What Is a High-Yield Savings Account? (Simple Guide + USD Examples)

A high-yield savings account (HYSA) is a savings account that pays a significantly higher interest rate than a traditional bank savings account. While a normal savings account may offer 0.01%–0.30% APY, a high-yield savings account typically offers 3%–5% APY.

These accounts are usually offered by online banks, which can pay higher rates because they have lower operating costs.

How Does a High-Yield Savings Account Work?

Every HYSA pays interest using the APY (Annual Percentage Yield) system, which includes compounding. This means your money earns interest on interest.

For example:

If you deposit $10,000 at 4.50% APY:
After 1 year → $10,450
After 5 years → $12,469
(Assuming no additional contributions)

Most high-yield savings accounts compound interest either daily or monthly. The more frequent the compounding, the faster your balance grows.

HYSA vs. Traditional Savings Account

Here’s a simple comparison:

Feature Traditional Savings High-Yield Savings
Typical APY 0.01%–0.30% 3%–5%
Minimum balance Often required Usually low or none
Interest calculation Simple Compounded

Because of the higher interest rates, a HYSA is one of the simplest and safest ways to grow savings over time—especially for short-term and medium-term goals.

APY and Compounding Explained

APY includes compounding and therefore represents the “true” annual return.

APY formula:

APY = (1 + r/n)n – 1
