Savings account interest rates vary by bank and change weekly, so there's no single answer

The interest rate on a savings account depends entirely on which bank you choose and what type of account you open. Banks set their own rates, and those rates shift constantly based on what the Federal Reserve does with its benchmark rate. Right now, rates range from nearly 0% at some traditional banks to around 4% to 5% at online banks and credit unions—but that spread changes every few weeks.

The rate you see advertised is the Annual Percentage Yield (APY), which is what you'll actually earn over a year if you leave the money untouched. That's different from the interest rate itself, because APY includes the effect of compounding—the bank paying interest on the interest you've already earned. The more often interest compounds (daily is common), the higher your APY will be compared to the stated rate.

Your actual earnings depend on three things: the APY the bank offers, how much money you deposit, and how long you leave it there. A $10,000 deposit at 4.5% APY earns about $450 per year. The same deposit at 0.01% APY earns $1. That difference matters, especially if you're parking money you won't need for months or years.

Key Takeaways

  • Online banks and credit unions typically offer APY between 4% and 5%, while traditional brick-and-mortar banks often offer 0.01% to 0.5%.
  • The APY you see is the annual return including compounding, so it's the number to compare across banks, not the base interest rate.
  • Rates change weekly or monthly as the Federal Reserve adjusts its benchmark rate, so the APY you see today may be lower or higher in three months.
  • High-yield savings accounts at online banks have no monthly fees and no minimum balance requirements at most providers, making them accessible to anyone.
  • Money market accounts and certificates of deposit (CDs) may offer higher rates than savings accounts, but they restrict how often you can withdraw.

Why rates differ so much between banks

Traditional banks with physical branches—Chase, Bank of America, Wells Fargo—typically offer savings rates between 0.01% and 0.5% because they have high overhead costs. They pay for buildings, staff, and advertising. They also rely on deposits to fund loans, so they don't need to compete aggressively on savings rates to attract money.

Online banks like Marcus, Ally, and American Express Personal Savings have no branches and minimal staff, so their costs are much lower. They pass that savings to depositors by offering rates between 4% and 5%. They still make money by lending out deposits at higher rates, but they can afford to pay you more because they spend less to operate.

Credit unions are member-owned cooperatives, not profit-driven corporations, so they often offer competitive rates similar to online banks. Some credit unions offer 4% to 5% APY on savings accounts, though you typically need to be a member to open an account—membership usually requires living or working in a specific area or belonging to a certain employer or organization.

How the Federal Reserve affects what you earn

The Federal Reserve sets a benchmark interest rate that influences what banks charge borrowers and what they pay savers. When the Fed raises its rate, banks usually raise savings rates within weeks. When the Fed cuts its rate, savings rates fall shortly after. This is why your APY can change multiple times per year.

The Fed has raised rates significantly since 2022, which is why savings accounts now offer 4% to 5% instead of the 0.01% they offered in 2021. If the Fed cuts rates in the future, those high yields will fall. There's no way to lock in a current rate on a regular savings account—the bank can change it anytime. (Certificates of deposit, or CDs, do lock in a rate for a set period, but you can't withdraw the money early without a penalty.)

Comparing rates across banks takes minutes

You don't need to visit each bank's website individually. Comparison sites like Bankrate, DepositAccounts, and NerdWallet update savings rates daily and let you filter by account type, minimum balance, and whether you need a physical location nearby. You can see which banks offer the highest APY and whether they charge monthly fees or require a minimum deposit.

When you compare, look at three things: the APY itself, any monthly maintenance fees, and the minimum balance to open the account. A bank offering 4.75% APY with a $25 monthly fee is worse than one offering 4.5% with no fee. Most online banks have no monthly fees and no minimum balance, so the APY is the main difference between them.

Once you've chosen a bank, opening an account takes 10 to 15 minutes online. You'll need your Social Security number, a government ID, and a way to fund the account—usually a transfer from another bank account. Money typically arrives within one to three business days.

What happens to your interest if rates drop

If you open a savings account at 4.5% APY and the Federal Reserve cuts rates, your bank will lower your APY too—usually within a few weeks. You won't lose the money you've already earned, but new interest will accrue at the lower rate. There's no penalty for this; it's how savings accounts work.

If you want to protect yourself against rate cuts, a certificate of deposit (CD) locks in a rate for a set term—typically three months to five years. If you open a one-year CD at 4.5%, you'll earn 4.5% for the full year even if rates fall to 2%. The tradeoff is that you can't withdraw the money early without paying a penalty (usually a few months' worth of interest). CDs make sense if you know you won't need the money for a specific period and want certainty about your return.

How compounding affects your total earnings

Interest compounds when the bank adds earned interest back into your account, and then pays interest on that larger balance. If you deposit $10,000 at 4.5% APY with daily compounding, the bank calculates interest every day on your current balance—which grows slightly each day as interest is added. Over a year, daily compounding means you earn about $460 instead of $450, because you're earning interest on the interest.

The difference between daily and monthly compounding is small on a savings account, but it adds up over time and on larger balances. Most online banks compound daily, which is why they advertise APY rather than just the interest rate—the APY number already includes the compounding effect and is what you'll actually earn.

Frequently Asked Questions

Can I move my money between savings accounts if rates change?

Yes. You can withdraw from one savings account and deposit into another at any time with no penalty. Transfers between banks take one to three business days. If you find a bank offering a significantly higher rate, moving your money costs nothing except the time to set up the new account.

Do I pay taxes on savings account interest?

Yes. Interest earned on a savings account is taxable income. Banks send you a 1099-INT form each January if you earned $10 or more in interest during the year. You report this on your tax return. The higher your APY and balance, the more tax you'll owe on the earnings.

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

A money market account usually offers a higher APY than a savings account but limits how many withdrawals you can make per month—often three to six. Savings accounts typically allow unlimited withdrawals. Both are FDIC-insured up to $250,000 per depositor per bank, so your money is protected either way.

Will my savings account rate ever go back to 5% or higher?

Rates depend on what the Federal Reserve does, which depends on inflation and economic conditions. If inflation rises again and the Fed raises rates, savings rates could climb above 5%. If inflation stays low and the Fed cuts rates, savings rates will fall. No one can predict this with certainty, which is why CDs exist—to lock in a rate if you think rates will fall.

Is it worth moving $500 to a high-yield savings account?

At 4.5% APY, $500 earns about $22.50 per year. That's not much, but it's better than the $0.05 you'd earn at a traditional bank. If you're already opening a savings account anyway, choosing a high-yield option costs nothing and takes the same time. The real benefit appears when you have larger balances or leave money there for years.
