Summary

• A high-yield savings account is a type of savings account that pays a higher interest rate than many regular savings accounts.

• You earn money through interest, which is the cost a bank pays you for keeping your money there.

• Annual percentage yield, or APY, shows you how much your money might grow over a year with interest and compounding included.

• Many high-yield savings accounts (HYSA) exist at online banks, which often pay more because they have lower internal costs.

• You usually can move your money in and out, but there may be limits on certain types of withdrawals.

• Accounts at banks insured by the Federal Deposit Insurance Corporation or at credit unions insured by the National Credit Union Administration have federal protection up to certain amounts.

• High-yield savings accounts are one tool you can use to store cash and grow it at the same time, while still having easy access for withdrawals and deposits.

If you want your savings to grow, you might look at a high-yield savings account. A high-yield savings account is a savings account that pays a higher interest rate than many standard savings accounts at large brick and mortar banks. You still log in, see a balance, and move money in and out. The main difference is how much interest your money earns over time.

What is interest and APY?

When you put money into a savings account, the bank, credit union, or financial institution pays you interest. Interest is the amount of money a financial institution pays you for holding your deposits with them. You can think of it as a small reward for letting them keep your money.

You’ll often see two terms when you look at a high-yield savings account:

• Interest rate is the simple yearly rate the institution uses to calculate how much interest you earn before compounding.

• Annual percentage yield, or APY, is the total percentage amount your money might grow in one year when the bank applies both the interest rate and the effect of compounding, which means earning interest on interest.

APY is a standardized way to show the total yearly impact of interest and compounding so you can compare accounts more easily across different banks and different compounding schedules. The United States Truth in Savings Act sets rules for how banks must display APY so that people can compare accounts more clearly. 

Even if the formula looks technical, the key idea is simple. When two accounts show APY, you can compare the two APY numbers directly to see which one may grow your money faster, assuming other features are the same. 

How does compounding work?

Compounding is what happens when you earn interest, on your interest. 

Here is how compounding works. The bank pays interest only on the money you deposit, which is called your principal. After that, the bank keeps adding the interest you’ve earned to your balance, and then it starts paying interest on this larger balance.

Many banks compound interest daily, monthly, or yearly. With daily compounding, the bank calculates interest each day on your current balance and adds it according to its schedule. With yearly compounding, the bank does that calculation only once per year. When compounding happens more often, your money may grow a bit faster, even if the stated interest rate looks the same.

For example, when a bank compounds interest more often, your ending balance grows slightly more compared to the same interest rate with less frequent compounding.

You don’t have to run the math yourself unless you want to. The main point is that APY already includes the impact of compounding. When you see APY, you’re seeing the effect of both the interest rate and how often it compounds.

Why many high-yield savings accounts are online

Many high-yield savings accounts are available through online or mobile banking or app-based financial platforms that partner with banks (also known as neobanks). These institutions often have lower overhead costs than large branch-based banks, which may help them offer higher rates.

Many large brick and mortar banks pay very low interest on standard savings accounts, sometimes close to zero, while some high-yield savings accounts pay much higher APYs. 

For example, some traditional banks pay around 0.01 percent on savings, while some high-yield savings accounts can pay rates that are much higher, depending on market conditions at the time.

These comparisons change over time as interest rates in the wider economy change, so it can help to check current information from reliable sources and from the institution itself.

How interest rates on high-yield savings accounts can change

Many high-yield savings accounts have variable interest rates. A variable rate is a rate that can go up or down over time. Banks often adjust these rates based on broader interest rate conditions, such as changes in the target interest rate that the United States Federal Reserve sets for banks that lend to each other overnight. When that broader rate rises or falls, many banks adjust what they pay on savings.

When general interest rates rise, some online banks and credit unions may raise the rates on their high-yield savings accounts, and when general interest rates fall, those same banks may lower them.

Because of this, a high-yield savings account might have a higher APY at some points and a lower one at others. So keep in mind, the rate you see today might not be permanent. Many banks list a current APY and also explain that it can change at any time. Educational content from banks and consumer finance sites often reminds readers to check the most recent rate on the bank’s site. 

Safety: FDIC and NCUA insurance

Many high-yield savings accounts at banks in the United States carry federal insurance through the Federal Deposit Insurance Corporation, or FDIC. FDIC insurance is a federal program that protects deposits up to certain limits if an FDIC-insured bank fails.

According to the FDIC’s own educational brochure “Deposits at a Glance,” FDIC insurance covers up to $250,000 per depositor, per insured bank, per ownership category, such as single accounts or joint accounts. The brochure also explains that this coverage includes both your principal and any interest that has been credited to your account, up to the insurance limit.

Credit unions in the United States that are federally insured use a similar system through the National Credit Union Administration, or NCUA (National Credit Union Administration). NCUA insurance also protects up to $250,000 per member, per insured credit union, per ownership category. FDIC and NCUA coverage are both backed by the federal government and work in similar ways. The main difference is that FDIC applies to banks and NCUA applies to credit unions.

If you’re comparing high-yield savings accounts, it can help to check whether the bank is FDIC-insured or the credit union is NCUA-insured and to read how the coverage applies to your type of account. 

Liquidity and access to your money

Liquidity describes how quickly and easily you can turn an asset into cash that you can use. A high-yield savings account is a liquid account, because you can usually transfer money to a checking account or another account fairly quickly through your app or online banking.

At the same time, many banks put some limits around how you move money out, such as caps on the number of certain types of withdrawals per month or minimum transfer amounts for some types of transfers. Some high-yield savings accounts don’t provide a debit card or checkbook. They may focus on electronic transfers in and out. Those details live in the bank’s account agreement and disclosures.

While savings accounts are liquid, they’re designed for saving, not for day-to-day spending. A high-yield savings account can work well for savings goals, while checking accounts focus more on frequent payments and everyday spending.

How high-yield savings compares to other common cash accounts

Many people compare high-yield savings accounts to a few other types of accounts: traditional savings, money market accounts, and certificates of deposit.

Traditional savings accounts

A traditional savings account at a large brick and mortar bank might look very similar to a high-yield savings account in terms of how you use it. The big difference often shows up in the interest rate. A low traditional savings rate can lead to less earned interest over a year compared to a higher high-yield savings rate.

Money market accounts

A money market account is a type of deposit account that can combine features of savings and checking. It may allow limited check-writing or debit card use while still earning interest. Both money market accounts and high-yield savings accounts are often insured by the FDIC or NCUA, but money market accounts sometimes require higher minimum balances and may offer different rates.

Certificate of deposit

A certificate of deposit, often shortened to CD, is a deposit where you agree to leave your money in the account for a set term, such as six months or two years, in exchange for a fixed interest rate. CDs can sometimes pay rates that are similar to or higher than high-yield savings accounts, but you may lose some flexibility because you usually pay a penalty if you withdraw before the term ends.

Each of these tools financial products work differently. A high-yield savings account lies somewhere in the middle. It often pays more than a traditional savings account, keeps liquidity higher than a CD, and may have easier access than some money market accounts.

Taxes on interest from high-yield savings

Interest you earn from a high-yield savings account usually counts as taxable income. In the United States, this interest generally appears as interest income on your federal tax return.

Banks, neobanks, and other financial institutions typically send a form called Form 1099-INT when you earn at least 10 dollars in interest in a single year, though you’re still supposed to report all interest income even if it’s less than that. Interest is usually taxed at your ordinary income tax rate for the year, which depends on your income level and filing status.

What to consider when comparing high-yield savings accounts

When you explore high-yield savings accounts on your own, you might focus on how they work in a few key areas:

• The stated APY, and whether it’s a standard rate or a temporary promotional rate.

• How often the account compounds interest, which the APY already reflects.

• Whether the bank or credit union is covered by FDIC or NCUA insurance and how that coverage applies.

• Any balance requirements, such as minimum opening deposit or minimum balance to earn the advertised APY.

• Any fees listed in the account’s fee schedule, such as monthly fees or transfer fees.

• Any limits on transfers and withdrawals.

As you look through a bank’s website or app, you’ll usually find these details in the rate sheets, account disclosures, and terms and conditions.

How high-yield savings accounts may support your financial progress

A high-yield savings account is one of several tools that can help you store money and see it grow over time. Because it usually combines interest earning with relatively easy access, some people find it useful for short-term and medium-term goals such as building an emergency cushion or saving towards big purchases.
