The answer depends on your bank's APY and how long you leave the money untouched
A $5,000 deposit earning interest is not a fixed number — it changes based on three things: the annual percentage yield (APY) your bank offers, how often interest compounds (usually daily or monthly), and how long the money sits in the account. A bank offering 4.5% APY will pay you roughly $225 per year on $5,000. A bank offering 0.01% APY will pay you about 50 cents per year on the same amount. The difference between a high-yield savings account and a traditional savings account can be $200 or more annually on this balance.
The math is straightforward once you know the APY. Multiply your balance by the APY rate, then divide by 12 to see what you earn per month. On $5,000 at 4.5% APY, that is ($5,000 × 0.045) ÷ 12 = $18.75 per month. If interest compounds daily — which most online banks do — you earn slightly more because each day's interest earns interest the next day, but the difference on $5,000 is usually a few dollars per year.
Key Takeaways
- At 4.5% APY, $5,000 earns roughly $225 per year; at 0.01% APY, it earns about 50 cents.
- Online banks and credit unions typically offer higher APY than brick-and-mortar banks, sometimes 10 to 40 times higher.
- Interest compounds daily at most online banks, meaning you earn a small amount of interest on your interest.
- Your earnings are taxed as ordinary income, so you will owe federal and possibly state income tax on the interest you earn.
- Moving $5,000 from a 0.01% account to a 4.5% account costs nothing and takes a few days, but the annual difference in earnings is real money.
Where to find current APY rates for different account types
Banks change their APY rates frequently — sometimes weekly — so there is no single "correct" answer that stays true for months. The easiest way to see what is available right now is to visit the websites of banks you are considering and look for the savings account rate displayed on their homepage or savings product page. Most online banks show the APY prominently because it is their main selling point.
You can also use rate-comparison sites like Bankrate, DepositAccounts, or the FDIC's BankFind tool to see what multiple banks are offering. These sites update regularly and let you filter by account type (savings, money market, certificates of deposit) and by whether you want a local bank or an online bank. Keep in mind that rates shown today may be different by the time you open an account — banks raise and lower rates based on what the Federal Reserve does.
How compounding affects your $5,000 over time
Compounding means you earn interest on your interest. If your bank compounds daily, each day's earnings get added to your balance, and the next day you earn interest on that slightly larger balance. Over a year, this compounds to a meaningful difference — though on $5,000 it is usually $5 to $15 more than straightforward interest would give you.
Here is what $5,000 looks like over five years at different rates, assuming daily compounding and no additional deposits:
| APY Rate | After 1 Year | After 3 Years | After 5 Years |
|---|---|---|---|
| 0.01% | $5,000.50 | $5,001.50 | $5,002.50 |
| 1.5% | $5,075.68 | $5,229.92 | $5,388.90 |
| 4.5% | $5,230.68 | $5,714.91 | $6,234.05 |
| 5.0% | $5,256.33 | $5,796.37 | $6,381.41 |
The difference between 4.5% and 5.0% looks small in year one ($26), but by year five it is $147. This is why shopping for the highest available rate matters, especially if you are saving for something years away.
Why online banks pay more interest than traditional banks
Online banks have lower overhead costs than banks with physical branches. They do not pay for building leases, tellers, or branch managers. Because their costs are lower, they can afford to pay you more of the interest they earn from lending out deposits. A traditional bank with a branch on your street might offer 0.01% APY on savings. An online bank with no branches might offer 4.5% on the same type of account.
Both are insured by the Federal Deposit Insurance Corporation (FDIC) up to $250,000 per account, so the safety is identical. The only trade-off is that you cannot walk into an online bank to deposit cash or speak to someone in person — you do everything by phone, email, or their website. For most people saving money, this trade-off is worth it.
What happens to your interest earnings at tax time
Interest you earn on a savings account is taxed as ordinary income. If you earn $225 in interest on your $5,000, you will owe federal income tax on that $225, and possibly state income tax depending on where you live. Your bank will send you a Form 1099-INT in January showing how much interest you earned during the previous year, and you report that amount on your tax return.
This means your real earnings are less than the APY suggests. If you are in the 22% federal tax bracket and earn $225 in interest, you will owe about $50 in federal tax, leaving you with $175 in actual after-tax earnings. This is still better than earning 50 cents at a low-rate bank, but it is worth understanding that the interest is not entirely yours to keep.
Moving money to a higher-rate account without losing interest
If your $5,000 is currently in a low-rate savings account and you want to move it to a higher-rate account, you can do so without penalty or loss of interest. Interest accrues daily, so you earn interest right up until the moment you transfer the money out. Once the transfer completes — usually within two to three business days — your new bank starts earning interest at its rate.
The process is straightforward: open a new account at the higher-rate bank, then request a transfer from your old bank. You provide the new bank with your old account number and routing number, and they handle the rest. You do not need to withdraw cash or write a check. Some banks even offer a small bonus (usually $25 to $200) for opening a new account and transferring in a minimum balance, though these bonuses come with conditions like keeping the account open for a certain number of months.
Frequently Asked Questions
Will my $5,000 earn the same amount every month?
No. Because interest compounds daily, you earn slightly more each month as your balance grows. In month one you might earn $18.75, but in month 12 you will earn slightly more because your balance is now $5,225 instead of $5,000. The difference is small on $5,000, but it adds up over years.
What if I withdraw some of the money before the year ends?
You still earn interest on the money that remains. If you withdraw $1,000 after six months, you earned interest on $5,000 for six months, then interest on $4,000 for the remaining six months. There is no penalty for withdrawals from a savings account, though some banks limit how many withdrawals you can make per month.
Is the APY I see online may provide to stay the same?
No. Banks change APY rates frequently, sometimes weekly. The rate you see today may be different when you open an account, and it will almost certainly be different in six months. You are not locked into a rate unless you open a certificate of deposit (CD), which fixes your rate for a set period like one year or five years.
Can I earn more interest by splitting $5,000 across multiple banks?
No. The interest rate is the same whether you have $5,000 in one account or $2,500 in two accounts at the same bank. However, splitting across different banks can make sense for FDIC insurance purposes — each bank insures up to $250,000 per account holder, so if you have more than $250,000 to save, using multiple banks protects all of it.
What is the difference between APY and interest rate?
APY (annual percentage yield) includes the effect of compounding, while a straightforward interest rate does not. If a bank advertises 4.5% APY, that is the actual amount you will earn in a year accounting for daily compounding. A straightforward 4.5% interest rate would earn you slightly less because it does not account for compounding.
