No single bank offers the best rate for everyone, because rates change weekly and depend on the account type you choose
The bank with the highest savings rate today will not have it next month. Interest rates move based on what the Federal Reserve does, what other banks are offering, and what type of account you open—a money market account pays differently than a savings account, which pays differently than a certificate of deposit (CD). You cannot compare one bank's rate to another without knowing the account type, the deposit amount required, and when you checked.
The fastest way to find the current highest rate is to visit a rate-comparison site like Bankrate, DepositAccounts, or NerdWallet, filter by account type, and sort by APY (annual percentage yield). These sites update daily. Then visit the bank's own website to confirm the rate has not changed since the comparison site last pulled data—sometimes there is a lag of a few hours.
Online banks almost always beat brick-and-mortar banks on savings rates because they have lower overhead costs. A bank with a physical branch in your town will typically offer 0.01% APY on savings; an online bank might offer 4.5% to 5.35% on the same account type. The trade-off is that you cannot walk in and deposit cash or speak to someone in person.
Key Takeaways
- Interest rates change weekly, so the highest rate today may not be the highest next week—check a rate-comparison site before opening any account.
- Online banks consistently offer higher rates than traditional banks because they spend less on branches and staff.
- The account type matters as much as the bank: money market accounts, savings accounts, and CDs all pay different rates at the same institution.
- Some banks offer promotional rates for new customers that drop after a set period, so read the terms before depositing.
- The FDIC insures deposits up to $250,000 per account type per bank, so moving money between banks to chase rates is safe as long as you stay under that limit.
How to compare rates across different account types
A high-yield savings account (HYSA) and a money market account (MMA) both earn interest, but they work differently. A HYSA is simpler: you deposit money, it earns interest, and you can withdraw it anytime without penalty. A money market account lets you write checks or use a debit card, but it may have withdrawal limits and requires a higher minimum deposit. At the same bank, the MMA might pay 0.25% more than the HYSA because of those restrictions.
Certificates of deposit (CDs) lock your money away for a set time—3 months, 6 months, 1 year, 5 years. In exchange, they pay more than savings accounts. A 1-year CD might pay 4.8% while a savings account at the same bank pays 4.5%. If you withdraw early, you lose some or all of the interest you earned, so only use a CD for money you will not need.
Money market funds (sold through investment brokerages) are different from money market accounts (sold by banks). Money market funds are not FDIC-insured and carry a small risk of loss, but they sometimes pay higher rates. Do not confuse the two when comparing.
Why online banks pay more than traditional banks
A traditional bank with branches pays rent, utilities, and salaries for tellers and managers. Those costs come out of the interest it can afford to pay depositors. An online bank has no branches, no tellers, and a smaller staff, so it can pass more of its revenue to you as interest.
Some online banks are subsidiaries of larger traditional banks—Marcus by Goldman Sachs, for example, is owned by Goldman Sachs but operates only online. Others are independent, like Ally or Discover. Both types can offer high rates because their operating costs are low. The trade-off is that you cannot deposit cash in person; you have to transfer money from another bank account or set up direct deposit.
A few traditional banks have created online divisions to compete. Bank of America's online savings account, for instance, pays more than its in-branch account. But the in-branch rate is still lower than what you would get at a pure online bank.
Promotional rates and how long they last
Some banks offer a higher rate for the first 3 to 12 months to attract new customers, then drop the rate to a lower level. For example, a bank might advertise 5.5% APY for the first 6 months, then drop to 4.5% after that. Read the terms carefully before opening the account. The bank's website should state when the promotional period ends and what the standard rate will be.
If you are comfortable moving money between banks, you can chase promotional rates—open an account at Bank A for 6 months at 5.5%, then move the money to Bank B when its promotional rate kicks in. This works as long as you stay under the $250,000 FDIC insurance limit per account type per bank. However, each transfer takes 1 to 3 business days, so you may lose a few days of interest in the move.
Some banks also offer rate bumps if you set up direct deposit or maintain a minimum balance. These are not promotional rates; they are permanent as long as you meet the condition. Check whether the highest rate shown on the comparison site requires direct deposit or a minimum balance you cannot meet.
What to check before opening an account
Before you move money to a new bank, confirm three things: the current APY (not the promotional rate), whether it requires a minimum deposit, and whether it has monthly fees. A bank advertising 5.3% APY might charge a $10 monthly fee if you do not maintain a $10,000 balance. That fee eats into your interest earnings.
Check the bank's website for the full terms and conditions, not just the rate advertised on the comparison site. Look for language about minimum balances, withdrawal limits, and when promotional rates end. If the comparison site shows a rate but the bank's website shows a lower one, the bank's website is correct—use that number.
Confirm the bank is FDIC-insured. Most online banks are, but not all. The FDIC website has a search tool where you can type the bank's name and see whether your deposits are covered. If the bank is not FDIC-insured, your money is at risk if the bank fails.
How FDIC insurance affects where you put your money
The FDIC insures up to $250,000 per account type per bank. This means if you have $250,000 in a savings account at Bank A and $250,000 in a savings account at Bank B, both are fully covered. But if you have $300,000 in one savings account at one bank, only $250,000 is covered.
Different account types are insured separately. You can have $250,000 in a savings account and $250,000 in a CD at the same bank, and both are covered. Joint accounts are also separate: a joint savings account with your spouse is covered up to $250,000, and your individual savings account at the same bank is covered for another $250,000.
If you have more than $250,000 to deposit, split it across multiple banks or multiple account types. This is why some people with large sums open accounts at several online banks—each one is FDIC-insured separately, so the total is protected.
Rate changes and how often to check
Banks change their rates based on what the Federal Reserve does. When the Fed raises its benchmark rate, banks usually raise savings rates within days or weeks. When the Fed cuts rates, banks cut savings rates more slowly—sometimes taking weeks or months. This means the best rate today might not be the best rate in three months.
If you have money in a savings account earning 4.5% and rates jump to 5.5% elsewhere, you are not locked in. You can withdraw your money and move it to the higher-paying bank anytime without penalty (unlike a CD, which charges you for early withdrawal). However, the transfer takes 1 to 3 business days, so you will lose a few days of interest in the move.
Check rates every few months if you have a large sum in savings. If the rate at your current bank drops more than 0.5% below the highest available rate, moving the money is worth the transfer time. If the difference is smaller, the hassle may not be worth it.
Frequently Asked Questions
Can I move my money between banks without losing interest?
You will lose interest for the 1 to 3 business days the transfer takes, but you will not lose any interest that already accrued. The old bank pays interest through the day you withdraw; the new bank starts paying interest the day the money arrives. The gap is unavoidable, but it is usually only a few dollars on most account sizes.
What if I need the money before a CD matures?
You can withdraw it, but the bank will charge an early withdrawal penalty. The penalty is usually 3 to 6 months of interest. For example, if you have a 1-year CD earning 4.8% and you withdraw after 6 months, you might lose 6 months of interest (about 2.4% of your deposit). Always read the CD terms before opening it to know the exact penalty.
Do I need to keep a minimum balance to earn the advertised rate?
Many banks do, and some do not. Check the bank's terms page. If a minimum balance is required and you drop below it, the bank may lower your rate or charge a monthly fee. Some banks waive the minimum if you set up direct deposit, so ask about that option.
Is it safe to move money between banks to chase higher rates?
Yes, as long as each bank is FDIC-insured and you stay under $250,000 per account type per bank. The transfer itself is safe—your money is protected during the move. The only cost is the interest you lose during the 1 to 3 business days the transfer takes.
What happens to my rate if the Federal Reserve cuts interest rates?
Your rate will drop, but not immediately. Banks usually cut savings rates within a few weeks of a Fed cut, but the timing varies. Some banks cut quickly; others wait longer. If you want to lock in a rate before a cut, a CD is your best option—the rate is fixed for the entire term.
