A high-interest savings account is worth opening if you keep money you might need within the next few years and want it to earn more than a regular savings account offers
High-interest savings accounts (often called HISAs) pay a higher annual percentage yield (APY) than traditional savings accounts at brick-and-mortar banks. The difference matters: a regular bank savings account might pay 0.01% APY, while a high-interest account at an online bank might pay 4.5% to 5.3% APY. On $10,000, that gap means earning roughly $450 per year instead of $1.
The catch is that high-interest accounts come with trade-offs. You cannot withdraw money instantly like you can from a checking account—most take one to three business days to move funds out. You also need to keep a minimum balance, which varies by bank but often starts at $0 to $25,000. And the APY itself changes: when the Federal Reserve raises or lowers interest rates, banks adjust what they pay you.
Whether you should open one depends on three things: whether you have money sitting around that you do not need right now, whether you can leave it untouched for at least a few months, and whether the higher rate is worth the slower access.
Key Takeaways
- High-interest savings accounts pay 4% to 5%+ APY compared to 0.01% to 0.05% at traditional banks, which adds up quickly on larger balances.
- Your money takes one to three business days to withdraw, so these accounts work for money you need in months or years, not days.
- The APY changes when the Federal Reserve adjusts interest rates, so the rate you see today may be lower in six months.
- Online banks offer the highest rates because they have lower overhead costs than physical bank branches.
- You should keep your emergency fund (three to six months of expenses) in a high-interest account rather than a checking account, since you rarely need it immediately.
Who should open a high-interest savings account
Open one if you have money that sits in a regular savings account or checking account earning almost nothing. This includes emergency funds, money you are saving for a down payment on a house or car in one to three years, or cash you set aside for a known expense like a vacation or home repair.
Do not open one if you need the money within the next week or two, or if you are the type to dip into savings frequently. The three-day withdrawal window makes it unsuitable for true emergency money you might need overnight (keep a small amount in checking for that). It also does not make sense if you have less than $1,000 to deposit—the interest earned will be small enough that the effort of managing another account is not worth it.
High-interest accounts also work well if you are saving toward a specific goal and want the interest to help you reach it faster. On $25,000 saved for a house down payment, earning 5% instead of 0.01% means an extra $1,250 per year in your account without you doing anything.
How much more money you actually earn
The difference between a high-interest account and a regular savings account compounds over time, but the absolute amount depends on your balance. Here is what you earn per year on different amounts at current typical rates:
| Balance | At 0.01% APY (regular bank) | At 5% APY (high-interest account) | Difference per year |
|---|---|---|---|
| $1,000 | $0.10 | $50 | $49.90 |
| $5,000 | $0.50 | $250 | $249.50 |
| $10,000 | $1.00 | $500 | $499.00 |
| $25,000 | $2.50 | $1,250 | $1,247.50 |
These numbers assume the APY stays constant, which it will not. When the Federal Reserve raises rates, banks raise what they pay you. When the Fed cuts rates, banks cut their rates too—sometimes within days. The rates shown here are current as of early 2024, but they may be lower by the time you read this.
The interest is taxed as ordinary income, so you will owe federal income tax on whatever you earn. If you earn $500 in interest and you are in the 22% tax bracket, you owe roughly $110 in taxes on that interest. The bank will send you a 1099-INT form at tax time showing how much you earned.
The difference between high-interest accounts and money market accounts
A money market account is similar to a high-interest savings account but usually requires a higher minimum balance (often $2,500 to $10,000) and may come with a debit card or checkbook. The APY is usually comparable to a high-interest savings account. The main advantage is convenience if you want to write checks or use a debit card; the main disadvantage is the higher minimum balance requirement.
A certificate of deposit (CD) is different: you lock your money away for a set period (three months to five years) in exchange for a may provide, usually higher APY. You cannot touch the money without paying a penalty. CDs make sense if you know you will not need the money for a specific time period and want a may provide rate. High-interest savings accounts are more flexible because you can withdraw whenever you want (though it takes a few days).
For most people, a high-interest savings account is the better choice because it gives you the higher rate without locking your money away.
How to open one and what to watch for
Most high-interest savings accounts are offered by online banks like Marcus, Ally, American Express Personal Savings, Wealthfront, and others. You open one entirely online—no branch visit needed. The process takes 10 to 15 minutes and requires your Social Security number, address, and a way to fund the account (usually a transfer from another bank).
When comparing accounts, look at three things: the current APY (not the promotional rate, which expires), the minimum balance requirement, and how long withdrawals take. Most online banks take one to three business days to transfer money out. Some offer faster transfers if you pay a small fee or meet a higher balance threshold.
Check whether the account is FDIC insured. This means if the bank fails, the federal government guarantees your deposits up to $250,000. All legitimate online banks carry this insurance, but it is worth confirming before you move money.
Avoid accounts with monthly fees, account maintenance charges, or penalties for low balances. Most high-interest accounts have none of these, so if one does, choose a different bank.
When interest rates drop and your APY falls
The APY on a high-interest savings account is not fixed—it changes when the Federal Reserve adjusts its benchmark interest rate. When rates fall, banks lower what they pay you, sometimes within days. When rates rise, banks raise what they pay you, but usually more slowly.
This means the 5% rate you see today might be 3.5% in six months if the Fed cuts rates. You cannot lock in a rate with a savings account the way you can with a CD. If you want a may provide rate that does not change, a CD is the right tool.
That said, even when rates fall, a high-interest savings account will still pay more than a traditional bank account. And if rates rise again, your rate rises with it. The account remains a good place to keep money you might need in the next few years.
Frequently Asked Questions
Can I withdraw money from a high-interest savings account anytime?
Yes, but it takes one to three business days for the money to reach your checking account. You cannot get cash instantly like you can from an ATM. If you need money within hours, keep a smaller emergency fund in your checking account and the rest in the high-interest account.
Do I have to pay taxes on the interest I earn?
Yes. Interest earned in a savings account is taxed as ordinary income at your federal tax rate. The bank sends you a 1099-INT form at tax time showing how much you earned. If you earn $500 in interest and are in the 22% tax bracket, you owe roughly $110 in taxes on that interest.
What happens if the bank fails?
Your money is protected up to $250,000 by FDIC insurance, which is backed by the federal government. This means even if the bank goes under, you get your money back. All legitimate online banks carry this insurance.
Is a high-interest savings account better than investing the money in stocks?
No, but they serve different purposes. Stocks have higher long-term returns but also higher risk and volatility. A high-interest savings account is for money you might need in the next few years and cannot afford to lose. Stocks are for money you can leave alone for five years or more.
Can I have multiple high-interest savings accounts?
Yes. Some people open separate accounts to organize money by goal—one for an emergency fund, one for a house down payment, one for a vacation. Just remember that FDIC insurance covers up to $250,000 per bank, not per account, so if you have $300,000 across two accounts at the same bank, only $250,000 is insured.
