Product Information

If you empty your account of funds before the year ends, you will only earn interest on the amount of time the money was in your account. When looking for a new loan, one of the most important terms you will come across is the annual equivalent rate. That is because understanding how to calculate AER can help you make better-informed decisions about your finances. Exponential notation (e-notation), is a way of expressing numbers that are too large or too small to be conveniently written in decimal form. Now that you know what AER is and how to calculate it let’s look at the pros and cons of using this equation.

AER is important for savers because it gives them a more accurate estimate of the interest they’ll earn on their investment. These products rely on the power of compound interest to grow over time, meaning you should opt for one that offers a high AER. More importantly, AER calculations apply if you plan on keeping the money in your account for an entire year.

Therefore, one of the main things to remember is that EAR takes into account the compounding frequency, giving you a more accurate estimate of the interest. Whether you’re trying to calculate the interest rate on an investment or a loan, you will, as expected, need to become familiar with the frequency of compounding.

Of course, some investments have higher AERs than others, but it ultimately depends on the product and what you’re looking for. However, compounding more often also means that you’ll have to pay more attention to your account to make sure you’re not being charged any unnecessary fees.The 'e' notation is another way to express the scientific notation, written as ae-b instead of a x 10 Most savings accounts compound interest monthly, while some bonds and investment products compound interest daily or even quarterly. However, keep in mind that AER is not the only factor to consider when making an investment decision. However, the actual AER will be lower, and you won’t see the true potential of an investment account before the fees are applied.
