Most savings accounts do earn interest, but the rate varies widely by bank and account type
Yes, savings accounts earn interest. The bank pays you a percentage of the money you keep in the account, calculated daily or monthly and added to your balance. The rate you receive depends on the bank, the type of account, and the current interest rate environment set by the Federal Reserve.
Right now, rates range from nearly zero at some large national banks to around 4% to 5% at online banks and credit unions. A decade ago, rates were much higher; in 2008, they were much lower. The rate your bank offers you today may be different next month.
Interest is not a refund or a payment you receive separately. It is money the bank adds directly to your account balance. If you have $10,000 in an account earning 4.5% annually, the bank adds roughly $450 to your balance over the course of a year, though the actual amount depends on how the bank calculates it.
Key Takeaways
- Savings account interest rates vary from under 0.01% at major national banks to 4% to 5% at online banks and credit unions.
- The Federal Reserve's interest rate decisions affect what banks offer, so rates change over time and differ between institutions.
- Interest is calculated on your daily or monthly balance and added directly to your account, not sent to you separately.
- High-yield savings accounts and money market accounts typically pay more interest than standard savings accounts at the same bank.
- The amount of interest you earn depends on your balance, the rate offered, and how long your money stays in the account.
Why interest rates differ so much between banks
Large national banks like Bank of America, Chase, and Wells Fargo typically offer savings rates between 0.01% and 0.05%. Online banks like Marcus, Ally, and American Express Personal Savings offer rates between 4% and 5%. Credit unions often fall somewhere in between, usually between 0.5% and 3%.
The difference comes down to cost. Online banks have lower overhead—no physical branches, fewer employees—so they can afford to pass more of their earnings to depositors. National banks have thousands of branches and staff, which costs money. They make their profit differently: by lending out deposits at higher rates and keeping the difference.
Credit unions are member-owned nonprofits, so they return earnings to members through better rates and lower fees. However, not all credit unions offer high rates; some are small and conservative with their lending, so they offer lower rates to depositors.
How to compare rates across different account types
The most common types of interest-bearing savings accounts are standard savings accounts, high-yield savings accounts, and money market accounts. Standard savings accounts at national banks earn the least. High-yield savings accounts, usually at online banks or credit unions, earn the most. Money market accounts sit in the middle and often require a higher minimum balance.
To compare, visit each bank's website and look for the stated Annual Percentage Yield, or APY. This is the rate you will actually earn over a year, accounting for how often the bank compounds interest. Do not compare the interest rate alone; always compare the APY.
Keep in mind that rates change. A bank offering 4.5% today might drop to 4% next month. Some banks lower rates gradually; others drop them suddenly. If rate changes matter to you, read the bank's terms to see whether they notify you before a change and how often they adjust.
What affects how much interest you actually earn
Three things determine your interest earnings: the APY, your account balance, and the time your money stays in the account. A $10,000 balance at 4.5% APY earns roughly $450 per year. A $1,000 balance at the same rate earns roughly $45 per year. Double the balance, and you double the interest.
The timing also matters. If you deposit $10,000 on January 1 and leave it there all year, you earn the full year's interest. If you deposit it on July 1, you earn roughly half. If you withdraw money mid-month, the bank typically calculates interest on your daily balance, so you earn less for the days the money was not there.
Some accounts have minimum balance requirements. If your balance drops below the minimum, the bank may charge a fee, lower your rate, or close the account. Read the account terms to understand what happens if your balance fluctuates.
How interest is calculated and added to your account
Banks calculate interest one of two ways: daily or monthly. With daily calculation, the bank figures out what you earned each day based on that day's balance, then adds it all up at the end of the month. With monthly calculation, the bank uses your average balance for the month.
Daily calculation almost always pays more, because interest compounds—you earn interest on your interest. If your bank adds $10 in interest one month, the next month you earn interest on the original balance plus that $10.
Interest is added directly to your account balance. You do not receive a check or a separate payment. You can withdraw the interest along with your principal at any time, or leave it in the account to earn more interest.
When interest rates rise and fall, and what that means for you
The Federal Reserve sets a target interest rate that influences what banks offer. When the Fed raises its rate, banks usually raise savings rates within weeks or months. When the Fed lowers its rate, banks usually lower savings rates more slowly—sometimes taking months to pass the cut to depositors.
If you are earning 4.5% and the Fed cuts rates, your bank may drop your rate to 3.5% or lower. You have no control over this, but you can move your money to a bank offering a better rate. There is no penalty for moving money between savings accounts at different banks.
If rates are falling, locking in a high rate now by moving to a high-yield account makes sense. If rates are rising, you might wait to see where they settle before moving. Check rate comparison sites like Bankrate or DepositAccounts to see current rates across banks.
Frequently Asked Questions
Do I have to pay taxes on savings account interest?
Yes. Interest is taxable income. Banks send you a 1099-INT form at the end of the year if you earned $10 or more in interest. You report this on your tax return. The amount of tax you owe depends on your tax bracket and total income.
Can a bank lower my interest rate without warning?
Yes. Banks can change rates at any time unless your account terms may provide a fixed rate for a specific period. Most savings accounts do not have fixed rates. Read your account agreement to see what notice, if any, the bank promises to give before a rate change.
What is the difference between APR and APY?
APR is the annual percentage rate; APY is the annual percentage yield. APY accounts for compounding, so it is always equal to or higher than APR. Always compare APY when looking at savings accounts, because it shows what you will actually earn.
Is my interest-earning money safe if the bank fails?
Yes, up to $250,000 per account holder per bank. The Federal Deposit Insurance Corporation, or FDIC, insures deposits at most banks. Credit union deposits are insured by the National Credit Union Administration, or NCUA, also up to $250,000. Check your bank's website to confirm it carries this insurance.
Should I move my money to a higher-rate bank?
If your current bank pays under 1% and online banks are paying 4% or higher, moving makes financial sense. The process takes a few days. However, if you have automatic bill payments or direct deposit set up, you will need to update those accounts at your new bank before closing the old one.
