What determines the rate your bank pays you

The rate a bank pays on your savings account depends on two things: what the Federal Reserve has set as its benchmark rate, and how much of that rate the bank decides to pass on to you. Right now, banks can offer anywhere from nearly 0% to over 5% on savings accounts, even though they're all operating under the same Federal Reserve environment. The difference is how much profit margin each bank wants to keep.

When the Federal Reserve raises or lowers its benchmark rate, banks don't automatically adjust your rate on the same day. Some move within hours. Others wait weeks or months. A few never move at all—they'll keep your rate flat even when the Fed raises rates, because they're betting you won't notice or won't switch accounts. This is why two banks offering "high-yield" savings can have rates that differ by a full percentage point.

The second factor is the bank's funding model. Online-only banks like Marcus, Ally, and Wealthfront have lower overhead costs than a bank with physical branches. They pass some of that savings to you through higher rates. Banks with thousands of branches and expensive real estate have higher costs, so they typically offer lower rates even when they call their accounts "high-yield."

Key Takeaways

  • Savings account rates vary from under 1% to over 5% depending on the bank, even when the Federal Reserve rate is the same for all of them.
  • Online banks usually offer higher rates than traditional banks because they have lower operating costs and no branch network to maintain.
  • The rate you see advertised is not may provide to stay the same—banks can lower it at any time, though they must give you notice.
  • The highest rates right now are found by checking current offers from online banks directly, not by relying on comparison sites that may be outdated within days.
  • A difference of 1% on a $10,000 account means $100 per year, so comparing rates before you deposit is worth the five minutes it takes.

How to find the current highest rates

The rates you see on comparison websites are often a day or two old. Savings account rates move constantly, especially when the Federal Reserve is changing its benchmark. The most accurate way to find the highest rate is to visit the banks' websites directly and look at what they're advertising on their homepage or savings account page.

Start with the banks that consistently rank at the top: Marcus (owned by Goldman Sachs), Ally Bank, American Express Personal Savings, Wealthfront, and Vanguard. These five have historically offered rates within a fraction of a percentage point of each other. Check each one's website, note the rate and any conditions (some require a minimum deposit, though most don't anymore), and compare the actual numbers side by side.

If you have $100,000 or more, also check rates at credit unions through CO-OP or Allpoint networks, and at banks like Connexus or Pentagon Federal Credit Union. Credit unions sometimes offer rates competitive with online banks, and a few occasionally exceed them for members who meet certain conditions like direct deposit or monthly transfers.

The difference between advertised rates and what you actually earn

The rate a bank advertises is called the Annual Percentage Yield, or APY. This is the rate you'll actually earn if you leave your money untouched for a full year. It includes the effect of compounding—the bank paying interest on the interest you've already earned. Most savings accounts compound daily, which means the bank calculates interest every single day and adds it to your balance.

The advertised APY assumes the rate stays the same for the entire year. In reality, banks change rates frequently. If you open an account at 5.35% APY and the bank drops it to 4.50% after three months, you'll earn the higher rate only on the money that sat in the account during those first three months. Your annual earnings will be less than 5.35% of your balance.

This is why the timing of when you deposit matters. If you're moving money from a checking account or another savings account, move it when rates are high, not when you happen to have the cash available. A rate drop can happen within weeks of the Federal Reserve signaling a change in direction.

Why rates change and how often to expect it

Banks adjust savings rates in response to two signals: changes in the Federal Reserve's benchmark rate, and changes in how much competition they're facing for deposits. When the Fed raises its rate, banks have more incentive to offer higher savings rates because they can earn more from lending out the money you deposit. When the Fed lowers its rate, banks lower savings rates because they're earning less.

But the Fed's moves aren't the only reason rates change. If a bank is trying to attract more deposits—maybe because they've made a lot of loans and need more cash on hand—they'll raise their rate to pull in new customers. If they have plenty of deposits already, they'll lower the rate to reduce their costs. This is why you sometimes see one bank's rate jump while others stay flat.

The Federal Reserve typically meets eight times per year to decide on its benchmark rate. Rates tend to shift most noticeably in the weeks after those meetings. Between meetings, changes are usually smaller. If you're watching rates closely, checking once a week is enough; checking daily will just frustrate you.

Comparing rates across different account types

A standard savings account and a money market account are usually offered by the same bank at similar rates. The main difference is that a money market account often comes with a debit card and check-writing ability, while a savings account limits you to six transfers per month (though this rule is less strictly enforced than it used to be). If you need to access your money frequently, a money market account might be more convenient, but the rate will be nearly identical.

Certificates of Deposit, or CDs, lock your money away for a set period—usually three months to five years—in exchange for a may provide rate. Right now, CD rates are sometimes higher than savings account rates, especially for longer terms. The tradeoff is that you can't touch the money without paying a penalty. If you know you won't need the money for a year or more, a CD might earn you more. If you might need it sooner, a savings account's flexibility is worth the slightly lower rate.

Money market funds (offered by investment firms) and Treasury bills (short-term government debt) can also earn you interest, but they're not the same as a savings account. They carry different risks and tax treatment. For the purposes of comparing where to park cash you need to keep safe and accessible, stick with savings accounts and CDs at banks or credit unions.

What happens to your rate if the Federal Reserve cuts rates

When the Federal Reserve lowers its benchmark rate, banks lower savings rates within days or weeks. The drop is usually proportional—if the Fed cuts by 0.5%, expect savings rates to fall by roughly 0.5% as well, though some banks move faster or further than others. A bank that was paying 5.35% might drop to 4.85% within a week of a Fed cut.

You have no control over this. The bank doesn't need your permission to lower your rate, though they are required by law to notify you before the change takes effect. The notification usually comes via email or a notice in your online banking portal. You'll have a window of time (usually 30 days) to close the account and move your money elsewhere if you don't like the new rate.

This is why locking in a high rate with a CD makes sense if you believe rates are about to fall. If you think rates will stay high or go higher, a savings account's flexibility is worth more than the slightly higher CD rate.

How FDIC insurance affects your choice of bank

Every bank offering savings accounts in the United States is required to carry FDIC insurance. This means if the bank fails, the government will reimburse you up to $250,000 per account type per bank. A savings account and a money market account at the same bank are insured separately, so you could have $250,000 in each and be fully covered.

This protection is automatic—you don't have to do anything to get it. It applies whether the bank is online-only or has branches. It applies whether the rate is 0.01% or 5.35%. Because of this insurance, the safety of your money doesn't depend on which bank you choose. You can confidently move your money to whichever bank is offering the highest rate without worrying about the bank's stability.

If you have more than $250,000 to save, you can open accounts at multiple banks to keep everything insured. Some people open accounts at five or six different banks specifically to spread their deposits across the insurance limit at each one.

Frequently Asked Questions

Do I need a minimum deposit to open a high-yield savings account?

Most online banks no longer require a minimum deposit. Marcus, Ally, American Express, and Wealthfront all allow you to open an account with $1 or $0. Some credit unions and smaller online banks may require $100 or $500, but the major players have eliminated minimums to compete for customers.

Can a bank lower my rate without warning?

A bank can lower your rate, but they must give you advance notice—usually 30 days. You'll receive notification via email or your online banking portal. You have the right to close the account and move your money before the new rate takes effect. The bank cannot lower your rate retroactively or without telling you first.

Is a 5% savings account rate a scam?

No, but it's temporary. When the Federal Reserve's benchmark rate is high, legitimate banks do offer rates above 5%. These rates are real, insured by the FDIC, and available to anyone. However, they won't last forever. When the Fed lowers its rate, bank savings rates will fall too. Lock in a high rate with a CD if you want to may provide it for a specific period.

Should I move my money every time a bank raises its rate?

Only if the difference is significant enough to be worth your time. Moving $5,000 from a 4.5% account to a 5.0% account earns you an extra $25 per year. If it takes you an hour to research, open the new account, and transfer the money, that's $25 per hour. For larger balances, the math works better. For $50,000, the same move earns you $250 per year.

What's the difference between APY and APR on a savings account?

APY (Annual Percentage Yield) is what you earn on savings; it includes compounding. APR (Annual Percentage Rate) is what you pay on debt; it doesn't include compounding. For savings accounts, always look at the APY. That's the real number that tells you how much you'll earn.
