APY vs Interest Rate

When comparing different interest-bearing accounts, you may come across the terms APY (annual percentage yield) and interest rate. While similar, they are not the same thing.

The interest rate is the base rate the financial institution offers, while APY factors in how often that interest is compounded (or credited to the account). The more frequently interest is compounded, the faster your money grows, since interest is earned on previously earned interest more often. As a result, APY gives you a more accurate picture of potential earnings over time.

APY and Interest Rate Defined

Both APY and interest rate indicate how much you’ll earn on your balance in a savings account, or other interest-bearing account, but there is a key distinction between the two.

What Is APY?

If you deposit money into any type of savings account, you will earn an annual percentage yield (APY) on that money. The APY is a useful number because it tells you how much you’ll earn on your deposits over the course of a year, expressed as a percentage. The APY calculation takes into account the interest rate being offered, then factors in whether or not the financial institution offers compounded interest.

Compound interest is the interest you earn on the interest you’ve already earned. Depending on the bank or credit union, interest may compound daily, monthly, quarterly, or annually. The more frequently interest compounds, the faster your money grows.

What Is an Interest Rate?

When it comes to a savings account, an interest rate is simply the percentage return you’ll earn on your original balance, without compounding. The higher the interest rate, the more you’ll earn on your deposits. But interest rate is only one component of the account’s APY, which also factors in compound frequency — or how often interest is paid.

When it comes to loans (e.g., a mortgage, car loan, or credit card), the interest rate refers to the price you pay for using that money. The higher the interest rate, the more you’ll pay back in addition to the principal amount. The interest rate on a loan doesn’t include any fees associated with the loan, such as origination fees, application fees, or other charges. To understand the total cost of a loan, you’ll want to look at its APR (annual percentage rate).

APY vs. Interest Rate Explained

Why does interest rate vs. APY matter? When you are opening a bank account, it can make a difference as one can give you a better picture of how your money will grow while on deposit.

The interest rate tells you the basic rate at which your money will accrue interest. The APY, however, gives you better insight to how much interest you will earn by the end of a year because it factors in the boost that compound interest can deliver.

The APY Formula

For those who want to delve in a bit deeper, the actual formula for APY calculation is as follows: (1 + r/n)ⁿ – 1.

•   The “r” stands for the interest rate being paid.

•   The “n” represents the number of compounding periods within a year.

If, for example, the interest rate is 3.50%, then that’s what you’d use for the “r.” If interest is compounded quarterly, then “n” would equal four.

The “n,” or compounding frequency, can cause two different savings accounts with the same interest rates to have different APYs. For example, if two different banks offer a savings account with the same interest rate but one compounds quarterly and the other compounds annually, that the account that compounds annually would have a lower APY than the account that compounds quarterly or daily.

Fortunately, if you want to compare savings rates from one bank or credit union to another, you don’t need to perform any in-depth calculations.

Financial institutions are required to provide information on APY as part of the Truth in Savings Act. And, here’s the heart of it all: The higher the APY, then the more quickly the money you deposit can grow.

Calculating APR

The APR vs. interest rate of a loan tells you how much the loan will cost you over one year, including both the loan’s interest rate and fees, and is expressed as a percentage. A loan’s APR gives you a better sense of the true cost of the loan than the loan’s interest rate, since it includes fees. The higher the APR, the more you’ll pay over the life of the loan.

Thanks to the federal Truth in Lending Act, lenders must provide the APR of a loan. This allows you to compare loans apples to apples. A loan with a low interest rate but high fees may not be a good deal. In fact, you may be better off with a loan that charges a higher interest rate but no or lower fees. APR allows you to be a savvy consumer.

APR can be calculated with this formula:

APR = (((Interest + Fees ÷ Loan amount) ÷ Number of days in loan term) x 365) x 100.

Lenders will tell you the APR of a loan and you won’t need to perform any complicated calculations.

How Simple and Compound Interest Differ

With simple interest, no compounding is involved. If you were to deposit $10,000 in an account earning 4.00% simple interest, at the end of three years, your money would earn $1,200 for a total of $11,200.

If, however, the interest were compounded daily, you would earn around $408 the first year. The second year, interest would accrue on the principal and the interest earned in the first year, and you would earn roughly $425 the next year and then $442 the year after that, for a total of around $11,275.

While the difference in dollar amount may not seem earth-shattering in this example of a few years, when you are talking about your decades-long financial life, it can really add up. Your money will grow faster with compound interest, helping you reach your financial goals.

Types of High-Interest Accounts for Savings

If you’re looking to earn a competitive rate on your savings, you’ll want to compare accounts by looking at APYs, as well as account fees and balance minimums. Generally, you can find competitive rates by looking at high-yield savings accounts, money market accounts, and CDs.

•   High-yield savings accounts, typically offered by credit unions and online banks, are accounts that typically pay a substantially higher APY than the national average of traditional savings accounts. They generally also have low or no fees.

•   Money market accounts are savings accounts that offer some of the features of a checking account, such as checks or a debit card. They often come with a higher APY than a traditional savings account, but typically require a higher balance, such as $2,500 or more.

•   Certificates of deposits (CDs) also tend to pay a higher APY than a regular savings account but require you to leave your money untouched for a certain period of time, called a term. If you take money out before then, you’ll likely pay an early withdrawal penalty. CD terms typically range from three months to five years. Generally, the longer the term, the higher the APY (however, this isn’t always the case).

High-Interest Checking Accounts

Checking accounts work well for everyday spending but typically offer no interest or very little. A high-yield checking account is a special type of account offered by some financial institutions (such as traditional and online banks, and credit unions) that offers a higher-than-average APY. These are accounts designed to give you the flexibility of a traditional checking account (with checks and/or a debit card) but with higher-interest returns.

A few points to note:

•   Some high-interest checking accounts will offer different APY tiers, with higher account balances earning a higher APY than lower account balances.

•   Often, to qualify for the highest rate the checking account has to offer, you need to meet certain criteria. This might be making a certain number of debit card transactions in a month, having at least one direct deposit or automated clearing house (ACH) payment each month, or choosing to receive paperless statements.

The Takeaway

When it comes to choosing a savings account, it’s essential to understand the difference between APY (annual percentage yield) and interest rate. While both relate to how your money grows, they aren’t the same.

The interest rate is the basic rate the bank pays you for keeping your money in the account and doesn’t account for compounding, while APY includes the effects of compounding.

When comparing accounts, it’s a good idea to look at the APY, since it shows the real return on your money and can help you select an account that maximizes your earnings.
