You earn interest on a savings account; the bank does not charge you interest
A savings account pays you interest on the money you deposit. The bank holds your cash and lends it out to other customers; in exchange, they pay you a small percentage of your balance each month or year. You never pay interest on a savings account — that would be a loan, not a savings product.
How much interest you earn depends on the account's annual percentage yield (APY), which varies by bank and changes over time. A bank offering 0.01% APY will pay you almost nothing. A bank offering 4.5% APY will pay roughly four hundred times more on the same balance. The difference between these two is real money, especially if you keep a large balance or leave it untouched for years.
Interest compounds, meaning you earn interest on your interest. If you deposit $1,000 at 4.5% APY and never touch it, after one year you will have $1,045. After two years, you will have $1,092 — the extra $47 came from interest earned on the first year's interest. Over decades, this compounds into meaningful growth.
Key Takeaways
- Banks pay you interest on savings account balances; you never pay interest to hold a savings account.
- The annual percentage yield (APY) is the rate the bank offers, and it varies widely — from under 0.01% to over 5% depending on the bank and current economic conditions.
- Interest compounds monthly or daily at most banks, so you earn interest on interest, which accelerates growth over time.
- Online banks typically offer higher APY than brick-and-mortar banks because they have lower overhead costs.
- The Federal Reserve's interest rate decisions affect how much banks are willing to pay you, so APY rises and falls with the broader economy.
Why APY varies so much between banks
Banks set their own APY based on what the Federal Reserve charges them to borrow money. When the Fed's rate is high, banks can afford to pay depositors more. When the Fed's rate is low, banks pay less. But banks also compete for deposits, so a bank that wants to attract new customers will offer a higher rate than its competitors.
Online banks almost always pay more than traditional banks. A Chase or Bank of America branch might offer 0.01% APY on a basic savings account, while an online bank like Marcus or Ally offers 4.0% or higher on the same type of account. The difference is overhead: online banks have no physical branches, no tellers, and lower staff costs, so they pass savings to depositors as higher rates.
Some banks also offer tiered rates, meaning the APY changes based on how much you have in the account. A bank might pay 0.5% on balances under $10,000 and 2.0% on balances above $100,000. Read the fine print before opening an account, because the advertised rate may only apply to a portion of your money.
How often interest is calculated and added to your account
Banks calculate interest either daily or monthly, but they add it to your account monthly or quarterly. The timing matters because daily compounding grows your money slightly faster than monthly compounding, even at the same APY.
Most online banks compound daily and credit interest monthly. This means the bank calculates what you owe every single day based on your current balance, but you see the money appear in your account once a month. A few banks credit interest daily, which is slightly better, but the difference over a year is usually just a few dollars on a typical balance.
You do not have to do anything to receive interest. It appears automatically. If you close the account or withdraw money mid-month, you typically forfeit interest on that portion for that period, though policies vary by bank.
How APY has changed in recent years
In 2022 and 2023, the Federal Reserve raised interest rates sharply to fight inflation. Savings account APY rose from near zero to 4% or higher at competitive banks. In 2024, rates have stabilized but remain elevated compared to the 2010s, when many accounts paid 0.01% or less.
If you opened a savings account years ago and have not checked the rate recently, you are likely earning far less than you could elsewhere. Banks do not automatically raise rates on old accounts when the market changes — they only raise rates to attract new customers. Switching to a higher-paying bank is free and takes about ten minutes.
Future rate changes depend on Federal Reserve decisions, which are tied to inflation and employment. If the Fed cuts rates, bank APY will fall. If the Fed raises rates again, APY will rise. No one can predict this with certainty, but you can check what rates are currently available by visiting bank websites or comparison sites.
The difference between APY and APR
APY (annual percentage yield) includes the effect of compounding and is what you will actually earn. APR (annual percentage rate) does not include compounding and is used mainly for loans and credit cards. On a savings account, always look at the APY, not the APR.
For example, a bank might advertise 4.5% APY. That means if you deposit $1,000 and leave it for a year, you will have $1,045. If a bank advertised 4.5% APR on a savings account (which would be misleading), the actual amount you earned would be slightly less because compounding was not included in the calculation.
What happens to interest if you withdraw money early
Withdrawing money from a savings account does not trigger a penalty or cost you interest — savings accounts have no withdrawal limits or early-withdrawal fees. However, you stop earning interest on the money you withdraw as soon as it leaves the account.
If you withdraw $500 from a $1,000 balance mid-month, you will earn interest only on the remaining $500 for that period. Some banks calculate interest based on your average daily balance for the month, so the exact amount you lose depends on when in the month you withdraw.
Money market accounts and certificates of deposit (CDs) are different. CDs charge a penalty if you withdraw before the term ends, and money market accounts may have withdrawal limits. A basic savings account does not.
How to find the highest APY for your situation
Start by checking rates at online banks like Marcus, Ally, American Express Personal Savings, and Discover. These typically offer 4.0% to 5.0% APY on basic savings accounts with no minimum balance. Then check your current bank's rate — you may be surprised how far behind it is.
If you have a very large balance (over $250,000), look into banks that offer tiered rates or money market accounts, which sometimes pay slightly more. If you want to keep your money at a bank with a physical branch, accept that you will earn less and decide whether the convenience is worth it.
Opening a new account at a higher-paying bank takes about ten minutes online. You will need your Social Security number, a government ID, and a way to fund the account (usually a transfer from another bank). There is no cost, and you can keep both accounts open at the same time.
Frequently Asked Questions
Do I have to pay taxes on savings account interest?
Yes. Interest earned on a savings account is taxable income. Banks send you a 1099-INT form each January if you earned $10 or more in interest during the year. You report this on your tax return. The higher the APY and the larger your balance, the more tax you will owe on the interest.
Can a bank lower my APY without warning?
Yes. Banks can change APY at any time without notice, though they usually announce changes on their website. If your rate drops and you do not like it, you can transfer your money to a different bank. There is no penalty for moving your savings.
What if the bank fails — do I lose my interest?
No. The FDIC insures savings accounts up to $250,000 per depositor per bank. If a bank fails, the FDIC pays you back in full, including any interest you earned up to the date of failure. Your money is protected.
Is a savings account better than keeping cash at home?
Yes, because you earn interest on a savings account and zero interest on cash. Even at 0.5% APY, a $10,000 balance earns $50 per year. At 4.5% APY, it earns $450 per year. Over time, this adds up, and you still have instant access to your money.
Why do some banks offer promotional rates that are higher than their regular rate?
Banks use promotional rates to attract new customers. The high rate usually lasts three to twelve months, then drops to the regular rate. Read the terms carefully — some promos require a minimum deposit or direct deposit to may have access to, and the rate may apply only to new money, not existing balances.
