Savings account interest rates are the percentage of your money the bank pays you each year for letting them use it

When you put money in a savings account, the bank lends that money to other customers through mortgages, car loans, and business lines of credit. In exchange, the bank pays you a small percentage of your balance as interest. That percentage is your interest rate, and it's expressed as an annual percentage yield, or APY.

Here's the simplest version: if you have $1,000 in a savings account with a 4% APY, the bank will pay you roughly $40 in interest over one year (the math is slightly more complex because interest compounds, but that's the basic idea). The rate your bank offers depends on what the Federal Reserve is doing, what type of account you have, and how much money you keep in it.

The rate you see advertised is not locked in forever. Banks change their rates regularly—sometimes weekly—based on what's happening in the broader economy. This is why the same bank might offer 4.5% one month and 4.2% the next.

Key Takeaways

  • Savings account interest rates vary by bank and account type, and they change frequently based on Federal Reserve decisions and market conditions.
  • Online banks typically offer higher rates than brick-and-mortar banks because they have lower operating costs.
  • The rate you see advertised is the current rate, not a may provide—your bank can lower it at any time, though they must notify you first.
  • Money market accounts and certificates of deposit (CDs) often pay higher rates than regular savings accounts, but with different rules about when you can withdraw your money.
  • The difference between a 2% rate and a 5% rate on $10,000 means $300 less in your pocket over a year, so comparing rates before opening an account matters.

Why rates differ between banks

Not all banks offer the same rate. An online bank like Marcus, Ally, or Discover might offer 4.5% APY on a basic savings account, while your local credit union offers 2.8%, and a major national bank like Chase or Bank of America offers 0.01%. The difference comes down to cost and competition.

Online banks have no physical branches, no tellers, and no rent to pay. That lower overhead means they can afford to pay you more interest and still make money. Traditional banks with thousands of branches have much higher costs, so they offer lower rates. Credit unions are member-owned and often offer rates somewhere in the middle, though this varies widely by institution.

Banks also compete for your money. When interest rates are rising across the economy, banks that want to attract new customers raise their rates faster. When rates are falling, they drop theirs more slowly. Shopping around before you open an account can mean hundreds of dollars in extra interest over a few years.

How the Federal Reserve influences what your bank pays

The Federal Reserve, the central bank of the United States, sets a target range for something called the federal funds rate. This is the interest rate banks charge each other for overnight loans. When the Fed raises this rate, banks' costs go up, and they typically raise the rates they pay on savings accounts. When the Fed lowers it, banks usually lower savings rates too.

The Fed doesn't directly set your savings rate—your bank does. But the Fed's decisions create the conditions that make banks want to raise or lower what they offer. If the Fed is fighting inflation by raising rates, savings rates tend to climb. If the Fed is trying to stimulate the economy by lowering rates, savings rates tend to fall.

This is why you might hear news about the Fed and suddenly notice your bank's rate has changed. The two are connected, though not in a direct one-to-one way. A 0.25% increase from the Fed might lead your bank to raise your savings rate by 0.25%, or it might raise it by 0.10%, or it might not change it at all—that's up to the bank.

The difference between fixed and variable rates

Most savings accounts have a variable rate, meaning the bank can change it whenever it wants. Your bank must notify you before lowering the rate, usually by email or mail, but they don't need your permission. The rate can go up or down based on market conditions.

Some accounts, particularly certificates of deposit (CDs), offer a fixed rate that doesn't change for the entire term of the account. If you open a one-year CD at 5% APY, that rate stays 5% for the full year, no matter what happens in the economy. The tradeoff is that you can't withdraw the money early without paying a penalty.

For a regular savings account, the variable rate is standard. This means you benefit when rates rise, but you also lose out when they fall. If you want to lock in a rate while it's high, a CD is the tool for that—but you have to be willing to leave the money untouched for the CD's term.

How to find the current best rates

The best way to find current rates is to visit bank websites directly or use rate-comparison sites like Bankrate, DepositAccounts, or NerdWallet. These sites update rates frequently and let you filter by account type, minimum balance, and whether you want an online or in-person bank.

When you're comparing, look at the APY, not just the interest rate. APY accounts for compounding—the way interest earns interest—so it's the true picture of what you'll earn. Also check the minimum balance required to open the account and whether the bank charges monthly fees, which can eat into your interest earnings.

Don't assume your current bank has the best rate. Many people keep money in accounts paying 0.01% APY straightforward because they've always banked there. Moving to a bank offering 4.5% on the same $10,000 would earn you roughly $450 more per year. That's worth the time it takes to open a new account.

What happens to your rate when the bank changes it

Banks can lower your savings rate at any time, but they must give you advance notice—usually at least 30 days, though the exact requirement varies by state. You'll receive a notice by mail, email, or through your online banking portal. You're not locked in, and you can move your money to another bank if you don't like the new rate.

When rates are falling across the economy, expect your bank to lower your rate. When rates are rising, your bank may raise your rate, but often more slowly than the Fed is raising its rate. Banks are quicker to cut rates when the economy slows than to raise them when it speeds up.

If your bank lowers your rate and you don't like it, you have options: move your money to a bank with a higher rate, move it to a CD to lock in a rate, or move it to a money market account, which sometimes pays more than a regular savings account. There's no penalty for switching banks with a savings account—you can move your money whenever you want.

Savings accounts versus other ways to earn interest

A regular savings account is the simplest way to earn interest, but it's not always the highest-paying option. Money market accounts often pay slightly higher rates than savings accounts but require a larger minimum balance and limit how many withdrawals you can make per month. Certificates of deposit (CDs) typically pay more than savings accounts because you agree to leave your money untouched for a set period—three months, one year, five years, or longer.

High-yield savings accounts are regular savings accounts offered by online banks that straightforward pay much higher rates than traditional banks. There's no special trick—they're just savings accounts at banks with lower costs. The tradeoff is that you do all your banking online rather than visiting a branch.

If you need your money to stay accessible, a high-yield savings account is usually the best choice. If you have money you won't need for a year or more, a CD might pay more. Money market accounts are a middle ground—higher rates than savings, but with some restrictions on access.

Frequently Asked Questions

Can my bank lower my interest rate without asking me?

Yes. Banks can lower your rate on a variable-rate savings account whenever they want, but they must notify you first, usually 30 days in advance. You can then move your money to a different bank if you don't like the new rate. There's no penalty for switching banks with a savings account.

Why do online banks pay more interest than big banks?

Online banks have no physical branches, no tellers, and much lower operating costs. Because they spend less money running the business, they can afford to pay you more interest on your savings and still make a profit. Traditional banks with thousands of branches have higher costs and offer lower rates.

Is my money safe if I move it to a bank with a higher rate?

Yes, as long as the bank is FDIC-insured, which nearly all banks are. FDIC insurance protects up to $250,000 per account per bank, so your money is equally safe at an online bank offering 4.5% as it is at a traditional bank offering 0.01%. You can check a bank's FDIC status on the FDIC website.

What's the difference between APY and interest rate?

Interest rate is the percentage the bank pays you. APY is the annual percentage yield—it's the interest rate plus the effect of compounding, which is when interest earns interest. APY is always equal to or higher than the stated interest rate, and it's the number you should use when comparing accounts.

If I lock money in a CD, can I get it out early?

You can withdraw the money, but you'll pay an early withdrawal penalty, which is usually a few months' worth of interest. For example, a one-year CD might charge three months of interest if you withdraw early. Read the CD terms before opening one to understand the penalty.
