Start with the interest rate, but check what it actually means

The annual percentage yield (APY) is the number banks advertise first, and it matters — but only if you understand what you're looking at. APY tells you what percentage of your balance you'll earn in interest over a year, and it accounts for compounding (interest earning interest). A 4.50% APY is not the same across all banks, because the rate can change at any time, and some banks may provide it only for new money or for a limited period.

Before you open an account, check whether the rate is a promotional rate that drops after a few months, or a standard rate that applies to all balances. Read the fine print on the bank's website — it will say something like "current rate" or "as of [date]". Rates change weekly, sometimes daily, so a rate you see today may be different next week. If you're comparing banks, compare them on the same day.

The difference between 4.25% and 4.75% sounds small, but on $10,000 it's about $50 per year. On $50,000 it's $250. The larger your balance, the more the rate matters.

Key Takeaways

  • High-yield savings accounts at online banks typically offer APY rates between 4% and 5%, while traditional brick-and-mortar banks often offer less than 1%.
  • Check whether the rate is promotional (temporary) or standard, because promotional rates usually drop after three to six months.
  • FDIC insurance protects up to $250,000 per depositor per bank, so if you have more than that, you'll need accounts at multiple banks.
  • Monthly fees, minimum balance requirements, and withdrawal limits vary widely — some accounts have none, while others charge $5 to $10 per month or require $25,000 minimums.
  • You don't need a checking account at the same bank to open a savings account, and linking accounts for transfers is optional.

Understand FDIC insurance limits before you deposit large amounts

The Federal Deposit Insurance Corporation (FDIC) insures deposits at member banks up to $250,000 per depositor per bank. That means if you have $300,000 and put it all in one high-yield savings account, only $250,000 is protected if the bank fails. The other $50,000 is not covered.

If you have more than $250,000 to save, you have two options: open accounts at different banks (each account gets its own $250,000 of coverage), or use a service like InvestorDepositNetwork or Promontory Interbank Network, which splits your money across multiple FDIC-insured banks automatically. Most people don't need to worry about this, but if you do, it's worth setting up before you deposit the money.

Check that the bank you're considering is FDIC-insured by searching the FDIC's Bank Find tool on their website. All major online banks are, but it's worth confirming.

Compare fees and minimum balance requirements across your top choices

Some high-yield savings accounts charge monthly maintenance fees ($5 to $10), while others charge nothing. Some require a minimum opening balance ($0 to $25,000), and some don't. These differences add up, especially if you're starting with a small balance or if you plan to withdraw money regularly.

Make a list of the accounts you're considering and write down: the APY, whether it's promotional or standard, the monthly fee (if any), the minimum opening balance, the minimum balance to earn the full rate, and whether there are limits on how many times you can withdraw per month. Most high-yield savings accounts have no withdrawal limits anymore, but some older accounts or accounts at smaller banks still do.

If you're starting with less than $1,000, a $0 minimum account at an online bank like Marcus, Ally, or Capital One 360 makes more sense than an account that requires $25,000. If you have $50,000 or more, you can afford to be pickier about the rate, because the difference in earnings will outweigh small fees.

Decide whether you need easy access to your money

High-yield savings accounts are designed for money you're saving but might need within a few months or a year — not money you're saving for retirement (that's what IRAs are for) and not money you need to spend this week (that's what checking accounts are for). Before you open an account, think about when you might need this money.

If you might need it within a month, a high-yield savings account is fine — you can transfer money to your checking account in one to three business days at most banks. If you need it today or tomorrow, keep it in your checking account instead. If you won't need it for five years or more, consider a certificate of deposit (CD), which locks your money away for a set time but usually pays a higher rate.

Some banks let you link your high-yield savings account to a checking account at the same bank for faster transfers. Others require you to transfer through an external account, which takes longer. If speed matters to you, ask about this before you open the account.

Online banks usually offer higher rates than traditional banks

Online-only banks (Marcus, Ally, Capital One 360, American Express Personal Savings) typically offer APY rates between 4% and 5%, while traditional banks with physical branches usually offer less than 1%. The reason is simple: online banks have lower overhead costs, so they can pass the savings to you in the form of higher rates.

The tradeoff is that you can't walk into a branch to deposit cash or talk to someone in person. Most online banks let you deposit checks by taking a photo with your phone, and they reimburse ATM fees if you use an out-of-network machine. If you rarely deposit cash and don't need in-person service, an online bank usually makes sense.

If you prefer to bank in person or you deposit cash regularly, look for a credit union or a regional bank that offers a high-yield savings account. The rate will be lower than online banks, but it may be higher than the national average for traditional banks.

Check the bank's reputation and customer service options before you commit

Read recent reviews on sites like Trustpilot, Google Reviews, or the Better Business Bureau to see what customers say about deposits, withdrawals, and customer service. Look for patterns — if dozens of people say transfers take longer than promised or customer service is hard to reach, that's a real problem. A few negative reviews are normal; widespread complaints are a red flag.

Test the bank's customer service before you open an account. Call their phone number or use their chat feature and ask a question about how the account works. See how long it takes to get an answer and whether the person actually helps you. If you can't reach anyone or the answer is vague, that's what you can expect later if something goes wrong.

Also check whether the bank offers customer service by phone, email, chat, or only through an app. If you prefer to talk to a human, make sure that option exists.

Open the account and set up automatic deposits if you can

Once you've chosen a bank, opening an account usually takes 10 to 15 minutes online. You'll need your Social Security number, a government ID, your current address, and a way to fund the account (a transfer from another bank account, or a check deposit by photo). Some banks let you open an account with $0 and fund it later; others require a minimum opening deposit.

After the account is open, consider setting up automatic transfers from your checking account. Even $50 or $100 per week adds up, and automatic transfers mean you don't have to remember to move the money yourself. Most banks let you set this up in their app or online banking portal.

Keep the account open even if you're not using it actively. Closing accounts can affect your credit score slightly, and you might want to move money back into the account later if rates drop at other banks or if you have extra cash.

Frequently Asked Questions

Can I move my money out whenever I want, or is it locked away?

You can move your money out whenever you want — there are no early withdrawal penalties. Transfers to another bank account take one to three business days. If you need the money faster, transfer it to a checking account at the same bank, which is usually instant or next-day.

What happens if the interest rate drops after I open the account?

Your money stays in the account and earns the new (lower) rate. You're not locked into the rate you saw when you opened it. If rates drop significantly, you can move your money to a different bank, but there's no penalty for doing so.

Do I need a checking account at the same bank to open a savings account?

No. You can open a high-yield savings account at any bank without having a checking account there. You can transfer money in and out using your existing checking account at a different bank.

Is my money safe in an online bank?

Yes, as long as the bank is FDIC-insured (which all major online banks are). FDIC insurance protects your money the same way it protects money at a traditional bank. You can verify FDIC insurance status using the FDIC's Bank Find tool.

What's the difference between a high-yield savings account and a money market account?

Both earn interest and are FDIC-insured, but money market accounts sometimes come with a debit card or checkbook, and they may have higher minimum balances. High-yield savings accounts are simpler and usually have lower minimums. For most people, a high-yield savings account is the better choice.
