Savings account interest rates are the percentage your bank pays you each year for keeping money in the account

When you deposit money into a savings account, the bank uses that money to lend to other customers. In exchange, the bank pays you a small percentage of your balance as interest. That percentage is the interest rate. If your account earns 4.5% annual percentage yield (APY), a $1,000 balance would earn roughly $45 in interest over a year—though the actual amount depends on how often the bank compounds the interest and how your balance changes.

The rate you see advertised is not fixed forever. Banks change their rates regularly, sometimes weekly. The rate you get when you open an account may be different three months later. Some accounts lock in a rate for a set period; most savings accounts do not. Understanding what moves these rates and where to find the current ones matters more than chasing a single number.

Key Takeaways

  • Savings account interest rates are set by individual banks and change frequently—there is no single "the" rate that applies everywhere.
  • The Federal Reserve's interest rate decisions influence what banks offer, but banks choose their own rates based on competition and their own costs.
  • Online banks typically offer higher rates than brick-and-mortar banks because they have lower operating costs.
  • The rate you receive when you open an account may drop after a promotional period ends or when the Federal Reserve cuts rates.
  • APY (annual percentage yield) includes the effect of compounding, so it is more accurate than a straightforward interest rate for comparing accounts.

How banks decide what rate to offer

Banks do not set savings rates in a vacuum. The Federal Reserve sets a target range for the federal funds rate—the rate banks charge each other for overnight loans. When the Fed raises or lowers this rate, banks adjust what they pay depositors and charge borrowers. If the Fed raises rates, banks have more incentive to attract deposits and may raise savings rates. If the Fed cuts rates, banks often lower what they pay you.

Beyond the Fed's influence, each bank competes for deposits based on its own situation. A bank with plenty of deposits may lower its savings rate because it does not need to attract more money. A bank trying to grow may offer a higher rate to pull in new customers. Online banks—which have no physical branches and lower staff costs—often offer higher rates than traditional banks because they can afford to pay more and still be profitable.

Banks also consider what they can earn by lending out your deposits. If loan demand is weak, banks earn less on the money you deposit, so they pay you less. If loan demand is strong, banks can afford to pay higher rates and still make a profit.

The difference between the advertised rate and what you actually earn

The rate a bank advertises is usually the APY—annual percentage yield. This number includes the effect of compounding, which means interest earned 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. The APY reflects this; a straightforward interest rate would not.

Some banks offer promotional rates for new customers. You might see 5.0% APY advertised, but that rate may only explore for the first three months. After that, the rate drops to 0.5% or lower. Read the terms carefully. The promotional period and the regular rate should both be stated clearly.

Your actual earnings also depend on your balance and how long money stays in the account. If you deposit $10,000 and withdraw it after six months, you earn interest only on that six-month period, not the full year. Banks calculate interest daily or monthly depending on their terms, so the exact amount varies.

Why rates change and what triggers a drop

Savings rates move most often when the Federal Reserve changes its policy. The Fed meets eight times a year and can raise, lower, or hold steady its target rate. When the Fed raises rates, banks usually raise savings rates within weeks. When the Fed cuts rates, banks often cut savings rates faster than they raised them—sometimes within days.

Rates also drop when a promotional period ends. If you opened an account at 5.0% APY and the fine print said that rate lasted three months, expect it to fall to the bank's standard rate after 90 days. This is not a surprise or a mistake; it is how the promotion works.

Individual banks may also lower rates if they have enough deposits and no longer need to attract new customers. You might see one bank lower its rate while competitors keep theirs steady. This is why shopping around matters—the best rate today may not be the best rate next month, but some banks will always be higher than others.

Where to find current rates and how to compare them

No single website shows every bank's rate, but several sites aggregate them. Bankrate, DepositAccounts, and the Federal Deposit Insurance Corporation (FDIC) website all list current rates at major banks. These sites update frequently, though not always in real time. The most accurate source is always the bank's own website, where you can see the exact APY and any terms attached to it.

When comparing rates, look at the APY, not just the interest rate. Check whether the rate is promotional or permanent. Read the minimum balance requirement—some banks offer high rates only on balances above $25,000 or $100,000. Look at how often interest compounds and whether the bank charges monthly fees that would eat into your earnings.

A 4.5% APY at one bank with no fees and daily compounding is better than 4.6% at another bank with a $10 monthly fee and monthly compounding. Do the math on a balance you actually plan to keep in the account.

What happens to your rate if you already have an account

If you opened a savings account months or years ago, your rate is probably lower than what new customers see today. Banks often offer higher rates to new depositors while paying existing customers less. This is called tiering, and it is legal. Your bank is not required to match the rate it offers new customers.

You have two options: stay put and accept the lower rate, or move your money to a bank offering a better rate. Moving is free—you can open a new account at another bank and transfer your balance without penalty. Some people keep multiple savings accounts at different banks to take advantage of promotional rates, then move money when the promotion ends.

If you call your bank and ask them to match a competitor's rate, they may or may not do it. Large banks rarely negotiate on savings rates. Smaller banks and credit unions are more likely to match a competitor's offer if you ask. It costs nothing to ask, but do not expect a yes.

How inflation affects what your savings rate is really worth

A 4.5% savings rate sounds good until you consider inflation. If inflation is running at 3.5% per year, your real earnings—what you can actually buy with the interest—is only about 1%. If inflation rises to 5% and your rate stays at 4.5%, you are losing purchasing power even though the account is earning interest.

This is why the relationship between the Federal Reserve's rate and inflation matters. When inflation rises, the Fed typically raises rates to cool it down. Banks then raise savings rates. When inflation falls, the Fed cuts rates and banks cut savings rates. The goal is to keep real returns (earnings minus inflation) roughly stable, though this does not always work perfectly.

You cannot control inflation, but you can control where you keep your money. If savings rates are low and inflation is high, a high-yield savings account at an online bank is still your best option for cash you need to access quickly. For money you will not touch for years, other options like certificates of deposit (CDs) or bonds may offer better protection against inflation.

Frequently Asked Questions

Can a bank lower my interest rate without warning?

Yes. Banks can change savings rates at any time unless you have a promotional agreement that specifies a locked rate for a set period. Most savings accounts have no rate lock. Your bank should notify you before a rate change, but the change itself is legal. Check your account terms to see if any promotional rate has an end date.

Why do online banks pay more interest than big banks?

Online banks have lower overhead costs—no physical branches, fewer employees, lower rent. They pass some of those savings to customers by offering higher rates. They still make a profit by lending out deposits at higher rates than they pay you. Big banks have more expenses, so they can afford to pay less and still be profitable.

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

Yes, as long as the bank is insured by the Federal Deposit Insurance Corporation (FDIC) or the National Credit Union Administration (NCUA). Check the bank's website or call to confirm. FDIC insurance covers up to $250,000 per account holder per bank, so your deposits are protected even if the bank fails. The interest rate has no effect on safety.

What is the difference between APY and APR on a savings account?

APY (annual percentage yield) includes compounding and shows what you actually earn. APR (annual percentage rate) is a straightforward rate without compounding. For savings accounts, always compare APY to APY. APR is used mainly for loans and credit cards, where it works differently.

Should I move my money every time a competitor offers a higher rate?

Not necessarily. Moving money takes time and effort, and rates change constantly. If a competitor's rate is 0.25% higher, the extra earnings on a $10,000 balance would be $25 per year—probably not worth the hassle. If the difference is 1% or more, moving makes sense. Also consider whether the higher rate is promotional and will drop after a few months.
