Your savings account earns money through interest

A savings account makes money for you by paying interest — a percentage of the money you keep in the account. The bank uses your deposits to lend to other customers, and it shares a small portion of what it earns with you. The more money you keep in the account and the longer you keep it there, the more interest you earn.

The amount of interest varies widely. Some accounts pay almost nothing — less than 0.01% per year. Others pay 4% or 5% or higher, depending on the bank and the type of account. The difference between a low-paying account and a high-paying one can mean hundreds of dollars per year on the same balance, so where you keep your money matters.

Interest is usually calculated daily but paid monthly or quarterly. That means even if you only have money in the account for part of a month, you earn a small amount for those days. Over time, interest can also earn interest on itself — called compound interest — which makes your balance grow faster.

Key Takeaways

  • Banks pay interest on savings accounts as a percentage of your balance, and rates vary from nearly zero to 5% or higher depending on the bank and account type.
  • High-yield savings accounts typically pay much more interest than traditional savings accounts at the same bank, even though both are equally safe.
  • Online banks usually offer higher interest rates than brick-and-mortar banks because they have lower operating costs.
  • Interest is taxable income, so you will receive a tax form (1099-INT) at the end of the year if you earn more than a small amount.
  • Moving your money to a higher-paying account takes a few days but can earn you significantly more without any additional effort or risk.

High-yield savings accounts pay much more than regular savings accounts

A high-yield savings account is a savings account that pays a noticeably higher interest rate than a standard savings account. At many large banks, a regular savings account might pay 0.01% while a high-yield account at the same bank pays 4% or more. The accounts work the same way — you deposit money, it sits there safely, and you earn interest — but the rate is dramatically different.

High-yield accounts usually come with the same protections as regular savings accounts. Your money is insured by the FDIC (Federal Deposit Insurance Corporation) up to $250,000, meaning if the bank fails, the government guarantees your money back. You can withdraw your money whenever you need it, though some accounts limit how many withdrawals you can make per month without a fee.

The catch is that high-yield accounts often require a higher opening deposit — sometimes $500 or $1,000 or more — and some have monthly fees if your balance drops below a certain level. Read the account details carefully before opening one, because a high interest rate can be offset by fees that eat into your earnings.

Online banks typically offer higher rates than traditional banks

Online banks — banks with no physical branches, only a website and app — almost always pay higher interest rates than traditional banks you can walk into. This is because they have much lower costs. They do not pay for buildings, tellers, or the staff to run them. They pass those savings on to customers in the form of higher interest rates.

Online banks are just as safe as traditional banks. They are regulated by the same government agencies, and your deposits are insured by the FDIC the same way. You can deposit money by transferring it from another bank account, mailing a check, or using mobile check deposit. Withdrawing money takes a few business days because the transfer has to go through the banking system, but you can also use ATMs at partner networks if you need cash quickly.

Some online banks are subsidiaries of large traditional banks — for example, Marcus is owned by Goldman Sachs — while others are independent. Both types are legitimate. The main trade-off is convenience: you cannot walk in and talk to someone in person, but you can usually reach customer service by phone or chat.

How to compare interest rates and find the best account for you

Interest rates change frequently, sometimes weekly. Before opening any account, check the current rate on the bank's website. Look for the APY (Annual Percentage Yield), which is the rate you will actually earn over a year including compound interest. Do not compare just the interest rate alone — APY is the number that matters.

Write down the APY, any minimum opening deposit, any monthly fees, and any limits on withdrawals. Then check at least three other banks — including at least one online bank — and compare. A difference of 1% or 2% on a $10,000 balance means $100 to $200 per year. On a $50,000 balance, it means $500 to $1,000 per year.

Websites like Bankrate, DepositAccounts, and the Federal Reserve's National Information Center let you search current rates across many banks at once. These sites do not sell the accounts themselves — they just show you what is available — so you can use them to narrow your choices before going to a bank's website to open an account.

Moving money to a higher-paying account

If you already have a savings account at a bank that pays very little interest, you can move your money to a higher-paying account without losing anything. The process is straightforward: open a new account at the bank offering the better rate, then transfer your balance from the old account to the new one.

Most banks let you transfer money electronically between accounts at different banks. You will need the account number and routing number of your old account, which you can find on a check or by logging into your old bank's website. The transfer usually takes three to five business days. During that time, your money is in transit but still safe — it is not sitting unprotected anywhere.

Once the money arrives in the new account, you can close the old account if you want. Some people keep both accounts open — one for everyday spending and one for savings — but you do not have to. If you close the old account, make sure you have moved all the money out first and that no automatic payments are still being drawn from it.

Understanding how interest is taxed

Interest you earn on a savings account is taxable income. At the end of each year, the bank sends you a form called a 1099-INT that reports how much interest you earned. You include this amount on your tax return, and you owe income tax on it at your normal tax rate.

If you earn less than $10 in interest in a year, the bank usually does not send you a 1099-INT, but you still owe tax on it if you file a return. If you earn more than a small amount — the exact threshold varies by year — the bank is required to send the form. Keep your own records of interest earned in case there is a discrepancy.

This means that while interest is real money, it is not "free" in the sense that you do not owe tax on it. A 5% interest rate on $10,000 earns $500 in interest, but if you are in the 22% tax bracket, you owe about $110 in taxes on that $500, leaving you with about $390 in actual gain. This is still worthwhile — you are still earning money — but it is worth understanding that the interest rate shown is before taxes.

Money market accounts and certificates of deposit as alternatives

If you want to earn more interest than a savings account pays, you have other options beyond just switching to a high-yield savings account. A money market account is a hybrid between a checking account and a savings account. It usually pays interest similar to a high-yield savings account but lets you write checks or use a debit card, making it easier to access your money.

A certificate of deposit (CD) is an account where you agree to leave your money untouched for a set period — three months, six months, one year, five years, or longer. In exchange, the bank pays you a higher interest rate than it would for a regular savings account. If you withdraw the money before the term ends, you pay a penalty, usually a few months' worth of interest. CDs make sense if you know you will not need the money for a specific period and want to lock in a higher rate.

Both of these accounts are FDIC-insured like savings accounts, so your money is equally safe. The trade-off is flexibility: money market accounts may have higher fees, and CDs penalize you for early withdrawal. Choose based on whether you might need the money before the term ends.

Frequently Asked Questions

How much money do I need to earn a meaningful amount of interest?

At a 5% interest rate, you earn about $5 per month on a $1,200 balance. Most people find interest meaningful once they have at least $5,000 to $10,000 in savings, but even smaller amounts earn something. Every dollar earns interest, so there is no minimum threshold — it just becomes noticeable faster with larger balances.

Can I lose money in a savings account?

No. Your balance can only stay the same or grow. Interest is added to your account; nothing is subtracted. The FDIC insurance means even if the bank fails, you get your money back. The only way your balance shrinks is if you withdraw money yourself or if fees are charged and exceed your interest earnings.

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

You still earn interest for the days your money was in the account. Interest is calculated daily, so if you deposit $1,000 on the 15th and withdraw it on the 20th, you earn interest for those five days. You do not lose any interest by withdrawing early.

Should I move my money every time a bank raises its rate?

Not necessarily. Moving money takes a few days and can be inconvenient. If your current bank raises its rate to match competitors, there is no reason to move. If your rate falls significantly behind — more than 1% lower than what other banks are paying — it may be worth moving. Check rates once or twice a year and move only if the difference is substantial enough to justify the effort.

Is a savings account the best place for money I might need in an emergency?

Yes. A savings account is safe, your money is accessible within a few days, and you earn interest while you wait. This makes it better than keeping cash at home, which earns nothing. Keep three to six months of living expenses in a savings account for emergencies, and keep it in a high-yield account so it earns money while you are not using it.
