Interest is money your bank pays you for keeping money in your account

When you deposit money into a savings account, the bank lends that money to other customers through mortgages, auto loans, and business lines of credit. In exchange for the use of your money, the bank pays you interest—a percentage of your balance, calculated and added to your account on a schedule the bank sets. The interest rate your bank offers depends on the Federal Reserve's current rate, how much competition exists in your area, and what type of account you hold.

Interest accrues differently depending on the account. Most savings accounts compound interest daily or monthly, meaning the bank calculates interest on your balance plus any interest already earned. A few accounts compound annually. The more often interest compounds, the more you earn, though the difference is usually small on balances under $10,000.

You do not have to do anything to earn interest once your account is open. The bank calculates and deposits it automatically on the schedule they publish in your account agreement—usually monthly or quarterly. You can watch your balance grow in your online banking portal or monthly statement.

Key Takeaways

  • Banks pay interest on savings accounts because they lend your deposits to other customers and share a portion of the profit with you.
  • The interest rate you receive depends on Federal Reserve policy, your bank's competition, and the type of account you choose.
  • Interest compounds on a schedule set by your bank—daily, monthly, or quarterly—and the more often it compounds, the more you earn.
  • High-yield savings accounts and money market accounts typically pay significantly more interest than standard savings accounts at the same bank.
  • Moving your money to a different bank or account type is the most direct way to increase interest earned, since your current bank's rate is fixed.

How banks set the interest rate they offer you

Your bank's savings rate is tied to the federal funds rate, which the Federal Reserve sets roughly every six weeks. When the Fed raises its rate, banks eventually raise the rates they offer on savings accounts. When the Fed lowers its rate, banks lower savings rates. The lag between a Fed change and your bank's change can be weeks or months.

Beyond the Fed's rate, your bank also considers how much competition it faces. Banks in areas with many competitors or those that advertise nationally often offer higher rates to attract deposits. A large national bank with branches everywhere may offer 0.01% interest, while an online-only bank in the same month might offer 4.50% or higher. The difference is not about the bank's generosity—it is about how much they need your money.

Your specific account type also matters. A standard savings account at your bank might pay 0.01%, while a high-yield savings account at the same bank pays 4.25%. Money market accounts sometimes pay slightly more than high-yield savings. Checking accounts almost never pay meaningful interest. The bank publishes these rates in your account agreement and on their website, and they can change at any time without notice.

The difference between standard and high-yield savings accounts

A standard savings account is what most people have at their primary bank. It offers straightforward access to your money, no monthly fees (usually), and interest that is often so low it barely keeps pace with inflation. On a $5,000 balance, a standard account paying 0.01% earns about 50 cents per year.

A high-yield savings account pays significantly more—currently between 4% and 5.35% depending on the bank and the month. On the same $5,000 balance, a high-yield account earning 4.5% generates about $225 per year. The catch is that high-yield accounts are usually offered by online banks or credit unions, not by traditional brick-and-mortar banks. You access your money through an app or website, not a local branch. Some high-yield accounts have monthly minimums ($500 to $2,500) or require direct deposit to earn the advertised rate.

Money market accounts sit between the two. They often pay rates close to high-yield savings (currently 4% to 5%) but may include a debit card or limited check-writing, making them feel more like a checking account. They sometimes require higher minimums—$2,500 to $10,000—and may limit how many withdrawals you can make per month without a fee.

How to compare rates and move your money

The easiest way to earn more interest is to move your savings to a bank or account type that pays more. Start by checking what your current bank pays on its savings account—look at your account agreement or call the customer service number on your debit card. Then visit the websites of online banks like Marcus, Ally, American Express Personal Savings, or Discover to see their current rates. Credit unions also publish rates on their websites, though you must be a member to open an account.

Once you find an account that pays more, opening it takes 10 to 15 minutes online. You will need your Social Security number, a government ID, and proof of address (a recent utility bill or bank statement). The new bank will ask whether you want to transfer money from your old account. If you say yes, provide your old account number and routing number, and the new bank handles the transfer—usually within three to five business days.

You do not have to close your old account when ready. Many people keep their original savings account for emergencies or to maintain a relationship with their primary bank, then move most of their savings to the higher-paying account. There is no penalty for having accounts at multiple banks.

What happens to interest when rates fall

When the Federal Reserve lowers its rate, banks lower the interest they pay on savings accounts within weeks or months. If you are earning 4.5% and the Fed cuts rates, your bank may drop you to 3.8% or lower. Your balance does not shrink—you straightforward earn less on new interest going forward.

This is why comparing rates regularly matters. Every few months, check what your current bank is paying and what competitors are offering. If a competitor is paying 0.5% or more above your bank, moving your money takes less than an hour and can earn you hundreds of dollars per year on a large balance.

Some people move their money multiple times as rates shift. This is not risky or unusual—banks expect it. The only cost is the time it takes to initiate a transfer and wait for it to complete.

How interest is taxed

Interest you earn on a savings account is taxable income. Your bank will send you a Form 1099-INT each January showing how much interest you earned the previous year. You report this amount on your federal tax return, and you owe income tax on it at your regular tax rate.

If you earned less than $10 in interest during the year, your bank may not send a 1099-INT, but you still owe tax on the interest if you earned any. Keep your own records of interest earned if your bank does not send the form.

The tax is owed whether the interest sits in your account or you withdraw it. There is no way to avoid the tax, but you can reduce the amount of tax by earning interest in a tax-advantaged account like a Roth IRA or traditional IRA if you are saving for retirement. Those accounts have contribution limits and withdrawal rules, so they are not right for all savings, but they shield interest from federal income tax.

Frequently Asked Questions

Can I earn interest on a checking account?

Most checking accounts pay zero or near-zero interest. A few banks offer checking accounts with interest rates between 0.5% and 2%, but they usually require a high balance ($10,000 or more), direct deposit, or a minimum number of debit card transactions per month. For most people, a checking account is for spending and a savings account is for interest.

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

Rates change weekly based on Federal Reserve policy and bank competition. As of early 2024, high-yield savings accounts and money market accounts pay between 4% and 5.35%. Check the websites of online banks directly for current rates—comparison sites sometimes lag behind actual rates by a day or two.

Does moving my money to a new bank hurt my credit score?

No. Opening a savings account or moving money between banks does not affect your credit score. Banks do not report savings account activity to credit bureaus. Only credit products like loans and credit cards appear on your credit report.

What happens to my interest if I withdraw money mid-month?

Interest is calculated on your balance at the time the bank processes it, usually at the end of the month. If you withdraw money before that date, the interest calculation uses your lower balance. Some banks calculate interest daily and compound it, so you earn interest on the money for the days you held it, even if you withdraw it before month-end.

Is my interest safe if the bank fails?

Yes. The Federal Deposit Insurance Corporation (FDIC) insures savings accounts up to $250,000 per depositor per bank. If your bank fails, the FDIC pays you back the full amount, including all interest earned. Credit unions are insured by the National Credit Union Administration (NCUA) up to the same limit. This protection applies whether your account earns 0.01% or 5%.
