Yes, most savings accounts earn interest, but the rate varies widely by bank and account type

Interest on a savings account is money the bank pays you for keeping your money with them. The bank lends out deposits to other customers and uses the interest those borrowers pay to fund what they pay you. The amount you earn depends on three things: how much money you have in the account, how long it stays there, and the annual percentage yield (APY) the bank offers.

Not every savings account earns the same rate. A high-yield savings account at an online bank might pay 4% to 5% APY right now, while a traditional savings account at a brick-and-mortar bank might pay 0.01% APY. The difference between those two rates means $1,000 earning $40 to $50 per year versus $1,000 earning 10 cents per year. The rate also changes over time—when the Federal Reserve raises or lowers interest rates, banks adjust what they pay depositors.

Key Takeaways

  • Interest rates on savings accounts range from nearly zero at traditional banks to 4% or higher at online banks, and the rate your bank offers can change at any time.
  • Interest compounds, meaning you earn money on the interest you already earned, so the longer your money sits untouched, the more it grows.
  • The Federal Deposit Insurance Corporation (FDIC) insures up to $250,000 per account holder per bank, so your principal is protected even if the bank fails.
  • Money market accounts and certificates of deposit (CDs) often pay higher rates than regular savings accounts, but may have withdrawal limits or require you to lock money away for a set time.

How interest compounds and why time matters

Interest compounds, which means you earn interest on the interest you already earned. If your account pays 4% APY and you have $1,000, after one year you have $1,040. The next year, the bank pays 4% on $1,040, not just the original $1,000, so you earn $41.60 instead of $40. The longer your money stays in the account, the more this compounding effect adds up.

Most banks compound interest daily or monthly. Daily compounding means the bank calculates and adds interest to your balance every single day, so your balance grows slightly faster than with monthly compounding. The difference is small on small balances but becomes noticeable on larger amounts or over many years. Your bank's account disclosure will tell you how often they compound.

Where to find your bank's current interest rate

Your bank publishes its APY on its website, usually on the savings account product page. You can also call the bank or visit a branch and ask. The rate shown is the rate new customers get when they open an account today—existing customers may have a different rate, especially if they opened their account years ago.

If you want to compare rates across banks, websites like Bankrate, DepositAccounts, and the Federal Deposit Insurance Corporation's (FDIC) National Rates and Rate Caps search tool show current rates from multiple banks. These sites update regularly as banks change their rates. Keep in mind that the highest-paying accounts are usually at online-only banks, which have lower overhead costs than banks with physical branches.

The difference between savings accounts, money market accounts, and CDs

A regular savings account lets you deposit and withdraw money whenever you want, with no penalty. The tradeoff is that the interest rate is usually lower than other savings products. A money market account often pays a higher rate but may limit how many withdrawals you can make per month (usually six) and may require a higher minimum balance to open. A certificate of deposit (CD) pays the highest rate of the three, but you agree to leave your money untouched for a set period—three months, six months, one year, or longer. If you withdraw before that time is up, you pay a penalty, usually a few months' worth of interest.

Which one makes sense depends on whether you need access to your money. If you might need it within the next year, a regular savings account or money market account is safer. If you know you won't touch the money for a year or more, a CD locks in a may provide rate and usually pays more. Some people use a CD ladder—opening multiple CDs that mature at different times—so they have access to some money each year while keeping rates higher than a regular savings account.

How FDIC insurance protects your money

The FDIC insures deposits at member banks up to $250,000 per depositor per bank. This means if the bank fails, the FDIC will reimburse you for your balance up to that limit. Your interest earnings are included in that $250,000 limit, not separate from it. If you have $250,000 in a savings account earning 4% APY, the interest you earn is part of the insured amount, not extra.

If you have more than $250,000 to save, you can spread it across multiple banks to keep everything insured. For example, $250,000 at Bank A and $250,000 at Bank B are both fully insured. You can also open a joint account with another person—that gets its own $250,000 of coverage separate from your individual accounts at the same bank. The FDIC website has a calculator that shows you exactly how much of your money is covered.

What happens if your bank lowers its interest rate

Banks can change the interest rate on savings accounts at any time, and they usually announce the change in writing or on their website. When rates fall, your earnings drop immediately—there is no grace period. When rates rise, your earnings go up, but only on new deposits or after the bank updates your account rate. You are not locked into a rate on a regular savings account the way you are with a CD.

If your bank's rate drops significantly and you have a large balance, it may be worth moving your money to a bank paying a higher rate. The process is simple: open an account at the new bank, then transfer your money over. There is no penalty for moving money out of a savings account. Some people check rates once or twice a year and move their money if they find a better deal elsewhere.

How to calculate what you will earn

You can estimate your interest earnings using a simple formula or an online calculator. The formula is: Balance × APY ÷ 365 × number of days. If you have $5,000 in an account paying 4% APY, that is $5,000 × 0.04 ÷ 365 × 365 = $200 per year. Most banks and financial websites offer savings calculators where you enter your balance, the APY, and how long you plan to keep the money, and the calculator shows you the total with compounding included.

Keep in mind that interest earnings are taxable income. At the end of the year, your bank sends you a 1099-INT form showing how much interest you earned, and you report that on your tax return. If you earned more than $10 in interest during the year, the bank is required to send you the form. Even if you earned less, you still need to report it.

Frequently Asked Questions

Can I lose money in a savings account?

Your principal is protected by FDIC insurance, so you cannot lose the money you deposited. However, if inflation is higher than your interest rate, your money loses purchasing power—it buys less than it did before. If your account pays 0.5% APY and inflation is 3%, you are effectively losing 2.5% in value per year, even though your account balance is higher.

Why do online banks pay more interest than traditional banks?

Online banks have lower costs because they do not operate physical branches or employ as many staff. They pass those savings to customers by paying higher interest rates on deposits. The tradeoff is that you cannot walk into a branch to deposit cash or speak to someone in person—everything is done online or by phone.

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

Rates change constantly as banks respond to Federal Reserve decisions and market conditions. High-yield savings accounts currently range from about 4% to 5% APY, but this varies by bank and changes frequently. Check sites like Bankrate or DepositAccounts to see current rates from multiple banks.

Does my interest get taxed?

Yes, interest earnings are taxable as ordinary income. Your bank reports the amount on a 1099-INT form at the end of the year. You include this on your tax return. The tax rate depends on your overall income and tax bracket.

Can I move my money to a different bank without losing interest?

Yes. Interest accrues daily, so you earn interest right up until the day you withdraw. When you move to a new bank, you start earning interest at the new rate immediately. There is no penalty or loss for switching banks on a savings account.
