A good APY depends on what banks are currently offering, not on a fixed number

There is no universal "good" APY — it moves with the Federal Reserve's interest rate decisions and changes month to month. What matters is comparing what you can actually get today against what other banks are offering today. A rate that was competitive six months ago may be below average now.

The fastest way to know if a rate is good is to check what high-yield savings accounts are paying right now, since they set the market standard. If a bank is offering significantly less than the highest rates available, it is not competitive. If it matches or beats the top tier, it is good. The difference between a good rate and a mediocre one can add hundreds of dollars per year on a $10,000 balance.

Key Takeaways

  • High-yield savings accounts typically offer the highest APY available to regular depositors, and comparing against them tells you whether any other rate is competitive.
  • The difference between a 4.5% APY and a 0.01% APY on $10,000 is roughly $450 per year, so rate shopping matters even for modest balances.
  • Online banks and credit unions often post higher rates than brick-and-mortar banks because they have lower overhead costs.
  • APY compounds daily or monthly depending on the bank, so two accounts with the same stated rate may earn slightly different amounts.
  • Your rate can change at any time after you open the account, so checking rates quarterly helps you know when to move money if a better option appears.

How to tell if a rate is competitive right now

Open a rate-comparison tool or visit the websites of three to five online banks and note what they are currently offering on savings accounts. The highest rates you see are the benchmark. If a bank is offering within 0.25% of that top rate, it is competitive. If it is 0.5% or more below, you are leaving money on the table.

The top-paying accounts change frequently because banks adjust rates to attract or shed deposits. A bank that was leading last month may drop its rate this month. This is normal and expected. Checking rates every three months takes five minutes and can reveal whether your current account is still worth keeping.

Why online banks and credit unions often pay more

Online banks have no physical branches, so they spend less on rent, staff, and overhead. They pass some of that savings to depositors through higher rates. Credit unions are member-owned cooperatives and often prioritize member returns over shareholder profit, which can also mean higher rates on savings.

Brick-and-mortar banks typically pay lower rates because they fund themselves partly through lending and partly through deposit fees and service charges. They do not need to compete aggressively on savings rates. If you bank with a traditional bank for convenience, you are usually paying for that convenience in lower interest earnings.

The difference between daily and monthly compounding

APY already accounts for compounding, so the stated rate is what you will earn regardless of compounding frequency. However, the frequency matters for how often interest is added to your balance. With daily compounding, interest is calculated and added every day, so your balance grows slightly faster. With monthly compounding, it happens once a month.

On a $10,000 balance at 4.5% APY, the difference between daily and monthly compounding is roughly $1 to $2 per year — small enough that it should not be your deciding factor. But if two banks offer the same rate and one compounds daily, that one is marginally better.

What happens when the Federal Reserve changes rates

When the Federal Reserve raises or lowers its benchmark rate, banks adjust their savings rates within days or weeks. During periods when the Fed is raising rates, savings APYs climb. During periods when the Fed is cutting rates, savings APYs fall. This is why a rate that felt generous last year may feel ordinary now.

Your bank can change your rate at any time after you open the account. They must notify you before the change takes effect, but you have no contractual right to keep the old rate. If your bank cuts its rate and you find a better option elsewhere, you can move your money. There is no penalty for switching savings accounts.

How much difference does rate shopping actually make

On smaller balances, the dollar difference is modest. On a $5,000 balance, the difference between 4.5% and 0.5% is about $20 per year. On a $50,000 balance, it is roughly $200 per year. On a $100,000 balance, it is about $400 per year. These are not life-changing sums, but they are real money for doing nothing except opening an account at a different bank.

The real value of rate shopping is the habit itself. If you check rates twice a year and move money when a significantly better option appears, you will earn more over time than someone who never looks. You also stay aware of what the market is doing, which helps you make better decisions about whether to keep money in savings or move it elsewhere.

Factors beyond APY that affect your choice

A slightly lower rate at a bank with no monthly fees may beat a slightly higher rate at a bank that charges $10 per month for falling below a minimum balance. Read the fee schedule before you open an account. Look for banks with no monthly maintenance fees, no minimum balance requirements, and no limits on how many times you can withdraw per month.

FDIC insurance protects deposits up to $250,000 per account holder per bank. If you have more than $250,000 to save, you can open accounts at multiple banks to keep all your money insured. Credit unions are insured by the NCUA up to the same limit. Verify that any bank you choose carries insurance before you deposit money.

Frequently Asked Questions

Is 4% APY on a savings account good?

It depends on the current market. When the Federal Reserve's rates are high, 4% may be below average. When rates are low, 4% may be excellent. Check what online banks are offering this week — if 4% is within 0.25% of the highest rate you see, it is competitive. If it is 0.5% or more below, look for a better option.

Do I lose money if I move my savings to a different bank?

No. Moving money between banks costs nothing and takes a few days. Your old bank will not charge you for closing the account. The new bank may offer a sign-up bonus for opening an account with a certain deposit, which can add to your earnings. There is no penalty for switching.

Can a bank lower my APY without warning?

A bank must notify you before lowering your rate, but they can do it at any time after you open the account. You have no contractual right to keep the original rate. If your bank cuts its rate and you find a better option, you can move your money to a higher-paying account.

What is the difference between APY and interest rate?

APY includes the effect of compounding, so it is always equal to or higher than the stated interest rate. The APY is what you will actually earn. If a bank states "4.5% APY", that is the number to use when comparing against other banks.

Should I move my money if rates drop by 0.1%?

Probably not. The time and effort to move money is not worth $10 per year on a $10,000 balance. Move when the gap is 0.5% or larger, or when you are opening a new account anyway. Checking rates quarterly helps you spot larger drops before they cost you significantly.
