APY Calculator: How To Calculate Your Annual Percentage Yield

CEO, The Annuity Expert

Investors always want to know what they can earn from their investments. The higher the return, the better. But when comparing investment options, it’s essential to look at the Annual Percentage Yield (APY) rather than the interest rate. Why? Because the APY takes into account the effect of compounding, while the interest rate does not. Use our APY Calculator to calculate your Annual Percentage Yield. Then, with competitive interest rates, learn how to help your money grow faster.

What Is Annual Percentage Yield (APY)?

Annual Percentage Yield (APY) is the total interest you earn on investment over a year. This includes both the initial interest rate and any compounding interest. Compounding interest is when the interest earned on an investment is reinvested so that you earn interest on your original investment plus any previously earned interest.

For example, let’s say you have $100 that you invest at an interest rate of 12%. After one year, you would have earned $12 in interest. If the interest were compounded, you would then earn interest on the original $100 plus the $12 interest for $114.

This may not seem a big difference, but it can add up over time!

How Can APY Benefit You?

Understanding the APY is crucial if you’re looking to invest your money. This way, you can make informed decisions about where to put your money and how much interest you can earn. In addition, you will earn more interest on your investment over time with a higher APY.

For example, let’s say you have $1,000 that you want to invest. You have two options:

  • Option A) An investment with an APY of 12%
  • Option B) An investment with an APY of 24%

When choosing where to invest your money, it’s essential to compare APYs to make the best decision for your needs.

The Basics of Compounding

Compounding is the process of earning interest on interest. For example, if you invest $1,000 in an account with a 5% interest rate, you’ll earn $50 in interest after one year. However, if the interest is compounded monthly, you’ll earn an additional $2.44 over the year, bringing your total earnings to $52.44. The more frequently interest is compounded, the more quickly your investment will grow.

What Is Annual Percentage Yield?

The Annual Percentage Yield (APY) is the annual percentage rate on an account that pays compound interest, such as a savings account, fixed annuity, money market account, or Certificate of Deposit (CD).

What Is Compounding?

Compounding occurs when the annual interest is earned on the original investment and the accumulated interest from previous periods. The more often compounding occurs, the greater its annual percentage rate will be.

How To Calculate APY

To calculate your APY (Annual Percentage Yield), you need to know the interest rate and how often it is compounded within a year.

First, convert the interest rate to a decimal by dividing it by 100.

Next, add 1 to the interest rate.

Then, raise the result to the power of the number of times the interest is compounded in a year.

Finally, subtract one from the result and multiply by 100 to get the APY as a percentage.

To calculate APY, you’ll need to know three things:

  1. The interest rate
  2. The frequency of compounding
  3. The number of days in the year

Once you have this information, you can use this formula:

APY = ((1 + r/n)^nt – 1) x 100


r = interest rate

n = number of compounding periods per year

t = number of years invested

For example, let’s say you’re looking at a 3-year CD that pays 2% interest, compounded quarterly. This means that there are four compounding periods per year. You would plug those numbers into the formula like this:

APY = ((1 + 0.02/4)^(4*3) – 1) x 100 so APY = 2.08%

Let’s compare that to a 2-year CD that pays 1.5% interest, compounded monthly. There are 12 compounding periods per year for this investment. So you would use this formula: APY = ((1 + 0.015/12)^(12*2)-1) x 100 and find that APY= 1.53%. Even though the first CD has a higher interest rate, it earns less than the second CD because it compounds interest less frequently. That’s why it’s important to consider the interest rate and how often it compounds when choosing an investment.

The Benefits of APY

The savings calculator APY is a critical metric when evaluating investment options because it gives you a better idea of the overall returns you can expect over time. Here are some of the key benefits of using APY to evaluate investments:

Comparing Investment Options

An APY calculator makes comparing the returns on different investment options easy, even if they have different interest rates or compounding frequencies. For example, if you’re considering two savings accounts with different interest rates and compounding frequencies, you can use APY to determine which will give you the highest overall returns.

Maximizing Your Returns

Understanding how APY works allows you to make smarter investment decisions that maximize your returns over time. For example, you might invest in an account with a higher interest rate or more frequent compounding to earn more interest over time. Additionally, you might reinvest your interest earnings into the investment to take advantage of compounding. However, it is essential to remember that the IRS considers interest earnings, including those from the compounding, taxable income.

Is APY Monthly Or Yearly?

The APY is the annual interest yield credited to a checking, savings, or deposit account. It’s calculated as a percentage and shown as such. The APY, or Annual Percentage Yield, is the annual interest rate on deposit accounts held over a year, including compounding, and is the accumulation of a lump sum or monthly deposits.

Which Accounts Have An APY?

When it comes to interest rates, not all accounts are created equal.

  • The checking account generally has the lowest annual interest rate, followed by savings accounts.
  • Money markets offer slightly higher rates, while CD rates can vary depending on the term length, balance initial deposit, and current market conditions.
  • Finally, annuity rates generally offer the highest interest rates, making them a popular choice for retirement savings.

Of course, interest rates are just one factor when choosing a financial account. But if you’re looking to maximize your earnings, it’s essential to understand how different types of accounts compare in shopping an interest rate.

Next Steps

When deciding where to invest your money, look at the Annual Percentage Yield rather than the interest rate. This is because the APY considers the effect of compounding while the interest rate does not. This can significantly affect how much your investment will grow over time.
