Savings account rates can feel like a roller-coaster: They rise and fall as economic conditions change. Even so, today's top high-yield savings accounts offer rates well above the national average. By parking your cash in a high-yield savings account, you make your money work smarter, not harder, with the potential to earn hundreds (or even thousands of dollars) in interest over the next year. This is all without taking on the risks that come with investing.

If you have $30,000 sitting in a traditional savings account, the difference in earnings can be significant compared to a high-yield savings account. Here's how much interest you could potentially earn over the next year in a high-yield savings account, and what factors could affect your return.

What is a high-yield savings account?

A high-yield savings account (HYSA) is a deposit account that offers much higher interest rates than regular savings products. For example, regular savings accounts pay around 0.38% currently, while HYSAs can pay up to 4.15% in the current rate climate.

Rates on HYSAs aren't fixed and will fluctuate depending on the current rates set forward by the Federal Reserve. They also keep your money readily available, unlike products that aren't as liquid like CDs. HYSAs are more commonly offered by online banks and some credit unions, which pass along lower operating costs to their customers via their higher annual percentage yields (APYs).

Like traditional savings accounts, HYSAs are generally insured through the FDIC or NCUA up to the applicable limits, making them a low-risk place to store your cash. These accounts are useful for emergency funds, planned expenses, or money you're saving for short-term goals.

How much interest could $30,000 earn in one year?

How much you will earn on $30,000 in a HYSA depends on the APY your account pays.

At an APY of 4.00%, you will earn around $1,200 in interest over 12 months for a total of $31,200. This assumes daily compounding, that the rate remains unchanged, and you make no additional withdrawals or deposits.

Remember that the more money you keep in your account, the more interest you'll have the opportunity to earn.

Here are some examples of what your balance would be based on various rates:

APY Interest Earned Over 1 Year Ending Balance After 1 Year
4.25% $1,275 $31,275
4.15% $1,245 $31,245
4.00% $1,200 $31,200
3.80% $1,140 $31,140
3.50% $1,050 $31,050

See how much you could earn on your own balance with a top high-yield savings account.

Why do high-yield savings accounts pay more?

High-yield savings accounts often pay more because they are offered by online banks with lower operating costs than brick-and-mortar banks. Without lots of physical branches, these institutions can pass some savings on to customers through higher interest rates. HYSA rates are also influenced by Federal Reserve decisions, which can impact how much banks choose to pay on deposits.

How interest is calculated and compounded

Interest is typically calculated daily based on your balance, but credited to your account monthly. Many accounts compound interest daily, allowing you to earn interest on both your original deposit and previously earned interest. Since APY already accounts for compounding, it provides an easier way to compare savings account rates.

Could savings account rates change this year?

Interest rates are directly driven by economic conditions and decisions made by the Federal Reserve. If inflation continues to cool, the Fed may choose to lower interest rates. In this case, banks may also choose to reduce the APYs they offer on savings accounts.

But even if rates decline, HYSAs may continue to provide better returns than products like traditional savings accounts. Know that your bank isn't required to disclose to you if they drop your rate. Therefore, it's important to monitor rates frequently and compare accounts to find the most competitive options.

Who should consider a high-yield savings account?

Anyone who wants to save can consider a high-yield savings account. They are a great option for emergency funds, short-term savings goals, or money you want to keep accessible while also earning interest. Unlike investments, these accounts do not fluctuate with market changes. However, they aren't exactly designed for long-term wealth building, where investments may offer greater growth potential over a long period of time.

Bottom line

A high-yield savings account offers one of the easiest ways to earn more on money you aren't ready to tie up in investments. If you have $30,000 set aside, choosing a competitive high-yield savings account instead of a traditional savings account could mean earning around $1,200 in interest over the next year (though your actual return depends on rates changing).

One thing to also keep in mind is taxes. Uncle Sam imposes income taxes on interest earned in a savings account, as it is considered taxable income. You'll likely owe federal (and possibly state) income taxes on what you do earn. But, even after accounting for taxes, a high-yield savings account can still provide a meaningful boost to your emergency fund or other short-term savings goals while keeping your money safe and accessible.
