A yield savings account pays you interest on the money you deposit, and the rate you earn depends on the Federal Reserve's current rate and your bank's decision to pass it along
When you put money in a regular savings account, the bank uses that money to lend to other customers and make investments. A yield savings account is the bank's way of sharing some of that profit with you. The bank pays you interest — a percentage of your balance — for letting them use your money. The percentage is called the annual percentage yield, or APY.
The APY you see advertised is what you would earn if you left your money untouched for a full year. If a bank offers 4.50% APY and you have $10,000 in the account, you would earn roughly $450 over twelve months (the exact amount depends on how the bank compounds the interest — daily, monthly, or quarterly). The higher the APY, the more you earn. The catch is that APY changes. When the Federal Reserve raises or lowers its benchmark rate, banks adjust their APYs up or down within days or weeks.
Key Takeaways
- Interest in a yield savings account is calculated as a percentage of your balance and paid to you regularly — usually monthly or quarterly.
- The APY you see today may be different next month because banks adjust rates when the Federal Reserve moves its benchmark rate.
- Online banks typically offer higher APYs than brick-and-mortar banks because they have lower overhead costs.
- Your deposits are insured up to $250,000 per account owner per bank by the FDIC, so the interest you earn is on top of that protection.
How interest compounds and when you see the money
Banks calculate interest in different ways, and the method matters. Compounding means the bank pays interest on your interest. If your account compounds daily, the bank calculates what you owe every single day and adds it to your balance. The next day, it calculates interest on the new, larger balance. Over a year, daily compounding earns you slightly more than monthly or quarterly compounding on the same APY.
You do not see the interest when ready. Most banks deposit it into your account monthly, though some do it quarterly. When it lands, it becomes part of your balance and starts earning interest itself. If you withdraw money before the interest posts, you lose the interest that would have been calculated on that amount. Some banks also have promotional rates — a higher APY for a limited time, usually three to twelve months — so the rate you earn now may drop later.
Why APY varies so much between banks
All banks operate under the same Federal Reserve rate, but they do not all offer the same APY. Online banks — those with no physical branches — typically offer 4% to 5% APY, while traditional banks with branches often offer 0.01% to 0.50%. The difference is cost. A brick-and-mortar bank pays for buildings, staff, and ATM networks. An online bank has almost none of those expenses, so it can afford to pay you more of the interest it earns.
A bank's APY also depends on how much money it needs. During periods when banks have plenty of deposits, they lower their rates because they do not need to attract more customers. When deposits are scarce, they raise rates to compete. This is why you might see one online bank offer 4.75% while another offers 4.25% — both are responding to their own deposit needs, not to different Federal Reserve rates.
The difference between yield savings and money market accounts
A money market account is similar to a yield savings account but usually comes with a debit card and check-writing privileges. In exchange, it often has a higher minimum balance requirement — sometimes $2,500 or more — and may limit how many withdrawals you can make per month. A yield savings account has no withdrawal limits and usually no minimum balance, though some banks require $500 or $1,000 to open.
Both are FDIC-insured up to $250,000 and both earn interest. The choice depends on whether you need to access your money frequently. If you are building an emergency fund and want to touch it whenever you need to, a yield savings account is simpler. If you have a larger sum you do not plan to touch and want slightly higher interest, a money market account may be worth the restrictions.
How to compare APY across banks
The APY listed on a bank's website is the rate new customers see today, but it may change before you open the account. When you are comparing banks, look at the APY, the compounding method (daily is best), and whether there is a promotional rate involved. If the rate is promotional, ask how long it lasts and what the standard rate will be after.
Also check the minimum balance to open and whether the bank charges monthly fees. Some banks waive fees if you keep a certain balance or set up direct deposit. A bank offering 4.50% APY with a $25 monthly fee is worse than one offering 4.25% with no fee. Use a calculator to compare: multiply your expected balance by each APY, subtract any annual fees, and see which bank actually puts more money in your pocket over a year.
What happens to your interest if rates drop
When the Federal Reserve lowers its benchmark rate, banks lower their APYs within days. Your existing balance does not disappear — you keep every dollar you deposited and every dollar of interest you earned. But the interest you earn going forward will be lower. If you had $10,000 earning 4.50% and the rate drops to 3.50%, you will earn roughly $100 less per year on that same $10,000.
This is why some people move money between banks when rates change. If your current bank drops to 2.00% and another bank is offering 3.75%, you can withdraw your money and move it. There is no penalty for switching banks. The only cost is the time it takes to open a new account and transfer funds, which usually takes three to five business days.
FDIC insurance and what it covers
Every dollar you deposit in a yield savings account at an FDIC-insured bank is protected up to $250,000 per account owner per bank. This means if the bank fails, the government guarantees you get your money back. The interest you earn is also covered — it counts toward your $250,000 limit. If you have $240,000 in the account and earn $10,000 in interest, your total is $250,000, and all of it is insured.
If you have more than $250,000 to save, you can open accounts at different banks to keep everything insured. You can also open a joint account with another person — that gives you another $250,000 of coverage at the same bank, because the coverage is per account owner. A yield savings account is one of the safest places to keep money because you earn interest and your deposits are may provide.
Frequently Asked Questions
Do I have to keep a minimum balance to earn interest?
It depends on the bank. Some yield savings accounts have no minimum balance requirement and will pay interest on any amount, even $1. Others require $500 or $1,000 to open the account but then pay interest on whatever you have. Check the bank's terms before opening.
Can I withdraw money whenever I want without losing interest?
Yes. Yield savings accounts have no withdrawal limits. You can take money out anytime. The only thing you lose is the interest that would have been calculated on the amount you withdrew — you do not lose interest you already earned.
What happens to my interest if I close the account?
You keep all the interest you earned up to the day you close. The bank will pay it to you as part of your final withdrawal. Interest accrues right up until the account closes, so there is no penalty for leaving.
Is the interest I earn considered income for taxes?
Yes. Interest from a savings account is taxable income. Banks send you a 1099-INT form at the end of the year if you earned $10 or more in interest. You report this on your tax return. The more interest you earn, the more you may owe in taxes.
How often should I check my APY to see if it has changed?
Check once a month if rates are moving quickly, or every three months if they are stable. You can set a calendar reminder. If your bank's rate drops significantly below other banks, that is usually a good time to compare and consider moving your money.
