The limit of compounding is reached when it occurs an infinite number of times. The concept of such recurring compounding is called continuous compounding. In the case of compounding, the EAR is always higher than the stated annual interest rate.
The effective interest rate is important in figuring out the best loan or determining which investment offers the highest rate of return. When EAR refers to interest paid to an investor, it works much the same way. Suppose you invest in stock fund A, which has an annual interest rate of 5% that is compounded monthly. Of these two, option A will have a higher overall return or yield because it compounds more often.
The higher the effective annual interest rate is, the better it is for savers/investors, but worse for borrowers. When comparing interest rates on a deposit or a loan, consumers should pay attention to the effective annual interest rate and not the headline-grabbing nominal interest rate. Suppose, for instance, you have two loans, and each has a stated interest rate of 10%, in which one compounds annually and the other compounds twice per year. https://simple-accounting.org/ Even though they both have a stated interest rate of 10%, the effective annual interest rate of the loan that compounds twice per year will be higher. A compounding period is the time period after which the outstanding loan or investment’s interest is added to the principal amount of said loan or investment. The period can be daily, weekly, monthly, quarterly, or semi-annually, depending on the terms agreed upon by the parties involved.
- Simply put, the effective annual interest rate is the rate of interest that an investor can earn (or pay) in a year after taking into consideration compounding.
- This figure is also often included in the prospectus and marketing documents prepared by the security issuers.
- However, if the same investment was instead compounded quarterly, the effective annual rate would then be higher.
- This section explains using a financial calculator to calculate the effective rate.
- Referring to the second question, a bank may choose to advertise a loan with its nominal and effective rates.
A financial product with more compounding periods may have a higher effective annual rate, even if the stated interest rate is lower. This is because interest is being charged more frequently, allowing it to accrue faster. For example, if you have a credit card with a 12% stated annual interest rate that compounds monthly, the effective annual rate will be more than 12%. This rate is particularly essential in understanding the true return on an investment or the total cost of a loan. For both investment opportunities, the bank advertised the nominal interest rate. You now have to calculate the effective annual interest rate by adjusting the nominal rate for the number of compounding periods.
To calculate the EAR, you can use an EAR calculator, which simplifies the process. In this article, we will explain what the EAR is, its formula, how to use an EAR calculator, provide an example, and answer some frequently asked questions. It’s also sometimes called the effective interest rate, annual equivalent rate or effective annual percentage rate (APR). The Effective Annual Rate (EAR) is a valuable tool for individuals and businesses looking to make informed financial decisions.
Compounding is the process whereby interest is added to the principal so that the interest that has been added also earns interest. This compounding can happen on any frequency schedule, from daily to annually. An effective annual interest rate is the actual return on an investment or savings account when the rate is adjusted for compounding over a given period.

It represents the true annual interest rate after accounting for the effect of compounding interest, and it is typically higher than the nominal interest rate. The effectual annual interest rate is a useful way of evaluating the actual return on investment and ascertaining the interest expense paid on a loan. Borrowers need to have a solid understanding of the impact cost of debt has on their business, as it will impact their profitability and solvency. The compound interest rate is the real percentage rate on both the principal amount and the accumulated interest from previous periods on a deposit or loan. This is because investment B has fewer compounding periods and hence a lower real rate.
Is It Better to Have a Higher EAR?
Again, the two components of an EAR are the APR and the number of compounding periods. If you don’t already have it, you can use an APR calculator to find that rate. Yes, essentially the effective interest rate (EIR) and the effective annual rate are the same.
The Effective Annual Rate (EAR) is the rate of interest actually earned on an investment or paid on a loan as a result of compounding the interest over a given period of time. Increasing the number of compounding periods makes the effective annual interest rate increase as time goes by. The effective annual rate calculator is an easy way to restate an interest rate on a loan as an interest rate that is compounded annually. Effective annual rate (EAR), is also called the effective annual interest rate or the annual equivalent rate (AER). A certificate of deposit (CD), a savings account, or a loan offer may be advertised with its nominal interest rate as well as its effective annual interest rate.
For example, the EAR of a 1% Stated Interest Rate compounded quarterly is 1.0038%. Over 1.8 million professionals use CFI to learn accounting, financial analysis, modeling and more. Start with a free account to explore 20+ always-free courses and hundreds of finance templates and cheat sheets.
How to Calculate the Effective Interest Rate?
However, the nominal rate does not suggest compounding the interests that are part of the loan. This is why it is important to understand the concept of this financial tool. Investment B has a higher stated nominal interest rate, but the effective annual interest rate is lower than the effective rate for investment A. This is because Investment B compounds fewer times over the course of the year. If an investor were to put, say, $5 million into one of these investments, the wrong decision would cost more than $5,800 per year. The Effective Annual Rate (EAR) is a tool used to compare the annual interest rates between financial products, considering compounding.
Effective Annual Rate Calculation:
This formula takes into account how often interest is added to the initial amount, which can significantly impact the overall cost or return on an investment or loan.

Notice that we changed the terminology from a return to yield representing the interest rate effectively. Assume you have $5000 of the outstanding balance on a credit card with an APR of 20%. A common mistake would be to think that you would pay $1000 as interest over one year. But the bad news is that a credit card compounds interest daily, so you will need to account for the compounding concept. As evident in the example, investment B has a higher stated nominal rate, but the effective annual interest rate is relatively lower than that of investment A.
Lenders, majorly banks, determine interest rates based on one’s creditworthiness, and the lower the credit score, the higher the real rate can be. This will improve the chances of scoring a lower rate when applying for a loan. This section explains using a financial calculator to calculate the effective rate. Similarly, it is true for investments and interest-bearing accounts to evaluate compounding interest earnings or gains. Interest rate that accounts for compounding effects and reflects the total annualized return on an investment. EAR will always be more than APR unless there is only one compounding period annually.
While the concept works the same whether you’re paying interest or earning it, the terms can be a bit different. For example, savings accounts use the term annual percentage yield (APY) instead of APR, and investment accounts may just provide an annual interest rate. For example, if a deposit with the stated interest rate is 15% compounded monthly, the banks will advertise 16.1% instead of 15%.
Understanding how to calculate the EAR is essential for consumers who want to accurately compare different financial products with different compounding periods. It allows them to identify which financial product offers the best terms. But it is more common to hear about annual percentage rate (APR) (also known as “nominal interest”). To spin it in another light, an investment that is compounded annually will have an effective annual rate that is equal to its nominal rate. However, if the same investment was instead compounded quarterly, the effective annual rate would then be higher. This way, it becomes easy for investors and borrowers to make informed decisions.
However, in reality, interest rates can change frequently and rapidly, often impacting the overall rate of return. Most EAR calculations also do not consider the impact of fees such as transaction fees, service fees, or account maintenance fees. It is also called the effective interest rate, the effective rate, or the annual equivalent rate (AER). With a loan or credit card, the EAR provides you with the true cost of the debt. For relatively low balances and interest rates, it likely won’t be significantly different from the posted APR. But if you have a lot of debt on a credit card, the cost of borrowing could end up being quite a bit more than you think.
