APY is an abbreviation for “annual percentage yield,” which is a number that indicates how much interest a bank account, such as a certificate of deposit, earns in one year. The higher the APY, the more you earn.

What does APY mean?

APY is a key feature to consider when shopping for a place to stash your savings. Some checking accounts pay interest, too.

An APY includes the effect of compounding interest, which is when both your principal and the accumulated interest earn interest. Compounding helps your cash grow faster than simple interest, which pays interest only on the principal.

Interest on an account can compound yearly, monthly, quarterly or daily. Accounts that compound more frequently generally earn more because the interest is computed and added to your account more often.

That’s why it’s important to consider APY – and not just the interest rate – when looking for a bank account. Comparing APYs helps you see how accounts stack up against each other.

What’s a typical APY?

Account APYs can differ dramatically, depending on the financial institution and the product. For example:

  • The checking accounts with the highest yields pay over 1 percent APY, while other checking accounts pay nominal to zero interest.
  • The national average for a savings account is only 0.1 percent APY, but the best savings accounts pay at least 1 percent APY.
  • The average APY on a one-year CD recently jumped 10 basis points to 0.52 percent, the biggest increase since October 2008. But if you shop around, you can find one-year CDs that pay 2 percent APY or higher.

Your product choice can make a difference in your earnings. Let’s say you put $5,000 into a one-year CD that pays the national average APY (0.52 percent). You will earn $26 in interest in that year. But if you put that money into a one-year CD that pays 2.5 percent APY, you will earn $100 in interest.

You can use Bankrate’s CD calculator to compare earnings.

How can you find the APY for an account?

Thanks to a federal law called the Truth in Savings Act (Federal Reserve Regulation DD), financial institutions must disclose to customers the account APY and the frequency of compounding, among other details.

This information usually can be found on bank websites.

If you want to figure out how much you might earn on an account given its APY, you can use Bankrate’s savings calculator. Say you want to put $1,000 into a savings account that earns 1.25 percent APY, and you plan to contribute $200 a month for two years. You’ll earn $82.77 in interest and have a balance of $5,882.77 at the end of two years.

APY vs. APR: The difference between the two

While APY represents how much interest you will earn on an account, APR, which stands for “annual percentage rate,” represents the annual cost to borrow money.

The APR is an important consideration when shopping for home loans, personal loans, car loans or credit cards.

For example, when you buy a house, the lender might offer an appealing mortgage rate, but it’s the APR that will tell you how much the loan will actually cost because rolled into that percentage are the interest, plus any points and fees the lender might charge.

So essentially, APY and APR are opposites because the APY indicates how much you will earn by saving money but the APR indicates how much you will pay to borrow money.

Is APY variable?

APYs can be fixed or variable, depending on the type of account you open. For example, a typical CD account pays a fixed rate for a specific term, such as one year or five years.

But savings and checking accounts pay variable APYs, which means the rate can fluctuate. The rate you get when you sign up might move up and down over time.

A key factor affecting APYs – and APRs – is what the Federal Reserve does with the federal funds rate. The Fed has been raising that rate fairly aggressively in 2022 in an effort to curb inflation.

While this is discouraging news for people trying to snag a low APR on a credit card or other loan, federal funds rate hikes are usually welcome news for savers because banks typically increase their APYs when the Fed raises the benchmark rate.

Bottom line

The APY on your bank or investment account tells you how much interest you will earn, factoring in the frequency of compounding. The power of compounding interest is that you’re not earning interest only on the cash you deposit; you earn interest on accumulated interest, which can grow your balance exponentially.

APY isn’t the only factor you should consider when shopping for a new account. Inquire about fees, such as monthly maintenance fees and administrative fees, because they can erode your earnings.

Be sure to know the APY and read the fine print on the account to understand the full cost of the product before signing up.
