Your rate depends on the account type, the bank, and how much you deposit

The interest rate you receive is not set by any central authority — each bank or credit union decides its own rates, and those rates change weekly or even daily. A savings account at one bank might pay 4.50% while another pays 2.00% for the exact same account type. The difference between these two rates means hundreds of dollars per year on a $10,000 balance, so shopping around is not optional.

Your rate also depends on what you are saving in. A high-yield savings account will pay more than a regular savings account at the same institution. A certificate of deposit (CD) will pay more than a savings account, but you cannot touch the money without a penalty. Money market accounts, Treasury bills, and bonds all have different rate structures. The longer you lock your money away, the higher the rate usually is — but not always, and the relationship changes based on what the Federal Reserve is doing.

Banks use your rate to compete for deposits. When the Federal Reserve raises its benchmark rate, banks raise their savings rates to attract customers. When the Fed cuts rates, banks cut theirs. But they do not move in lockstep, and some banks lag weeks behind others. Online banks typically offer higher rates than brick-and-mortar banks because they have lower overhead costs.

Key Takeaways

  • Each bank sets its own rate independently, so comparing rates across institutions can mean the difference of hundreds of dollars per year on the same deposit amount.
  • High-yield savings accounts, CDs, and money market accounts all pay different rates at the same bank, with longer-term CDs usually paying more than shorter terms.
  • Online banks typically offer higher rates than traditional banks because they spend less on physical branches and staff.
  • Rates change based on Federal Reserve policy, but banks do not all raise or lower their rates on the same day, so timing your deposit can matter.
  • The rate you see advertised is the annual percentage yield (APY), which includes the effect of compounding and is the number to use when comparing accounts.

How banks decide what rate to offer you

Banks offer higher rates on accounts where they expect the money to stay longer. A CD that locks your money for 12 months will pay more than a savings account where you can withdraw anytime. A 5-year CD will pay more than a 1-year CD. This is because the bank can lend out your money for longer and earn more interest on it, so they share some of that gain with you.

Banks also raise rates when they need deposits. If a bank is growing fast and needs cash to lend out, it will raise its savings rates to pull in more customers. If a bank already has plenty of deposits, it can afford to pay less. This is why you will sometimes see a small bank offering a rate much higher than the national average — they are hungry for deposits.

Your own balance size rarely affects the rate you get, unless you are depositing a very large amount ($100,000 or more) into a jumbo account. Most banks offer the same rate to everyone on a given account type, regardless of whether you have $500 or $50,000 in the account.

The difference between APY and interest rate

Banks advertise a rate called the annual percentage yield (APY), not the raw interest rate. The APY includes the effect of compounding — the way interest gets added to your balance and then earns interest itself. If a bank compounds interest daily, your APY will be slightly higher than the stated interest rate. If it compounds monthly, the difference is smaller.

When you compare two accounts, always use the APY, not the interest rate. The APY is the true number that tells you how much money you will have at the end of a year. A savings account advertising 4.50% APY will earn you more than one advertising 4.45% APY, even if the difference seems small. On $10,000, that 0.05% difference is $5 per year — small, but real.

Where to find current rates

You can see what rates banks are currently offering by visiting their websites directly. Most banks display their savings rates and CD rates on the homepage or in a rates section. Online banks like Marcus, Ally, and American Express Personal Savings post their rates publicly because they compete on rate alone.

Comparison sites like Bankrate, DepositAccounts, and FDIC's BankFind tool let you filter by account type and see rates from multiple banks at once. These sites update rates regularly, though not always in real time. Call the bank directly if you see a rate you want to lock in, because rates can change between when a website updates and when you open the account.

Credit unions often offer competitive rates on savings accounts and CDs. You can search for credit unions in your area through the CO-OP Network or Alliant Credit Union's locator tool. Credit unions are member-owned, so they sometimes pay higher rates than banks because they do not have to generate profit for shareholders.

How Federal Reserve decisions affect your rate

The Federal Reserve sets a benchmark interest rate that influences all other rates in the economy. When the Fed raises its benchmark rate, banks have more incentive to raise savings rates because they can earn more by lending money out. When the Fed cuts rates, banks cut savings rates because lending is less profitable.

However, banks do not move instantly. Some banks raise rates within days of a Fed decision. Others wait weeks or months. Online banks tend to move faster than traditional banks. If the Fed just cut rates and you are shopping for a CD, you might find that some banks have already lowered their CD rates while others have not — this is your window to lock in a higher rate before it drops everywhere.

The relationship between Fed policy and savings rates is not one-to-one. If the Fed raises its benchmark rate by 0.25%, banks might raise savings rates by 0.10% or 0.30% depending on how much they need deposits. There is no rule that forces them to pass along the full increase.

Rate locks and promotional rates

Some banks offer a promotional rate that is higher than their standard rate, but only for a limited time or only on new deposits. A bank might offer 5.00% APY on a 12-month CD for the first 30 days, then drop it to 4.50%. If you open the account during the promotional period, you lock in 5.00% for the full 12 months. If you open it after, you get 4.50%.

Once you open a CD, your rate is locked in for the term. If you open a 12-month CD at 4.75%, you will earn 4.75% for the full 12 months even if rates drop to 3.00% next month. This is a protection: you cannot lose your rate. But it also means you are stuck if rates rise and you want to move your money.

Savings accounts and money market accounts do not lock in a rate. The bank can lower your rate anytime, though they usually give you notice. If you are in a high-yield savings account earning 4.50% and the bank drops it to 3.75%, you can move your money to another bank without penalty.

Why the same account type pays different rates at different banks

Two banks offering the same product — say, a 12-month CD — will often have different rates because they have different business strategies. An online bank with no branches can afford to pay more because it spends less on overhead. A large national bank might pay less because it has brand recognition and does not need to compete on rate. A small regional bank might pay more because it is trying to grow.

The health of the bank also matters. A bank that is struggling financially might raise rates aggressively to pull in deposits. A bank that is profitable and stable might not need to. You can check a bank's safety rating through the FDIC's BankFind tool or through Bankrate's safety ratings, which are based on regulatory data.

Market conditions matter too. When the economy is strong and people are confident, banks do not need to pay as much to attract deposits. When there is uncertainty, banks raise rates to make savings accounts more attractive. This is why you sometimes see a sudden jump in rates across the industry — the market has shifted, and banks are competing harder for your money.

Frequently Asked Questions

Can I negotiate my interest rate with a bank?

No. Banks set rates publicly and offer the same rate to all customers on a given account type. You cannot call and ask for a higher rate. Your only option is to move your money to a bank offering a better rate.

Will my rate go down if I leave money in a savings account for a long time?

Yes, possibly. Savings accounts and money market accounts have variable rates that banks can change anytime. CDs have fixed rates that cannot change during the term. If you want to lock in a rate, use a CD. If you want flexibility, accept that your rate may drop.

What is the highest interest rate I can get right now?

Rates change daily, so there is no single answer. Check Bankrate, DepositAccounts, or your local credit union's website to see current rates. Online banks typically offer the highest rates on savings accounts and CDs, but compare APY across at least three institutions before deciding.

Does opening multiple accounts at the same bank get me a higher rate?

No. Banks offer the same rate to all customers on a given account type, regardless of how many accounts you have with them. The rate is based on the account type and current market conditions, not on your loyalty or account balance.

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

No. Interest you have already earned stays in your account. You only lose interest if you withdraw from a CD before it matures — the bank charges an early withdrawal penalty, which is usually a few months of interest. Moving money between banks does not trigger a penalty.
