It's important to know how much interest you'll pay or earn if the interest rate is compounded more frequently than yearly. Loans, lines of credit, and investments may all be affected by this.
By understanding how to calculate the annual percentage rate, you may accurately compare savings accounts, investment, and loans with varying compounding periods to see which one earns (or saves) the most money for you (APR).
The "Effective Annual Percentage Yield," or "EAPR," is a different moniker for this metric. In this case, we can see how AER can be used. A 12-month loan with a monthly APR of 12 percent is an example. On your first monthly report, you'll see a charge for interest of 14%.With some practise, you can calculate the annual percentage rate for a variety of financial instruments to see which one earns (or saves) the most interest over a variety of compounding periods (APR).
If you don't make any withdrawals and leave your money in the account to compound, you can use the AER to compare all of your assets accurately.
Using the AER to Compare Investments Let's imagine, for example, that you're picking between two CDs (CDs). Interest on option A is compounded semiannually at a stated rate of 7%. An interest rate of 6.95 percent per day is mentioned for option B. Assume that the terms on both CDs are ten years long. ) (Note: These rates and terms are not actual and are only being used as an example.) The actual CD terms and rates may be shorter and lower.)
Option A's higher interest rate can lead you to believe it is the superior choice at first glance. When calculating the AER, however, you discover that Option B earns higher interest than option A
You'd have $100,649.32 at the end of the term if you'd put $50,000 into Option A, for example (10 years). That's not awful at all. Even though Option B has a lower stated interest rate, you'd collect $102,714.37 at maturity—over $2,000 more than if you had chosen Option A. The AER.1 is to blame for this.
When comparing little amounts, the variations may not be noticeable. For example, if you're talking about a compounded sum of hundreds of thousands of dollars over a long period, it can considerably impact your wealth. they are the variations which may be noticeable
You may save time using an online calculator or spreadsheet instead of manually calculating the AER. If the nominal rate is the interest rate plus the total number of compounding periods in a year, then Google Sheets and Excel offer built-in calculations for AER: 2

Typically, financial organizations will market the most appealing rate to the public. It's more likely that they'll utilize the nominal interest rate when advertising a credit cards or loan because it's lower than the annual percentage rate and thus appears more attractive. Rather, they will tell you that a credit card has a 15% APR even though you will pay 16.18% if compounded daily. When it comes to a savings account, the institution may market the AER or APY to make it appear that they're paying you the best possible rate.
