The interest rate on a savings account is the percentage of your balance that the bank pays you each year for letting them use your money

When you deposit money into a savings account, the bank lends that money to other customers as mortgages, car loans, and business loans. In exchange, the bank pays you interest—a small percentage of your balance, calculated and added to your account on a schedule the bank sets (usually monthly or daily). That percentage is your interest rate.

The rate you receive depends on three things: the current economic environment (set largely by the Federal Reserve), the bank's own costs and competition, and the type of account you open. A regular savings account at a large national bank might pay 0.01% annually, while a high-yield savings account at an online bank might pay 4.5% to 5.35%—the exact figure changes weekly as banks adjust their rates in response to market conditions.

Key Takeaways

  • Interest rates on savings accounts vary from under 0.01% at traditional banks to over 5% at online banks, and they change frequently based on Federal Reserve policy.
  • High-yield savings accounts almost always pay more than regular savings accounts at the same bank, even though both are equally safe.
  • Your actual earnings depend on your balance, the rate offered, and how often interest is compounded—usually daily or monthly.
  • The Federal Reserve's benchmark rate influences what banks offer, so rates rise and fall over time rather than staying fixed.

How banks decide what rate to offer you

Banks set savings rates based on what the Federal Reserve charges them to borrow money. When the Fed raises its benchmark rate, banks eventually raise the rates they offer on savings accounts. When the Fed lowers rates, banks lower what they pay you. This lag can be weeks or months, and banks don't always pass along the full change.

Competition also matters. Online banks with lower overhead costs can afford to pay higher rates than brick-and-mortar banks. A bank in a competitive market may raise its rate to attract deposits. A bank with a captive customer base (people who have their paycheck deposited there, for example) may keep rates low because customers won't leave.

The type of account you choose also affects the rate. A regular savings account typically earns less than a money market account or a certificate of deposit (CD) with the same bank, because you can withdraw from a savings account anytime without penalty, while a CD locks your money for a set term.

The difference between APY and interest rate

Banks advertise two related but different numbers: the interest rate and the annual percentage yield (APY). The interest rate is the raw percentage. The APY includes the effect of compounding—the process of earning interest on your interest.

If a bank compounds interest daily, you earn a tiny bit of interest each day, and the next day you earn interest on that interest too. Over a year, compounding adds up. A savings account with a 4.5% interest rate compounded daily will deliver an APY of approximately 4.6% because of compounding. The APY is always equal to or higher than the stated rate, and it's the number that matters for comparing accounts.

Banks are required to disclose the APY prominently, so when you're shopping for accounts, compare the APY figures, not the interest rates.

Why rates change and what that means for your money

Savings rates are not fixed. They move up and down based on Federal Reserve decisions, which happen roughly every six weeks. When the Fed raises rates, banks eventually raise what they pay on savings accounts—sometimes within days, sometimes over weeks. When the Fed cuts rates, banks cut what they pay you, often more quickly than they raised it.

This means the rate you lock in today may be higher or lower in three months. Some people move their money between banks chasing the highest rate. Others set it and leave it. Neither approach is wrong; it depends on how much time you want to spend managing the account and how much the difference matters to your balance.

If you have a large emergency fund or are saving for a goal a year or more away, even a 1% difference in APY adds up. On $10,000, the difference between 0.01% and 4.5% is roughly $450 per year. On $50,000, it's $2,250. On smaller balances, the difference is smaller, but it's still real money you're leaving on the table by staying with a low-rate account.

How to find the current rates banks are offering

Savings rates change weekly, so the rate a bank offered last month may not be the rate it offers today. To find current rates, visit the bank's website directly—the rate shown there is usually current or updated daily. Comparison sites like Bankrate, DepositAccounts, and NerdWallet aggregate rates from multiple banks and update them frequently, making it easier to see which banks are paying the most right now.

When you compare, look at the APY, not the interest rate. Check whether the rate applies to all balances or only balances above a certain threshold (some banks pay higher rates on larger deposits). Also confirm that the bank is insured by the Federal Deposit Insurance Corporation (FDIC), which protects your money up to $250,000 per account type per bank if the bank fails.

Online banks almost always pay more than traditional banks because they have fewer physical branches and lower operating costs. If you're willing to manage your account online and by phone, you can usually earn 4% to 5.35% on a savings account. If you prefer in-person banking, you'll likely earn less, but the convenience may be worth it to you.

What happens to your interest if rates fall

If you have money in a savings account and the Federal Reserve cuts rates, your bank will eventually cut the rate it pays you too. Your balance won't shrink—the money you've already earned stays in your account—but the interest you earn going forward will be smaller. This is why some people move money to CDs when rates are high: a CD locks in the rate for a set period (three months, one year, five years), so if rates fall, you keep earning the locked-in rate.

A savings account, by contrast, has a variable rate that can change at any time. This is a trade-off: you give up the certainty of a fixed rate in exchange for the ability to withdraw your money without penalty whenever you need it.

Frequently Asked Questions

Is the interest I earn on a savings account taxed?

Yes. Interest income is taxable as ordinary income at your federal tax rate and, in most states, at your state tax rate too. Banks report interest over $10 to the IRS on a Form 1099-INT. You'll owe tax on the interest whether or not the bank sends you a form, so set aside money for taxes if you earn significant interest.

Can a savings account rate go negative?

In the United States, no. Banks cannot charge you to hold money in a savings account. In some countries, banks do charge negative rates, but that doesn't happen here. The worst that can happen is that your rate drops to 0.01% or lower, meaning you earn almost nothing.

Why do online banks pay more than big banks?

Online banks have no physical branches, so they spend less on real estate, staff, and overhead. They pass some of those savings to customers in the form of higher interest rates. They also compete aggressively for deposits because they can't rely on customers who walk into a branch out of habit.

If I move my money to a higher-rate bank, do I lose the interest I already earned?

No. Interest you've already earned stays in your account and moves with you. When you transfer to a new bank, you take your full balance—principal plus all interest earned to date—with you. You only stop earning the old rate once the money leaves the old bank.

How often is interest added to my account?

Most banks compound and credit interest daily or monthly. Daily compounding is slightly better for you because you earn interest on your interest more frequently. The bank's disclosure documents will tell you the compounding frequency; look for the term "compounding" or "crediting" in the account details.
