Yes, savings accounts earn interest, but the amount depends on the bank and the rate they set

A savings account earns interest when the bank pays you a percentage of the money you keep deposited. The bank uses your money to lend to other customers or invest it, and they share a portion of what they earn with you as interest. The rate changes based on what the Federal Reserve does with its benchmark rate, what the bank decides to offer, and the type of account you have.

Interest is calculated daily or monthly, depending on the bank's terms, and added to your account automatically. You do not have to do anything to earn it—the money sits there and grows. The growth is small compared to what you might earn in investments, but it is may provide and your money stays safe.

Key Takeaways

  • Banks pay interest on savings accounts as a percentage of your balance, calculated either daily or monthly.
  • The interest rate your bank offers changes when the Federal Reserve adjusts its rates, usually within weeks.
  • High-yield savings accounts currently pay more interest than traditional savings accounts at the same bank.
  • Interest earned is taxable income, and your bank will send you a 1099-INT form if you earn $10 or more in a year.

How the Federal Reserve affects what your bank pays you

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 this rate, banks have less incentive to borrow from each other, so they compete harder for customer deposits by raising the interest rates they offer on savings accounts. When the Fed lowers rates, banks lower what they pay you.

This does not happen when ready. Banks usually adjust their rates within one to three weeks of a Fed decision, though some move faster and some slower. A bank that raised rates quickly when the Fed was hiking may also lower rates quickly when the Fed starts cutting. There is no rule that forces them to match the Fed's moves exactly, so rates vary widely between banks even when the Fed's rate is the same.

The difference between traditional and high-yield savings accounts

A traditional savings account at a large bank typically pays between 0.01% and 0.05% annual interest. A high-yield savings account, usually offered by online banks or credit unions, typically pays between 4% and 5.35% annual interest. The difference comes down to overhead: online banks have lower costs than branches, so they can afford to pay more.

The money is equally safe in both. Both types are insured by the Federal Deposit Insurance Corporation (FDIC) up to $250,000 per account holder per bank. The trade-off is access: a high-yield account may have fewer ways to withdraw money, or it may be at a bank with no physical locations. A traditional account lets you walk into a branch, but you earn almost nothing on your balance.

How much interest you actually earn

Interest is calculated on your average daily balance or your ending balance, depending on the bank. Most banks use average daily balance, which means they add up what you had in the account each day of the month, divide by the number of days, and calculate interest on that number. If you deposit $10,000 on the first of the month and leave it there, you earn interest on the full $10,000. If you withdraw $5,000 on the 15th, the bank calculates interest on roughly $7,500 for the month.

The actual dollar amount is small at traditional rates. On $10,000 at 0.05% annual interest, you earn about $5 per year. On the same $10,000 at 4.5% annual interest, you earn about $450 per year. The difference matters more the longer you leave the money untouched and the larger your balance.

When interest is added to your account

Interest is either compounded daily or monthly. Compounding means the bank calculates interest on your balance plus the interest you have already earned. If you earn $1 in interest one month and the bank compounds monthly, next month's interest is calculated on your original balance plus that $1. Over time, this creates a small snowball effect, though the difference between daily and monthly compounding is usually just a few dollars per year on typical balances.

Most banks post interest monthly, on the last day of the month or the first day of the next month. Some post it quarterly. Check your account statement or the bank's website to see when yours posts. Once it is posted, it is yours—the bank cannot take it back.

Interest and taxes

Interest you earn is taxable income. Your bank reports it to the IRS on a 1099-INT form if you earn $10 or more in a calendar year. You report this income on your tax return, and you owe federal income tax on it at your regular tax rate. Some states also tax interest income, depending on where you live.

This means the real return on your savings is lower than the stated interest rate. If you earn $450 in interest and you are in the 22% federal tax bracket, you owe about $99 in federal tax, leaving you with $351. This is still worth doing—savings accounts are meant to be safe, not to beat inflation—but it is worth knowing that the number on your statement is not the number you keep.

What happens if interest rates fall

If you have money in a savings account and the Federal Reserve cuts rates, your bank will lower the interest rate it pays you. This usually happens within weeks. Your balance does not shrink—you still have the same dollars—but the amount of new interest you earn each month will be smaller going forward.

This is why some people move money to a high-yield account when rates are high: they lock in a better rate before it falls. However, you cannot lock in a rate at a savings account the way you can with a certificate of deposit (CD). A savings account rate can change at any time, and the bank only has to give you notice before it takes effect. If you want a may provide rate for a set period, a CD is the right tool.

Frequently Asked Questions

Can I lose money in a savings account?

No. Your principal—the money you deposit—is insured by the FDIC up to $250,000 per account holder per bank. Interest rates can fall, so you earn less, but you cannot lose what you put in. The only way to lose money is if you withdraw more than you have, which the bank will not let you do.

Why do some banks pay almost no interest?

Large banks with many branches have higher costs and less need to compete for deposits because customers come for the convenience of the branch network. Online banks have no branches, so they compete on rate. If you want meaningful interest, you need to move your money to a bank that is competing on rate, not convenience.

Is a savings account better than keeping cash at home?

Yes. Cash at home earns zero interest and can be lost or stolen. A savings account earns interest, even if it is small, and is insured. Even at 0.05%, you are ahead of keeping cash in a drawer.

What if I need the money before interest is posted?

You can withdraw your money at any time. Interest is calculated up to the day you withdraw, so you earn a pro-rated amount for the partial month. You do not lose interest by withdrawing early.

Do I have to have a minimum balance to earn interest?

It depends on the bank. Some require a minimum balance, some do not. Some waive the minimum if you set up direct deposit. Check your bank's terms before opening an account if the minimum matters to you.
