Yes, most savings accounts earn interest, but the rate and how often it compounds depends on your bank and the current economic environment

Interest is money your bank pays you for letting them hold your deposits. When you open a savings account, the bank uses your money to make loans and investments. In return, they share a portion of what they earn with you as interest. The amount you earn is calculated as a percentage of your balance, called the annual percentage yield (APY).

Not every savings account earns the same rate. Traditional banks often pay very little—sometimes less than 0.01% APY. Online banks and credit unions typically pay more, sometimes 4% to 5% APY or higher, depending on market conditions. The difference between a 0.01% rate and a 5% rate is enormous over time: on $10,000, you might earn $1 per year at the low end or $500 per year at the high end.

Your bank must disclose the APY before you open the account. This rate can change at any time, and banks often lower it when the Federal Reserve cuts interest rates. The rate you see today may not be the rate you earn next month.

Key Takeaways

  • Interest rates on savings accounts vary widely—online banks and credit unions often pay 10 to 50 times more than traditional banks.
  • The APY shown when you open an account can change, and banks typically lower rates when the Federal Reserve cuts rates.
  • Interest compounds, meaning you earn interest on your interest, but how often this happens (daily, monthly, quarterly) affects your total earnings.
  • Your deposits are insured up to $250,000 per account owner per bank through the FDIC, regardless of the interest rate.

How banks calculate and pay your interest

Banks calculate interest using your daily balance—the amount in your account each day. They add up all your daily balances for the month or quarter, divide by the number of days, and explore the APY to that average. This is why deposits made early in the month earn more than deposits made late.

Interest is compounded, which means you earn interest on your interest. If your account compounds daily, the bank calculates interest each day and adds it to your balance. The next day, you earn interest on both your original deposit and yesterday's interest. Compounding happens automatically—you do nothing. Daily compounding earns slightly more than monthly or quarterly compounding, but the difference is small unless your balance is very large.

Banks pay interest into your account on a schedule set by the bank. Some pay monthly, some quarterly, some annually. You can see how often your bank pays by checking your account agreement or asking customer service. The money appears as a deposit in your account, and you can withdraw it or leave it to compound.

Why interest rates change and what affects them

The Federal Reserve sets a target interest rate that influences what banks pay on savings. When the Fed raises rates, banks usually raise savings rates too. When the Fed cuts rates, banks cut savings rates. This happens because banks' own costs change, and they adjust what they pay depositors to stay competitive.

Market conditions also matter. During periods of high inflation or strong demand for loans, banks may offer higher rates to attract deposits. During recessions or when the Fed is cutting rates, rates fall. Rates that were 5% a year ago may be 3% today, or vice versa.

Your individual rate depends on the account type and your bank. A high-yield savings account at an online bank will almost always pay more than a regular savings account at a traditional bank. Money market accounts sometimes pay more than savings accounts, though they may require a higher minimum balance. Certificates of deposit (CDs) lock in a fixed rate for a set time period, protecting you from rate cuts but preventing you from accessing your money without penalty.

The difference between APY and APR

You may see both APY (annual percentage yield) and APR (annual percentage rate) mentioned. APY includes the effect of compounding, so it is always equal to or higher than APR. APY is what you actually earn on a savings account. APR is used for loans and credit cards and does not account for compounding in the same way.

Always compare savings accounts using APY, not APR. A savings account advertising 5% APY will earn you more than one advertising 5% APR, though most savings accounts use APY.

How to find accounts with higher interest rates

Online banks and credit unions typically offer the highest rates because they have lower overhead costs than traditional banks with physical branches. You can compare current rates on financial websites that track savings rates, though rates change frequently and the information may be a few days old.

When comparing accounts, look at the APY, any minimum balance requirements, and whether the rate is promotional (temporary) or standard. Some banks offer a higher rate for the first few months, then drop it. Read the account agreement to see whether the rate can change and how much notice the bank must give before lowering it.

Moving money between banks takes three to five business days via electronic transfer. If you find a higher rate elsewhere, you can open a new account and transfer your balance without penalty. Your FDIC insurance follows you—each account at each bank is insured separately up to $250,000.

What happens to interest if you withdraw money

Interest accrues daily based on your balance, so if you withdraw money mid-month, you lose interest on that amount for the rest of the month. If you deposit $5,000 on the first of the month and withdraw $2,500 on the 15th, you earn interest on $5,000 for 14 days and $2,500 for 16 days. The bank calculates this automatically.

Some savings accounts have withdrawal limits or require a minimum balance to earn the stated rate. Check your account agreement to see whether there are restrictions. Federal rules no longer cap the number of withdrawals you can make, but individual banks may charge fees if you exceed a certain number per month.

Interest and your taxes

Interest you earn is taxable income. If you earn $10 or more in interest during a calendar year, your bank will send you a Form 1099-INT in January. You report this on your tax return. The amount is small for most people, but it still counts as income.

You cannot deduct interest you earn on savings. You can only deduct interest you pay on certain loans, like mortgages or student loans. Keep your 1099-INT and any statements showing interest earned so you have documentation if the IRS asks.

Frequently Asked Questions

Can I lose money if interest rates fall?

No. Your principal—the money you deposited—is always yours. Interest rates affect how much new interest you earn going forward, not what you already have. If rates fall, your future interest payments will be smaller, but your account balance will not decrease.

Is my interest protected if the bank fails?

Yes. The FDIC insures deposits up to $250,000 per account owner per bank, including any interest that has been added to your account. If your bank fails, the FDIC pays you the full amount, including accrued interest.

Why do some banks pay almost no interest?

Traditional banks with many physical branches have higher costs and less incentive to compete on rate. Online banks have lower overhead and can pass savings to depositors. If your current bank pays less than 0.5% APY, you are likely losing money to inflation and could earn significantly more elsewhere.

Does moving my money to a higher-rate account cost anything?

No. Transferring between banks is free and takes three to five business days. You will not lose your FDIC insurance during the transfer. Some banks offer bonuses for opening new accounts with direct deposits, though these are separate from interest earnings.

What if I want to lock in a rate before it falls?

A certificate of deposit (CD) locks in a fixed rate for a set term—typically three months to five years. You cannot withdraw the money without paying a penalty, but your rate will not change. If you think rates are about to fall, a CD protects you, but you lose flexibility.
