What you actually earn depends on the bank, the account type, and the rate environment

Banks do not all pay the same interest on savings accounts. The amount you earn depends on three things: which bank you use, what kind of savings account you open, and what the annual percentage yield (APY) is at that moment. A savings account at one bank might pay 0.01% APY while another pays 4.5% APY for the same type of account. The difference between those two rates means you earn 450 times more interest at the second bank.

Interest rates change constantly. Banks raise and lower their rates based on what the Federal Reserve does and how much competition they face for deposits. A rate that is competitive today may be outdated in three months. You do not lock in a rate when you open a savings account — the bank can change it whenever they want, though they must notify you first.

The amount you earn also depends on how much money you keep in the account and how long it stays there. A bank calculates interest daily but usually pays it monthly. If you deposit $10,000 at 4% APY, you earn roughly $400 per year, or about $33 per month. If you deposit $1,000 at the same rate, you earn $10 per year.

Key Takeaways

  • Interest rates on savings accounts vary by bank and change frequently, ranging from under 0.1% to over 4% APY depending on current market conditions.
  • Online banks typically pay higher rates than brick-and-mortar banks because they have lower overhead costs.
  • High-yield savings accounts pay more interest than regular savings accounts at the same bank, but both rates can change at any time.
  • Your bank must notify you before lowering your rate, but you can move your money to a different bank if the new rate is too low.
  • The interest you earn is taxable income and must be reported on your tax return.

How banks decide what rate to offer

Banks set their savings rates based on the federal funds rate, which is the interest rate the Federal Reserve charges banks to borrow from each other. When the Fed raises its rate, banks eventually raise the rates they pay on savings. When the Fed lowers its rate, banks lower savings rates too. The lag between a Fed change and a bank's response can be weeks or months.

Competition also matters. If a bank is trying to attract more deposits, it raises its savings rate to make itself more attractive. If a bank has plenty of deposits already, it may lower its rate because it does not need to compete as hard. Online banks often pay higher rates than traditional banks because they operate with fewer physical branches and lower costs, so they can afford to pass more interest to depositors.

The type of account also affects the rate. A regular savings account at a bank typically pays less than a high-yield savings account at the same bank. Money market accounts sometimes pay more than regular savings but less than high-yield accounts. Certificates of deposit (CDs) lock your money away for a set time and usually pay more than any savings account, but you cannot withdraw the money early without a penalty.

What rates look like right now across different account types

Rates vary widely depending on where you bank. As of early 2024, a regular savings account at a large national bank might pay 0.01% to 0.05% APY. A high-yield savings account at an online bank might pay 4% to 4.5% APY. A money market account could pay anywhere from 0.1% to 4.75% APY. A one-year CD might pay 4.5% to 5.3% APY. These numbers change frequently, sometimes weekly.

The difference between a low-paying account and a high-paying one compounds over time. If you keep $50,000 in a regular savings account paying 0.01% APY, you earn $5 per year. If you move that same $50,000 to a high-yield account paying 4.5% APY, you earn $2,250 per year. Over five years, that is a difference of $11,225 in interest earned.

You can find current rates by visiting bank websites directly or using rate comparison sites that track savings rates across multiple banks. Most banks display their APY prominently on their savings account pages. The APY already includes the effect of compounding, so it is the number to compare when deciding between accounts.

How interest compounds and when you receive it

Banks calculate interest daily but typically pay it monthly. Compounding means the bank pays interest on your interest. If you earn $10 in interest one month, the next month you earn interest on the original balance plus that $10. Over time, compounding makes your money grow faster, especially at higher rates.

Most savings accounts compound daily and pay monthly. Some accounts compound and pay quarterly or annually. The more frequently interest compounds, the more you earn, though the difference is usually small. An account that compounds daily and pays monthly will earn slightly more than one that compounds and pays quarterly, all else equal.

You receive interest as a deposit into your account. You can withdraw it, spend it, or leave it there to compound further. The bank reports the interest you earn to the IRS on a Form 1099-INT if you earn $10 or more in a calendar year. You must report this interest as income on your tax return.

Why some banks pay much more than others

Online banks pay higher rates because they have lower costs. They do not maintain physical branches, do not employ as many tellers, and do not pay for as much real estate. Those savings get passed to depositors in the form of higher interest rates. A bank like Ally or Marcus can afford to pay 4.5% APY because they spend far less on operations than a bank like Chase or Bank of America.

Large national banks often pay lower rates because they have a captive customer base. People keep money at Chase or Wells Fargo partly out of habit or convenience, not because of the interest rate. These banks do not need to compete as aggressively on rate to keep deposits. Smaller regional banks fall somewhere in between — they pay more than the largest banks but usually less than pure online banks.

Credit unions sometimes pay higher rates on savings accounts than banks do, though not always. Credit unions are member-owned and not-for-profit, so they can return earnings to members in the form of higher rates. However, credit unions vary widely in their rates and products, so you still need to shop around.

What happens when rates change

Banks can raise or lower your savings rate at any time. They must notify you before lowering the rate, usually by email or mail, and the change takes effect after a waiting period — often 30 days. They do not need to ask your permission. If you do not like the new rate, you can move your money to a different bank.

When the Federal Reserve raises rates, banks usually raise their savings rates within a few weeks. When the Fed lowers rates, banks often lower savings rates faster. This asymmetry means you benefit quickly when rates go up but lose out quickly when they go down. If you lock in a high rate at one bank, that rate will eventually fall as the Fed cycle changes.

You do not lose any money when a rate drops — you just earn less interest going forward. Your principal balance stays the same. If you had $10,000 earning 4.5% and the rate drops to 2%, you still have $10,000, but you now earn less each month.

How to find the best rate for your situation

Start by deciding what you need the money for. If you need access to it within the next year, a high-yield savings account or money market account makes sense. If you can lock the money away for one to five years, a CD usually pays more. If you might need it in the next few months, a regular savings account is safer even if the rate is lower.

Once you know the account type, compare rates across banks. Visit the websites of online banks like Ally, Marcus, Wealthfront, and Vanguard. Check rates at your current bank. Look at credit unions if you are a member. Use a rate comparison tool to see multiple banks at once. Write down the APY, any minimum balance requirements, and any fees.

Pay attention to minimum balance requirements. Some banks pay their advertised rate only if you maintain a certain balance — often $25,000 or more. If your balance falls below that, the rate drops. Read the fine print before opening an account. Also check whether the bank charges monthly fees or fees for withdrawals, as these can eat into your interest earnings.

Frequently Asked Questions

Can a bank lower my interest rate without warning?

No. Banks must notify you before lowering your rate, usually by email or mail, and the change takes effect after a waiting period of at least 30 days. You can move your money to a different bank if you do not like the new rate. The bank cannot lower your rate retroactively on money you already have in the account.

Is the interest I earn on a savings account taxable?

Yes. Interest earned on a savings account is taxable income. If you earn $10 or more in a calendar year, the bank sends you a Form 1099-INT and reports the amount to the IRS. You must report this interest on your tax return. The tax you owe depends on your overall income and tax bracket.

Why does my bank pay almost no interest?

Large national banks often pay very low rates because they have many customers who stay with them for convenience rather than interest. Online banks and credit unions typically pay much more. If your bank pays under 0.1% APY, moving your money to an online bank or credit union could earn you hundreds or thousands more per year on the same balance.

What is the difference between APY and interest rate?

APY (annual percentage yield) includes the effect of compounding, while a simple interest rate does not. APY is the number to use when comparing accounts because it shows what you actually earn in a year. Banks must display APY prominently, so always compare APY to APY, not APY to a simple rate.

Can I earn more interest by moving my money between banks?

Yes, but there are limits. You can move money between banks as often as you want, but some banks have rules about how many withdrawals you can make per month from a savings account. Also, moving money takes time — typically one to three business days for a transfer. If rates are changing rapidly, the rate you see today may be different by the time your transfer completes.
