The annual equivalent rate (AER) is an important metric for individuals and businesses with financial investments, loans, or savings accounts. It is an effective measure of the true interest rate on a particular investment, loan or savings account that takes into account the frequency and amount of compounding. The AER is also referred to as the effective annual interest rate or the annual percentage yield (APY).
The AER will always be higher than the nominal or stated interest rate on the investment, loan or savings account due to compounding. When money is compounded, the interest earned is not only calculated on the principal but also on the past accumulated interest. This means that a higher AER is the result of more frequent compounding of interest which in turn will lead to greater returns on the investment, loan or savings account.
For example, if a loan has a nominal interest rate of three percent, and there is compound interest charged once a year, the AER will be 3%. However, if the same loan had compound interest charged every six months, then the AER would be 3.04% (the amount of interest earned on the total balance including the interest). This example highlights how the AER can be higher than the nominal interest rate because of the more frequent compound interest.
When customers are shopping around for investments, loans or savings accounts, it is important that they understand the AER of each product, as this will enable them to make the most informed decision. Furthermore, when an institution advertises interest rates, they must make sure they are advertising the AER and not just the nominal interest rate so that customers are truly informed. The AER reflects the actual interest rate a customer will receive after accounting for compounding and any other fees.
In conclusion, the annual equivalent rate (AER) is an essential metric for individuals and businesses considering investments, loans, or savings accounts. It provides customers with a better understanding of the true interest rates associated with a particular product and allows them to make the most informed decisions.
