What Is APY? A Simple Guide to Annual Percentage Yield

Whether you’re saving for a rainy day or building up your savings for a big purchase, you’ve probably come across the term APY. But what exactly does it mean and why should you care?

Let’s break it down in simple terms so you can make smarter money moves.

What Does APY Stand For?

APY stands for Annual Percentage Yield. It describes how much interest you’ll earn on your money over one year, including compound interest.

That last part, compound interest, is key. Compounding means you’re not just earning interest on your initial deposit, but you’re also earning interest on the interest you’ve already earned. It’s how your money grows faster over time.

APY vs. Interest Rate: What’s the Difference?

At first glance, APY and interest rate might look the same. But there’s one key difference:

• Interest rate is the base rate of interest your account earns
• APY is the total interest you earn on money in an account over one year, which includes compound interest

How Is APY Calculated?

APY is calculated using this formula:

APY = (1 + r/n)^n - 1

• r is the annual interest rate
• n is the number of compounding periods per year (e.g., 12 for monthly)

While you don’t need to memorize the math, what matters is this: the more frequently your interest compounds, the higher your APY will be.

Why APY Matters

Here’s why APY is worth paying attention to, especially if you’re saving for a big purchase:

1. It helps you compare savings options.

When you're shopping around for savings accounts, CDs, or high-yield savings accounts, comparing APYs gives you a clear picture of which option will help your money grow faster.

2. It reflects your true earnings.

Unlike a simple interest rate, APY tells the full story. It factors in how often your interest compounds, so you can see what you’re earning over a year.

3. It keeps your money working for you.

The higher the APY, the more interest you’ll earn, especially if you leave your money untouched. Over time, even small differences in APY can lead to bigger gains.

Where You’ll See APY

You’ll typically see APY mentioned in:

• Savings accounts

• Money market accounts
• Certificates of deposit (CDs)
