What is APY, and how does it affect my money goals?

Financial well-being is a learning journey filled with acronyms and jargon that can overwhelm you. One such term is APY, which is short for Annual Percentage Yield. If you need to know what an APY is, stick around and find out why this number matters and how it can affect your money goals.

What is APY?

Simply put, APY is the amount of interest you earn on money in a particular place over one year. The percentage represents how much your money will grow in a year through compound interest.

Compound interest definition

Compound interest is the combination of interest earned on a principal amount plus any additional interest accumulated in the process. In other words, it’s interest earned on interest. 

You have a new total amount when you add the accrued interest you’ve earned to the amount you started with (the principal balance). This new total then earns additional interest, leading to exponential growth over time. The key here is that the interest compounds, meaning it builds upon itself. For example, if you had $1 and earned a daily compounding interest of one cent today, you'll earn interest on $1.01 tomorrow.

How is APY calculated? 

In math terms, the equation for calculating APY is APY = (1+r/n)^n - 1. In this formula, 'r' represents the annual interest rate, and 'n' represents the number of compounding periods in a year. For example, if your savings account compounds monthly, 'n' would be equal to 12.

Basically, it means that the more frequently your account compounds, the higher your APY will be. This is why high-yield savings accounts often compound daily and have a higher APY than traditional savings accounts.

Here’s a more dramatic example: If you had a million dollars today and didn't pay any additional money into the account or withdraw from it in 10 years at an APY of 5%, you'd have:

Compounded daily: $1,648,664.81

Compounded monthly: $1,647,009.50

Compounded quarterly: $1,643,619.46

Compounded annually: $1,628,894.63

How is APY different from APR?

APY and APR (Annual Percentage Rate) are often used interchangeably, but they are not the same thing. APR is the annual interest rate that you pay on a loan or credit card. APY is the annual interest rate that you earn on a deposit or investment. The key difference between the two is that APY takes into account compound interest, while APR does not.

How to make the most of your APY

Here are a few tips to help you make the most of your APY and reach your money goals:

• Shop around for accounts with competitive APYs. Keep in mind that online banks often offer higher APYs than traditional brick-and-mortar banks.

• Consider opening a high-yield savings account, which typically offers a higher APY than a regular savings account.

• Take advantage of compound interest by leaving your money in the account for as long as possible, allowing it to grow over time.

• Compare APYs when choosing between different investment options to make the most informed decision.
