online banks have weak customer service or slow transfer times. Read recent reviews on Trustpilot or the Better Business Bureau to see if people report problems. A 0.1% rate difference is not worth switching to a bank with a reputation for freezing accounts or losing deposits.

Also check whether the bank offers a checking account. If you plan to move your paycheck there, having both savings and checking at the same bank makes life simpler. Some online banks (like Ally) offer both; others (like Marcus) offer only savings.

Frequently Asked Questions

Can I lock in a rate so the bank cannot lower it?

No. Savings accounts and money market accounts do not have fixed rates. The bank can change the APY at any time without notice. Certificates of deposit (CDs) do lock in a rate, but you cannot withdraw the money early without paying a penalty. If you want a may provide rate, a CD is the only option.

Is an online bank safe if it pays way more than my current bank?

Yes, as long as it is FDIC-insured. Online banks pay more because they have lower overhead, not because they take more risk. Check the FDIC logo on the website, and your deposits are protected the same way they are at Chase or Bank of America.

How often should I check rates and move my money?

Check rates every three to six months if you have a large balance ($25,000 or more). If rates have dropped 0.5% or more at your current bank, moving to a higher-rate bank makes financial sense. For smaller balances, the interest difference is small enough that moving every year or two is fine.

What if I need the money in a few weeks—does the rate matter?

Not much. On $10,000 held for one month, the difference between 0.05% and 4.5% APY is about $3.70. The convenience of keeping money at your current bank is probably worth more than that. For money you will hold longer than three months, the rate starts to matter.

Do I have to pay taxes on the interest I earn?

Yes. Interest earned in a savings account or money market account is taxable income. The bank will send you a 1099-INT form at the end of the year if you earned $10 or more in interest. Report it on your tax return as ordinary income.
