Yes, savings accounts earn interest, but the amount depends on the bank and the rate they offer

A savings account is a deposit account where the bank pays you interest on the money you keep there. The bank uses your deposits to lend to other customers, and in return, it shares a portion of what it earns with you as interest. The interest rate—expressed as an annual percentage rate, or APY—tells you how much you'll earn in a year if you leave the money untouched.

The catch is that interest rates vary widely. A traditional bank might offer 0.01% APY, meaning $10,000 would earn about $1 per year. An online bank might offer 4.5% or higher, meaning the same $10,000 would earn around $450 per year. The difference between these two scenarios is real money, and it compounds over time.

Interest is calculated daily or monthly, depending on the bank's terms, but it's usually credited to your account monthly. You don't have to do anything to earn it—the bank deposits it automatically as long as your account remains open and funded.

Key Takeaways

  • Every savings account earns interest, but the rate varies from under 0.01% at traditional banks to over 4% at online banks.
  • APY is the annual percentage yield—the percentage of your balance you'll earn in interest over one year.
  • Interest compounds, meaning you earn interest on your interest, so higher rates matter more the longer money sits in the account.
  • Online banks typically offer higher rates than brick-and-mortar banks because they have lower overhead costs.
  • The Federal Reserve sets a benchmark rate that influences what banks offer, so rates change over time.

How APY and interest rates are set

Banks set their own interest rates based on what the Federal Reserve does with its benchmark rate. When the Fed raises rates, banks have more incentive to offer higher APY to attract deposits. When the Fed lowers rates, banks lower what they pay you. This is why savings account rates change throughout the year—sometimes dramatically.

Online banks tend to offer higher rates than traditional banks because they don't maintain physical branches, which cuts their costs. They pass some of those savings to customers in the form of better interest rates. Traditional banks, by contrast, have overhead from staffing branches and ATM networks, so they offer lower rates.

Some banks also offer promotional rates—a higher APY for a limited time to attract new customers. These rates often drop after the promotional period ends, so read the fine print before opening an account based on a headline rate.

How interest compounds and grows your balance

Interest compounds when the bank adds earned interest to your account balance, and then you earn interest on that new, larger balance. The more often interest compounds—daily, weekly, or monthly—the more you earn overall, though the difference is usually small.

Here's a concrete example: if you deposit $5,000 in an account earning 4% APY compounded daily, after one year you'll have about $5,204. After five years, you'll have about $6,083. After ten years, about $7,401. The longer the money stays in the account, the more the compounding effect adds up. At 0.01% APY, the same $5,000 grows to only $5,000.50 after one year—a difference of over $200 per decade.

This is why the rate matters. Even a 1% difference in APY can mean hundreds of dollars over several years on a modest balance.

Where to find current interest rates

Interest rates change frequently, so the rate you see today may not be the rate you get tomorrow. Most banks publish their current rates on their websites, usually on the savings account product page or in a rates table.

Comparison sites like Bankrate, DepositAccounts, and NerdWallet update rates daily and let you filter by account type, bank type (online vs. traditional), and minimum deposit. These sites don't charge you to use them—they make money when you click through to open an account.

If you already have a savings account, log into your online banking portal to see your current rate. Banks are required to disclose the APY in writing when you open the account, and they must notify you before changing the rate.

Minimum deposits and balance requirements

Most online banks have no minimum deposit requirement to open a savings account, though some traditional banks require $100 to $500 to start. A few banks offer higher rates if you maintain a larger balance—for example, 4.5% APY on balances of $25,000 or more, and 3.5% on smaller balances.

Read the account terms carefully. Some banks charge a monthly fee if your balance falls below a certain amount, which can wipe out the interest you earn. Others waive fees for customers who set up direct deposit or maintain a linked checking account.

FDIC insurance and safety

The FDIC (Federal Deposit Insurance Corporation) protects your deposits up to $250,000 per account holder, per bank. This means if the bank fails, the government guarantees you'll get your money back up to that limit. This protection applies to all savings accounts at FDIC-insured banks, whether they're online or traditional, and whether the rate is high or low.

Check whether a bank is FDIC-insured before you open an account. You can search the FDIC's bank database on their website. Credit unions offer similar protection through the NCUA (National Credit Union Administration) up to the same $250,000 limit.

When to move your money to a higher-rate account

If your current bank offers a much lower rate than what's available elsewhere, moving your money to a higher-rate account makes financial sense. The process is straightforward: open a new account at the higher-rate bank, then transfer your balance from the old account. Most banks can initiate an ACH transfer, which takes three to five business days.

The only cost is your time. There's no fee to transfer money between banks, and you won't lose FDIC protection during the move. Some banks offer cash bonuses when you open a new account and deposit a certain amount, which can add to your earnings in the first year.

If you're earning 0.01% at a traditional bank and can move to 4% at an online bank, the difference on a $10,000 balance is about $400 per year. Over five years, that's $2,000 in extra interest—money that costs you nothing but a few minutes to claim.

Frequently Asked Questions

Do I have to pay taxes on savings account interest?

Yes. Interest earned in a savings account is taxable income. Banks send you a 1099-INT form at the end of the year if you earned $10 or more in interest, and you report it on your tax return. The amount of tax you owe depends on your overall income and tax bracket.

Can a bank lower my interest rate without warning?

Banks can lower rates, but they must notify you in advance—usually 30 days. You'll receive notice by mail, email, or through your online banking portal. If you disagree with the new rate, you can close the account and move your money elsewhere without penalty.

What's the difference between APY and APR?

APY (annual percentage yield) includes the effect of compounding, so it's the true rate you earn on savings. APR (annual percentage rate) does not include compounding and is used mainly for loans and credit cards. For savings accounts, always look at the APY.

Is a high-yield savings account the same as a regular savings account?

A high-yield savings account is a regular savings account that simply offers a higher interest rate, usually at an online bank. It has the same FDIC protection and the same basic features—you can deposit and withdraw money whenever you want. The only difference is the rate.

What happens to my interest if I withdraw money before the end of the year?

You earn interest on the money for the time it sits in the account. If you deposit $5,000 and withdraw it after six months, you earn interest for those six months only. Interest accrues daily, so you don't lose anything by withdrawing early.
