The banks and credit unions offering the best rates today
The highest interest savings accounts are almost always at online banks and credit unions, not at the brick-and-mortar banks most people use for checking. Online banks like Marcus, Ally, and American Express Personal Savings typically offer rates between 4.0% and 5.3% annual percentage yield (APY), while traditional banks often pay 0.01% to 0.5%. Credit unions sometimes match or beat online bank rates, but only for members who meet their specific requirements.
Rates change weekly, sometimes daily, so there is no permanent "highest" — but the gap between online and traditional banks stays wide. A $10,000 deposit earning 4.5% APY generates about $450 per year in interest. The same deposit at a traditional bank earning 0.1% generates $10. That difference compounds if you leave the money untouched.
The catch is that the highest-rate accounts usually come with restrictions: minimum deposits, account requirements, or membership fees. Some require you to set up direct deposit. Others limit how many withdrawals you can make per month. Reading the fine print before you open an account saves frustration later.
Key Takeaways
- Online banks and credit unions consistently offer rates 10 to 50 times higher than traditional banks, though rates shift weekly based on Federal Reserve policy.
- The highest rates often require a minimum deposit of $500 to $25,000, direct deposit setup, or membership in a credit union with specific income or location requirements.
- You can compare current rates on sites like Bankrate, DepositAccounts, or NerdWallet, which update daily and let you filter by minimum deposit and account type.
- Moving money between accounts takes one to three business days, so switching to a higher rate does not happen instantly, but the interest difference pays for itself within months.
How online banks keep rates higher than traditional banks
Online banks have lower overhead costs than branches do. They do not pay rent on storefronts, do not staff tellers, and do not maintain ATM networks. That savings gets passed to depositors as higher interest rates. They compete on rate alone because they cannot offer the convenience of walking into a physical location.
Traditional banks use deposits to fund loans — mortgages, car loans, credit cards. They keep interest rates low on savings accounts because they profit more from lending the money out at higher rates. Online banks do the same thing, but they operate on thinner margins and pass more of the profit to savers.
Credit unions are member-owned cooperatives, so they theoretically return profits to members. In practice, some credit unions offer excellent rates and some do not. The rate depends on the union's size, lending strategy, and how much competition they face in their region.
What to check before opening an account
Start by looking at the annual percentage yield (APY), not just the interest rate. APY includes compounding, so it is the real number that matters. A bank advertising "4.5% APY" will pay you exactly that much per year if you leave the money untouched.
Check the minimum deposit to open the account. Some banks require $0; others require $500, $1,000, or $25,000. If you have $2,000 to deposit and a bank requires $25,000 to earn the advertised rate, you will earn a lower rate on your actual balance. Read the terms carefully — the fine print often says "earn this rate only on balances of $25,000 or more."
Look for monthly fees. Most high-rate savings accounts have no monthly maintenance fee, but some charge $5 to $10 per month if your balance drops below a threshold. A $5 monthly fee erases years of interest gains on a small deposit.
Confirm whether the bank requires direct deposit to earn the top rate. Some banks offer one rate if you set up direct deposit and a lower rate if you do not. If you are self-employed or do not receive regular paychecks, this matters.
Credit unions versus online banks
Credit unions sometimes offer rates as high as or higher than online banks, but membership requirements vary widely. Some credit unions are open to anyone in a geographic area. Others require you to work for a specific employer, belong to an organization, or have a family member who is already a member. A few require you to live in a certain state or county.
To find credit unions you might join, search the CO-OP Network or Alliant Credit Union's directory. Many credit unions also participate in shared branching networks, which means you can conduct transactions at other credit unions' branches even if you do not live near your own bank.
The tradeoff is that credit unions often have lower ATM networks and fewer online features than online banks. If you need to withdraw cash frequently or want a polished mobile app, an online bank might feel smoother. If you want a personal relationship with a teller or need to handle complex transactions, a credit union with a physical branch might serve you better.
How to compare rates across banks
Do not rely on a single bank's website to find the highest rate. Banks update their rates on their own schedules, and comparison sites sometimes lag by a day or two. Use at least two sources: Bankrate, DepositAccounts, and NerdWallet all update daily and let you filter by minimum deposit, account type, and region.
When you find a rate you like, visit the bank's website directly to confirm it matches what the comparison site shows. Rates can vary by a few basis points (hundredths of a percent) depending on how much you deposit, so verify the exact terms before you open an account.
Keep in mind that the highest rate today might not be the highest rate next month. The Federal Reserve sets a target interest rate, and banks adjust their savings rates in response. When the Fed raises rates, savings rates usually rise within days or weeks. When the Fed cuts rates, banks cut savings rates quickly too. If you lock in a high rate and the Fed cuts rates later, your rate usually stays the same — banks do not lower rates on existing accounts.
Moving money to a higher-rate account
Transferring money between banks takes one to three business days. You can initiate the transfer online through your current bank (usually under "Transfer" or "Move Money") or through the new bank's website. Most banks offer both ACH transfers (free, slower) and wire transfers (faster, sometimes with a fee).
You do not have to close your old account immediately. Many people keep a small balance in their traditional bank for convenience and move the bulk of their savings to a high-rate account. This way you have cash available at an ATM if you need it, but most of your money earns a real return.
If you have a large deposit, consider splitting it across multiple banks. The Federal Deposit Insurance Corporation (FDIC) insures up to $250,000 per depositor per bank. If you have $500,000 in savings, putting it all at one bank leaves $250,000 uninsured. Splitting it between two banks keeps all of it protected.
Frequently Asked Questions
Do I lose money if I move my savings to a different bank?
No. Transferring money between banks does not cost you anything (unless you pay for a wire transfer, which is optional). The money sits in your old account until the transfer clears, then appears in your new account. You earn interest at your old bank until the money leaves and at your new bank once it arrives.
What if the rate drops after I open the account?
Banks can lower rates on new deposits at any time, but they usually cannot lower the rate on money you already have in the account. Your rate stays locked in. However, read the account terms — a few banks reserve the right to lower rates on existing balances with notice, though this is rare.
Is my money safe at an online bank?
Yes, as long as the bank is FDIC-insured. Check the bank's website or the FDIC's bank search tool to confirm. Online banks are regulated the same way as traditional banks. The only difference is that you cannot walk into a branch, but you can handle everything online or by phone.
Can I withdraw money whenever I want?
Yes. Savings accounts have no withdrawal limits anymore — the Federal Reserve removed that rule in 2020. You can withdraw as much as you want, whenever you want. The only catch is that transfers between banks take one to three business days, so you cannot access the money instantly if it is at a different bank than where you need it.
What happens if a bank fails?
The FDIC takes over and pays you up to $250,000 of your deposit. This has happened fewer than 20 times since 2008, and depositors have always been paid in full up to the insurance limit. Keeping your money at an FDIC-insured bank is safer than keeping cash at home.
