Interest rates vary by bank and change weekly, so there is no single "best" bank for everyone
The bank with the highest rate today may not have it next week. Interest rates on savings accounts, money market accounts, and CDs move based on what the Federal Reserve does and what each bank decides to offer. A bank offering 4.5% this month might drop to 4.2% the next, while a competitor raises theirs to 4.75%.
The highest rates are almost never at the big national banks you see on every corner. Banks like Chase, Bank of America, and Wells Fargo typically offer rates well below 1% on savings accounts because they rely on branch networks and other services to attract customers. Online banks and credit unions, which have lower overhead costs, pass those savings to depositors through higher rates.
Your best move is to check current rates across multiple banks before you deposit money, then check again before you move money elsewhere. Rates change frequently enough that a bank ranked first one month can slip to fifth the next.
Key Takeaways
- Online banks and credit unions typically offer rates two to four times higher than traditional brick-and-mortar banks.
- Rates change weekly or even daily, so comparing banks on the day you plan to deposit matters more than finding a "best" bank in general.
- The highest advertised rate is not always the best choice if the bank has withdrawal limits, high minimum deposits, or fees that eat into your earnings.
- Money market accounts and CDs often pay more than regular savings accounts at the same bank, but lock your money away or limit how often you can withdraw.
- Credit unions may offer competitive rates and require membership, which sometimes means opening a checking account or meeting other conditions.
Where to find current rates and compare them
Use a rate-tracking website to see what multiple banks are paying on the same day. Sites like Bankrate, DepositAccounts, and NerdWallet pull rates from banks and update them regularly. These sites let you filter by account type (savings, money market, CD), term length (for CDs), and minimum deposit amount.
When you find a rate that interests you, go directly to that bank's website to confirm the rate is still current. Websites sometimes lag by a day or two, and a rate can change between when you see it listed and when you click through.
Check the fine print for what happens after the promotional period ends. Some banks offer a high rate for the first three months, then drop it sharply. Others maintain competitive rates across all customers. The rate you see is the one you will earn, but only if you understand when it changes.
Online banks versus credit unions versus traditional banks
Online banks (like Marcus, Ally, and Discover) have no physical branches, which means lower costs. They pass this to customers through higher rates. Most online banks currently pay between 4% and 5.35% on savings accounts, though this varies. They typically have no monthly fees and no minimum deposit requirements, though some require a small opening deposit.
Credit unions are member-owned cooperatives that often pay rates competitive with online banks. You must join to use them, which sometimes requires living or working in a certain area, belonging to an employer, or opening a checking account. Once you join, rates are often as good as or better than online banks. Credit unions also tend to have more lenient policies on overdrafts and late payments.
Traditional banks (Chase, Bank of America, Wells Fargo, Citibank) offer convenience through branches and ATMs, but their savings rates are typically below 0.5%. You pay for that convenience through lower returns on your money. If you need frequent in-person banking, the rate difference may be worth it. If you are depositing money and leaving it alone, an online bank or credit union will earn you significantly more.
What to check beyond the advertised rate
A high rate means nothing if the bank charges fees that eat into your earnings. Look for accounts with no monthly maintenance fees, no minimum balance requirements, and no fees for transfers or withdrawals. Some banks charge you to move money out, which defeats the purpose of chasing a high rate.
Check how often interest is compounded and credited to your account. Most banks compound daily and credit monthly, which is standard. Some credit quarterly or annually, which means you earn less. The difference is small on smaller balances but adds up on larger ones.
Confirm the bank is FDIC-insured (for banks) or NCUA-insured (for credit unions). This protects your money up to $250,000 if the bank fails. Nearly all legitimate banks and credit unions carry this insurance, but it is worth verifying before you deposit a large sum.
Read the terms on any promotional rate. If a bank offers 5% for the first three months, what rate do you get after that? Some banks lock you into a much lower rate once the promotion ends, making the initial offer less attractive than it looks.
Money market accounts and CDs pay more, but with tradeoffs
Money market accounts often pay slightly more than savings accounts at the same bank because they require a higher minimum deposit (often $2,500 to $10,000) and limit how many times you can withdraw per month. You get check-writing privileges and a debit card, but frequent withdrawals can trigger fees or drop your rate.
Certificates of Deposit (CDs) lock your money away for a set term—typically three months to five years—in exchange for a may provide rate. A one-year CD might pay 4.8%, while a five-year CD pays 5.2%. You cannot touch the money without paying an early withdrawal penalty, usually equal to several months of interest. CDs make sense if you know you will not need the money for a specific period and want to lock in a rate before it drops.
High-yield savings accounts are the middle ground: they pay nearly as much as money market accounts, have no withdrawal limits, and require no minimum deposit at most online banks. If you want the highest rate with the most flexibility, a high-yield savings account at an online bank is usually the best choice.
How to move money between banks without losing interest
When you find a bank with a better rate, you can move your money without penalty. Most banks offer free transfers between accounts at different institutions using ACH (Automated Clearing House), which takes three to five business days. Some online banks reimburse wire transfer fees if you are moving a large balance.
Interest accrues daily, so you earn interest right up until the day you withdraw. When you deposit at the new bank, interest starts accruing immediately. You do not lose a day of interest by switching, though the three- to five-day transfer window means you will miss interest on that money while it is in transit.
If you are moving a large balance and rates are rising, consider splitting the move across two or three banks to lock in different rates. If rates are falling, move everything at once to the highest-paying bank before rates drop further.
Frequently Asked Questions
Do I need a minimum deposit to open a high-yield savings account?
Most online banks require no minimum deposit or only $1 to $25 to open an account. Some require $500 to $2,500 to earn the advertised rate, though this is less common. Check the bank's website for the specific requirement before you open an account.
What happens to my interest rate if the Federal Reserve cuts rates?
Banks typically lower their rates within days or weeks of a Federal Reserve cut, though they are not required to. Your rate will drop, but the exact timing and amount depend on the bank. This is why locking in a CD at a high rate can be smart if you think rates are about to fall.
Can I earn interest on money I need to access quickly?
Yes. High-yield savings accounts have no withdrawal limits and no penalties for taking your money out. You earn interest while the money sits there, and you can move it to your checking account in one to three business days whenever you need it.
Is my money safe at an online bank?
Yes, if the bank is FDIC-insured. Check the bank's website for the FDIC insurance logo or search the FDIC's bank finder tool. Your deposits are protected up to $250,000 per account type, the same as at any traditional bank.
Should I split my savings across multiple banks to earn higher rates?
If you have more than $250,000, splitting across banks makes sense for FDIC insurance protection. If you have less, keeping everything at one high-rate bank is simpler. Some people split across two or three banks to diversify or to lock in different CD rates, but this adds complexity for minimal gain on smaller balances.
