The answer depends on the interest rate and how long the money sits there
A $1,000 deposit in a savings account earning 4.5% annual percentage yield (APY) will earn about $45 in one year, assuming you don't add or withdraw money. At 0.01% APY — what some traditional banks offer — the same $1,000 earns about 10 cents per year. The difference between these two scenarios is real money, and it comes down to which bank you choose and what type of account you open.
The actual amount you earn depends on three things: the APY the bank offers, how long your money stays in the account, and whether the interest compounds (meaning you earn interest on your interest). Most savings accounts compound interest daily or monthly, which means your balance grows a little faster than straightforward math suggests.
This matters because the interest rate landscape has shifted. Five years ago, most savings accounts paid nearly nothing. Today, some banks pay rates that are worth seeking out — but only if you know where to look and what the numbers actually mean for your money.
Key Takeaways
- A $1,000 deposit earning 4.5% APY generates roughly $45 per year, while the same amount at 0.01% APY earns about 10 cents.
- Interest rates vary widely between banks — traditional brick-and-mortar banks typically offer much lower rates than online banks.
- The frequency of compounding (daily, monthly, or quarterly) affects your total earnings, though the difference is usually small on $1,000.
- Your money must stay in the account for the full year to earn the full annual amount; withdrawing early may trigger fees or forfeit accrued interest.
- High-yield savings accounts at online banks currently offer the highest rates, but these rates change and are not may provide to stay the same.
How the math works with different interest rates
The simplest way to estimate earnings is to multiply your balance by the APY. A $1,000 balance at 4.5% APY earns $1,000 × 0.045 = $45 in one year. At 1% APY, you earn $10. At 0.01% APY, you earn $0.10.
This calculation assumes the interest compounds annually, which is the clearest way to think about it. In reality, most banks compound more frequently — daily or monthly — which means you earn a tiny bit more because interest gets added to your balance partway through the year, and then you earn interest on that interest.
For $1,000, the difference between annual and daily compounding is usually less than a dollar per year. On larger balances, the difference becomes more noticeable. The bank's disclosure documents will show you the APY, which already accounts for compounding, so you can use the straightforward multiplication method above without worrying about the math underneath.
Where to find the highest rates right now
Online banks currently offer the highest savings rates because they have lower overhead costs than physical branches. As of early 2024, some online banks offer rates between 4% and 5.35% APY on savings accounts with no minimum balance. These rates change frequently — sometimes weekly — so the exact number you see today may be different next month.
Traditional banks (the kind with a branch near you) typically offer rates between 0.01% and 0.5% APY. The convenience of walking into a branch comes with a cost: much lower interest earnings. If you have $1,000 at a traditional bank paying 0.1% APY, you earn $1 per year.
Credit unions fall somewhere in between. Some credit unions offer competitive rates similar to online banks, while others offer rates closer to traditional banks. Your earnings depend on which credit union you join and what account type you choose.
The catch with online banks is that you cannot deposit cash in person or speak to someone face-to-face. If you need those services, you will earn less interest, but you gain convenience and security. This is a real trade-off worth thinking through based on how you actually use your money.
What happens to your interest if rates change
Banks can change the interest rate they offer at any time, and they often do. If you open a savings account at 4.5% APY and the bank later drops the rate to 3%, your new deposits and any interest earned going forward will be at the lower rate. Money already in the account does not retroactively lose interest — you keep what you earned — but future earnings happen at the new rate.
This is why the "best" rate today may not be the best rate next month. Some people move their money between banks to chase higher rates. Others accept a slightly lower rate in exchange for stability or the convenience of keeping everything in one place. Both approaches are reasonable; it depends on how much time you want to spend managing your accounts.
How long your money needs to stay in the account
The APY assumes your money stays in the account for a full year. If you withdraw your $1,000 after six months, you earn roughly half the annual interest — about $22.50 at 4.5% APY. The exact amount depends on how the bank calculates interest for partial years, which varies.
Some savings accounts charge a withdrawal fee or penalty if you take money out within a certain period, though this is less common now than it used to be. Before opening an account, check whether there are any restrictions on how often you can withdraw or whether early withdrawals cost you money. Most regular savings accounts have no withdrawal limits, but some specialty accounts (like money market accounts) may have restrictions.
Comparing accounts side by side
| Account Type | Typical APY Range | Interest on $1,000 per Year | Where to Find It |
|---|---|---|---|
| Online savings account | 4.0% to 5.35% | $40 to $53.50 | Online banks (Marcus, Ally, Wealthfront, others) |
| Traditional bank savings | 0.01% to 0.5% | $0.10 to $5 | Local or national banks with branches |
| Credit union savings | 0.5% to 4.5% | $5 to $45 | Credit unions (varies by institution) |
| Money market account | 4.0% to 5.0% | $40 to $50 | Online banks and some traditional banks |
The rates shown above reflect what was available in early 2024, but they change regularly. Use this table to understand the range, not as a may provide of what you will find. When you are ready to open an account, check the current rates directly on the bank's website.
Why the rate matters more than you might think
On $1,000, the difference between 0.01% and 4.5% is $44.90 per year. That is not life-changing money. But the same principle applies to larger balances: on $10,000, that difference becomes $449 per year. On $50,000, it becomes $2,245 per year. If you have money sitting in savings, moving it to a higher-rate account costs nothing and takes about 15 minutes.
The other reason the rate matters is that it reflects what the bank thinks your money is worth. A bank offering 4.5% believes it can lend that money out or invest it in a way that makes it worthwhile to pay you that much. A bank offering 0.01% is essentially saying your money is not worth much to them — they are betting you will not bother to move it. Choosing a higher rate is a small way of voting with your money.
Frequently Asked Questions
Do I have to pay taxes on the interest I earn?
Yes. Interest earned in a savings account is taxable income. The bank will 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. On $1,000 earning $45, you would owe taxes on that $45 at your regular income tax rate.
What if I add more money to the account during the year?
Each deposit earns interest from the day it is deposited. If you deposit $1,000 on January 1 and another $500 on July 1, the first $1,000 earns interest for the full year, and the second $500 earns interest for six months. The bank calculates this automatically.
Is my $1,000 safe in a savings account?
Yes, if the bank is insured by the FDIC (Federal Deposit Insurance Corporation). FDIC insurance protects up to $250,000 per depositor per bank, so your $1,000 is fully protected even if the bank fails. Check the bank's website to confirm FDIC coverage before opening an account.
Can the bank lower my interest rate without warning?
Yes. Banks can change rates at any time without notice. However, they typically announce rate changes on their website and may send you a notice. If a rate drop bothers you, you can move your money to a different bank — there is no penalty for switching.
Why do online banks pay more interest than traditional banks?
Online banks have lower costs because they do not maintain physical branches or employ as many staff. They pass some of those savings to customers in the form of higher interest rates. Traditional banks use their branch network as a selling point, which costs money, so they offer lower rates to offset that expense.
