Bank savings account interest rates vary by institution and account type, and they change constantly based on what the Federal Reserve does

There is no single answer to how much interest you'll earn. The rate your bank pays depends on three things: the bank itself, the type of savings account you choose, and the current economic environment. Right now, rates range from nearly 0% at some traditional banks to 4% to 5.35% at online banks and credit unions, but those numbers shift every few weeks as the Federal Reserve adjusts its benchmark rate.

The rate you see advertised is called the Annual Percentage Yield (APY). That's the actual return you'll get in a year if you don't touch the money. It's different from the interest rate itself because APY accounts for how often the bank compounds your interest — meaning they add earned interest back into your account so you earn interest on that interest too.

Your bank will tell you the APY before you open the account. You can compare rates across banks on their websites or on financial comparison sites. The difference between a 0.01% APY and a 4.5% APY is real money: on $10,000, that's the difference between $1 a year and $450 a year.

Key Takeaways

  • APY is the rate you'll actually earn in a year, and it varies widely — from under 0.1% at traditional banks to over 5% at online banks and credit unions.
  • The Federal Reserve's interest rate decisions drive what banks pay, so rates change every few weeks or months depending on economic conditions.
  • Online banks typically pay more than brick-and-mortar banks because they have lower overhead costs.
  • Money market accounts and certificates of deposit (CDs) often pay higher rates than regular savings accounts at the same bank.
  • The rate is locked in when you open the account, but banks can lower it at any time with notice — they don't have to ask permission.

Why rates differ so much between banks

Traditional banks with physical branches — the ones you can walk into — typically pay 0.01% to 0.5% APY on savings accounts. Online-only banks pay 4% to 5.35% because they don't have the cost of maintaining buildings, tellers, and branch staff. That savings gets passed to you as higher interest.

Credit unions often fall between the two. They're member-owned rather than shareholder-owned, so they can return earnings to members through better rates. Some credit unions pay 3% to 4.5% on savings accounts, though a few offer promotional rates that are even higher for limited periods.

The bank's business model also matters. Some banks use savings deposits to fund mortgages and loans. If those loans are profitable, the bank can afford to pay you more. Others rely more on fees or investment income, so they pay less on deposits.

How the Federal Reserve controls what you earn

The Federal Reserve sets a target range for the federal funds rate — the rate banks charge each other to borrow overnight. When the Fed raises this rate, banks eventually raise what they pay on savings accounts. When the Fed lowers it, banks lower savings rates too, usually within weeks.

The Fed raised rates aggressively from 2022 through 2023, which is why savings account rates climbed from near-zero to 4% and above. If the Fed cuts rates in the future, expect savings rates to fall. Banks move quickly on rate cuts because they want to keep your money, but they move slowly on rate increases because they want to attract deposits.

You can track the Fed's decisions and statements on the Federal Reserve's website. The Fed meets eight times a year to decide on rates, and those meetings are announced in advance.

The difference between savings accounts, money market accounts, and CDs

A regular savings account lets you withdraw money anytime without penalty. The APY is usually the lowest option at any given bank — currently 4% to 5% at online banks.

A money market account is a hybrid. It works like a savings account but often pays slightly higher interest — sometimes 0.25% to 0.5% more than a regular savings account at the same bank. The catch: you may have limits on how many withdrawals you can make per month, and you might need a higher minimum balance to open one.

A Certificate of Deposit (CD) is a commitment. You give the bank a sum of money for a fixed period — 3 months, 6 months, 1 year, 5 years — and the bank pays you a set APY for that entire period. CDs currently pay 4.5% to 5.5% APY depending on the term. The tradeoff: if you withdraw the money before the term ends, you pay a penalty (usually a few months of interest). CDs are useful if you know you won't need the money for a specific time period.

How interest compounds and when you see it in your account

Interest compounds on a schedule set by the bank — usually daily, monthly, or quarterly. Daily compounding is best because you earn interest on your interest more often. The difference is small on small balances but adds up on larger ones.

You'll see the interest posted to your account on the bank's schedule. Some banks add it monthly, others quarterly. You can always check your account online to see the running total. The bank will also send you a 1099-INT form at the end of the year if you earned $10 or more in interest, which you'll need for taxes.

Interest is taxed as ordinary income at your federal tax rate, and some states tax it too. If you earned $500 in interest and you're in the 24% federal tax bracket, you'll owe about $120 in federal taxes on that interest.

What happens when rates change

When you open a savings account, the APY is not locked in. Banks can lower your rate at any time with notice — usually 30 days. They don't need your permission. You'll get a notice in the mail or email, and the new rate takes effect on the date they specify.

If your bank lowers your rate and you don't like it, you can move your money to another bank. There's no penalty for closing a savings account. Many people move their money when rates drop significantly, which is why banks sometimes raise rates to keep customers.

Rate increases are rare on existing accounts. When the Fed raises rates, banks raise rates on new accounts first. If you want the higher rate, you may have to close your old account and open a new one, though some banks will match a competitor's rate if you ask.

How to find the best rate for your situation

Start by listing what you need: Do you want to access the money anytime, or can you lock it away for a set period? Do you have a large balance or a small one? Some banks have minimum balance requirements or charge monthly fees if you fall below a threshold.

Then compare APYs across banks. Online banks almost always pay more than traditional banks. Credit unions are worth checking if you're a member or can join one. Look at the bank's reputation for customer service — read recent reviews on independent sites, not the bank's own website.

Open an account at the bank with the best rate for your needs. You can do this entirely online at most institutions. Transfer your money from your old bank. The transfer usually takes 3 to 5 business days. Once the money is in, you start earning the advertised APY when ready.

Frequently Asked Questions

Can a bank change my interest rate without asking me?

Yes. Banks can lower your rate at any time with written notice, usually 30 days. They don't need your permission. If you disagree with a rate cut, you can close the account and move your money to another bank with no penalty.

Is the interest I earn on a savings account taxed?

Yes, as ordinary income at your federal tax rate. Some states tax it too. If you earn $10 or more in a year, the bank will send you a 1099-INT form for your tax return. Interest earned in a Roth IRA or traditional IRA is not taxed the same way.

Why do online banks pay more interest than regular banks?

Online banks have no physical branches, so they spend far less on buildings, staff, and equipment. They pass those savings to customers through higher interest rates on deposits. The trade-off is you can't walk into a branch — everything is done online or by phone.

What's the difference between APY and interest rate?

The interest rate is the percentage the bank pays. APY is the actual return you get in a year after accounting for how often interest compounds. APY is always equal to or higher than the stated rate, so it's the number to compare between banks.

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

No. Interest you've already earned stays in your account. When you transfer the money, you move the full balance including all interest earned to date. You only stop earning interest at the old bank once the money leaves.
