What you earn depends on the bank and the account type
The amount of interest you earn in a savings account is not fixed — it changes based on where you bank and what kind of account you open. A bank decides its own interest rate, so two banks might offer very different amounts for the same type of account. The rate also moves up and down over time as the Federal Reserve changes its benchmark interest rate, which influences what all banks offer.
Right now, savings accounts at online banks often pay more interest than accounts at brick-and-mortar banks in your neighborhood. A traditional savings account at a local bank might earn 0.01% per year, while an online savings account might earn 4% or 5% per year — a difference that matters a lot if you have money sitting there for months or years. High-yield savings accounts are the online accounts that pay the higher rates.
The interest rate a bank advertises is called the Annual Percentage Yield, or APY. This is the percentage of your balance you will earn over one year if you do not add or withdraw money. If you have $1,000 in an account earning 4% APY, you will earn about $40 in interest over twelve months.
Key Takeaways
- Online banks typically offer higher interest rates (4% to 5% APY) than traditional banks (0.01% to 0.5% APY), though rates change frequently.
- The interest rate is shown as APY, which tells you what percentage of your balance you will earn in one year.
- Your bank compounds interest, meaning you earn interest on your interest, though how often this happens varies by bank.
- The Federal Reserve's decisions affect what all banks offer, so rates rise and fall over time — there is no permanent "best" rate.
- Money market accounts and certificates of deposit sometimes pay more than savings accounts, but they have different rules about withdrawals.
How banks calculate and add your interest
Banks do not wait until the end of the year to give you all your interest at once. Instead, they calculate and add interest regularly — usually daily or monthly — and that process is called compounding. When interest is compounded, you earn interest on the interest you already earned, which means your balance grows faster than it would if the bank just added one lump sum at the end of the year.
Here is a straightforward example: if you have $1,000 earning 4% APY and the bank compounds daily, it divides the 4% by 365 days and adds a tiny bit of interest each day. After one month, you might have $1,003.27. The next month, the bank calculates interest on $1,003.27, not just the original $1,000. By the end of the year, you will have earned slightly more than $40 because of compounding.
Most banks compound daily or monthly, and they tell you which one in the account details. Daily compounding earns you a little more money, but the difference is usually small — a few dollars per year on a typical balance. What matters much more is the APY itself: a 4% APY with monthly compounding will earn you far more than a 0.5% APY with daily compounding.
Why rates are higher at online banks
Online banks pay more interest because they have lower costs. They do not rent physical buildings, pay as many employees, or maintain ATM networks. Because their expenses are lower, they can pass more of their profits to customers in the form of higher interest rates. A bank still makes money — it borrows from you at 4% APY and lends that money to other customers at higher rates — but online banks can afford to be more generous.
Traditional banks in your town pay less interest partly because they have higher costs, but also because they know many customers will stay with them for convenience. You can walk in, talk to a person, and use their ATM. Online banks have no physical location, so they compete mainly on interest rate. If they do not offer a high rate, there is no reason to bank with them.
This does not mean online banks are risky. Most are insured by the FDIC (Federal Deposit Insurance Corporation), the same government agency that insures traditional banks. Your money is protected up to $250,000 per account type at any FDIC-insured bank, whether it is online or in person.
How the Federal Reserve affects what you earn
The Federal Reserve, which is the central bank of the United States, sets a benchmark interest rate that influences what all banks offer. When the Fed raises its rate, banks raise the interest they pay on savings accounts. When the Fed lowers its rate, banks lower what they pay you. This is why the rates you see today might be different from the rates you saw six months ago.
You cannot control what the Fed does, but you can understand that rates will change. If you see a 5% APY today, that rate might drop to 4% next year if the Fed lowers its benchmark rate. This is not the bank being unfair — it is how the whole system works. The bank is not promising to pay you 5% forever; it is promising to pay you the APY shown on the day you open the account, and that rate can change.
Comparing savings accounts, money market accounts, and CDs
A savings account lets you withdraw money whenever you want without penalty. A money market account is similar but usually requires a higher opening balance and pays slightly more interest. A certificate of deposit, or CD, locks your money away for a set time — usually three months to five years — and pays more interest in exchange for that lock-in period.
If you need access to your money, a savings account or money market account is the right choice. If you have money you will not need for a year or more, a CD might earn you more. For example, a savings account might pay 4% APY, while a one-year CD at the same bank might pay 4.5% or 5% APY. The catch is that if you withdraw from a CD before the time is up, you pay an early withdrawal penalty, usually a few months' worth of interest.
The table below shows how these accounts typically compare:
| Account Type | Typical APY Range | Withdrawal Rules | Best For |
|---|---|---|---|
| Traditional Savings | 0.01% to 0.5% | Withdraw anytime | straightforward access, low risk |
| High-Yield Savings | 4% to 5% | Withdraw anytime | Building emergency funds |
| Money Market Account | 4% to 5% | Limited withdrawals per month | Higher balance, some restrictions OK |
| Certificate of Deposit | 4.5% to 5.5% | Locked for set term | Money you will not need soon |
What happens to your interest if you withdraw money
If you withdraw money from a savings account before the end of the year, you do not lose the interest you already earned — you keep it. But you stop earning interest on the money you withdrew. For example, if you have $1,000 earning 4% APY and you withdraw $500 after six months, you keep the interest you earned on the full $1,000 for those six months, but for the rest of the year you only earn interest on the remaining $500.
Money market accounts sometimes have limits on how many times you can withdraw per month without a fee. If you exceed that limit, the bank charges you a fee, usually $10 to $25 per extra withdrawal. This is why money market accounts are better for money you will not touch often.
How to find the current rates at different banks
Interest rates change frequently, so there is no point in listing specific numbers here — they will be outdated within weeks. Instead, you can check rates yourself by visiting bank websites directly. Most banks show their current APY on the savings account page, usually near the "Open an Account" button.
Websites like Bankrate, DepositAccounts, and NerdWallet compare rates across many banks and update them regularly. You can search by account type — savings, money market, or CD — and see which banks are paying the most right now. These comparison sites do not charge you; they make money from banks that pay them for referrals.
When you compare rates, look at the APY, not just the interest rate. APY includes the effect of compounding, so it is the true number that tells you what you will earn. Also check whether the bank requires a minimum opening balance or a minimum balance to earn the advertised rate — some banks pay the high rate only if you keep a certain amount in the account.
Frequently Asked Questions
Is the interest I earn taxed?
Yes. Interest earned in a savings account is considered income by the IRS. At the end of the year, your bank sends you a form called a 1099-INT that reports how much interest you earned. You report this on your tax return. The amount of tax you owe depends on your total income and tax bracket, but you will owe something if you earned interest.
Can I move my money to a different bank if rates drop?
Yes. You can withdraw your money from one bank and deposit it at another bank with a higher rate. There is no penalty for moving your savings account. The only accounts with early withdrawal penalties are CDs. If you move money out of a CD before the term ends, you pay a penalty, but you can move money out of a savings account anytime without cost.
What if I keep adding money to my savings account?
The bank calculates interest on your balance each day, so as you add money, you earn interest on the new deposits too. If you start with $1,000 and add $100 per month, the bank compounds interest on $1,000 the first month, $1,100 the second month, and so on. This is why regular deposits to a savings account grow faster than a single lump sum.
Why do some banks offer 0% interest?
Banks that offer 0% or very low interest (like 0.01%) are usually traditional banks with physical locations. They rely on convenience and customer loyalty rather than competing on rate. If you have money in an account earning 0.01%, moving it to an online bank earning 4% or 5% will earn you hundreds of dollars per year on a typical balance.
Does the interest rate ever go negative?
In the United States, banks do not charge you to hold money in a savings account — your balance will never shrink because of negative interest. In some countries, banks do charge negative rates, but that does not happen here. Your savings account will always earn at least 0%, even if the rate is very low.
